The FDA approved reslizumab for use with other asthma medicines for the maintenance treatment of severe asthma in patients aged 18 years and older on March 23, 2016. Cinqair is approved for patients who have a history of severe asthma attacks (exacerbations) despite receiving their current asthma medicines.
Teva Announces FDA Acceptance of the Biologics License Application for Reslizumab
Investigational Biologic for the Treatment of Inadequately Controlled Asthma in Patients with Elevated Blood Eosinophils Accepted for Review
JERUSALEM–(BUSINESS WIRE)–Jun. 15, 2015– Teva Pharmaceutical Industries Ltd., (NYSE: TEVA) announced today that the U.S. Food and Drug Administration (FDA) has accepted for review the Biologics License Application (BLA) for reslizumab, the company’s investigational humanized monoclonal antibody (mAb) which targets interleukin-5 (IL-5), for the treatment of inadequately controlled asthma in adult and adolescent patients with elevated blood eosinophils, despite an inhaled corticosteroid (ICS)-based regimen.
“Despite currently available medicines, uncontrolled asthma remains a serious problem for patients, physicians and healthcare systems, highlighting the need for targeted new treatment options,” said Dr. Michael Hayden, President of Global R&D and Chief Scientific Officer at Teva Pharmaceutical Industries Ltd. “The reslizumab BLA filing acceptance represents a significant milestone for Teva as we work toward serving a specific asthma patient population that is defined by elevated blood eosinophil levels and inadequately controlled symptoms despite standard of care therapy. In clinical trials, patients treated with reslizumab showed significant reductions in the rate of asthma exacerbations and significant improvement in lung function. If approved, we believe reslizumab will serve as an important new targeted treatment option to achieve better asthma control for patients with eosinophil-mediated disease.”
The BLA for reslizumab includes data from Teva’s Phase III BREATH clinical trial program. The program consisted of four separate placebo-controlled Phase III trials involving more than 1,700 adult and adolescent asthma patients with elevated blood eosinophils, whose symptoms were inadequately controlled with inhaled corticosteroid-based therapies. Results from these studies demonstrated that reslizumab, in comparison to placebo, reduced asthma exacerbation rates by at least half and provided significant improvement in lung function and other secondary measures of asthma control when added to an existing ICS-based therapy. Common adverse events in the reslizumab treatment group were comparable to placebo and included worsening of asthma, nasopharyngitis, upper respiratory infections, sinusitis, influenza and headache. Two anaphylactic reactions were reported and resolved following medical treatment at the study site.
Results from the reslizumab BREATH program were recently presented at the American Thoracic Society 2015 Annual Meeting and the American Academy of Allergy, Asthma and Immunology 2015 Annual Meeting, in addition to being published in The Lancet Respiratory Medicine. The BLA for reslizumab has been accepted for filing by the FDA for standard review, with FDA Regulatory Action expected in March 2016.
Reslizumab is an investigational humanized monoclonal antibody which targets interleukin-5 (IL-5). IL-5 is a key cytokine involved in the maturation, recruitment, and activation of eosinophils, which are inflammatory white blood cells implicated in a number of diseases, such as asthma. Elevated levels of blood eosinophils are a risk factor for future asthma exacerbations. Reslizumab binds circulating IL-5 thereby preventing IL-5 from binding to its receptor.
Asthma is a chronic (long term) disease usually characterized by airway inflammation and narrowing of the airways, which can vary over time. Asthma may cause recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath and coughing that often occurs at night or early in the morning. Without appropriate treatment, asthma symptoms may become more severe and result in an asthma attack, which can lead to hospitalization and even death.
Eosinophils are a type of white blood cell that are present at elevated levels in the lungs and blood of many asthmatics. Evidence shows that eosinophils play an active role in the pathogenesis of the disease. IL-5 has been shown to play a crucial role in maturation, growth and activation of eosinophils. Increased levels of eosinophils in the sputum and blood have been shown to correlate with severity and frequency of asthma exacerbations.

The U.S. Food and Drug Administration today approved Cinqair (reslizumab) for use with other asthma medicines for the maintenance treatment of severe asthma in patients aged 18 years and older. Cinqair is approved for patients who have a history of severe asthma attacks (exacerbations) despite receiving their current asthma medicines.
Asthma is a chronic disease that causes inflammation in the airways of the lungs. During an asthma attack, airways become narrow making it hard to breathe. Severe asthma attacks can lead to asthma-related hospitalizations because these attacks can be serious and even life-threatening. According to the Centers for Disease Control and Prevention, as of 2013, more than 22 million people in the U.S. have asthma, and there are more than 400,000 asthma-related hospitalizations each year.
“Health care providers and their patients with severe asthma now have another treatment option to consider when the disease is not well controlled by their current asthma therapies,” said Badrul Chowdhury, M.D., Ph.D., director of the Division of Pulmonary, Allergy, and Rheumatology Products in the FDA’s Center for Drug Evaluation and Research.
Cinqair is administered once every four weeks via intravenous infusion by a health care professional in a clinical setting prepared to manage anaphylaxis. Cinqair is a humanized interleukin-5 antagonist monoclonal antibody produced by recombinant DNA technology in murine myeloma non-secreting 0 (NS0) cells. Cinqair reduces severe asthma attacks by reducing the levels of blood eosinophils, a type of white blood cell that contributes to the development of asthma.
The safety and efficacy of Cinqair were established in four double-blind, randomized, placebo‑controlled trials in patients with severe asthma on currently available therapies. Cinqair or a placebo was administered to patients every four weeks as an add-on asthma treatment. Compared with placebo, patients with severe asthma receiving Cinqair had fewer asthma attacks, and a longer time to the first attack. In addition, treatment with Cinqair resulted in a significant improvement in lung function, as measured by the volume of air exhaled by patients in one second.
Cinqair can cause serious side effects including allergic (hypersensitivity) reactions. These reactions can be life-threatening. The most common side effects in clinical trials for Cinqair included anaphylaxis, cancer, and muscle pain.
Cinqair is made by Teva Pharmaceuticals in Frazer, Pennsylvania.

Blinatumomab, AMG-103, MEDI-538, MT-103,
A bispecific CD19-directed CD3 T-cell engager used to treat philadelphia chromosome-negative relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL).
1: PN: WO2005052004 SEQID: 1 claimed protein
Blinatumomab (trade name Blincyto, previously known as AMG103) is a biopharmaceutical drug used as a second-line treatmentfor Philadelphia chromosome-negative relapsed or refractory acute lymphoblastic leukemia. It belongs to a class of constructedmonoclonal antibodies, bi-specific T-cell engagers (BiTEs), that exert action selectively and direct the human immune system to act against tumor cells. Blinatumomab specifically targets the CD19 antigen present on B cells. In December 2014 it was approved by the US Food and Drug Administration under the accelerated approval program; marketing authorization depended on the outcome of clinical trials that were ongoing at the time of approval. When it launched, blinatumomab was priced at $178,000 per year in the United States; only about 1,000 people were eligible to take the drug, based on its label.
Mechanism of action
Blinatumomab enables a patient’s T cells to recognize malignant B cells. A molecule of blinatumomab combines two binding sites: aCD3 site for T cells and a CD19 site for the target B cells. CD3 is part of the T cell receptor. The drug works by linking these two cell types and activating the T cell to exert cytotoxic activity on the target cell. CD3 and CD19 are expressed in both pediatric and adult patients, making blinatumomab a potential therapeutic option for both pediatric and adult populations.
The drug was developed by a German-American company Micromet, Inc. in cooperation with Lonza; Micromet was later purchased byAmgen, which has furthered the drug’s clinical trials. In July 2014, the FDA granted breakthrough therapy status to blinatumomab for the treatment of acute lymphoblastic leukemia (ALL). In October 2014, Amgen’s Biologics License Application for blinatumomab was granted priority review designation by the FDA, thus establishing a deadline of May 19, 2015 for completion of the FDA review process.
On December 3, 2014, the drug was approved for use in the United States to treat Philadelphia chromosome-negative relapsed or refractory acute lymphoblastic leukemia under the FDA‘s accelerated approval program; marketing authorization depended on the outcome of clinical trials that were ongoing at the time of approval.
When blinatumomab was approved, Amgen announced that the price for the drug would be $178,000 per year, which made it the most expensive cancer drug on the market. Merck’s pembrolizumab was priced at $150,000 per year when it launched; unlike that drug and others, only about 1,000 people can be given the drug, based on its label.
Peter Bach, director of the Center for Health Policy and Outcomes at Memorial Sloan-Kettering Cancer Center, has calculated that according to “value-based pricing,” assuming that the value of a year of life is $120,000 with a 15% “toxicity discount,” the market price of blinaumomab should be $12,612 a month, compared to the market price of $64,260 a month. A representative of Amgen said, “The price of Blincyto reflects the significant clinical, economic and humanistic value of the product to patients and the health-care system. The price also reflects the complexity of developing, manufacturing and reliably supplying innovative biologic medicines.”

For Idiopathic Pulmonary Fibrosis, Focal Segmental Glomerulosclerosis,and Cancer
An anti-TGF-beta antibody in phase I clinical trials (2011) for treatment-resistant primary focal segmental glomerulosclerosis.
A pan-specific, recombinant, fully human monoclonal antibody directed against human transforming growth factor (TGF) -beta 1, 2 and 3 with potential antineoplastic activity. Fresolimumab binds to and inhibits the activity of all isoforms of TGF-beta, which may result in the inhibition of tumor cell growth, angiogenesis, and migration. TGF-beta, a cytokine often over-expressed in various malignancies, may play an important role in promoting the growth, progression, and migration of tumor cells.
Fresolimumab (GC1008) is a human monoclonal antibody and an immunomodulator. It is intended for the treatment of idiopathic pulmonary fibrosis (IPF), focal segmental glomerulosclerosis, and cancer (kidney cancer and melanoma).
Fresolimumab was discovered by Cambridge Antibody Technology (CAT) scientists and was one of a pair of candidate drugs that were identified for the treatment of the fatal condition scleroderma. CAT chose to co-develop the two drugs metelimumab (CAT-192) and fresolimumab with Genzyme. During early development, around 2004, CAT decided to drop development of metelimumab in favour of fresolimumab.
As of June 2011 the drug was being tested in humans (clinical trials) against IPF, renal disease, and cancer. On 13 August 2012, Genzyme applied to begin a Phase 2 clinical trial in primary focal segmental glomerulosclerosis comparing fresolimumab versus placebo.
As of July 2014, Sanofi-Aventis continue to list fresolimumab in their research and development portfolio under Phase II development.

Approved nov 30 2012
A SLAMF7-directed immunostimulatory antibody used to treat multiple myeloma.
Elotuzumab (brand name Empliciti, previously known as HuLuc63) is a humanized monoclonal antibody used in relapsed multiple myeloma. The package insert denotes its mechanism as a SLAMF7-directed (also known as CD 319) immunostimulatory antibody.
Approvals and indications
In May 2014, it was granted “Breakthrough Therapy” designation by the FDA.  On November 30, 2015, FDA approved elotuzumab as a treatment for patients with multiple myeloma who have received one to three prior medications. Elotuzumab was labeled for use with lenalidomide and dexamethasone. Each intravenous injection of elotuzumab should be premedicated with dexamethasone, diphenhydramine, ranitidine and acetaminophen.
Elotuzumab is APPROVED for safety and efficacy in combination with lenalidomide and dexamethasone.
Monoclonal antibody therapy for multiple myeloma, a malignancy of plasma cells, was not very clinically efficacious until the development of cell surface glycoprotein CS1 targeting humanized immunoglobulin G1 monoclonal antibody – Elotuzumab. Elotuzumab is currently APPROVED in relapsed multiple myeloma.
Elotuzumab (HuLuc63) binds to CS1 antigens, highly expressed by multiple myeloma cells but minimally present on normal cells. The binding of elotuzumab to CS1 triggers antibody dependent cellular cytotoxicity in tumor cells expressing CS1. CS1 is a cell surface glycoprotein that belongs to the CD2 subset of immunoglobulin superfamily (IgSF). Preclinical studies showed that elotuzumab initiates cell lysis at high rates. The action of elotuzumab was found to be enhanced when multiple myeloma cells were pretreated with sub-therapeutic doses of lenalidomide and bortezomib. The impressive preclinical findings prompted investigation and analysis of elotuzumab in phase I and phase II studies in combination with lenalidomide and bortezomib.
Elotuzumab As Part of Combination Therapy: Clinical Trial Results
Elotuzumab showed manageable side effect profile and was well tolerated in a population of relapsed/refractory multiple myeloma patients, when treated with intravenous elotuzumab as single agent therapy. Lets’ take a look at how elotuzumab fared in combination therapy trials,
In phase I trial of elotuzumab in combination with Velcade/bortezomib in patients with relapsed/refractory myeloma, the overall response rate was 48% and activity was observed in patients whose disease had stopped responding to Velcade previously. The trial results found that elotuzumab enhanced Velcade activity.
A phase I/II trial in combination with lenalidomide and dexamethasone in refractory/relapsed multiple myeloma patients showed that 82% of patients responded to treatment with a partial response or better and 12% of patients showed complete response. Patients who had received only one prior therapy showed 91% response rate with elotuzumab in combination with lenalidomide and dexamethasone.
Phase I/II trials of the antibody drug has been very impressive and the drug is currently into Phase III trials. Two phase III trials are investigating whether addition of elotuzumab with Revlimid and low dose dexamethasone would increase the time to disease progression. Another phase III trial (ELOQUENT 2) is investigating and comparing safety and efficacy of lenalidomide plus low dose dexamethasone with or without 10mg/kg of elotuzumab in patients with relapsed/refractory multiple myeloma.
Elotuzumab is being investigated in many other trials too. It is being evaluated in combination with Revlimid and low-dose dexamethasone in multiple myeloma patients with various levels of kidney functions, while another phase II study is investigating elotuzumab’s efficacy in patients with high-risk smoldering myeloma.
The main target of multiple myeloma drug development is to satisfy the unmet need for drugs that would improve survival rates. Elotuzumab is an example that mandates much interest in this area and should be followed with diligence.
Empliciti will be sold in the U.S. in two vials sizes: A smaller vial that contains 300 mg of the drug, and a larger vial that contains 400 mg.
Bristol-Myers Squibb has informed The Beacon that the wholesale price per vial of Empliciti will be $1,776 for the 300 mg vial and $2,368 for the 400 mg vial.
Using these prices and an assumed patient weight of between 154 and 176 pounds, Empliciti will cost $18,944 per four-week cycle for each of the first two cycles of treatment, and $9,472 per cycle thereafter. This means, in turn, that Empliciti’s cost per year will be $142,080 in the first year and $123,136 in subsequent years.
In comparison, Velcade costs between $4,800 and $8,500 per four-week cycle, depending on how often it is dosed. Ninlaro costs $8,670 per four-week cycle. And Kyprolis costs $10,500 per four-week cycle at the standard (20 – 27 mg/m2) dose.
Additional details about the FDA approval of Empliciti can be found in this press release from the FDA, a related press release from Bristol-Myers Squibb and AbbVie, and the full Empliciti prescribing information.
The results of the ELOQUENT-2 trial were published in Lonial, S. et al., “Elotuzumab Therapy for Relapsed or Refractory Multiple Myeloma,” The New England Journal of Medicine, June 2, 2015 (abstract). Slides from the ASCO presentation summarizing the ELOQUENT-2 results can be viewed here (PDF, courtesy of Dr. Lonial). This Beacon news article provides an in-depth look at the trial results.

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

The U.S. Food and Drug Administration today expanded the approved use of Opdivo (nivolumab) to treat patients with advanced (metastatic) squamous non-small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy.
Lung cancer is the leading cause of cancer death in the United States, with an estimated 224,210 new diagnoses and 159,260 deaths in 2014. The most common type of lung cancer, NSCLC affects seven out of eight lung cancer patients, occurring when cancer forms in the cells of the lung.
Opdivo works by inhibiting the cellular pathway known as PD-1 protein on cells that blocks the body’s immune system from attacking cancerous cells. Opdivo is intended for patients who have previously been treated with platinum-based chemotherapy.
“The FDA worked proactively with the company to facilitate the early submission and review of this important clinical trial when results first became available in late December 2014,” said Richard Pazdur, M.D., director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “This approval will provide patients and health care providers knowledge of the survival advantage associated with Opdivo and will help guide patient care and future lung cancer trials.”
Opdivo’s efficacy to treat squamous NSCLC was established in a randomized trial of 272 participants, of whom 135 received Opdivo and 137 received docetaxel. The trial was designed to measure the amount of time participants lived after starting treatment (overall survival). On average, participants who received Opdivo lived 3.2 months longer than those participants who received docetaxel.
The safety and efficacy of Opdivo to treat squamous NSCLC was supported by a single-arm trial of 117 participants who had progressed after receiving a platinum-based therapy and at least one additional systemic regimen. The study was designed to measure objective response rate (ORR), or the percentage of participants who experienced partial shrinkage or complete disappearance of the tumor. Results showed 15 percent of participants experienced ORR, of whom 59 percent had response durations of six months or longer.
The most common side effects of Opdivo are fatigue, shortness of breath, musculoskeletal pain, decreased appetite, cough, nausea and constipation. The most serious side effects are severe immune-mediated side effects involving healthy organs, including the lung, colon, liver, kidneys and hormone-producing glands.
Opdivo for squamous NSCLC was reviewed under the FDA’s priority review program, which provides for an expedited review of drugs that treat serious conditions and, if approved, would provide significant improvement in safety or effectiveness in the treatment of a serious condition. Opdivo is being approved more than three months ahead of the prescription drug user fee goal date of June 22, 2015, the date when the agency was scheduled to complete its review of the application.
The FDA previously approved Opdivo to treat patients with unresectable (cannot be removed by surgery) or metastatic melanoma who no longer respond to other drugs.
Opdivo is marketed by Princeton, New Jersey-based Bristol-Myers Squibb.

Novartis obtains European approval for Cosentyx to treat psoriasis
Swiss drug-maker Novartis has received approval from the European Commission (EC) for its Cosentyx (secukinumab, formerly known as AIN457) to treat moderate-to-severe plaque psoriasis in adults who are candidates for systemic therapy.SEE
Secukinumab is a human monoclonal antibody designed for the treatments of uveitis, rheumatoid arthritis, ankylosing spondylitis, and psoriasis. It targets member A from the cytokine family of interleukin 17. At present, Novartis Pharma AG, the drug’s developer, plans to market it under the trade name “Cosentyx.”  It is highly specific to the human immunoglobulin G1k (IgG1k) subclass.
In July 2014 secukinumab established superiority to placebo and to etanercept for the treatment of chronic plaque psoriasis in Phase III clinical trials. In October 2014, the FDA Dermatologic and Ophthalmic Drugs Advisory Committee unanimously voted to recommend the drug for FDA approval, although this vote in and of itself does not constitute an approval. However, the FDA typically follows recommendations from these committees. In October 2014, Novartis announced that the drug had achieved a primary clinical endpoint in two phase III clinical trials for ankylosing spondylitis. As of 28 October, the relevant FDA committee had not yet responded to these results. In early November 2014, Novartis also released the results of a Phase 3 study on Psoriatic Arthritis that yielded very promising results.
Although the drug was originally intended to treat rheumatoid arthritis, phase II clinical trials for this condition yielded disappointing results. Similarly, while patients in a phase II clinical trial for [psoriatic arthritis] did show improvement over placebo, the improvement did not meet adequate endpoints and Novartis is considering whether to do more research for this condition. Novartis has said that it is targeting approval and release in early 2015 for plaque psoriasis and ankyloding spondylitis indications.

FDA Approves Blincyto (blinatumomab) for Precursor B-Cell Acute Lymphoblastic Leukemia
December 3, 2014 — The U.S. Food and Drug Administration today
approved Blincyto (blinatumomab) to treat patients with Philadelphia
chromosome-negative precursor B-cell acute lymphoblastic leukemia
(B-cell ALL), an uncommon form of ALL.
Blinatumomab (AMG103) is a drug that has anti-cancer properties. It belongs to a new class of constructed monoclonal antibodies,bi-specific T-cell engagers (BiTEs), that exert action selectively and direct the human immune system to act against tumor cells. Blinatumomab specifically targets the CD19 antigen present on B cells.
The drug was developed by a German-American company Micromet, Inc. in cooperation with Lonza; Micromet was later purchases by Amgen, which has furthered the drug’s clinical trials. In July 2014, the FDA granted breakthrough therapy status to blinatumomab for the treatment of acute lymphoblastic leukemia (ALL). In October 2014, Amgen’s Biologics License Application for blinatumomab was granted priority review designation by the FDA, thus establishing a deadline of May 19, 2015 for completion of the FDA review process.
Structure and mechanism of action
Blinatumomab enables a patient’s T cells to recognize malignant B cells. A molecule of blinatumomab combines two binding sites: a CD3site for T cells and a CD19 site for the target B cells. CD3 is part of the T cell receptor. The drug works by linking these two cell types andactivating the T cell to exert cytotoxic activity on the target cell. CD3 and CD19 are expressed in both pediatric and adult patients, making blinatumomab a potential therapeutic option for both pediatric and adult populations.
In a phase 1 clinical study with blinatumomab, patients with non-Hodgkin’s lymphoma showed tumor regression, and in some cases complete remission. There are ongoing phase 1 and phase 2 clinical trials of blinatumomab in patients with acute lymphoblastic leukemia (ALL). One phase II trial for ALL reported good results in 2010 and another is starting.
Common side effects observed in Phase 2 trials are listed below; they were temporary and typically occurred during the first treatment cycle:
- Flu-like symptoms (i.e. fever, headache, and fatigue)
- Weight increase
- Decrease of blood immunoglobulin
CNS effects were also observed during clinical trials and were treated via a lower dose of blinatumomab, administration of dexamethasone, or treatment discontinuation. Because the side effects were reversible, early monitoring for the CNS symptoms listed below is important:

Glenmark’s Enrollment Begins of First Patient in Phase II Vatelizumab (GBR 500) Trial in Relapsing Remitting Multiple Sclerosis
Enrollment Begins of First Patient in Phase II Vatelizumab Trial in Relapsing Remitting Multiple Sclerosis
Glenmark outlicensed Vatelizumab (GBR 500) to Sanofi for all indications in 2011
Mumbai – India, November 4, 2014: Glenmark announced today enrollment of the first patient in a multicenter Phase II clinical trial to evaluate Genzyme’s investigational infusion therapy vatelizumab in patients with relapsing remitting multiple sclerosis (RRMS). The trial, called EMPIRE, is designed to assess the efficacy of vatelizumab vs. placebo in RRMS patients. The safety, tolerability and pharmacokinetics of vatelizumab will also be assessed.
The mechanism of action of vatelizumab, which is developed in a collaboration between Glenmark Pharmaceuticals and Genzyme, is not yet fully understood. However, the researchers believe that it will be able to block VLA-2 on activated immune cells, which may enable the interference with collagen-binding in areas of inflammation, as well as leading to the reduction of inflammatory cascade associated with MS.
“We are excited about the commencement of this trial and are pleased with the continued progress of our partnership with Sanofi/Genzyme,” said the President of Biologics and Chief Scientific Officer of Glenmark Pharmaceuticals Ltd., Michael Buschle. EMPIRE, which will be conducted for 12 weeks, is a global phase 2a/2b double-blind, randomized, placebo-controlled study that will study the efficacy, safety, and dose-response of vatelizumab in 168 patients with active RRMS at55 sites in ten different countries.
