Leerink Global Healthcare Conference 2026 summary9 Mar, 2026

Program highlights and clinical development

  • Focused on developing azenosertib, a Wee1 inhibitor, for platinum-resistant ovarian cancer with high cyclin E1 expression, with DENALI Part 2 trial ongoing for accelerated approval.

  • Enrollment for DENALI Part 2's dose comparison (300 mg vs 400 mg) completed, with a phase 3 confirmatory trial (ASPENOVA) set to begin in the same population.

  • DENALI trial readout expected by year-end 2026, with ASPENOVA designed as a randomized controlled trial to support full approval.

  • Historical studies showed consistent response rates above 30% and manageable tolerability, especially at 400 mg.

  • Dose selection in DENALI is based on efficacy and safety, with the selected dose moving forward for primary outcome analysis.

Clinical landscape and regulatory considerations

  • Standard of care for platinum-resistant ovarian cancer yields low response rates (4%-13%) and minimal PFS benefit, highlighting high unmet need, especially for cyclin E1 high patients.

  • Mirvetuximab has shown ~30% response rates and 5-6 months duration, setting a benchmark for new therapies.

  • Regulatory bar for approval is considered around 30% ORR and 5-6 months duration, with examples like mirvetuximab and CDK4/6 inhibitors cited.

  • ASPENOVA uses an adaptive design to allow early initiation before DENALI readout, aiming for rapid progression to full approval.

  • ASPENOVA targets 420-450 patients, with site expansion planned beyond DENALI.

Expansion strategies and future directions

  • MIRROR trial will explore azenosertib in combination with bevacizumab in second-line maintenance for patients progressing on PARP inhibitors, aiming for early proof of concept.

  • MIRROR will enroll a mix of HRD positive and negative patients, reflecting real-world practice.

  • CCNE1 and HRD status are not mutually exclusive; retrospective analysis will assess biomarker impact.

  • Earlier line strategies are being considered, with pragmatic trial designs to efficiently generate data for broader indications.

  • Ongoing engagement with regulatory agencies to align trial design and enrollment with evolving approval requirements.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
