Tolebrutinib (R&D code SAR442168), developed by Principia and later acquired by Sanofi and included in its product line, Tolebrutinib is a BTK inhibitor used to treat cancer, autoimmune diseases such as multiple sclerosis and myasthenia gravis, inflammatory diseases and thromboembolic diseases, etc.,

Tolebrutinib is an orally bioavailable, brain-penetrant, selective, small molecule inhibitor of Bruton’s tyrosine kinase (BTK), with potential immunomodulatory and anti-inflammatory activities. Upon oral administration, tolebrutinib is able to cross the blood-brain barrier and inhibits the activity of BTK both peripherally and in the central nervous system (CNS). This prevents the activation of the B-cell antigen receptor (BCR) signaling pathway, and the resulting immune activation and inflammation. The inhibition of BTK activity also prevents microglial inflammatory signaling in the CNS, and the resulting immune activation, neuroinflammation and neurodegeneration. BTK, a cytoplasmic tyrosine kinase and member of the Tec family of kinases, plays an important role in B lymphocyte development, activation, signaling, proliferation and survival. In addition to B cells, BTK is also expressed in innate immune cells, including macrophages and microglia, and plays an important role in the regulation of microglial inflammatory signaling.

BTK, a member of the Tec family non-receptor tyrosine kinases, is essential for B cell signaling downstream from the B-cell receptor. It is expressed in B cells and other hematopoietic cells such as monocytes, macrophages and mast cells. It functions in various aspects of B cell function that maintain the B cell repertoire (see Gauld S. B. et al., B cell antigen receptor signaling: roles in cell development and disease. Science,

296: 1641 -2. 2002.) B cells pay a role in rheumatoid arthritis (see Perosa F., et ai, CD20-depleting therapy in autoimmune diseases: from basic research to the clinic. / Intern Med. 267:260-77. 2010 and Dorner T, et at. Targeting B cells in immune-mediated

inflammatory disease: a comprehensive review of mechanisms of action and identification of biomarkers. Pharmacol The 125:464-75. 2010 and Honigberg, L., et. ai, The selective BTK inhibitor PCI-32765 blocks B cell and mast cell activation and prevents mouse collagen indiced arthritis. Clin. Immunol. 127 SI :S 111. 2008) and in other autoimmune diseases such as systemic lupus erythematosus and cancers (see Shlomchik M. J., et. ai, The role of B cells in lpr/lpr-induced autoimmunity. /. Exp Med. 180:1295-1306. 1994; Honigberg L. A., The Braton tyrosine kinase inhibitor PCI-32765 blocks B-cell activation and is efficacious in models of autoimmune disease and B-cell malignancy. Proc. Natl. Acad. Sci. 107: 13075-80. 2010; and Mina-Osorio P, et al., Suppression of

glomerulonephritis in lupus-prone NZB x NZW mice by RN486, a selective inhibitor of Bruton’s tyrosine kinase. Arthritis Rheum. 65: 2380-91. 2013).

There is also potential for BTK inhibitors for treating allergic diseases (see Honigberg, L., et. al., The selective BTK inhibitor PCI-32765 blocks B cell and mast cell activation and prevents mouse collagen indiced arthritis. Clin. Immunol. 127 SI :S111. 2008). It was noted that the irreversible inhibitor suppresses passive cutaneous anaphylaxis (PCA) induced by IgE antigen complex in mice. These findings are in agreement with those noted with BTK-mutant mast cells and knockout mice and suggest that BTK inhibitors may be useful for the treatment of asthma, an IgE-dependent allergic disease of the airway.

Accordingly, compounds that inhibit BTK would be useful in treatment for diseases such as autoimmune diseases, inflammatory diseases, and cancer.

FDA Approves Mirvetuximab Soravtansine-gynx for FRα+ Platinum-resistant Ovarian Cancer

November 15, 2022

Kristi Rosa

The FDA has granted accelerated approval to mirvetuximab soravtansine-gynx (Elahere) for the treatment of select patients with folate receptor α–positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer.

The FDA has granted accelerated approval to mirvetuximab soravtansine-gynx (Elahere) for the treatment of adult patients with folate receptor α (Frα)–positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received 1 to 3 prior systemic treatment regimens.1-3

The regulatory agency also gave the green light to the VENTANA FOLR1 (FOLR-2.1) RxDx Assay for use as a companion diagnostic device to identify patients who are eligible to receive the agent. Testing can be done on fresh or archived tissue. Newly diagnosed patients can be tested at diagnosis to determine whether this agent will be an option for them at the time of progression to platinum resistance.

The decision was supported by findings from the phase 3 SORAYA trial (NCT04296890), in which mirvetuximab soravtansine elicited a confirmed investigator-assessed objective response rate (ORR) of 31.7% (95% CI, 22.9%-41.6%); this included a complete response rate of 4.8% and a partial response rate of 26.9%. Moreover, the median duration of response (DOR) was 6.9 months (95% CI, 5.6-9.7) per investigator assessment.

“The approval of Elahere is significant for patients with FRα-positive platinum-resistant ovarian cancer, which is characterized by limited treatment options and poor outcomes,” Ursula Matulonis, MD, chief of the Division of Gynecologic Oncology at the Dana-Farber Cancer Institute, professor of medicine at the Harvard Medical School, and SORAYA co-principal investigator, stated in a press release. “Elahere impressive anti-tumor activity, durability of response, and overall tolerability observed in SORAYA demonstrate the benefit of this new therapeutic option, and I look forward to treating patients with Elahere.”

The global, single-arm SORAYA trial enrolled a total of 106 patients with platinum-resistant ovarian cancer whose tumors expressed high levels of FRα. Patients were allowed to have received up to 3 prior lines of systemic treatment, and all were required to have received bevacizumab (Avastin).

If patients had corneal disorders, ocular conditions in need of ongoing treatment, peripheral neuropathy that was greater than grade 1 in severity, or noninfectious interstitial lung disease, they were excluded.

Study participants received intravenous mirvetuximab soravtansine at 6 mg/kg once every 3 weeks until progressive disease or unacceptable toxicity. Investigators conducted tumor response assessments every 6 weeks for the first 36 weeks, and every 12 weeks thereafter.

Confirmed investigator-assessed ORR served as the primary end point for the research, and the key secondary end point was DOR by RECIST v1.1 criteria.

In the efficacy-evaluable population (n = 104), the median age was 62 years (range, 35-85). Ninety-six percent of patients were White, 2% were Asian, and 2% did not have their race information reported; 2% of patients were Hispanic or Latino. Regarding ECOG performance status, 57% of patients had a status of 0 and the remaining 43% had a status of 1.

Ten percent of patients received 1 prior line of systemic treatment, 39% received 2 prior lines, and 50% received 3 or more prior lines. All patients previously received bevacizumab, as required, and 47% previously received a PARP inhibitor.

The safety of mirvetuximab soravtansine was evaluated in all 106 patients. The median duration of treatment with the agent was 4.2 months (range, 0.7-13.3).

The all-grade toxicities most commonly experienced with mirvetuximab soravtansine included vision impairment (50%), fatigue (49%), increased aspartate aminotransferase (50%), nausea (40%), increased alanine aminotransferase (39%), keratopathy (37%), abdominal pain (36%), decreased lymphocytes (35%), peripheral neuropathy (33%), diarrhea (31%), decreased albumin (31%), constipation (30%), increased alkaline phosphatase (30%), dry eye (27%), decreased magnesium (27%), decreased leukocytes (26%), decreased neutrophils (26%), and decreased hemoglobin (25%).

Thirty-one percent of patients experienced serious adverse reactions with the agent, which included intestinal obstruction (8%), ascites (4%), infection (3%), and pleural effusion (3%). Toxicities proved to be fatalfor 2% of patients, and these included small intestinal obstruction (1%) and pneumonitis (1%).

Twenty percent of patients required dose reductions due to toxicities. Eleven percent of patients discontinued treatment with mirvetuximab soravtansine because of adverse reactions. Toxicities that resulted in more than 2% of patients discontinuing treatment included intestinal obstruction (2%) and thrombocytopenia (2%). One patient discontinued because of visual impairment.

PATENT

WO 2004/058721

https://patentscope.wipo.int/search/en/detail.jsf?docId=WO2004058721

PATENT

PCT Application No. PCT/US2003/040917, filed December 19, 2003 and published as WO2004/058721 on July 15, 2004, the entirety of which is hereby incorporated by reference, describes certain compounds that act as HGF/SF mimetics . Such compounds include terevalefim:

Terevalefim has been demonstrated to be remarkably useful for treatment of a variety of conditions including, for example, fibrotic liver disease, ischemia-reperfusion injury, cerebral infarction, ischemic heart disease, renal disease, lung fibrosis, damaged and/or ischemic organs, transplants or grafts, stroke, cerebrovascular disease, and renal fibrosis, among others (see, for example, WO 2004/058721, WO 2010/005580, US 2011/0230407, US 7879898, and WO 2009/064422, each of which is hereby incorporated by reference.) Exemplary methods of using terevalefim for, eg, treating delayed graft function after kidney transplantation and acute lung injury, are described in WO 2021/087392 and WO 2021/183774, each of which is hereby incorporated by reference. In particular, Terevalefim is or has been the subject of clinical trials for delayed graft function in recipients of a deceased donor kidney (Clinicaltrials.gov identifier: NCT02474667), acute kidney injury after cardiac surgery involving cardiopulmonary bypass (Clinicaltrials.gov identifier: NCT02771509), and COVID -19 pneumonia (Clinicaltrials.gov identifier: NCT04459676). Without wishing to be bound by any particular theory, it is believed that terevalefim’s HGF mimetic capability imparts a variety of beneficial attributes and activities.

[0035] Terevalefim has a CAS Registry No. of 1070881-42-3 and is also known by at least the following names:

● 3-[(1E)-2-(thiophen-2-yl)ethen-1-yl]-1H-pyrazole; and

● (E)-3-[2-(2-thienyl)vinyl]-1H-pyrazole.

Synthesis of Terevalefim

[0057] In some embodiments, the present disclosure provides methods for preparing compounds useful as HGF/SF mimetics, such as terevalefim. A synthesis of terevalefim is described in detail in Example 7 of WO 2004/058721 (“the ‘721 Synthesis”). The ‘721 Synthesis is depicted in Scheme 1:

The ‘721 Synthesis includes certain features which are not desirable for preparation of terevalefim at scale and/or with consistency and/or with suitable purity for use in humans. For example, the ‘721 Synthesis includes preparation of aldehyde compound 1.2, a viscous oil that is difficult to purify with standard techniques. Additionally, the ‘721 Synthesis uses a diethoxyphosphorylacetaldehyde tosylhydrazone reagent in step 1-2. As such, step 1-2 has poor atom economy and results in multiple byproducts that must be purified away from the final product of terevalefim. Step 1-2 also uses sodium hydride, a highly reactive base that can be difficult to control and often results in byproducts that must be purified away from the final product of terevalefim. Such purification steps can be costly and time-consuming. In some embodiments, the present disclosure encompasses the recognition that one or more features of the ‘721 Synthesis can be improved to increase yield and/or increase reliability and/or increase scale and/or reduce byproducts. In some embodiments, the present disclosure provides such a synthesis, as detailed herein.

[0059] In some embodiments, the present disclosure provides a synthesis of terevalefim as depicted in Scheme 2:

Scheme 2

wherein X and R 1 are defined below and in classes and subclasses as described herein.

[0060] It will be appreciated that compounds described herein, eg, compounds in Scheme 2, may be provided and/or utilized in a salt form. For example, compounds which contain a basic nitrogen atom may form a salt with a suitable acid. Alternatively and/or additionally, compounds which contain an acidic moiety, such as a carboxylic acid group, may form a salt with a suitable base. Suitable counterions are well known in the art, eg, see generally, March ‘s Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, MB Smith and J.

March, 5 th Edition, John Wiley & Sons, 2001. All forms of the compounds in Scheme 2 are contemplated by and within the scope of the present disclosure.

Step 2-1 of Scheme 2

[0061] Step 2-1 includes a condensation-elimination reaction between commercially available thiophene-2-carboxaldehyde (1.1) and acetone to provide an α,β-unsaturated ketone compound (2.1).

[0062] In some embodiments, the present disclosure provides a method comprising steps of:

(i) providing compound 1.1:

(ii) contacting compound 1.1 with acetone in the presence of a suitable base,

to compound provide 2.1:

Relacorilant (developmental code name CORT-125134) is an antiglucocorticoid which is under development by Corcept Therapeutics for the treatment of Cushing’s syndrome.[1] It is also under development for the treatment of solid tumors and alcoholism.[1][2] The drug is a nonsteroidal compound and acts as an antagonist of the glucocorticoid receptor.[1] As of December 2017, it is in phase II clinical trials for Cushing’s syndrome and phase I/II clinical studies for solid tumors, while the clinical phase for alcoholism is unknown.[1]

Relacorilant is an orally available antagonist of the glucocorticoid receptor (GR), with potential antineoplastic activity. Upon administration, relacorilant competitively binds to and blocks GRs. This inhibits the activity of GRs, and prevents both the translocation of the ligand-GR complexes to the nucleus and gene expression of GR-associated genes. This decreases the negative effects that result from excess levels of endogenous glucocorticoids, like those seen when tumors overproduce glucocorticoids. In addition, by binding to GRs and preventing their activity, inhibition with CORT125134 also inhibits the proliferation of GR-overexpressing cancer cells. GRs are overexpressed in certain tumor cell types and promote tumor cell proliferation.

Relacorilant (CORT125134)118) is being developed by Corcept Therapeutics, Inc. It is an orally active, high-affinity, selective antagonist of the glucocorticoid receptor that may benefit from the modulation of cortisol activity. In structural optimization, the introduction of a trifluoromethyl group to the 4-position on the pyridyl moiety was found to increase HepG2 tyrosine amino transferase assay potency by a factor of four. Relacorilant is currently being evaluated in a phase II clinical study in patients with Cushing’s syndrome.119)

2-Bromo-4-(trifluoromethyl)pyridine (17) prepared from (E)-4-ethoxy-1,1,1-trifluorobut-3-en-2-one is employed as a key intermediate for the preparation of relacorilant as shown in Scheme 31.120)

The nonselective glucocorticoid receptor (GR) antagonist mifepristone has been approved in the U.S. for the treatment of selected patients with Cushing’s syndrome. While this drug is highly effective, lack of selectivity for GR leads to unwanted side effects in some patients. Optimization of the previously described fused azadecalin series of selective GR antagonists led to the identification of CORT125134, which is currently being evaluated in a phase 2 clinical study in patients with Cushing’s syndrome.

Cushing’s syndrome (CS) is a metabolic disorder caused by chronic hypercortisolism. CS is associated with cardiovascular, metabolic, skeletal and psychological dysfunctions and can be fatal if left untreated. The first-line treatment for all forms of CS is a surgery. However, medical therapy has to be chosen if surgical resection is not an option or is deemed ineffective. Currently available therapeutics are either not selective and have side effects or are only available as an injection (pasireotide).

Imjudo (tremelimumab) in combination with Imfinzi approved in the US for patients with unresectable liver cancer

PUBLISHED24 October 2022

https://www.astrazeneca.com/media-centre/press-releases/2022/imfinzi-and-imjudo-approved-in-advanced-liver-cancer.html

24 October 2022 07:00 BST
 

Approval based on HIMALAYA Phase III trial results which showed single priming dose of Imjudo added to Imfinzi reduced risk of death by 22% vs. sorafenib
 

AstraZeneca’s Imjudo (tremelimumab) in combination with Imfinzi (durvalumab) has been approved in the US for the treatment of adult patients with unresectable hepatocellular carcinoma (HCC), the most common type of liver cancer. The novel dose and schedule of the combination, which includes a single dose of the anti-CTLA-4 antibody Imjudo 300mg added to the anti-PD-L1 antibody Imfinzi 1500mg followed by Imfinzi every four weeks, is called the STRIDE regimen (Single Tremelimumab Regular Interval Durvalumab).

The approval by the US Food and Drug Administration (FDA) was based on positive results from the HIMALAYA Phase III trial. In this trial, patients treated with the combination of Imjudo and Imfinzi experienced a 22% reduction in the risk of death versus sorafenib (based on a hazard ratio [HR] of 0.78, 95% confidence interval [CI] 0.66-0.92 p=0.0035).1 Results were also published in the New England Journal of Medicine Evidence showing that an estimated 31% of patients treated with the combination were still alive after three years, with 20% of patients treated with sorafenib still alive at the same duration of follow-up.2

Liver cancer is the third-leading cause of cancer death and the sixth most commonly diagnosed cancer worldwide.3,4 It is the fastest rising cause of cancer-related deaths in the US, with approximately 36,000 new diagnoses each year.5,6

Ghassan Abou-Alfa, MD, MBA, Attending Physician at Memorial Sloan Kettering Cancer Center (MSK), and principal investigator in the HIMALAYA Phase III trial, said: “Patients with unresectable liver cancer are in need of well-tolerated treatments that can meaningfully extend overall survival. In addition to this regimen demonstrating a favourable three-year survival rate in the HIMALAYA trial, safety data showed no increase in severe liver toxicity or bleeding risk for the combination, important factors for patients with liver cancer who also have advanced liver disease.”

Dave Fredrickson, Executive Vice President, Oncology Business Unit, AstraZeneca, said: “With this first regulatory approval for Imjudo, patients with unresectable liver cancer in the US now have an approved dual immunotherapy treatment regimen that harnesses the potential of CTLA-4 inhibition in a unique combination with a PD-L1 inhibitor to enhance the immune response against their cancer.”

Andrea Wilson Woods, President & Founder, Blue Faery: The Adrienne Wilson Liver Cancer Foundation, said: “In the past, patients living with liver cancer had few treatment options and faced poor prognoses. With today’s approval, we are grateful and optimistic for new, innovative, therapeutic options. These new treatments can improve long-term survival for those living with unresectable hepatocellular carcinoma, the most common form of liver cancer. We appreciate the patients, their families, and the broader liver cancer community who continue to fight for new treatments and advocate for others.”

The safety profiles of the combination of Imjudo added to Imfinzi and for Imfinzi alone were consistent with the known profiles of each medicine, and no new safety signals were identified.

Regulatory applications for Imjudo in combination with Imfinzi are currently under review in Europe, Japan and several other countries for the treatment of patients with advanced liver cancer based on the HIMALAYA results.

Notes

Liver cancer
About 75% of all primary liver cancers in adults are HCC.3 Between 80-90% of all patients with HCC also have cirrhosis.Chronic liver diseases are associated with inflammation that over time can lead to the development of HCC.7

More than half of patients are diagnosed at advanced stages of the disease, often when symptoms first appear.8 A critical unmet need exists for patients with HCC who face limited treatment options.8 The unique immune environment of liver cancer provides clear rationale for investigating medications that harness the power of the immune system to treat HCC.8

HIMALAYA
HIMALAYA was a randomised, open-label, multicentre, global Phase III trial of Imfinzi monotherapy and a regimen comprising a single priming dose of Imjudo 300mg added to Imfinzi 1500mg followed by Imfinzi every four weeks versus sorafenib, a standard-of-care multi-kinase inhibitor.

The trial included a total of 1,324 patients with unresectable, advanced HCC who had not been treated with prior systemic therapy and were not eligible for locoregional therapy (treatment localised to the liver and surrounding tissue).

The trial was conducted in 181 centres across 16 countries, including in the US, Canada, Europe, South America and Asia. The primary endpoint was overall survival (OS) for the combination versus sorafenib and key secondary endpoints included OS for Imfinzi versus sorafenib, objective response rate and progression-free survival (PFS) for the combination and for Imfinzi alone.

Imfinzi
Imfinzi (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumour’s immune-evading tactics and releasing the inhibition of immune responses.

Imfinzi was recently approved to treat patients with advanced biliary tract cancer in the US based on results from the TOPAZ-1 Phase III trial. It is the only approved immunotherapy in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after chemoradiotherapy and is the global standard of care in this setting based on the PACIFIC Phase III trial.

Imfinzi is also approved in the US, EU, Japan, China and many other countries around the world for the treatment of extensive-stage small cell lung cancer (ES-SCLC) based on the CASPIAN Phase III trial. In 2021, updated results from the CASPIAN trial showed Imfinzi plus chemotherapy tripled patient survival at three years versus chemotherapy alone.

Imfinzi is also approved for previously treated patients with advanced bladder cancer in several countries.

Since the first approval in May 2017, more than 100,000 patients have been treated with Imfinzi.

As part of a broad development programme, Imfinzi is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with SCLC, NSCLC, bladder cancer, several gastrointestinal (GI) cancers, ovarian cancer, endometrial cancer, and other solid tumours.

Imfinzi combinations have also demonstrated clinical benefit in metastatic NSCLC in the POSEIDON Phase III trial.

Imjudo
Imjudo (tremelimumab) is a human monoclonal antibody that targets the activity of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). Imjudo blocks the activity of CTLA-4, contributing to T-cell activation, priming the immune response to cancer and fostering cancer cell death.

Beyond HIMALAYA, Imjudo is being tested in combination with Imfinzi across multiple tumour types including locoregional HCC (EMERALD-3), SCLC (ADRIATIC) and bladder cancer (VOLGA and NILE).

Imjudo is also under review by global regulatory authorities in combination with Imfinzi and chemotherapy in 1st-line metastatic NSCLC based on the results of the POSEIDON Phase III trial, which showed the addition of a short course of Imjudo to Imfinzi plus chemotherapy improved both overall and progression-free survival compared to chemotherapy alone.

AstraZeneca in GI cancers
AstraZeneca has a broad development programme for the treatment of GI cancers across several medicines spanning a variety of tumour types and stages of disease. In 2020, GI cancers collectively represented approximately 5.1 million new diagnoses leading to approximately 3.6 million deaths.9

Within this programme, the Company is committed to improving outcomes in gastric, liver, biliary tract, oesophageal, pancreatic, and colorectal cancers.

Imfinzi (durvalumab) is being assessed in combinations in oesophageal and gastric cancers in an extensive development programme spanning early to late-stage disease across settings.

The Company aims to understand the potential of Enhertu (trastuzumab deruxtecan), a HER2-directed antibody drug conjugate, in the two most common GI cancers, colorectal and gastric cancers. Enhertu is jointly developed and commercialised by AstraZeneca and Daiichi Sankyo.

Lynparza (olaparib) is a first-in-class PARP inhibitor with a broad and advanced clinical trial programme across multiple GI tumour types including pancreatic and colorectal cancers. Lynparza is developed and commercialised in collaboration with MSD (Merck & Co., Inc. inside the US and Canada).

AstraZeneca in immuno-oncology (IO)
Immunotherapy is a therapeutic approach designed to stimulate the body’s immune system to attack tumours. The Company’s immuno-oncology (IO) portfolio is anchored in immunotherapies that have been designed to overcome evasion of the anti-tumour immune response. AstraZeneca is invested in using IO approaches that deliver long-term survival for new groups of patients across tumour types.

The Company is pursuing a comprehensive clinical trial programme that includes Imfinzi as a single treatment and in combination with Imjudo (tremelimumab) and other novel antibodies in multiple tumour types, stages of disease, and lines of treatment, and where relevant using the PD-L1 biomarker as a decision-making tool to define the best potential treatment path for a patient.

In addition, the ability to combine the IO portfolio with radiation, chemotherapy, and targeted small molecules from across AstraZeneca’s oncology pipeline, and from research partners, may provide new treatment options across a broad range of tumours.

AstraZeneca in oncology
AstraZeneca is leading a revolution in oncology with the ambition to provide cures for cancer in every form, following the science to understand cancer and all its complexities to discover, develop and deliver life-changing medicines to patients.

The Company’s focus is on some of the most challenging cancers. It is through persistent innovation that AstraZeneca has built one of the most diverse portfolios and pipelines in the industry, with the potential to catalyse changes in the practice of medicine and transform the patient experience.

AstraZeneca has the vision to redefine cancer care and, one day, eliminate cancer as a cause of death.

/////////////////////////////////////////////////////////////////////////////

Mechanism of action

Tremelimumab aims to stimulate an immune system attack on tumors. Cytotoxic T lymphocytes (CTLs) can recognize and destroy cancer cells. However, there is also an inhibitory mechanism (immune checkpoint) that interrupts this destruction. Tremelimumab turns off this inhibitory mechanism and allows CTLs to continue to destroy the cancer cells.[3] This is immune checkpoint blockade.

Tremelimumab binds to the protein CTLA-4, which is expressed on the surface of activated T lymphocytes and inhibits the killing of cancer cells. Tremelimumab blocks the binding of the antigen-presenting cell ligands B7.1 and B7.2 to CTLA-4, resulting in inhibition of B7-CTLA-4-mediated downregulation of T-cell activation; subsequently, B7.1 or B7.2 may interact with another T-cell surface receptor protein, CD28, resulting in a B7-CD28-mediated T-cell activation unopposed by B7-CTLA-4-mediated inhibition.

Unlike Ipilimumab (another fully human anti-CTLA-4 monoclonal antibody), which is an IgG1 isotype, tremelimumab is an IgG2 isotype.[4][5]

Clinical trials

Melanoma

Phase 1 and 2 clinical studies in metastatic melanoma showed some responses.[6] However, based on early interim analysis of phase III data, Pfizer designated tremelimumab as a failure and terminated the trial in April 2008.[1][7]

However, within a year, the survival curves showed separation of the treatment and control groups.[8] The conventional Response Evaluation Criteria in Solid Tumors (RECIST) may underrepresent the merits of immunotherapies. Subsequent immunotherapy trials (e.g. ipilimumab) have used the Immune-Related Response Criteria (irRC) instead.

Mesothelioma

Although it was designated in April 2015 as orphan drug status in mesothelioma,[9] tremelimumab failed to improve lifespan in the phase IIb DETERMINE trial, which assessed the drug as a second or third-line treatment for unresectable malignant mesothelioma.[10][11]

Non-small cell lung cancer

In a phase III trial, AstraZeneca paired tremelimumab with a PD-L1 inhibitor, durvalumab, for the first-line treatment of non-small cell lung cancer.[12] The trial was conducted across 17 countries, and in July 2017, AstraZeneca announced that it had failed to meet its primary endpoint of progression-free survival.[13]

SPI-2012

 Milademetan, also known as DS-3032b or DS-3032, is a potent and selective MDM2 inhibitor with potential antineoplastic activity. Upon oral administration, MDM2 inhibitor DS-3032b binds to, and prevents the binding of MDM2 protein to the transcriptional activation domain of the tumor suppressor protein p53. By preventing this MDM2-p53 interaction, the proteosome-mediated enzymatic degradation of p53 is inhibited and the transcriptional activity of p53 is restored. This results in the restoration of p53 signaling and leads to the p53-mediated induction of tumor cell apoptosis.

DS-3032 (Milademetan) is an orally available, potent and selective inhibitor of the p53-MDM2 (murine double minute 2) interaction. Milademetan binds to, and prevents the binding of MDM2 protein to the transcriptional activation domain of the tumor suppressor protein p53. Milademetan is 10-fold more potent than the first-generation inhibitor nutlin-3a. By preventing this MDM2-p53 interaction, the proteasome-mediated enzymatic degradation of p53 is inhibited and the transcriptional activity of p53 is restored. This results in the restoration of p53 signaling and leads to the p53-mediated induction of tumor cell apoptosis. DS-3032 is currently being evaluated in three phase 1 clinical trials for solid and hematological malignancies, including acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), chronic myeloid leukemia (CML) in blast phase, lymphoma and myelodysplastic syndrome (MDS).

Abstract

Herein, we report the structure and synthesis of the potent MDM2-p53 inhibitor BI-0282. The complex spirooxindole scaffold bearing four stereocenters embedded in a rigid polycyclic ring-system was effectively prepared on a multi-gram scale in only five synthesis steps employing a three-component 1,3-dipolar cycloaddition and a late-stage Davis–Beirut reaction as key steps.

Compound 1

Intermediate 10 (28.8 g, 44.8 mmol) is dissolved in isopropanol (300 mL) and a solution of potassium hydroxide (39.0 g, 694.9 mmol) in water (95 mL) is slowly added. After stirring for 16 h at ambient temperature, the solvents are partially removed under reduced pressure. The residue is diluted with ethyl acetate and treated with a diluted aqueous solution of citric acid. After extraction of the aqueous layer with ethyl acetate, the organic layers are combined, dried with sodium sulfate, and the solvent is removed under reduced pressure. Purification by normal phase column chromatography using dichloromethane and methanol as solvents yields rac-1 (25.8 g, 43.5 mmol) in 70% yield as an amorphous white solid.

Chiral SFC and subsequent purification by reversed phase column chromatography using acetonitrile and methanol as solvents furnishes 1 (BI-0282).

Rac-1 (60 g, 93,3 mmol) was separated by chiral SFC and reversed phase column chromatography to obtain 1 (24.4 g, 40,0 mmol, 43%) as an amorphous white solid.

Chiral HPLC (CHIRALPAK, heptane/isopropanol/trifluoroacetic acid = 70/30/0.1, flow rate 1.0 mL/min, I = 240 mM) tR = 7.8 min (1), and 11.1 min (ent-1). Preparative SFC (CHIRALPAK, carbon dioxide/(isopropanol + 1% diethylamine) = 70/30, flow rate 300 g/min, I = 290 nM).

DAXI Impresses; Approaches FDA Approval

March 2, 2021

Lisette Hilton

Dermatology Times, Dermatology Times, February 2021 (Vol. 42, No. 2), Volume 42, Issue 2

The investigational neuromodulator, evaluated in clinical trials as a treatment for glabellar lines and as a combined therapy for glabellar, dynamic forehead, and lateral canthal lines, is quickly nearing an approval by the FDA.

The long-awaited, longer-lasting neuromodulator drug candidate DaxibotulinumtoxinA for Injection (DAXI), a botulinum toxin type A formulated with a novel peptide excipient, may be nearing FDA approval.

In mid-December 2020, Revance Therapeutics shared results from its phase 2 upper facial lines study (NCT04259086),1 in which investigators looked at DAXI for combined treatment of glabellar, dynamic forehead, and lateral canthal lines.

The authors reported on a multicenter study of 48 patients enrolled to receive 40, 32, and 48 U of DAXI for injection in the glabellar complex, forehead, and lateral canthal areas, respectively. At week 4, nearly 92% of patients achieved an Investigator Global Assessment (IGA) score indicating no or mild wrinkle severity with maximum contraction on their lateral canthal lines. Nearly 96% achieved similar results on their forehead and glabellar lines at week 4.

Wrinkle severity returned to baseline at a median of 7.6 months post treatment, according to the phase 2 study findings.

The treatment was well tolerated in all upper facial regions. The most common adverse event (AE) was injection site erythema, which occurred in 6.3% of patients. The authors reported no eyelid or brow ptosis.

This was Revance’s first DAXI study on not just glabellar lines but also on forehead and periocular lines, or crow’s-feet, according to Jeffrey S. Dover, MD, FRCPC, a phase 2 study investigator and a dermatologist at SkinCare Physicians in Chestnut Hill, Massachusetts. “I think this is yet more evidence that the Revance neuromodulator produces an impressive effect on lines of negative facial expression and lasts longer than any of the other neuromodulators approved by the FDA thus far,” said Dover.

Dermatologic Surgery published 2 papers on the investigational neuromodulator in January 2021. In one study,2 investigators evaluated the use of up to 3 DAXI treatments for moderate or severe glabellar lines. They focused on data from SAKURA 1 and 2 (NCT03014622 and NCT03014635), two identical phase 3, open label, multicenter studies in which investigators evaluated single and repeat treatment of the glabellar lines with 40 U of DAXI.

The authors reported on safety results for nearly 2700 patients, including 882 who received a second treatment and 568 who got DAXI a third time. Treatment-related AEs, which were generally mild and resolved, occurred in 17.8% of patients. Eyelid ptosis occurred in 0.9% of treatments.

Investigators of 2 other studies3,4 focused on DAXI efficacy among nearly 2700 subjects enrolled in Revance’s preceding pivotal trials. Participants received repeat treatments when they returned to baseline on the IGA–Frown Wrinkle Severity (FWS) and IGA–Patient Frown Winkle Severity (PFWS) scales at 12 weeks and up to 36 weeks after treatment.

More than 96% of patients achieved no or mild severity in glabellar wrinkles on the IGA- FWS scale after each of the 3 treatments, with peak responses between weeks 2 to 4, and about one-third or more saw no or mild severity at week 24. Response rates reached highs of 92% or more at weeks 2 to 4 on the IGA-PFWS scale.

“The median duration for return to moderate or severe severity was 24 weeks,” the authors said. “If approved, I believe daxibotulinumtoxinA will change the landscape of neuromodulators significantly. The approved ones all last 3 months. They all give nice results and have few adverse effects,” Dover said.

He and other investigators have seen no rise in AEs, and those that did occur lasted no longer than those of Botox, he said.

Revance appears to be preparing for approval. The company announced on December 22, 2020, that it has a strategic commercial manufacturing agreement with Ajinomoto Bio- Pharma Services for the supply of DAXI.5

As of November 24, 2020, the FDA had deferred a decision on the neuromodulator because the required factory inspection could not be conducted due to travel restrictions related to coronavirus disease 2019.6 The FDA did not indicate any other issues.

Ozoralizumab is a humanized monoclonal antibody designed for the treatment of inflammatory diseases.[1]

Ozoralizumab was developed by Pfizer Inc, and now belongs to Ablynx NV. Ablynx has licensed the rights to the antibody in China to Eddingpharm.

Ozoralizumab has been used in trials studying the treatment of Rheumatoid Arthritis and Active Rheumatoid Arthritis.

Ozoralizumab is a 38 kDa humanized trivalent bispecific construct consisting of two anti-TNFα NANOBODIES® and anti-HSA NANOBODY® that was generated at Ablynx by a previously described method (23). Llamas were immunized with human TNFα and human muscle extract, which is rich in HSA, to induce the formation of anti-TNFα VHH and anti-HSA VHH. Both the anti-TNFα VHH and anti-HSA VHH were humanized by a complementary determining regions (CDR) grafting approach in which the CDR of the gene encoding llama VHH was grafted onto the most homologous human VHH framework sequence. Since binding to serum albumin prolongs the half-life of VHH (23, 26, 27), an anti-HSA VHH which efficiently binds murine serum albumin as well was incorporated into the two anti-TNFα VHHs. The three components were fused using a flexible Gly-Ser linker.

EXAMPLES

Example 1: Synthesis of compound I from (S) ethyl 2-(benzyloxycarbonylamino) 4-(neopentyloxysulfonyl)butanoate

Step (a): (S) neopentyl 3-(benzylox carbonylamino) 4-hydroxybutane 1-sulfonate B

B

(S) ethyl 2-(benzyloxycarbonylamino) 4-(neopentyloxysulfonyl)butanoate A (41.55g, 100.0 mmol, 1.0 eq.) is added dropwise onto a 2M solution of LiBH4 in THF (50 mL, 44.8 g, 100.0 mmol, 1.0 eq.). The addition is performed at room temperature over a 3 hrs period. At the end of the addition, the mixture is stirred at room temperature until conversion is complete (A<1%). Addition of toluene, followed by hydrolysis with HC1, washings of the organic layer with NaHC03 and water, and concentration under vacuum lead to the desired product as a pale yellow oil in quantitative yield (ee = 98%), which slowly crystallises at room temperature in 4 or 5 days.

As B was found to have a very low melting point by DSC analysis, it was not possible to isolate it as a solid by simple crystallisation. It was decided to let it in solution and use it without further purification in the following step.

Step (b): (S) neopentyl 3-(benzyloxycarbonylamino) 4-(methylsulfonyloxy)butane 1-sulfonate

C

C

A solution of B (57.64 g, 154.34 mmol, 1.0 eq.) in toluene (115 mL, 2.0 vol.) is diluted with MTBE (173 mL, 3.0 vol.) at room temperature. Mesyl chloride (17.9 mL, 26.5 g, 231.50 mmol, 1.5 eq.) is then added at room temperature and the homogeneous mixture is cooled to 10°C. The addition of triethylamine (43.0 mL, 31.2 g, 308.67 mmol, 2.0 eq.) is performed at T<20°C. At the end of the addition, the mixture is stirred at 10°C until conversion is complete (B<1%). After hydrolysis with diluted HCl, the organic layer is washed with NaHC03, water and brine, followed by a partial concentration under reduced pressure. The corresponding mesylate is then crystallised by addition of heptanes (5.0 vol.) at 40°C. After cooling, filtration and drying, the expected product is isolated as a whitish solid in 92.5% yield and with a very high chemical purity (98%).

Step (c): (S) 2-(benzyloxycarbonylamino) 4-(neopentyloxysulfonyl)butyl thioacetate D

D

A solution of mesylate C (81.3 g, 180.05 mmol, 1.0 eq.) in acetone (203 mL, 2.5 vol.) is added dropwise to a suspension of potassium thioacetate (41.1 g, 360.1 mmol, 2.0 eq.) in acetone (203 mL, 2.5 vol.) at room temperature and over a period of 2 hrs. The reaction mixture is stirred at room temperature until conversion is complete (C<1%). After filtration of the salts and addition of toluene (4.0 vol.), acetone is removed by distillation under reduced pressure at 25°C. The solution is then treated with active charcoal and concentrated to 2.0 volumes. Slow addition of heptane (5.0 vol.) at room temperature, followed by cooling at 0°C, filtration and drying at 45°C, provides the expected product as a whitish solid in 78.2% yield and with a very high chemical purity (98%).

Step (d): (3S,3S’) neopentyl 4,4′-disulfanediylbis(3-(benzyloxycarbonylamino)butane 1-sulfonate) E

E

A solution of D (59.16 g, 137.1 mmol, 1.0 eq.) suspended in ethanol (203 mL, 2.5 vol.) is cooled to 0°C. 20% sodium hydroxide (25.1 mL, 150.8 mmol, 1.1 eq.) diluted with water

(16.9 mL, 0.285 vol.) is then added dropwise to the suspension by keeping the temperature below 10°C. The reaction mixture is warmed to room temperature and stirred until conversion is complete (D<1%). The intermediate thiol reacts at room temperature with a solution of iodine (20.9 g, 82.3 mmol, 0.6 eq.) in ethanol (118 mL, 2.0 vol.). The reaction is complete at the end of the addition of the oxidizing agent. After addition of a Na2S205 (13.0 g, 68.5 mmol, 0.5 eq.) aqueous solution (118 mL, 2.0 vol.) to reduce the excess of residual iodine, ethanol is removed by distillation under reduced pressure at 40°C. Addition of water (3.0 vol.) at room temperature, followed by cooling at 0°C, filtration and drying at 45-50°C, provides the expected dimer as a white solid in 98.3% yield and with a very high chemical purity (97.0%). The amount of iodide ions, coming from the reduction of iodine, is checked in the sample by potentiometric assay.

Compound I

A solution of E (44.0 g, 56.6 mmol, 1.0 eq.) in TFA (220 mL, 5.0 vol.) and anisole (44 mL, 1.0 vol.) is heated to reflux (75°C) and the reaction mixture is stirred in these conditions until conversion is complete (E<1%). TFA is removed by distillation under reduced pressure at 50°C. Slow addition of MTBE (5.0 vol.) at room temperature makes the expected product precipitate. After trituration, filtration and washing with MTBE (1.0 vol.), the crude solid is suspended in methanol (220 mL, 5.0 vol.). New trituration, filtration and washing with MTBE (1.0 vol.), followed by drying under reduced pressure, provides compound I as a white solid in 92.5% yield.

TAS-120, TAS 120, TAS120; Futibatinib

Futibatinib, also known as TAS-120 is an orally bioavailable inhibitor of the fibroblast growth factor receptor (FGFR) with potential antineoplastic activity. FGFR inhibitor TAS-120 selectively and irreversibly binds to and inhibits FGFR, which may result in the inhibition of both the FGFR-mediated signal transduction pathway and tumor cell proliferation, and increased cell death in FGFR-overexpressing tumor cells. FGFR is a receptor tyrosine kinase essential to tumor cell proliferation, differentiation and survival and its expression is upregulated in many tumor cell types.
