2017 fourth-quarter revenue was $1.534 million and net loss was $39.040 million, compared with $47,000 of revenue and a $26.935 million net loss in fourth-quarter 2016. Quarterly operating expenses rose to $40.986 million from $27.212 million. The filing provides no meaningful operating margin for this pre-commercial business. It reports no material debt balance; total liabilities were $50.8 million, including $21.9 million of deferred revenue and $1.7 million of deferred rent.

Research and development spending rose 23% year over year, primarily due to higher clinical-trial costs, especially for selinexor. The annual net loss increased despite lower operating cash use, which benefited from the $21.9 million Ono upfront payment recorded as deferred revenue. The company financed operations in part through equity offerings: 2017 net proceeds were $37.0 million from its at-the-market program and $37.9 million from an April follow-on offering.

Business developments, outlook and risks

  • Lead asset: Selinexor, an oral XPO1 inhibitor, was being studied in multiple myeloma, diffuse large B-cell lymphoma, liposarcoma and other cancers. The company reported more than 2,200 patients treated across company- and investigator-sponsored trials.
  • Clinical milestones expected: Management expected expanded-cohort STORM top-line data in April 2018 and planned to seek FDA accelerated approval for selinexor in penta-refractory multiple myeloma in the second half of 2018, contingent on positive results. SADAL data were expected by year-end 2018; BOSTON and the Phase 3 SEAL data were expected in 2019.
  • Other pipeline and licensing: Ono received regional oncology rights to selinexor and eltanexor for an upfront payment of about $21.9 million, with potential milestones and royalties. In January 2018, Biogen acquired KPT-350 assets for $10 million upfront, with potential milestone payments up to $207 million and royalties. These are subsequent events, not 2017 operating revenue. Anivive licensed verdinexor for animal cancer indications.
  • Runway and funding: Management expected year-end 2017 cash and investments, together with the $10 million Biogen payment received in 2018, to fund current operating and capital plans through at least the first quarter of 2019. The company anticipated higher R&D and commercialization expenses and stated it would need additional funding over time.
  • Material clinical and execution risks: Selinexor and other candidates remained investigational, and trial outcomes or regulatory approval were uncertain. SOPRA, a Phase 2 trial in elderly relapsed/refractory AML, was stopped after the company and DSMB determined it was unlikely to show statistically significant overall-survival superiority. Selinexor’s reported adverse events included nausea, fatigue, anorexia, vomiting and thrombocytopenia; serious safety and tolerability risks remain relevant.
  • Regulatory and operational risks: FDA partial clinical holds on selinexor trials in 2017 were lifted after deficiencies in the investigator brochure were addressed. The company relied on third-party manufacturers, had no long-term or redundant supply arrangements, and faced reimbursement, competition, patent and financing risks.

Important facts for investors to verify

  • Whether expanded STORM results supported an NDA and whether FDA accepted the proposed accelerated-approval pathway.
  • Actual cash burn, subsequent financing and the duration of runway relative to the company’s stated first-quarter 2019 estimate.
  • Whether later pivotal trials confirmed the interim efficacy findings, including the Phase 3 BOSTON and SEAL outcomes.
  • Selinexor’s final safety profile, dose modifications and treatment discontinuations in larger studies.
  • Recognition and cash timing of Ono consideration, and the terms and progress of Biogen’s milestone and royalty opportunities.
  • Manufacturing capacity and supply redundancy ahead of any potential commercial launch.
