Innovent's IBI363 Shows Strong Survival Benefits in Immunotherapy-Resistant Lung Cancer
Event summary
- Innovent Biologics' IBI363 demonstrated robust survival benefits in long-term follow-up of a Phase 1 PoC study in advanced immunotherapy-resistant non-small cell lung cancer (NSCLC).
- In the 3 mg/kg Q3W dose group for squamous NSCLC, median overall survival (OS) reached 18.2 months with a 24-month OS rate of 47.8%.
- For EGFR wild-type adenoNSCLC, median OS achieved 15.2 months in the 3 mg/kg dose group, with a 24-month OS rate of 42.7%.
- IBI363 showed a favorable safety profile with treatment-emergent adverse events (TEAEs) of grade 3 or above in 48.5% of patients.
- Innovent has initiated a global Phase 3 clinical study (MarsLight-11) for IO-resistant squamous NSCLC and plans a similar study for non-squamous NSCLC pending regulatory communications.
The big picture
Innovent Biologics' IBI363 represents a significant advancement in the treatment of immunotherapy-resistant NSCLC, a patient population with limited therapeutic options. The robust survival benefits demonstrated in long-term follow-up underscore the potential of IBI363's unique dual mechanism of immune checkpoint blockade and cytokine agonism. The strategic partnership with Takeda for global co-development and commercialization positions Innovent to potentially capture a substantial share of the oncology market.
