On April 8, 2014 Janssen Research & Development reported the submission of a supplemental New Drug Application (sNDA) for IMBRUVICA (ibrutinib) to the U.S. Food and Drug Administration (FDA) by its collaboration partner Pharmacyclics, Inc (Press release Johnson & Johnson, APR 8, 2014, View Source [SID:1234500380]). This regulatory submission is based on data from the Phase 3 RESONATE study in relapsed or refractory chronic lymphocytic leukemia (CLL). IMBRUVICA is being jointly developed and commercialized by Janssen and Pharmacyclics.
In February 2014, IMBRUVICA received FDA approval to treat patients with CLL who have received at least one prior therapy. This indication is based on an overall response rate (ORR) from Phase 2 data and an improvement in survival or disease-related symptoms has not been established. The current approval was granted under the FDA’s Accelerated Approval regulations and required the completion of an additional, larger Phase 3 trial to verify clinical benefit.
The Phase 3 PCYC-1112 (RESONATE) study is a randomized, multi-center, open-label study, which compares once-daily oral IMBRUVICA versus intravenous ofatumumab in 391 patients with CLL or small lymphocytic lymphoma (SLL), who had received at least one prior therapy. The RESONATE trial was halted early in January 2014 based on the recommendation of an Independent Data Monitoring Committee (IDMC) at the formal pre-planned interim analysis, which found IMBRUVICA was associated with a significant improvement in progression-free survival (the primary endpoint of the study) versus ofatumumab, and in overall survival (a key secondary endpoint of the trial). Data from this study were accepted and will be presented at the upcoming 50th annual meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper).
Ambit Announces Initiation Of Quizartinib QUANTUM-R Phase 3 Trial
On April 8, 2014 Ambit Biosciences reported the initiation of the QUANTUM-R Phase 3 clinical trial (NCT02039726) comparing quizartinib as monotherapy to chemotherapy regimens in relapsed/refractory acute myeloid leukemia (AML) patients with the FMS-like tyrosine kinase-3 (FLT3)-ITD mutation (Press release Ambit Biosciences, APR 8, 2014, View Source [SID:1234500376]).
The trial will be conducted in FLT3-ITD positive AML patients over the age of 18 who have relapsed from, or are refractory to, frontline chemotherapy, including those patients relapsing following hematopoietic stem cell transplantation (HSCT). Patients will be dosed continually until disease progression or intolerable toxicity. Patients who proceed to HSCT after quizartinib treatment will be able to reinitiate treatment with quizartinib following the transplant.
The trial is expected to enroll approximately 326 patients in the United States, Western Europe, Canada and Australia. The primary endpoint for the Phase 3 clinical trial will be overall survival. An interim analysis will be conducted and will include an adaptive design component that will allow the Data Safety Monitoring Board (DSMB) to increase the number of patients, if warranted. Enrollment is expected to be completed in the second half of 2015, assuming there is no increase in the number of patients following the interim analysis.
The Phase 3 trial follows completion of the Phase 2 and Phase 2b clinical trials, which demonstrated the key clinical benefits of quizartinib as a monotherapy, including a high response rate in relapsed/refractory FLT3-ITD positive patients; a substantial number of patients who were bridged to a potentially curative HSCT; and median overall survival in FLT3-ITD positive patients which compared favorably to historical survival data reported for FLT3-ITD positive and negative AML patients. Results from these studies were presented at medical conferences in 2012 and 2013.

Roche and Oryzon announce collaboration to develop epigenetics-based medicines
On April 7, 2014 Roche and Oryzon Genomics reported they have entered into a worldwide collaboration to research, develop and commercialize inhibitors of Lysine Specific Demethylase-1 (LSD1; KDM1A), an epigenetic modulator that regulates gene expression (Press release Oryzon, APR 7, 2014, View Source [SID:1234500879]).
The lead molecule, ORY-1001, was granted orphan drug status by EMA in August 2013 and is currently in phase I/IIA for acute myeloid leukaemia (AML). Roche will have sole responsibility for developing and commercializing ORY-1001 and/or its backup compounds. The agreement includes the licensing of two patent families that Oryzon has created in its pioneering research in LSD1, and includes options for other Oryzon programs to be incorporated in future. The agreement also includes an initial two-year collaborative research program between Oryzon and Roche’s New York-based Translational Clinical Research Center (TCRC), Roche’s hub for research and early development activities in North America, to better understand the potential of LSD1 inhibitors in oncology and haematology.
John Reed, Roche’s Head of Pharma Research and Early Development, commented, "Oryzon is working at the leading edge of LSD1 inhibition, a technology with great potential to bring genuine patient benefit. Our TCRC in New York has been launched with a mandate to identify partnerships that drive innovation, providing an industryleading conduit between sources of breakthrough science and the broader Roche organization. This collaboration on LSD1 inhibition with Oryzon fulfils that mandate perfectly."
Carlos Buesa, CEO of Oryzon, added, "We are excited to work with Roche in developing ORY-1001 to make a significant difference for patients with AML and, hopefully, for patients in other disease areas as well. Roche is the global leader in oncology and haematology, with a tremendous expertise in clinical development; this was the primary reason to prioritize this alliance. The collaboration is recognition of our cutting-edge science and our experience in epigenetics, an approach that we believe holds great promise for many patient groups."
Under the terms of the agreement, Oryzon will receive an upfront payment and near-term milestones totalling $21 million, plus potential development, commercial and sales milestone payments across haematology, cancer and non-malignant indications that could exceed $500 million, together with tiered royalties on sales which range up to mid-double digits.
