New data from pivotal study showed Roche’s Gazyva/Gazyvaro induced deep remissions and provided meaningful quality of life improvements in people with difficult-to-treat indolent non-Hodgkin lymphoma

On December 7, 2015 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported follow-up results from the pivotal phase III GADOLIN study in people with indolent non-Hodgkin lymphoma (iNHL) who relapsed during or within six months after treatment with a MabThera/Rituxan (rituximab)-based regimen (Press release, Hoffmann-La Roche , DEC 7, 2015, View Source [SID:1234508440]). In a subgroup analysis of people with follicular lymphoma, the most common type of iNHL, treatment with Gazyva/Gazyvaro (obinutuzumab) plus bendamustine provided significantly greater depth of remission at end of induction compared to bendamustine alone, as measured by minimal residual disease (MRD)-negativity (82% vs 43%, respectively; p<0.0001)1. MRD assessment was an exploratory analysis.

"Building on the significant progression-free survival benefit previously reported in the GADOLIN study, these follow-up data show that Gazyva/Gazyvaro-based treatment achieves significant rates of deep remission, known as minimal residual disease negativity, at the end of induction treatment," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "This achievement is particularly impressive in this difficult-to-treat patient population with follicular lymphoma, for whom treatment options are limited."

An additional analysis of the overall study population in the GADOLIN trial showed that a greater proportion of patients in the Gazyva/Gazyvaro arm reported a meaningful improvement in health-related quality of life (HRQoL) compared to those treated with bendamustine alone. HRQoL was a secondary endpoint in the study. This finding suggests that increased progression-free survival (PFS) does not appear to come at the expense of an increase in treatment-related toxicity that adversely impacts a patient’s quality of life.

Data from the GADOLIN MRD subgroup analysis will be presented in a poster session today, Monday December 7 by Dr. Kirsten Mundt, Senior Scientist, Roche at the 57th American Society of Hematology (ASH) (Free ASH Whitepaper), in Orlando, Florida. Data from the GADOLIN HRQoL analysis was also presented on Saturday, December 5, during a poster session by Dr. Peter Trask, Principal Scientist, Genentech and Professor Bruce Cheson from the Georgetown University Hospital, Washington DC, USA.

The FDA has accepted for priority review a supplemental Biologics License Application (sBLA) for Gazyva/Gazyvaro in the treatment of people with follicular lymphoma who relapsed after or are refractory to a MabThera/Rituxan-containing regimen. Marketing applications have also been submitted to other global regulatory authorities, including the EMA, for approval consideration in the treatment of people with follicular lymphoma who did not respond or who progressed during or up to six months after treatment with MabThera/Rituxan or a MabThera/Rituxan-containing regimen.

About the GADOLIN study
GADOLIN is a phase III open-label, multicentre, randomised two-arm study evaluating Gazyva/Gazyvaro plus bendamustine followed by Gazyva/Gazyvaro alone for up to two years, compared to bendamustine alone. GADOLIN included 413 patients with iNHL whose disease progressed during or within six months of prior MabThera/Rituxan-based therapy. The primary endpoint of the study is progression-free survival (PFS) as assessed by an independent review committee (IRC), with secondary endpoints including PFS as assessed by investigator review, response rate (RR), best response and overall survival (OS). GADOLIN data presented at the annual meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) in June this year showed the median PFS (mPFS) was not reached in the Gazyva/Gazyvaro-based treatment group versus 14.9 months with bendamustine alone (HR=0.55, p=0.0001) as assessed by IRC. The median PFS with Gazyva/Gazyvaro-based treatment was more than double that with bendamustine alone (29.2 months versus 14.0 months (HR=0.52, p<0.0001) as assessed by investigator review. No unexpected safety signals were identified in the Gazyva/Gazyvaro-based treatment arm. Grade 3-4 adverse events that occurred in at least two percent of patients in the Gazyva/Gazyvaro-treated group or bendamustine alone group included low white blood cell count (33% versus 26.3%), low blood platelet count (10.8% versus 16.2%), infusion-related reactions (10.8% versus 5.6%), low red blood cell count (7.7% versus 10.1%), low white blood cell count with fever (4.6% versus 3.5%), nausea (1% versus 3%), fatigue (1.5% versus 2.5%), diarrhoea (1% versus 2.5%), vomiting (2.1% versus 1%), respectively.

The MRD data from the subgroup analysis of people with follicular lymphoma will be presented at a poster presentation today, Monday 7 December, from 6:00-8:00 PM ET [Abstract #3978].

About Gazyva/Gazyvaro (obinutuzumab)
Gazyva/Gazyvaro is an engineered monoclonal antibody designed to attach to CD20, a protein found only on B-cells. Gazyva/Gazyvaro is designed to attack and destroy targeted B-cells both directly and together with the body’s immune system. Gazyva/Gazyvaro is currently approved in more than 60 countries in combination with chlorambucil, for people with previously untreated chronic lymphocytic leukaemia. The approval was based on the CLL11 study, showing significant improvements with Gazyva/Gazyvaro plus chlorambucil across multiple clinical endpoints, including PFS, overall response rate (ORR), complete response rate (CR), and minimal residual disease (MRD) when compared head-to-head with MabThera/Rituxan plus chlorambucil. Gazyva is marketed as Gazyvaro in the EU and Switzerland.

Gazyva/Gazyvaro is being studied in a large clinical programme, including the Phase III GOYA and GALLIUM studies. GOYA is comparing Gazyva/Gazyvaro head-to-head with MabThera/Rituxan plus CHOP chemotherapy in first line diffuse large B-cell lymphoma (DLBCL) and GALLIUM is comparing Gazyva/Gazyvaro plus chemotherapy followed by Gazyva/Gazyvaro maintenance head-to-head with MabThera/Rituxan plus chemotherapy followed by MabThera/Rituxan maintenance in first line indolent non-Hodgkin Lymphoma (iNHL). Additional combination studies investigating Gazyva/Gazyvaro with other approved or investigational medicines, including cancer immunotherapies and small molecule inhibitors, are planned or underway across a range of blood cancers.

About non-Hodgkin lymphoma
There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma (NHL). NHL represents approximately 85 percent of all lymphomas diagnosed2. Approximately 200,000 people die each year from NHL worldwide and approximately one person is newly diagnosed every 90 seconds2. There are more than 60 different types of NHL that fall under two subsets, aggressive and indolent (slow growing). The most common type of indolent NHL is follicular lymphoma (FL), found in about 25 percent of all NHL patients3. Most cases of NHL start in B-lymphocytes, cells that are part of the body’s immune system and help to defend the body against infections. B-cell lymphoma develops when these cells become cancerous and begin to multiply and collect in the lymphatic system such as in lymph nodes, lymphatic tissues or the spleen.

Nemucore Medical Innovations options clinical-stage Aurora Kinase Inhibitor GSK1070916 from CRT

On December 7, 2015 Nemucore Medical Innovations, Inc., a privately held, clinical-stage biopharmaceutical company dedicated to the development of therapies targeting multi-drug resistant cancers with a special emphasis on highly lethal women’s cancers, reported the completion of an option agreement with Cancer Research Technology Ltd (CRT), the commercial arm of Cancer Research UK, for the exclusive license of worldwide commercial rights to GSK1070916 (now designated NMI-900 by Nemucore), a potent Aurora B/C kinase inhibitor targeting a broad range of cancers (Press release, Cancer Research Technology, DEC 7, 2015, View Source [SID1234523201]).

"We are thrilled to be able to build on the excellent foundational clinical research conducted by Cancer Research UK, and continue the development of this innovative and very promising anticancer therapeutic," said Timothy P. Coleman, Ph.D., Chairman, Chief Executive Officer and President of Nemucore. "Based on its unique properties and pharmaceutical profile, we believe NMI-900 has best-in-class potential as a breakout therapy for treating women’s and other cancers associated with high mortality rates that have already been demonstrated to be intractable to conventional therapeutics."

NMI-900 is a potent ATP-competitive inhibitor of Aurora B kinase that has demonstrated high affinity for Aurora B, a significantly slower dissociation rate compared to its peers, potent anti-proliferative activity in multiple cancer cell lines, and minimal effects on non-proliferating normal human cells. In 2014, Cancer Research UK’s Centre for Drug Development successfully completed a Phase 1/2a trial of NMI-900. In this trial, NMI-900 elicited response in 61% of patients with no remaining standard therapies available to them across a wide variety of advanced and/or metastatic solid tumors. NMI-900 was well tolerated, with the most prevalent adverse event presenting as predictable and treatable neutropenia. NMI-900 was developed by Cancer Research UK’s Centre for Drug Development in partnership with GSK, under the Clinical Development Partnerships (CDP) initiative. This initiative, a joint effort launched by Cancer Research UK and Cancer Research Technology Ltd, provides a simple route for companies to progress oncology agents that would not otherwise be developed, and increase the number of clinical trials being undertaken for the treatment of cancer.

Dr. Keith Blundy, CEO of Cancer Research Technology commented, "We’re very pleased that Nemucore plans to take this promising new drug candidate and develop it through more clinical trials so that it has a greater chance of reaching patients who are in urgent need of new treatment options, sooner. The drug forms part of our Clinical Development Partnerships initiative, and is one of twelve drugs on the scheme that are moving out of the lab into clinical trials – something that wouldn’t have been possible otherwise."

Nemucore expects to initiate a Phase 2b clinical trial of NMI-900 in patients with advanced, platinum-resistant ovarian cancer in mid-2016 based on the supportive preclinical and early clinical trial results. As part of their clinical development and commercial strategy, the Company is concurrently developing a companion diagnostic with the Medical Prognosis Institute to identify patients most likely to respond to NMI-900. Nemucore expects to investigate the efficacy of NMI-900 in the treatment of EGF receptor-positive non-small cell lung cancer (NSCLC), myelodysplastic syndrome (MDS) and other difficult-to-treat cancers in the future.

SQZ BIOTECH ANNOUNCES PARTNERSHIP TO FIGHT CANCER WITH NOVEL CELL ENGINEERING TECHNOLOGY

On December 7, 2015 SQZ Biotech (SQZ) reported a partnership with Roche to develop a cell therapy platform that would empower a patient’s own immune cells to fight a broad range of cancers. The deal leverages SQZ’s pioneering technology to engineer B cells as a therapeutic platform for oncology – a novel approach with the potential to overcome many of the shortcomings of current cell-based therapies (Press release, SQZ Biotech, DEC 7, 2015, View Source [SID:1234508485].

The agreement provides for over $500M in upfront and potential clinical, regulatory and sales milestone-based payments for advancement of all products across all planned indications, in addition to royalties on potential future products.

"The therapeutic potential of SQZ technology builds on our ground breaking ability to engineer cell function through intracellular delivery – a long standing challenge in immunology," said Dr. Armon Sharei, Founder and Chief Executive Officer of SQZ. "In collaboration with the renowned team at Roche, we seek to engineer a patient’s own immune system to target tumors more effectively and bring hope to people suffering from cancer."

The proposed therapy involves using SQZ technology to introduce proteins into a patient’s Bcells which will then help activate killer T-cells to attack the cancer. The ability to engineer such a response is fundamentally dependent on effective delivery of tumor-associated proteins, or antigens, into the patient’s B cells. This delivery process is uniquely enabled by SQZ’s technology and harnesses the power of the patient’s own immune system to fight tumors more effectively across a broad range of cancer types.

Executive Chair of the SQZ Board Amy Schulman noted, "We are excited about this partnership because it capitalizes on the unique scientific platform that SQZ provides to engineer immune cell function. This is an important first step towards a new generation of cell based therapies." SQZ Biotech also announced the addition of two new board members: Dr. Mark Murcko, a key contributor to seven marketed drugs and the former CTO and SAB Chair of Vertex, and Garry Nicholson, President and Chief Executive Officer of XTuit Pharmaceuticals, Inc., a biopharmaceutical company developing novel micro-environment activated therapeutics and prior head of Pfizer’s global cancer business. Professor Arlene Sharpe, leader of the Dana- Farber Cancer Immunology Program and co-inventor of the first anti-PD-1 therapy, will join the

SQZ Scientific Advisory Board which already comprises a number of thought leaders including professors: Darrell Irvine (MIT), Tyler Jacks (MIT), Christopher Love (MIT), and Ulrich von Andrian (Harvard).

"We welcome the outstanding minds that are joining our efforts," added Schulman. "Mark, Garry and Arlene bring a host of scientific and business experience that will help us with a very exciting period of development and commercialization. We are also proud of Armon, an exceptional young leader, and the entire SQZ team as they work together on what promises to be an exciting journey."

Novartis highlights new CTL019 Phase II data demonstrating 93% complete remission in pediatric patients with r/r ALL

On December 7, 2015 Novartis reported that the latest findings from an ongoing Phase II study of CTL019, an investigational chimeric antigen receptor T cell (CART) therapy, further support its potential in the treatment of children and young adults with relapsed/refractory acute lymphoblastic leukemia (r/r ALL) (Press release, Novartis, DEC 7, 2015, View Source [SID:1234508479]).

The study found that 55 of 59 patients (93%) experienced complete remissions (CR) with CTL019. These results will be presented in an oral session at the 57th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting on Monday, December 7 (Abstract #681, 3:15 p.m.)[1].

In the study, median follow up was 12 months, overall survival was 79% at 12 months (95% CI, 69-91%) and relapse-free survival was 76% at six months (95% CI, 65-89%) and 55% at 12 months (95% CI, 42-73%). Results found that 18 patients had ongoing CR after 12 months of therapy[1].

"This clinical trial of CTL019 is the largest study of a CART therapy in pediatric patients with relapsed or refractory acute lymphoblastic leukemia, and it is helping us better understand the therapy’s potential to achieve durable responses in this patient population," said lead investigator Stephan Grupp, MD, PhD, the Yetta Deitch Novotny Professor of Pediatrics at the Perelman School of Medicine at the University of Pennsylvania (Penn), and director of Translational Research in the Center for Childhood Cancer Research at the Children’s Hospital of Philadelphia (CHOP). The ongoing study of CTL019 in pediatric patients with r/r ALL is being led by Dr. Grupp at CHOP and is sponsored by Penn.

Additionally, 52 of 59 (88%) patients developed Grade 1-4 cytokine release syndrome (CRS). CRS may occur after CTL019 infusion when the engineered cells become activated and multiply in the patient’s body. During CRS, patients typically experience varying degrees of flu-like symptoms with high fevers, nausea, muscle pain, and in some cases, low blood pressure and breathing difficulties. Treatment for CRS was required for hemodynamic or respiratory instability in 27% of patients and was reversed in all cases with an IL-6 receptor antagonist[1].

"We have observed pediatric patients in this study achieve complete remissions with CTL019 treatment, in many cases without stem cell transplantation, which underscores the potential for CTL019 to fill an unmet medical need," said Usman Azam, MD, Global Head, Cell & Gene Therapies Unit, Novartis Pharmaceuticals. "These new longer-term data add to the growing understanding of CTL019 for patients with relapsed or refractory acute lymphoblastic leukemia who run out of treatment options."

Novartis recently expanded its own global multisite Phase II clinical trial of CTL019 in pediatric r/r ALL with the opening of study sites in Europe, Canada and Australia. A list of participating trial centers is available at View Source (link is external).

Novartis and Penn have an exclusive global collaboration to research, develop and commercialize CART therapies for the investigational treatment of cancers. In July 2014, the FDA designated CTL019 as a Breakthrough Therapy for the treatment of pediatric and adult patients with r/r ALL under the Penn Investigational New Drug application (IND). Breakthrough Therapy designation is intended to expedite the development and review of drugs that treat serious or life-threatening conditions if the therapy has demonstrated substantial improvement over an available therapy on at least one clinically significant endpoint. Novartis holds the worldwide rights to CARs developed through the collaboration with Penn for all cancer indications, including the lead program, CTL019.

Additional key CART data presented at ASH (Free ASH Whitepaper) include:

Findings from a study on treatment with CTL019 in children with r/r ALL that face additional central nervous system (CNS) relapse complications (Abstract #3769, December 7, 6-8 p.m.)[2]

Data on characterization and accurate early prediction of CRS in r/r ALL patients treated with CTL019 (Abstract #1334, December 5, 5:30 p.m.)[3]

Preliminary efficacy and safety data on humanized CTL119 in children with r/r ALL (Abstract #683, December 7, 3:45 p.m.)[4]
Preclinical data from a study on CART123 to mitigate toxicity in acute myeloid leukemia (Abstract #565, December 7, 10:30 a.m.)[5]

Because CTL019 is an investigational therapy, the safety and efficacy profile has not yet been established. Access to investigational therapies is available only through carefully controlled and monitored clinical trials. These trials are designed to better understand the potential benefits and risks of the therapy. Because of uncertainty of clinical trials, there is no guarantee that CTL019 will ever be commercially available anywhere in the world.

Juno’s Investigational CAR T Cell Product Candidates JCAR015 and JCAR014 Demonstrate Encouraging Clinical Responses in Patients with B-cell Cancers

On December 7, 2015 Juno Therapeutics, Inc. (NASDAQ: JUNO), a biopharmaceutical company focused on re-engaging the body’s immune system to revolutionize the treatment of cancer, reported, in partnership with its collaborators, that clinical data from separate trials for chimeric antigen receptor (CAR) T cell product candidates, JCAR015 and JCAR014, demonstrated encouraging clinical responses in patients with relapsed or refractory (r/r) acute lymphoblastic leukemia (ALL) (Press release, Juno, DEC 7, 2015, View Source [SID:1234508478]).

JCAR015 and JCAR014 results will be presented in oral and poster presentations, respectively, today at the 57th Annual Meeting of the American Society of Hematology (ASH) (Free ASH Whitepaper) in Orlando.

"We are encouraged by the continued positive results of JCAR015 in adult patients with r/r ALL. We look forward to advancing this product candidate in its ongoing pivotal Phase II trial, with the goal of potentially making it broadly available to patients," said Mark Frohlich, M.D., Executive Vice President, Development and Portfolio Strategy. "The JCAR014 data presented show the addition of fludarabine to cyclophosphamide-based lymphodepletion improves CAR T cell expansion, persistence, and disease-free survival in r/r B-cell adult ALL patients treated with a defined cell product. The continued translational insights from this ongoing trial also demonstrate the importance of depth of response in order to maintain a durable response."

In an oral presentation on Monday, December 7, 2015, Jae H. Park, M.D. of Memorial Sloan Kettering Cancer Center will present, "Implications of Minimal Residual Disease Negative Complete Remission (MRD-CR) and Allogeneic Stem Cell Transplant on Safety and Clinical Outcome of CD19-Targeted 19-28z CAR Modified T Cells in Adult Patients with Relapsed, Refractory B-Cell ALL." Dr. Park will provide updated results on a total of 46 patients treated with JCAR015 in B-cell ALL. Key takeaways include:

Overall complete response (CR) was reported in 37/45 (82%) evaluable patients and minimal residual disease (MRD)-negative CR was reported in 30/36 (83%) patients who achieved a CR and were evaluable for MRD analysis.

r/r B-cell ALL patients who achieve MRD-negative CR have improved survival compared to those who achieve MRD-positive CR.
r/r B-cell ALL patients who achieve MRD-negative CR appear to have comparable survival whether or not they proceed to an allogeneic stem cell transplant.

JCAR015 has consistent efficacy across multiple high risk subgroups, including elderly and multiple relapsed patients.
Severe cytokine release syndrome (CRS) was observed in 11/46 (24%) patients. Severity of CRS correlated with disease burden and was generally reversible.

Grade 3/4 neurotoxicity was observed in 13/46 (28%) patients. As previously disclosed, Grade 5 toxicity was observed in 3/46 (6%) patients, and was assessed to be unrelated to JCAR015 treatment in one of these patients.

In a poster presentation on Monday, December 7, 2015, Cameron J. Turtle, MBBS, Ph.D. of the Fred Hutchinson Cancer Research Center will present, "Addition of Fludarabine to Cyclophosphamide Lymphodepletion Improves In Vivo Expansion of CD19 Chimeric Antigen Receptor-Modified T Cells and Clinical Outcome in Adults with B-Cell Acute Lymphoblastic Leukemia." Dr. Turtle will provide updated results on a total of 30 patients treated with JCAR014 against r/r B-cell ALL. Key takeaways include:

The addition of fludarabine to cyclophosphamide-based lymphodepletion to a defined cell product improves CAR T cell expansion, persistence, response rate, and disease-free survival in r/r B-cell adult ALL.

The CR rate as documented by flow cytometry was 27/29 (93%) of evaluable patients with r/r B-cell ALL. After the addition of fludarabine, 17/17 (100%) of patients had a CR and a complete molecular remission (CMR) rate, as measured by flow cytometry.
Severe CRS was reported in 7/30 (23%) and Grade ≥3 neurotoxicity was noted in 15/30 (50%) ALL patients.
The risk-stratified dosing of JCAR014 is potent, feasible, and reduced the incidence of severe CRS.

About Juno’s Chimeric Antigen Receptor (CAR) and T Cell Receptor (TCR) Technologies
Juno’s chimeric antigen receptor (CAR) and T cell receptor technologies (TCR) genetically engineer T cells to recognize and kill cancer cells. Juno’s CAR T cell technology inserts a gene for a particular CAR into the T cell, enabling it to recognize cancer cells based on the expression of a specific protein located on the cell surface. Juno’s TCR technology provides the T cells with a specific T cell receptor to recognize protein fragments derived from either the surface or inside the cell. When either type of engineered T cell engages the target protein on the cancer cell, it initiates a cell-killing response against the cancer cell. JCAR014 and JCAR015 are investigational product candidates and their safety and efficacy have not been established.
