Biologics license application submitted for eptinezumab, an anti-CGRP antibody for migraine prevention

Alder BioPharmaceuticals has submitted a biologics license application (BLA) for eptinezumab, a humanized IgG1 monoclonal antibody that targets calcitonin gene-related peptide (CGRP), for migraine prevention. If the US Food and Drug Administration grants approval, Alder will be on track to launch the drug in Q1 2020. The BLA included data from the PROMISE 1 and PROMISE 2 studies, which evaluated the effects of eptinezumab in episodic migraine patients (n=888) or chronic migraine patients (n=1,072), respectively.  In PROMISE 1, the primary and key secondary endpoints were met, and the safety and tolerability were similar to placebo, while in PROMISE 2, the primary and all key secondary endpoints were met, and the safety and tolerability was consistent with earlier eptinezumab studies.

Alder announced one-year results from the PROMISE 1 study in June 2018, which indicated that, following the first quarterly infusion, episodic migraine patients treated with 300 mg eptinezumab experienced 4.3 fewer monthly migraine days (MMDs) from a baseline of 8 MMDs, compared to 3.2 fewer MMDs for placebo from baseline (p= 0.0001). At one year after the third and fourth quarterly infusions, patients treated with 300 mg eptinezumab experienced further gains in efficacy, with a reduction of 5.2 fewer MMDs compared to 4.0 fewer MMDs for placebo-treated patients.  In addition, ~31% of episodic migraine patients achieved, on average per month, 100% reduction of migraine days from baseline compared to ~ 21% for placebo. New 6-month results from the PROMISE 2 study were also released in June 2018.  These results indicated that, after the first quarterly infusion, chronic migraine patients dosed with 300 mg of eptinezumab experienced 8.2 fewer MMDs, from a baseline of 16 MMDs, compared to 5.6 fewer MMDs for placebo from baseline (p <.0001). A further reduction in MMDs was seen following a second infusion; 8.8 fewer MMDs for patients dosed with 300 mg compared to 6.2 fewer MMDs for those with placebo. In addition, ~ 21% of chronic migraine patients achieved, on average, 100% reduction of MMDs from baseline compared to 9% for placebo after two quarterly infusions of 300 mg of eptinezumab.

If approved, eptinezumab would become the fourth antibody therapeutic for migraine prevention on the US market, following the approval of erenumab-aooe (Aimovig; Novartis), galcanezumab-gnlm (Emgality; Eli Lilly & Company) and fremanezumab-vfrm (Ajovy; Teva Pharmaceuticals) in 2018.

Tepezza (teprotumumab-trbw)

Company: Horizon Therapeutics plc
Date of Approval: January 21, 2020
Treatment for: Thyroid Eye Disease

UNIIY64GQ0KC0A

CAS number1036734-93-6

R-1507 / R1507 / RG-1507 / RG1507 / RO-4858696 / RO-4858696-000 / RO-4858696000 / RO4858696 / RO4858696-000 / RV-001 / RV001

Tepezza (teprotumumab-trbw) is a fully human monoclonal antibody (mAb) and a targeted inhibitor of the insulin-like growth factor 1 receptor (IGF-1R) for the treatment of active thyroid eye disease (TED).

FDA Approves Tepezza (teprotumumab-trbw) for the Treatment of Thyroid Eye Disease (TED) – January 21, 2020

Today, the U.S. Food and Drug Administration (FDA) approved Tepezza (teprotumumab-trbw) for the treatment of adults with thyroid eye disease, a rare condition where the muscles and fatty tissues behind the eye become inflamed, causing the eyes to be pushed forward and bulge outwards (proptosis). Today’s approval represents the first drug approved for the treatment of thyroid eye disease.

“Today’s approval marks an important milestone for the treatment of thyroid eye disease. Currently, there are very limited treatment options for this potentially debilitating disease. This treatment has the potential to alter the course of the disease, potentially sparing patients from needing multiple invasive surgeries by providing an alternative, non surgical treatment option,” said Wiley Chambers, M.D., deputy director of the Division of Transplant and Ophthalmology Products in the FDA’s Center for Drug Evaluation and Research. “Additionally, thyroid eye disease is a rare disease that impacts a small percentage of the population, and for a variety of reasons, treatments for rare diseases are often unavailable. This approval represents important progress in the approval of effective treatments for rare diseases, such as thyroid eye disease.”

Thyroid eye disease is associated with the outward bulging of the eye that can cause a variety of symptoms such as eye pain, double vision, light sensitivity or difficulty closing the eye. This disease impacts a relatively small number of Americans, with more women than men affected. Although this condition impacts relatively few individuals, thyroid eye disease can be incapacitating. For example, the troubling ocular symptoms can lead to the progressive inability of people with thyroid eye disease to perform important daily activities, such as driving or working.

Tepezza was approved based on the results of two studies (Study 1 and 2) consisting of a total of 170 patients with active thyroid eye disease who were randomized to either receive Tepezza or a placebo. Of the patients who were administered Tepezza, 71% in Study 1 and 83% in Study 2 demonstrated a greater than 2 millimeter reduction in proptosis (eye protrusion) as compared to 20% and 10% of subjects who received placebo, respectively.

The most common adverse reactions observed in patients treated with Tepezza are muscle spasm, nausea, alopecia (hair loss), diarrhea, fatigue, hyperglycemia (high blood sugar), hearing loss, dry skin, dysgeusia (altered sense of taste) and headache. Tepezza should not be used if pregnant, and women of child-bearing potential should have their pregnancy status verified prior to beginning treatment and should be counseled on pregnancy prevention during treatment and for 6 months following the last dose of Tepezza.

The FDA granted this application Priority Review, in addition to Fast Track and Breakthrough Therapy Designation. Additionally, Tepezza received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases or conditions. Development of this product was also in part supported by the FDA Orphan Products Grants Program, which provides grants for clinical studies on safety and efficacy of products for use in rare diseases or conditions.

The FDA granted the approval of Tepezza to Horizon Therapeutics Ireland DAC.

Teprotumumab (RG-1507), sold under the brand name Tepezza, is a medication used for the treatment of adults with thyroid eye disease, a rare condition where the muscles and fatty tissues behind the eye become inflamed, causing the eyes to be pushed forward and bulge outwards (proptosis).[1]

The most common adverse reactions observed in people treated with teprotumumab-trbw are muscle spasm, nausea, alopecia (hair loss), diarrhea, fatigue, hyperglycemia (high blood sugar), hearing loss, dry skin, dysgeusia (altered sense of taste) and headache.[1] Teprotumumab-trbw should not be used if pregnant, and women of child-bearing potential should have their pregnancy status verified prior to beginning treatment and should be counseled on pregnancy prevention during treatment and for six months following the last dose of teprotumumab-trbw.[1]

It is a human monoclonal antibody developed by Genmab and Roche. It binds to IGF-1R.

Teprotumumab was first investigated for the treatment of solid and hematologic tumors, including breast cancer, Hodgkin’s and non-Hodgkin’s lymphomanon-small cell lung cancer and sarcoma.[2][3] Although results of phase I and early phase II trials showed promise, research for these indications were discontinued in 2009 by Roche. Phase II trials still in progress were allowed to complete, as the development was halted due to business prioritization rather than safety concerns.

Teprotumumab was subsequently licensed to River Vision Development Corporation in 2012 for research in the treatment of ophthalmic conditions. Horizon Pharma (now Horizon Therapeutics, from hereon Horizon) acquired RVDC in 2017, and will continue clinical trials.[4] It is in phase III trials for Graves’ ophthalmopathy (also known as thyroid eye disease (TED)) and phase I for diabetic macular edema.[5] It was granted Breakthrough TherapyOrphan Drug Status and Fast Track designations by the FDA for Graves’ ophthalmopathy.[6]

In a multicenter randomized trial in patients with active Graves’ ophthalmopathy Teprotumumab was more effective than placebo in reducing the clinical activity score and proptosis.[7] In February 2019 Horizon announced results from a phase 3 confirmatory trial evaluating teprotumumab for the treatment of active thyroid eye disease (TED). The study met its primary endpoint, showing more patients treated with teprotumumab compared with placebo had a meaningful improvement in proptosis, or bulging of the eye: 82.9 percent of teprotumumab patients compared to 9.5 percent of placebo patients achieved the primary endpoint of a 2 mm or more reduction in proptosis (p<0.001). Proptosis is the main cause of morbidity in TED. All secondary endpoints were also met and the safety profile was consistent with the phase 2 study of teprotumumab in TED.[8] On 10th of July 2019 Horizon submitted a Biologics License Application (BLA) to the FDA for teprotumumab for the Treatment of Active Thyroid Eye Disease (TED). Horizon requested priority review for the application – if so granted (FDA has a 60-day review period to decide) it would result in a max. 6 month review process.[9]

History[edit]

Teprotumumab-trbw was approved for use in the United States in January 2020, for the treatment of adults with thyroid eye disease.[1]

Enfortumab vedotin is an antibody-drug conjugate used in the treatment of patients with advanced, treatment-resistant urothelial cancers.3 It is comprised of a fully human monoclonal antibody targeted against Nectin-4 and a microtubule-disrupting chemotherapeutic agent, monomethyl auristatin E (MMAE), joined by a protease-cleavable link.3 It is similar to brentuximab vedotin, another antibody conjugated with MMAE that targets CD-30 instead of Nectin-4.

The clinical development of enfortumab vedotin was the result of a collaboration between Astellas Pharma and Seattle Genetics2 and it was first approved for use in the United States in December 2019 under the brand name PadcevTM.3
The most common side effects for patients taking enfortumab vedotin were fatigue, peripheral neuropathy (nerve damage resulting in tingling or numbness), decreased appetite, rash, alopecia (hair loss), nausea, altered taste, diarrhea, dry eye, pruritis (itching) and dry skin. [4]Enfortumab vedotin[1] (AGS-22M6E) is an antibody-drug conjugate[2] designed for the treatment of cancer expressing Nectin-4.[3]Enfortumab refers to the monoclonal antibody part, and vedotin refers to the payload drug (MMAE) and the linker.

The fully humanized antibody was created by scientists at Agensys (part of Astellas) using Xenomice from Amgen; the linker technology holding the antibody and the toxin together was provided by and licensed from Seattle Genetics.[5]

Results of a phase I clinical trial were reported in 2016.[2]

In December 2019, enfortumab vedotin-ejfv was approved in the United States for the treatment of adult patients with locally advanced or metastatic urothelial cancer who have previously received a programmed death receptor-1 (PD-1) or programmed death ligand 1 (PD-L1) inhibitor and a platinum-containing chemotherapy.[4]

Enfortumab vedotin was approved based on the results of a clinical trial that enrolled 125 patients with locally advanced or metastatic urothelial cancer who received prior treatment with a PD-1 or PD-L1 inhibitor and platinum-based chemotherapy.[4] The overall response rate, reflecting the percentage of patients who had a certain amount of tumor shrinkage, was 44%, with 12% having a complete response and 32% having a partial response.[4] The median duration of response was 7.6 months.[4]

The application for enfortumab vedotin-ejfv was granted accelerated approvalpriority review designation, and breakthrough therapydesignation.[4] The U.S. Food and Drug Administration (FDA) granted the approval of Padcev to Astellas Pharma US Inc.[4]

Indication

Enfortumab vedotin is indicated for the treatment of adult patients with locally advanced or metastatic urothelial cancer who have previously received a programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor, and a platinum-containing chemotherapy in the neoadjuvant/adjuvant, locally advanced, or metastatic setting.3

Associated Conditions

Pharmacodynamics

Enfortumab vedotin is an anti-cancer agent that destroys tumor cells by inhibiting their ability to replicate.3 Patients with moderate to severe hepatic impairment should not use enfortumab vedotin – though it has not been studied in this population, other MMAE-containing antibody-drug conjugates have demonstrated increased rates of adverse effects in patients with moderate-severe hepatic impairment.3 Enfortumab vedotin may also cause significant hyperglycemia leading, in some cases, to diabetic ketoacidosis, and should not be administered to patients with a blood glucose level >250 mg/dl.3

Mechanism of action

Enfortumab vedotin is an antibody-drug conjugate comprised of multiple components.3 It contains a fully human monoclonal antibody directed against Nectin-4, an extracellular adhesion protein which is highly expressed in urothelial cancers,1 attached to a chemotherapeutic microtubule-disrupting agent, monomethyl auristatin E (MMAE). These two components are joined via a protease-cleavable linker. Enfortumab vedotin binds to cells expressing Nectin-4 and the resulting enfortumab-Nectin-4 complex is internalized into the cell. Once inside the cell, MMAE is released from enfortumab vedotin via proteolytic cleavage and goes on to disrupt the microtubule network within the cell, arresting the cell cycle and ultimately inducing apoptosis.3

PADCEV™ (enfortumab vedotin-ejfv) Structural Formula - Illustration

Approximately 4 molecules of MMAE are attached to each antibody molecule. Enfortumab vedotin-ejfv is produced by chemical conjugation of the antibody and small molecule components. The antibody is produced by mammalian (Chinese hamster ovary) cells and the small molecule components are produced by chemical synthesis.

PADCEV (enfortumab vedotin-ejfv) for injection is provided as a sterile, preservative-free, white to off-white lyophilized powder in single-dose vials for intravenous use. PADCEV is supplied as a 20 mg per vial and a 30 mg per vial and requires reconstitution with Sterile Water for Injection, USP, (2.3 mL and 3.3 mL, respectively) resulting in a clear to slightly opalescent, colorless to slightly yellow solution with a final concentration of 10 mg/mL [see DOSAGE AND ADMINISTRATION]. After reconstitution, each vial allows the withdrawal of 2 mL (20 mg) and 3 mL (30 mg). Each mL of reconstituted solution contains 10 mg of enfortumab vedotin-ejfv, histidine (1.4 mg), histidine hydrochloride monohydrate (2.31 mg), polysorbate 20 (0.2 mg) and trehalose dihydrate (55 mg) with a pH of 6.0.

Monoclonal antibody
Treatment of osteoporosis

Osteoporosis agent, Sclerostin activity inhibitor

JAPAN APPROVED 2019/1/8, Evenity

Romosozumab (AMG 785) is a humanized monoclonal antibody that targets sclerostin for the treatment of osteoporosis.[1]

Romosozumab was originally discovered by Chiroscience,[2] which was acquired by Celltech (now owned by UCB).[3] Celltech entered in a partnership with Amgen in 2002 for the product’s development.[4]

In 2016 results from 12 months of a clinical study were reported.[5]

Some results from the FRAME[6] and ARCH clinical studies were reported on in 2017.[7]

Japan’s Ministry of Health, Labor and Welfare has granted a marketing authorization for romosozumab (EVENITY) for the treatment of osteoporosis in patients at high risk of fracture. Developed by Amgen and UCB, romosozumab is a humanized IgG2 monoclonal antibody that targets sclerostin. The approval in Japan is based on results from the Phase 3 FRAME and BRIDGE studies, which included 7,180 postmenopausal women with osteoporosis and 245 men with osteoporosis, respectively.

A biologics license application (BLA) for romosozumab as a treatment of osteoporosis in postmenopausal women at high risk for fracture was submitted to the U.S. Food and Drug Administration (FDA) in July 2016, but additional safety and efficacy data was requested in the FDA’s complete response letter, as announced by Amgen and UCB in July 2017. In July 2018, Amgen and UCB announced that the BLA had been resubmitted. In addition to data from early-stage clinical studies, the original BLA included data from the Phase 3 FRAME study. The resubmitted BLA includes results from the more recent Phase 3 ARCH study, an alendronate-active comparator trial including 4,093 postmenopausal women with osteoporosis who experienced a fracture, and the Phase 3 BRIDGE study. The FDA’s Bone, Reproductive and Urologic Drugs Advisory Committee is scheduled to review data supporting the BLA for romosozumab at a meeting on January 16, 2019.

The European Medicines Agency is also currently reviewing a marketing application for romosozumab.

Commercial production of cell culture-derived products (for example, protein-based products, such as monoclonal antibodies (mAbs)), requires optimization of cell culture parameters in order for the cells to produce enough product to meet clinical and commercial demands. However, when cell culture parameters are optimized for improving productivity of a protein product, it is also necessary to maintain desired quality specifications of the product such as glycosylation profile, aggregate levels, charge heterogeneity, and amino acid sequence integrity (Li, et al., 2010 , mAbs., 2(5):466-477).
      For instance, an increase of over 20% volumetric titer results in a significant improvement in large-scale monoclonal antibody production economics. Additionally, the ability to control the glycan forms of proteins produced in cell culture is important. Glycan species have been shown to significantly influence pharmacokinetics (PK) and pharmacodynamics (PD) of therapeutic proteins such as mAbs. Moreover, the ability to modulate the relative percentage of various glycan species can have drastic results over the behavior of a protein in vivo. For example, increased mannose-5-N-acetylglycosamine-2 (“Man5”) and other high-mannose glycan species have been shown to decrease mAb in vivo half-life (Liu, 2015 , J Pharm Sci., 104(6):1866-84; Goetze et al., 2011 , Glycobiology, 21(7):949-59; and Kanda et al. 2007 , Glycobiology, 17(1):104-18). On the other hand, glycosylated mAbs with mannose-3-N-acetylglycosamine-4 (“G0”) glycan species have been shown to impact antibody dependent cellular cytotoxicity (ADCC).
      Bioreactors have been successfully utilized for the cell-based production of therapeutic proteins using fed-batch, immobilized, perfusion and continuous modes. Strategies, such as the use of temperature, media formulation, including the addition of growth inhibitors, autocrine factors or cyclic mononucleotides, and hyperstimulation by osmolarity stress, have been used to enhance protein production by cells in culture. To the extent that they have worked at all, these approaches have shown only marginal success.
      As such, there is a particular need for improved compositions for use in cell culture for the production of medically or industrially useful products, such as antibodies. Ideally, such compositions and methods for utilizing the same would result in higher titers, modulated (e.g. decreased) high and low molecular weight species, as well as a more favorable glycosylation profile of the derived products in cell culture.
      Throughout this specification, various patents, patent applications and other types of publications (e.g., journal articles, electronic database entries, etc.) are referenced. The disclosure of all patents, patent applications, and other publications cited herein are hereby incorporated by reference in their entirety for all purposes.

breakthrough therapy and orphan drug designations

Approval Status:Approved April 2018

Specific Treatments:X-linked hypophosphatemia

Crysvita (burosumab-twza) is a fibroblast growth factor 23 (FGF23) blocking antibody.

This drug is indicated for the treatment of X-linked hypophosphatemia with radiological evidence of bone disease in children of 1 year of age and older and adolescents with growing skeletons [4].

Burosumab (INN, trade name Crysvita) known as KRN23 is a human monoclonal antibody designed for the treatment of X-linked hypophosphatemia.[1][2][3] Burosumab was approved by the FDA for its intended purpose, in patients aged 1 year and older, on 17 April 2018.[4] The FDA approval fell under both the breakthrough therapy and orphan drug designations.[4]

This drug was developed by Ultragenyx and is in a collaborative license agreement with Kyowa Hakko Kirin.[5]

Burosumab (KRN23) is an entirely human monoclonal IgG1 antibody that binds excess fibroblast growth factor 23 (FGF23) and has been successfully tested in clinical trials in children with X-linked hypophosphatemic rickets [1].

The U.S. Food and Drug Administration approved Crysvita (burosumab) in April 2018. This is the first drug approved to treat adults and children ages 1 year and older with X-linked hypophosphatemia (XLH), which is a rare, inherited form of rickets. X-linked hypophosphatemia causes low circulating levels of phosphorus in the blood. It causes impaired bone growth and development in children and adolescents and issues with bone mineralization throughout a patient’s life [3].

XLH is a serious disease which affects about 3,000 children and 12,000 adults in the United States. Most children with XLH suffer from bowed or bent legs, short stature, bone pain and severe dental pain. Some adults with this condition suffer from persistent, unrelenting discomfort and complications, such as joint pain, impaired mobility, tooth abscesses and hearing loss [3]

Crysvita is specifically indicated for the treatment of X-linked hypophosphatemia (XLH) in adult and pediatric patients 1 year of age and older.

Crysvita is supplied as a subcutaneous injection. The recommended starting dose for pediatrics is 0.8 mg/kg of body weight, rounded to the nearest 10 mg, administered every two weeks. The minimum starting dose is 10 mg up to a maximum dose of 90 mg. After initiation of treatment with Crysvita, measure fasting serum phosphorus every 4 weeks for the first 3 months of treatment, and thereafter as appropriate. If serum phosphorus is above the lower limit of the reference range for age and below 5 mg/dL, continue treatment with the same dose. Follow dose adjustment schedule per the drug label. The recommended dose regimen in adults is 1 mg/kg body weight, rounded to the nearest 10 mg up to a maximum dose of 90 mg, administered every four weeks.  After initiation of treatment with Crysvita, assess fasting serum phosphorus on a monthly basis, measured 2 weeks post-dose, for the first 3 months of treatment, and thereafter as appropriate. If serum phosphorus is within the normal range, continue with the same dose. See drug label for specific dose adjustments.

Mechanism of Action

Crysvita (burosumab-twza) is a fibroblast growth factor 23 (FGF23) blocking antibody. X-linked hypophosphatemia is caused by excess fibroblast growth factor 23 (FGF23) which suppresses renal tubular phosphate reabsorption and the renal production of 1,25 dihydroxy vitamin D. Burosumab-twza binds to and inhibits the biological activity of FGF23 restoring renal phosphate reabsorption and increasing the serum concentration of 1,25 dihydroxy vitamin D.

Tildrakizumab (Ilumya) is a monoclonal antibody designed for the treatment of immunologically mediated inflammatory disorders.[1] In the United States, it is approved for the treatment of moderate-to-severe plaque psoriasis.[2]

Tildrakizumab was designed to block interleukin-23, a cytokine that plays an important role in managing the immune system and autoimmune disease. Originally developed by Schering-Plough, this drug is now part of Merck‘s clinical program, following that company’s acquisition of Schering-Plough.

Sun Pharmaceutical acquired worldwide rights to tildrakizumab for use in all human indications from Merck in exchange for an upfront payment of U.S. $80 million. Upon product approval, Sun Pharmaceutical will be responsible for regulatory activities, including subsequent submissions, pharmacovigilance, post approval studies, manufacturing and commercialization of the approved product. [3]

As of March 2014, the drug was in phase III clinical trials for plaque psoriasis. The two trials enrolled nearly 2000 patients. [4][5]

In 2016, tildrakizumab became the first IL-23p19 inhibitor to demonstrate positive results in Phase-3 clinical trials for the treatment of moderate-to-severe plaque psoriasis, further validating the importance of the role of IL-23 in psoriasis. Sun Pharma signed a licensing pact with Spain’s Almirall for marketing tildrakizumab in Europe [6]

In March 2018, it was approved by the Food and Drug Administration for the treatment of moderate-to-severe plaque psoriasis as an injection for subcutaneous use in the United States.[2]

In 2014, Sun Pharma acquired worldwide rights to tildrakizumab from Merck; upon product approval, Sun Pharma is responsible for regulatory activities, including subsequent submissions, pharmacovigilance, post approval studies, manufacturing and commercialization of the product. In 2016, Almirall sublicensed the product for the development and marketing in Europe for the treatment of psoriasis.

Mechanism of Action

Tildrakizumab is a humanized IgG1/k monoclonal antibody that selectively binds to the p19 subunit of IL-23 and inhibits its interaction with the IL-23 receptor. IL-23 is a naturally occurring cytokine that is involved in inflammatory and immune responses. Tildrakizumab inhibits the release of proinflammatory cytokines and chemokines.

Tildrakizumab (SCH 900222/MK-3222) targets the p19 subunit of IL-23. The mAb was developed by Schering-Plough, which was acquired by Merck & Co. in 2009, and it was then licensed by Merck to Sun Pharmaceutical Industries Ltd in September 2014. Clinical development and regulatory activities will be conducted by Merck, but funded by Sun Pharma. As of October 2014, the safety and efficacy of tildrakizumab are being evaluated in 2 Phase 3 studies that are ongoing but not recruiting patients. Both studies include patients with moderate-to-severe chronic plaque psoriasis and subcutaneously administered drug. The 52-week Phase 3 NCT01729754 study has 4 arms (200 mg tildrakizumab; 100 mg tildrakizumab; 50 mg etanercept; and placebo only), and includes an optional long-term safety extension study. The estimated enrollment is 1050, and the estimated primary completion date is October 2019. The 64-week Phase 3 NCT01722331 study is evaluating the effects of either 200 mg or 100 mg tildrakizumab to placebo; it includes an optional long-term safety extension study. The estimated enrollment is 885, and the estimated primary completion date is June 2015.

Sun Pharma 

Mar 21, 2018, 09:04 ET

MUMBAI, India and PRINCETON, N.J.March 21, 2018 /PRNewswire/ — Sun Pharmaceutical Industries Ltd. (Reuters: SUN.BO, Bloomberg: SUNP IN, NSE: SUNPHARMA, BSE: 524715, “Sun Pharma” and includes its subsidiaries and/or associate companies) today announced that the U.S. Food and Drug Administration (FDA) has approved ILUMYA™ (tildrakizumab-asmn) for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. ILUMYA selectively binds to the p19 subunit of IL-23 and inhibits its interaction with the IL-23 receptor leading to inhibition of the release of pro-inflammatory cytokines and chemokines. ILUMYA is administered at a dose of 100 mg by subcutaneous injection every 12 weeks, after the completion of initial doses at weeks 0 and 4. ILUMYA is contraindicated in patients with a previous serious hypersensitivity reaction to tildrakizumab or to any of the excipients.

“With the approval of ILUMYA and our long-standing commitment in dermatology, we are focused on making a difference for people living with moderate-to-severe plaque psoriasis,” said Abhay Gandhi, President and Chief Executive Officer, North America, Sun Pharma. “We are committed to working with all relevant stakeholders to make ILUMYA available to appropriate people with plaque psoriasis.”

The FDA approval of ILUMYA for the treatment of adults with moderate-to-severe plaque psoriasis was supported by data from the pivotal Phase-3 reSURFACE clinical development program. In the two multicenter, randomized, double-blind, placebo-controlled trials (reSURFACE 1 and reSURFACE 2), 926 adult patients were treated with ILUMYA (N=616) or placebo (N=310). Results from these studies were published in The Lancet in July 2017, with primary endpoints presented at the 25th European Academy of Dermatology and Venereology (EADV) Congress.

Both Phase-3 studies met the primary efficacy endpoints, demonstrating significant clinical improvement with ILUMYA 100 mg compared to placebo when measured by at least 75 percent of skin clearance (Psoriasis Area Sensitivity Index or PASI 75) and Physician’s Global Assessment (PGA) score of “clear” or “minimal” at week 12 after two doses.

Of the patients in the reSURFACE 1 study 74 percent (229 patients) achieved 75 percent skin clearance at week 28 after three doses, and 84 percent of patients who continued receiving ILUMYA 100 mg maintained PASI 75 at week 64 compared to 22 percent of patients who were re-randomized to placebo. In addition, 69 percent of the patients receiving ILUMYA 100 mg who had a PGA score of “clear” or “minimal” at week 28 maintained this response at week 64 compared to 14 percent of patients who were re-randomized to placebo.

IMPORTANT SAFETY INFORMATION (continued)

Cases of angioedema and urticaria occurred in ILUMYA treated subjects in clinical trial. If a serious hypersensitivity reaction occurs, discontinue ILUMYA immediately and initiate appropriate therapy.

ILUMYA may increase the risk of infection. Treatment with ILUMYA should not be initiated in patients with a clinically important active infection until the infection resolves or is adequately treated. Consider the risks and benefits of treatment prior to prescribing ILUMYA in patients with a chronic infection or a history of recurrent infection. Instruct patients receiving ILUMYA to seek medical help if signs or symptoms of clinically important chronic or acute infection occur. If a patient develops a clinically important or serious infection, or is not responding to standard therapy, closely monitor and discontinue ILUMYA until the infection resolves.

Evaluate patients for TB infection prior to initiating treatment with ILUMYA. Initiate treatment of latent TB prior to administering ILUMYA. Monitor patients for signs and symptoms of active TB during and after ILUMYA treatment. Do not administer ILUMYA to patients with active TB infection.

Prior to initiating ILUMYA, consider completion of all age-appropriate immunizations according to current immunization guidelines. Avoid use of live vaccines in patients treated with ILUMYA.

The most common (≥1%) adverse reactions associated with ILUMYA include upper respiratory infections, injection site reactions, and diarrhea.  Adverse reactions that occurred at rates less than 1% but greater than 0.1% in the ILUMYA group and at a higher rate than in the placebo group included dizziness and pain in extremity.

About the Phase-3 reSURFACE Trials
The Phase-3 studies (reSURFACE 1 and reSURFACE 2) were randomized, placebo-controlled, multicenter, three-part studies designed to demonstrate efficacy of ILUMYA in moderate-to-severe plaque psoriasis compared to placebo and comparative drug and to assess safety and tolerability. Part one of the studies randomized patients into three or four treatment arms, including ILUMYA 100 mg, ILUMYA 200 mg, placebo and etanercept (reSURFACE 2 only). After Week 12, patients on placebo were then re-randomized into ILUMYA 100 mg and 200 mg treatment arms to proceed into part two of the studies. Finally, in part three of the reSURFACE 1 study, responders (PASI ≥75) and partial responders (PASI ≥50 and PASI <75) to ILUMYA were re-randomized after Week 28 to continue the same treatment, a different dose of ILUMYA or placebo. Partial and non-responders to etanercept were treated with ILUMYA 200 mg in part three of the reSURFACE 2 study. Patients with guttate, erythrodermic, or pustular psoriasis were excluded.

About Psoriasis
Psoriasis is a chronic immune disease that appears on the skin. It is a non-contagious disorder that speeds the growth cycle of skin cells1 and results in thick scaly areas of skin2. The most common form, affecting about 80 to 90 percent of people living with psoriasis, is called plaque psoriasis3. It appears as red, raised areas of skin covered with flaky white scales, which may be itchy and painful and can crack and bleed2. Many people with plaque psoriasis continue to struggle with the ongoing, persistent nature of this chronic disease.

PF-06650808, is currently being examined in a Ph1 clinical trial (Protocol B7501001).

Notch3
Researchers are also exploring the use of Notch3 targeting. “The Notch pathway plays an important role in the growth of several solid tumours, including breast and ovarian cancer and melanoma,” explained Joerger. “In particular, Notch3 alterations such as gene amplification and upregulation are associated with poor patient survival. Research using Notch3 targeting as an innovative approach to treat solid malignancies included 27 patients unselected for Notch3 who received increasing doses of the anti-Notch3 antibody-drug conjugate PF-06650808. Responses were seen in two breast cancer patients (LBA 30). While preliminary, targeting Notch3 may become a new treatment approach in patients with selected solid tumours.”

Bococizumab[1] (RN316)[2] is a drug in development by Pfizer targeting PCSK9 to reduce LDL cholesterol.[3]

Description

Bococizumab is a monoclonal antibody that inhibits PCSK9, a protein that interferes with the removal of LDL. LDL levels are a major risk factor for cardiovascular disease.

Clinical trials

A phase 2b study of statin patients was presented at the 2014 American College of Cardiology. Monthly or bimonthly injections resulted in significantly reduced LDL-C at week 12.

The Phase 3 SPIRE trials plan to enroll 17,000 patients to measure cardiovascular risk. High risk and statin intolerant subjects will be included.

Japanese filing for Amgen’s PCSK9 inhibitor Repatha


Amgen has filed its closely watched PCSK9 inhibitor Repatha (evolocumab) in Japan for the treatment of high cholesterol.

Repatha is an investigational fully human monoclonal antibody that inhibits proprotein convertase subtilisin/kexin type 9 (PCSK9), a protein that reduces the liver’s ability to remove low-density lipoprotein cholesterol (LDL-C), or ‘bad’ cholesterol, from the blood.

Evolocumab[1] (also known as compound number AMG-145 or AMG145)[2] is a monoclonal antibody designed for the treatment of hyperlipidemia.[3] Evolocumab is a fully human monoclonal antibody that inhibits proprotein convertase subtilisin/kexin type 9 (PCSK9).

PCSK9 is a protein that targets LDL receptors for degradation and thereby reduces the liver’s ability to remove LDL-C, or “bad” cholesterol, from the blood.

Evolocumab, being developed by Amgen scientists, is designed to bind to PCSK9 and inhibit PCSK9 from binding to LDL receptors on the liver surface. In the absence of PCSK9, there are more LDL receptors on the surface of the liver to remove LDL-C from the blood.

Clinical trials

Two trials have been in progress as at mid-2014:

On 23 January 2014 Amgen announced that the Phase 3 GAUSS-2 (Goal Achievement After Utilizing an Anti-PCSK9 Antibody in Statin Intolerant Subjects-2) trial evaluating evolocumab in patients with high cholesterol who cannot tolerate statins met its co-primary endpoints: the percent reduction from baseline in low-density lipoprotein cholesterol (LDL-C) at week 12 and the mean percent reduction from baseline in LDL-C at weeks 10 and 12. The mean percent reductions in LDL-C, or “bad” cholesterol, compared to ezetimibe were consistent with results observed in the Phase 2 GAUSS study.[4][5]

The GAUSS-2 trial evaluated safety, tolerability and efficacy of evolocumab in 307 patients with high cholesterol who could not tolerate effective doses of at least two different statins due to muscle-related side effects. Patients were randomly assigned to one of four treatment groups: subcutaneous evolocumab 140 mg every two weeks and oral placebo daily; subcutaneous evolocumab 420 mg monthly and oral placebo daily; subcutaneous placebo every two weeks and oral ezetimibe 10 mg daily; or subcutaneous placebo monthly and oral ezetimibe 10 mg daily.

Safety was generally balanced across treatment groups. The most common adverse events (> 5 percent in evolocumab combined group) were headache (7.8 percent evolocumab; 8.8 percent ezetimibe), myalgia (7.8 percent evolocumab; 17.6 percent ezetimibe), pain in extremity (6.8 percent evolocumab; 1.0 percent ezetimibe), and muscle spasms (6.3 percent evolocumab; 3.9 percent ezetimibe).

Cholesterol-lowering treatment with a statin as part of follow-up care can help reduce a patient’s risk after myocardial infarction, ischaemic stroke or TIA.

The FOURIER Phase 3 clinical study http://www.fourierstudy.com/ seeks to find out whether lowering cholesterol by an additional 50% might reduce this risk even further. Several sites in the UK are part of this very large clinical study, lasting up to five years, and it is hoped that the study will help guide future clinical practice.

Evolocumab (also formerly known as AMG145, from Amgen) binds to PCSK9, a natural protein produced by the liver. By binding to PCSK9, evolocumab allows the LDL receptor (a protein present in the liver) to move LDL-cholesterol out of the bloodstream more efficiently. This study is designed to see whether treatment of dyslipidemia with evolocumab in people who have experienced a prior myocardial infarction, ischaemic stroke or TIA, and who are taking a highly effective dose of a statin, reduces the risk of recurring or additional cardiovascular events. Participants in this study have clinically evident cardiovascular disease.
