ZEJULA is the only PARP inhibitor that has demonstrated a clinically meaningful increase in progression-free survival (PFS) in women with recurrent ovarian cancer, regardless of BRCA mutation or biomarker status, in a randomized, prospectively designed Phase 3 clinical trial. ZEJULA offers oral, once-daily dosing, enabling convenient administration for maintenance treatment. FDA approval of ZEJULA is based upon data from the international Phase 3 ENGOTOV16/NOVA trial, a double-blind, placebo-controlled study that enrolled 553 patients with recurrent ovarian cancer who had achieved either a PR or CR to their most recent platinum-based chemotherapy. Approximately two-thirds of study participants did not have germline BRCA mutations. Progression in the NOVA study was determined by robust, unbiased, blinded central review, to be the earlier of radiographic or clinical progression. ZEJULA significantly increased PFS in patients with and without germline BRCA mutations as compared to control. Treatment with ZEJULA reduced the risk of disease progression or death by 74% in patients with germline BRCA mutations (HR 0.26) and by 55% in patients without germline BRCA mutations (HR 0.45). The magnitude of benefit was similar for patients entering the trial with a PR or a CR.

The most common grade 3/4 adverse reactions to ZEJULA in the NOVA trial included thrombocytopenia (29%), anemia (25%), neutropenia (20%), and hypertension (9%). The majority of hematologic adverse events were successfully managed via dose modification, and discontinuation of therapy due to thrombocytopenia, neutropenia and anemia occurred in 3.3%, 1.9% and 1.4% of patients, respectively. Following dose adjustment based on individual tolerability, the incidence of grade 3/4 thrombocytopenia was low; approximately

"We are pleased to report that our lead clinical candidate, rigosertib, is positioned for multiple key milestones, following the advancement of our late stage trials for patients with myelodysplastic syndromes (MDS). Enrollment for the targeted INSPIRE pivotal trial for patients with second-line higher-risk (HR) MDS is on track, with trial sites currently active across 17 countries on four continents. The trial eligibility criteria are highly selective and require extensive search to identify appropriate patients meeting the stringent entry criteria. We intend to maintain current momentum, with interim analysis expected in the second half of the year and full enrollment by the first quarter of 2018," said Dr. Ramesh Kumar, President and Chief Executive Officer.

"Development of oral rigosertib in combination with azacitidine for first line HR MDS patients is advancing as planned, with the protocol for a pivotal Phase 3 trial expected to be ready for submission to FDA for a Special Protocol Assessment during the second or third quarter of this year. MDS represents a growing and underserved market, with more than 10,000 patients diagnosed with HR-MDS annually in the U.S. No new therapy has been approved in over ten years and none has ever been approved for patients after the failure of hypomethylating agents."

"We will continue to focus on our lead programs and will look for partnering or other opportunities for our other pipeline and clinical programs. We will be presenting non-clinical data on pipeline compounds at the upcoming American Association for Cancer Research (AACR) (Free AACR Whitepaper) conference," added Dr. Kumar.

Recent Business Highlights:

Enrollment on Track for INSPIRE Pivotal Trial of IV Rigosertib in 2nd line HR-MDS

The global Phase 3 INSPIRE trial of IV rigosertib in patients who have failed to respond to or progressed following hypomethylating agent (HMA) therapy is active in sites across four continents in 16 countries, which is in line with the Company’s plan. Our partner, SymBio Pharmaceuticals, has opened an additional 33 sites in Japan in collaboration on the INSPIRE protocol. The trial is expected to be active in all 19 countries in the second quarter of 2017 following the activation of sites in Switzerland and the Netherlands.
Pre-planned interim analysis for the global INSPIRE trial is currently on track and will be conducted after 88 death events have occurred.
Progress on Oral Rigosertib Combination with Azacitidine for 1st-line HR-MDS

Following a productive end of Phase 2 meeting with the Food and Drug Administration (FDA) in the third quarter of 2016, a protocol for a pivotal Phase 3 trial is being developed. The Company expects to submit this protocol for review by regulatory agencies in the US and Europe in the second or third quarter of 2017.
The pivotal trial will be designed as a 1:1 randomized placebo controlled trial of oral rigosertib plus azacitidine, compared to azacitidine plus placebo. The Company plans to use a full dose of azacitidine, as defined in the product insert. The patient population studied on this trial will be HMA naïve HR MDS patients. The primary endpoint for assessment of efficacy will be Response Rate of complete remission (CR) + partial remission (PR,) as per the International Working Group (IWG) 2006 Response criteria.
Formal FDA review will be sought via the Special Protocol Assessment (SPA) mechanism.
Further details, including sample size and other criteria will be available post regulatory review, anticipated in the second half of 2017. While the pivotal trial is being designed, we plan to expand the trial cohort with the view of further dose optimization for the planned pivotal Phase 3 Trial.
