OncoMed Pre-Announces 2014 Year-End Cash Balance and Provides 2015 Guidance

Begins 2015 with $232 Million in Cash

Potential Milestones from Existing Partnerships in 2015/2016 Projected at Over $150 Million

REDWOOD CITY, Calif., Jan. 12, 2015 (GLOBE NEWSWIRE) -- OncoMed Pharmaceuticals, Inc. (Nasdaq:OMED), a clinical-stage company developing novel therapeutics that target cancer stem cells (CSCs), or tumor-initiating cells, pre-announced its 2014 year-end cash balance and provided top-line financial guidance for 2015, including anticipated cash spend and additional detail around several key potential financial milestones from existing collaborative partnerships.

  • OncoMed ended 2014 with $232 million in cash, exceeding its updated 2014 guidance predicting year-end cash of over $225 million
  • 2014 full-year operating expenses are anticipated to be $90-95 million, in accordance with previous guidance
  • 2015 cash expenses are expected to total $100-$110 million, excluding non-cash stock-based compensation, depreciation, and amortization expenses
  • OncoMed projects a 2015 year-end cash balance of over $120 million, before considering the receipt of any potential collaboration milestones
  • OncoMed could receive more than $150 million in milestone and option payments from partners during 2015 and 2016
  • OncoMed left unchanged its guidance that existing cash combined with future potential milestones may fund company operations through commercialization without the need for additional financing

"We ended 2014 with a very strong balance sheet, having advanced multiple programs to the next stages of clinical development and maintaining highly productive cancer stem cell and immuno-oncology discovery research," said Paul J. Hastings, OncoMed's Chairman and Chief Executive Officer. "We begin 2015 with six OncoMed-discovered drugs in the clinic, including multiple randomized Phase 2 clinical trials, as well as new pathways and targets being discovered and developed internally. Several significant future milestone payments from our partners may continue to enable our progress through commercialization without additional financing."

2015-2016 Key Financial Milestones

Potential milestones from OncoMed's collaborations with Celgene, Bayer and GlaxoSmithKline (GSK) anticipated in the 2015-2016 timeframe include:

  • Demcizumab safety milestone ($70 million) – OncoMed is eligible to achieve a $70 million milestone from Celgene for successful completion of a Phase 2 interim safety analysis associated with the demcizumab (anti-DLL4, OMP-21M18) program. The safety analysis will be performed by an independent data safety monitoring board (DSMB) using pre-specified cardiopulmonary safety criteria agreed to in the collaboration agreement. At the European Society for Medical Oncology (ESMO) 2014 Congress, OncoMed reported that 64 patients have been treated in the Phase 1b studies of demcizumab using the truncated dosing schedule that will be used in Phase 2. The majority of these patients have now been followed for greater than 100 days without any moderate-to-severe cardiopulmonary toxicities. The timing of potential milestone achievement depends on enrollment of OncoMed's NSCLC (DENALI) and pancreatic cancer (YOSEMITE)Phase 2 trials. OncoMed anticipates the DSMB analysis could occur in late 2015 or early 2016.
  • Wnt program opt-ins ($40 million) – OncoMed is eligible to achieve a $25 million payment upon Bayer's option exercise for vantictumab (anti-Fzd7, OMP-18R5), and $15 million upon Bayer's option exercise for ipafricept (Fzd8-Fc, OMP-54F28). Bayer can elect to exercise its option on these programs at any point through completion of Phase 1b trials. Both programs are currently enrolling in ongoing Phase 1b trials. OncoMed anticipates presenting opt-in data packages to Bayer during the second half of 2015 or first half of 2016, depending on enrollment of Phase 1b trials.
  • Anti-Notch1 opt-in ($18.75 million) – OncoMed anticipates that Phase 1 data sufficient for GSK to determine whether to exercise its option for anti-Notch1 (OMP-52M51) will be available in late 2015 or early 2016. If GSK exercises its option to anti-Notch1 based on Phase 1 data, OncoMed will be eligible to receive an $18.75 million payment. GSK may also elect to defer its decision until the end of Phase 2, in which case the option exercise fee increases to $25 million.
  • Anti-Notch1 Phase 1 dose expansion ($5 million) – OncoMed anticipates enrollment in the near future of the first patient in the expansion cohort of its Phase 1 solid tumor trial of anti-Notch1. The expansion stage of the study will enroll patients whose tumors demonstrate overexpression of the activated form of Notch1. Enrollment of the first patient will trigger a $5 million milestone under OncoMed's collaboration with GSK.
  • Tarextumab opt-in ($25 million) – OncoMed anticipates potential Phase 2 data from the ALPINE pancreatic cancer trial of tarextumab (anti-Notch2/3, OMP-59R5) in the first half of 2016. GSK may exercise its option for tarextumab through the end of the Phase 2 trials of tarextumab. If GSK elects to exercise its option, OncoMed is eligible to receive a $25 million payment.
  • Several other important milestones could also be achieved in 2015/2016 related to preclinical and small molecule programs in OncoMed's Celgene and Bayer collaborations.

OncoMed also outlined anticipated pipeline progress for 2015:

  • Tarextumab:
    • Complete target Phase 2 enrollment of 124 patients in Phase 2 ALPINE pancreatic cancer trial
    • Report final Phase 1b clinical trial results from the ALPINE trial of tarextumab in pancreatic cancer and the PINNACLE study of tarextumab in small-cell lung cancer
    • Present updated biomarker data from the ALPINE and PINNACLE trials
