Array planning for potential return of MEK inhibitor

BOULDER, Colo. , Aug. 12, 2014 /PRNewswire/ -- Array BioPharma Inc. (NASDAQ: ARRY) today reported results for the fourth quarter and full year of its fiscal year ending June 30, 2014 .

Ron Squarer, Chief Executive Officer of Array, noted, "The Array-invented MEK inhibitors, binimetinib and selumetinib, are currently enrolling six Phase 3 trials, and each of our partners has announced expectations for regulatory filings next year.  In addition, we continue to advance our wholly-owned filanesib program, which has the potential to be an important novel treatment for patients with multiple myeloma.  Given the progress on our key programs and the possible return of binimetinib to Array, we are looking forward to an exciting year." 

Revenue for the fourth quarter of fiscal 2014 was $6.0 million , compared to $25.4 million for the same period in fiscal 2013.  The prior year period benefited from the recognition of a $10.0 million upfront payment from Oncothyreon, as well as the recognition of a majority of the $5.0 million milestone earned from Novartis for the start of a Phase 3 trial.  Additionally, current quarter revenue decreased due to the recognition of all remaining revenue under our original arrangement with Celgene during the fourth quarter of fiscal 2013 and the recognition of all remaining revenue in April 2014 related to the original upfront and milestone payments to date from Novartis for the binimetinib collaboration.  Cost of partnered programs was $11.4 million , compared to $7.0 million in the same period last year.  This increased cost is related to the new and expanded collaborations with Biogen Idec and Loxo Oncology during the quarter, both of which generate ongoing research funding. In addition, the cost of binimetinib co-development with Novartis increased as the drug has advanced into three Phase 3 clinical trials.  Net loss for the fourth quarter was $28.2 million , or ($0.22) per share, compared to a net loss of $17.7 million , or ($0.15) per share, for the same period in fiscal 2013.  Array ended the quarter with $112 million in cash, cash equivalents and marketable securities.

Array reported revenue of $42.1 million for the fiscal year ended June 30, 2014 , compared to revenue of $69 .6  million for fiscal 2013, mostly driven by the quarter over quarter dynamics described above.  Cost of partnered programs was $46.0 million , compared to $30.1 million in the same period last year.  Net loss for the fiscal year ended June 30, 2014 was $85.3 million , or ($0.69) per share, compared to a net loss of $61.9 million , or ($0.57) per share, reported in fiscal 2013.  

KEY PIPELINE UPDATES Binimetinib (MEK162) (co-developing with Novartis) - Array planning for potential return of binimetinib, three Phase 3 trials enrolling and clinical data presented at ASCO In 2010, Array entered into an agreement with Novartis under which Novartis received worldwide rights to binimetinib.  In April 2014 , Novartis and GlaxoSmithKline (GSK) announced a definitive agreement which included Novartis acquiring GSK's MEK inhibitor, Mekinist®.  The transaction is subject to approval by GSK shareholders and closing conditions, including anti-trust approvals.  If Novartis' binimetinib development and commercialization rights are returned to Array, Novartis must provide support for ongoing clinical studies as specified in our agreement. 

Three Phase 3 trials with binimetinib in advanced cancer patients continue to enroll: NRAS-mutant melanoma (NEMO / NCT01763164), low-grade serous ovarian cancer (MILO / NCT01849874) and BRAF-mutant melanoma (COLUMBUS / NCT01909453).  NRAS-mutant melanoma represents the first potential indication for binimetinib, with a Novartis projected regulatory filing estimated in 2015.  Array reported previously that Novartis has indicated it will continue to honor its obligations under the Array-Novartis agreement relating to binimetinib, including obligations relating to support for ongoing clinical trials.

Binimetinib was featured at the 2014 American Society for Clinical Oncologists (ASCO) annual meeting in June.  At the meeting, preliminary data for the combination of binimetinib and CDK4/6 inhibitor LEE011 (discovered by Novartis Institutes for BioMedical Research in collaboration with Astex Pharmaceuticals) was presented.  The data from this Phase 1b/2 dose-escalation study conducted by Novartis in NRAS-mutant melanoma demonstrated an acceptable safety profile for most patients with promising preliminary antitumor activity.  Additional patients are being enrolled in the trial and the dosing schedule for the combination is being optimized.  As of March 21, 2014 , 22 patients were enrolled.  Of 21 evaluable patients, seven achieved a partial response (33%, 3 confirmed, 4 unconfirmed) and 11 had stable disease (52%).  Several patients experienced early tumor shrinkage with major symptomatic improvement; 12 patients remain on treatment (55%, duration 2 to 8 months).  Common treatment-related adverse events included elevated creatine phosphokinase (CPK) and creatinine; skin, hematologic and gastrointestinal events; edema; and fatigue.

In addition, a Phase 1b study with binimetinib and Novartis' PI3K inhibitor, BYL719, in patients with RAS- and BRAF-mutant solid tumors (over 10 tumor types) was presented, with encouraging preliminary antitumor activity in patients with ovarian cancer.  Three out of four (75%) ovarian cancer patients achieved a partial response.  In the overall study population, the most common dose-limiting toxicities and treatment'related adverse events included gastrointestinal events and rashes.  

Pipeline prioritization related to binimetinib Given the potential return of binimetinib and the investment value proposition it would represent, Array has no plans to invest internally at this time in ARRY-614, a p38/Tie2 inhibitor for myelodysplastic syndromes.  In addition, Array has no plans at this time to invest further internally in ARRY-502, a CRTh2 receptor antagonist for asthma, and will only provide an update if Array finalizes a collaboration on this program.

Selumetinib (partnered with AstraZeneca) - Three Phase 3 trials enrolling including a study in non-small cell lung cancer (NSCLC) and clinical data presented at ASCO Three Phase 3 trials continue to advance with selumetinib in advanced cancer patients:  second-line KRAS-mutant advanced or metastatic NSCLC (SELECT-1 / NCT01933932), differentiated thyroid cancer (ASTRA / NCT01843062) and metastatic uveal melanoma (SUMIT / NCT01974752).  AstraZeneca has indicated that a projected regulatory filing from the uveal melanoma study is estimated to be in 2015.  In addition, AstraZeneca recently announced two new non-small cell lung cancer studies involving selumetinib; one in combination with MEDI14736 (anti-PD-L1), the other in combination with AZD9291 (mutant-selective EGFR).

Selumetinib was featured at the 2014 ASCO annual meeting.  At the meeting, preliminary data in a Phase 1 study for selumetinib showed favorable clinical activity in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas.  Eleven of 18 patients (61%) achieved a partial response, defined as a greater than or equal to 20% improvement.  Common treatment-related adverse events included acneiform rash, asymptomatic CPK elevation, nausea, vomiting, diarrhea, abdominal pain and fatigue.  All toxicities were reversible.   

Filanesib (ARRY-520) - Progress continues with multiple myeloma (MM) development plan Filanesib is a highly selective, targeted KSP inhibitor with a mechanism of action distinct from currently-available myeloma therapies, such as immunomodulatory drugs and proteasome inhibitors.  Based on the strength of data from ongoing and completed clinical trials, along with recent discussions with the U.S. Food and Drug Administration (FDA), Array is developing filanesib in combination with the novel proteasome inhibitor Kyprolis® (carfilzomib).  Two Phase 2 trials are enrolling patients:  ARRAY-520-216 (NCT01989325), a randomized Phase 2 trial comparing Kyprolis plus filanesib versus Kyprolis alone in 75 relapsed refractory multiple myeloma (RRMM) patients, and the AfFIRM trial (NCT02092922), a global Phase 2 study with single-agent filanesib in 160 patients with RRMM.  Array is currently working towards initiating this year the FACTOR trial, a global Phase 3 study comparing Kyprolis plus filanesib to Kyprolis alone in several hundred patients with RRMM. 

ARRY-797 (ARRY-371797) - Phase 2 trial enrolling patients with LMNA-related DCM Array is enrolling a 12-patient Phase 2 study (NCT02057341) to study the effectiveness and safety of ARRY-797 in patients with LMNA-related dilated cardiomyopathy (DCM), a serious, genetic cardiovascular disease.  By age 45, approximately 70% of patients with LMNA-related DCM experience cardiovascular death, transplant or a major cardiac event. Array anticipates having preliminary results from this study by the end of the year.

Loxo Oncology / LOXO-101 - Loxo Oncology completes initial public offering On August 1, 2014 , Loxo Oncology, which is listed on the NASDAQ under the symbol LOXO, announced the pricing of its initial public offering of 5.3 million shares of its common stock at a price to the public of $13.00 per share.  Resulting from the July 2013 collaboration agreement between Array and Loxo, Array currently holds 1.6 million shares in Loxo common stock.  Array and Loxo initiated a collaboration to discover and develop small molecule drugs for novel oncology targets, including Loxo's lead program, LOXO-101, a pan-Trk inhibitor that is currently in Phase 1.  Array receives research funding from Loxo for discovery work conducted by Array scientists and, pursuant to our collaboration agreement, Array has the potential to receive milestones of up to $435 million and royalties on product sales. 

GROWING DRUG DISCOVERY COLLABORATION BUSINESS Biogen Idec - New agreement to discover and develop drugs for the treatment of autoimmune disorders Array announced a collaboration agreement with Biogen Idec for the discovery and development of inhibitors targeting a novel kinase for the treatment of autoimmune disorders.  The collaboration target and lead inhibitors were discovered through Array's proprietary Kinase-Directed Phenotypic Screening Platform.  This technology relies on Array's deep experience in kinase inhibitor chemistry and phenotypic screening, which can be applied to any disease where a desired cellular phenotype can be envisioned.  Under the terms of the agreement, Biogen and Array will collaborate on the discovery of the novel kinase inhibitors. Biogen will be responsible for all aspects of clinical development and commercialization. The agreement includes research funding for three years, various milestone payments payable upon achievement of certain development and commercial milestones, and royalties to Array.
