Immune Design Announces Program Updates & Portfolio Prioritization for G100 and CMB305

  • G100 development to accelerate in follicular lymphoma and beyond
  • CMB305 to be deprioritized to support focus on G100
  • Cash runway extended into 2021
  • Conference call at 2:00 pm Pacific today

SEATTLE and SOUTH SAN FRANCISCO, Calif., Oct. 11, 2018 (GLOBE NEWSWIRE) -- Immune Design (Nasdaq: IMDZ), an immunotherapy company focused on next-generation therapies in oncology, today announced program updates for its G100 intratumoral TLR4 agonist and CMB305 cancer vaccine programs in development for the treatment of cancer.

The company has completed a portfolio review and determined that, given advances in G100 and its broad potential, new CMB305 data, and existing capital, it should focus on accelerating and expanding the development of G100.

  • G100 has a unique mechanism of action that differs from current therapies in lymphoma. It triggers an immune-mediated anti-tumor effect with a favorable safety profile that could position G100 as a pillar of chemo-free regimens for the treatment of lymphomas and beyond.
    • Immune Design’s first goal is to develop G100 in combination with pembrolizumab in follicular lymphoma patients who have received three prior lines of systemic therapy. These patients may represent an unmet medical need, which may allow for an accelerated approval path in this indication.
      • The company will evaluate the clinical activity based on Objective Response Rate (ORR) in an open label setting.
      • To accelerate enrollment, Immune Design plans to use both an open IND and submit a new IND for this specific unmet medical need population, as requested by the FDA.
      • The data from both INDs would be combined in a potential BLA filing.
      • Based on existing ORR data, approximately 100 patients may be required. The final sample size will be adapted depending on the ORR observed in the initial patients.

    • Given its broad potential reach, Immune Design’s second goal is to evaluate G100 beyond late-stage follicular lymphoma.
      • Immune Design intends to evaluate G100 in earlier-stage follicular lymphoma patients in combination with rituximab, the backbone treatment for lymphomas in multiple lines of therapy.
      • The company also plans to explore G100 in combination with other agents in both indolent and aggressive lymphomas that are known to express TLR4.
      • Finally, the company plans to evaluate the safety and efficacy of G100 in solid tumors, initially through supporting investigator-sponsored studies.

  • Based on a recent review of the CMB305 program, including an early analysis of the ongoing Phase 2 study that showed the combination of CMB305 and Tecentriq (atezolizumab) is not likely to show a survival benefit in relapsed synovial sarcoma patients, the company has decided to discontinue the SYNOVATE trial. Immune Design will seek external collaborations to explore the continued development of CMB305 in sarcoma.

This portfolio prioritization and an associated company re-structuring extends Immune Design’s cash runway into 2021, which enables significant potential value creation from the focus on, and expanded development of, G100.
