FDA Breakthrough Therapy Designation #57: Juno Therapeutics’ Immunotherapy For ALL

Glowing_heart_(114668824)

Juno Therapeutics, a Seattle-based clinical-stage start-up biotechnology company, is developing novel cellular immunotherapies to treat cancer. The company announces November 24th that its JCAR015 Chimeric Antigen Receptor (CAR) product candidate receives the FDA Breakthrough Therapy Designation (BTD) for treatment of relapsed/refractory B-Cell Acute Lymphoblastic Leukemia (r/r ALL).

Juno Therapeutics’ collaboration partner, Memorial Sloan Kettering Cancer Center (MSKCC) in New York, filed for the FDA BTD. Since the creation of Juno Therapeutics in December 2013, the start-up company raises more than $300 million.

Just a week ago, FDA Orphan Drug Designation (ODD) was given to JCAR015 and the company also filed an Initial Public Offering (IPO) for its public stock.  All 3 of Juno Therapeutics CAR T-cell product candidates that are currently in clinical trials are based on CAR technology that “employs the body’s immune system to attack cancer cells”. The following are Juno Therapeutics CAR T-cell product candidates :

•   JCAR014 for refractory Chronic Lymphocytic Leukemia (CLL), non-Hodgkin’s Lymphoma (NHL), & ALL (Fred Hutchinson Cancer Research Center, Seattle)

•   JCAR015 for r/r ALL (MSKCC)

•   JCAR017 for r/r CD19-positive pediatric leukemia (Seattle Children’s Hospital).

Juno Therapeutics will present data on these clinical trials at the 54th Annual Meeting of the American Society of Hematology (ASH) next week in San Francisco.

In July 2014, the FDA gives Novartis’ CAR T-cell therapy a Breakthrough Therapy Designation (BTD) for its personalized cell therapy CTL019, for relapsed/refractory Acute Lymphoblastic Leukemia (r/r ALL). CTL019 also receives FDA Orphan Drug Designation (ODD) in January 2014.

Regeneron Pharmaceuticals and Sanofi announce on November 20th that the FDA grants the coveted Breakthrough Therapy Designation (BTD) to investigational therapy, Dupilumab. The FDA BTD for Dupilumab is for the treatment of adults with moderate-to-severe Atopic Dermatitis (AD), who aren’t controlled adequately with topical prescription therapy and/or for whom these treatments aren’t appropriate. The BTD is based on positive results from Phase I and II clinical trials. A global Phase III clinical program for Dupilumab is ongoing.

Moderate-to-severe AD is a serious form of eczema that is a chronic inflammatory disease. AD in patients results in pruritus, cutaneous dryness, and skin lesions marked by redness, crusting/oozing, and other symptoms.

Regeneron Pharmaceuticals, a Tarrytown, New York-based biotech company, has 3 approved products that the company sells through collaborations with other large pharmaceutical companies. This is the 2nd FDA BTD for Regeneron Pharmaceuticals:

# Drug Name Sponsor Company Indication
1 Eylea (Aflibercept) Regeneron Pharmaceuticals Diabetic Retinopathy in Patients with Diabetic Macular Edema
2 Dupilumab Regeneron Pharmaceuticals/ Sanofi Atopic Dermatitis

.

Regeneron Pharmaceuticals was in the news during the summer, when BioMarin Pharmaceutical sold its Rare Pediatric Disease Priority Review Voucher  for $67.5 million to the company and Sanofi.

Introducing 1st Rare Disease Advocacy World (RDAW) USA 2015 Meeting

RDAW launch 200x200

Patient advocacy groups are one of the most important powerful stakeholders that contribute to the success of orphan drug development and changes in policies for global regulatory agencies.

Just recently in September 2014, the European Medicines Agency (EMA) announces the launch of a pilot program to involve patients in the benefit-risk evaluation  of medicines at the regulatory agency’s Committee for Medicinal Products for Human Use (CHMP). CHMP is the EMA committee responsible for preparing the agency’s opinions on questions concerning human medicines – it conducts the initial benefit-risk analysis of medicines. In August 2014, Rona Ambrose, Canada’s Minister of Health, announces the launch of a pilot project “ … targeting patient input from Canadians with rare diseases to help inform future reviews of orphan drugs …. The Pilot Project will simulate how input from patients will be gathered and incorporated into the drug submission review process once the Orphan Drug Framework is in effect.” The FDA has started the Patient-Focused Drug Development (PFDD) initiative to obtain and better understand a patient’s perspective about their disease and to get patient feedback on treatments.

In recognition of the power, strength, passion, and compassion of patient advocacy organizations, there is a new portion of the World Orphan Drug Congress USA 2015, devoted to this trend. Rare Disease Advocacy World (RDAW) is a conference of its own which leverages the success of the world’s largest orphan drug event – The World Orphan Drug Congress USA – to grow the breadth and scope of the event even further and embrace and empower rare disease advocacy like never before. RDAW brings stakeholders together at this co-located conference. RDAW will be a 2-day event that will provide opportunities for patient advocacy groups to learn more about:

•   Achieving a scientific mindset

•   Understanding your disease

•   Characterizing your patients

•   Developing a strategic plan

•   Raising awareness and raising funds.

Several experts in the field will be hosting a series of case studies and workshops:

•   Pat Furlong, President & CEO, Parent’s Project Muscular Dystrophy (PPMD)

•   Nancy Goodman, Founder & Executive Director, Kids V Cancer

•   Eric Hoffman, Director, Research Center for Genetic Medicine, The George Washington University.

A Brochure is available for download.

Ultra-Rare Diseases: BioBlast Pharma Orphan Drug Designations

256px-Nessler_cylinders

BioBlast Pharma, a Tel Aviv, Israel-based clinical-stage biotech founded in 2012, is developing a platform of products for rare and ultra-rare genetic diseases.

I – Cabaletta For Oculopharyngeal Muscular Dystrophy (OPMD)

BioBlast Pharma’s most advanced product Cabaletta, a mutant protein stabilizing platform, is in a Phase II clinical trial (HOPEMD) for the treatment of Oculopharyngeal Muscular Dystrophy (OPMD). Cabaletta is an IV formulation of Trehalose, which the company says enables the drug to reach muscles. Trehalose prevents aggregation of proteins in cells. BioBlast Pharma receives FDA Orphan Drug Designation (ODD) in October 2013 for Cabaletta (Trehalose) for the treatment of OPMD.

OPMD is a rare genetic condition and form of muscular dystrophy that begins usually after age 40. It effects the muscles of the eyelid first, resulting usually in droopy eyelids (ptosis), followed by problems with swallowing (dysphagia). Patients with OPMD can also have weakness in the muscles near the center of the body (proximal muscles). There is currently no medical therapy that can alleviate symptoms or slow the progression of OPMD.

OPMD is caused by a genetic defect in a gene that encodes a protein called PABPN1. The mutation can be diagnosed by a molecular blood test.

II – Cabaletta For Spinocerebellar Ataxia Type 3 (SCA3)

BioBlast Pharma announces on November 19th, that Trehalose receives FDA ODD for the treatment of Spinocerebellar Ataxia Type 3 (SCA3). This is the 2nd FDA ODD for Cabaletta. A Phase II clinical trial to test the efficacy of Cabaletta in SCA3 is currently being conducted and a SCA3 pivotal study is planned to start in 2015.

SCA3 is a genetic disease where patients have memory deficits, difficulty with swallowing and speech, and other muscular disorders. SCA3 begins in early adolescence and progresses over time. It is an incurable disease with no currently approved treatment. SCA3 is caused by an expansion of a gene called ATXN3. Currently there is no treatment that is effective.

BioBlast Pharma FDA ODDs For Cabaletta

# FDA ODD Date Indication
1 10.25.13 Occulopharyngeal Muscular Dystrophy (OPMD)
2 11.17.14 Spinal Cerebellar Ataxia type 3 (SCA3 or Machado Joseph disease)

FDA Breakthrough Therapy Designation: Pfizer’s Meningococcal B Vaccine Available In US

Vaccine

 

Pfizer announces November 18th that Trumenba (Meningococcal Group B Vaccine) is now available for healthcare providers, retail pharmacies, hospitals and college health centers to order in the US. It is the first and only FDA-approved vaccine for active immunization to prevent invasive disease caused by Neisseria meningitidis serogroup B in people ages 10 – 25.

Just 3 weeks ago on October 29th, the FDA grants Accelerated Approval of Trumenba. Trumenba is reviewed and approved under the FDA’s Breakthrough Therapy Designation (BTD) and Priority Review programs. Pfizer receives the FDA BTD in March 2014. Part of the FDA Accelerated Approval process requires Pfizer to conduct further studies to verify Trumenba’s effectiveness against additional strains of N. meningitidis serogroup B.

Pfizer’s competitor for this indication in the US is Novartis’s Bexsero Vaccine that receives the FDA BTD in April 2014 Bexsero is not yet approved of in the US. In Europe, Australia, and Canada, Bexsero is already approved for Meningococcal disease caused by serogroup B.

2014 Immunotherapy Cancer Biotech Initial Public Offerings (IPOs)

256px-Wall_Street_&_Broadway

In addition to Juno Therapeutics receiving FDA Orphan Drug Designation (ODD) for its lead product candidate JCAR015 for Acute Lymphoblastic Leukemia (ALL) last week, the company files a S-1 Form with the US Securities and Exchange Commission (SEC) Commission on November 17th. The S-1 proposes an Initial Public Offering (IPO) of its common stock raising up to $150 million. The company’s listing will be under the symbol “JUNO” on the NASDAQ Global Select Market. Morgan Stanley, J.P. Morgan and Goldman Sachs & Co are underwriting the IPO.

Per the S-1 Form, as of July 2014, JCAR015’s most recent data demonstrates, in an ongoing Phase I clinical trial, an amazing 91% complete remission rate in 22 evaluable adult patients with relapsed/refractory B cell ALL. Historical complete remission rates without JCAR015 in a similar population are less than 10%. JCAR015 Phase I trials are currently underway at Juno’s collaboration partner, Memorial Sloan-Kettering Cancer Center. The company plans on starting a Phase II trial in mid-2015 exploring JCAR015 in the same population that could support accelerated US regulatory approval.

By the end of 2015, Juno Therapeutics plans to start testing for at least 3 more drug candidates.

Other biotechnology IPOs in 2014 developing cancer immunotherapies:

•   Kite Pharma (partnering with the US National Cancer Institute); Receives FDA ODD in March 2014 For Diffuse Large B-Cell Lymphoma (DLBCL) & EMA COMP positive opinion recommendation for ODD on November 17th

•   Affimed Therapeutics

•   Immune Design

•   Argos Therapeutics

•   Bellicum Pharmaceuticals (files 11/18/14 registration statement for proposed IPO with the US SEC to raise up to $115 million).
