Summit Therapeutics announced positive topline results from HARMONi, a global Phase III trial evaluating ivonescimab plus chemotherapy in EGFR-mutated non-small cell lung cancer (NSCLC) patients. The study met its primary endpoint, showing a 48% reduction in disease progression or death risk compared to chemotherapy alone (HR=0.52, p<0.00001). The trial also showed a positive trend in overall survival with a hazard ratio of 0.79, though not reaching statistical significance (p=0.057). The safety profile was manageable, with 56.9% of patients in the treatment arm experiencing Grade 3+ adverse events versus 50.0% in the control arm. The study included patients from both Asian (62%) and Western (38%) countries, demonstrating consistent benefits across regions. Summit is considering the timing of a BLA filing, noting FDA's requirement for statistically significant overall survival benefit for marketing authorization.

Summit Therapeutics (NASDAQ: SMMT) reports positive interim overall survival analysis results for ivonescimab from the HARMONi-2 Phase III trial in China. The study, conducted by Akeso, compared ivonescimab monotherapy to pembrolizumab in patients with PD-L1 positive advanced non-small cell lung cancer (NSCLC).

Key findings include:

• Overall survival hazard ratio of 0.777 favoring ivonescimab at 39% data maturity, suggesting a potential 22% reduction in death risk versus pembrolizumab
• Previously reported primary endpoint showed statistically significant improvement in progression-free survival with hazard ratio of 0.51 (p<0.0001)
• Chinese NMPA has approved ivonescimab for this second indication

Summit is currently conducting HARMONi-7, a global Phase III trial evaluating ivonescimab against pembrolizumab in similar patient population, with registrational intent for the US and other regions.

Summit Therapeutics (NASDAQ: SMMT) announced positive results from Akeso's Phase III HARMONi-6 clinical trial, where ivonescimab plus chemotherapy demonstrated statistically significant superiority in progression-free survival (PFS) compared to tislelizumab plus chemotherapy in first-line treatment of squamous non-small cell lung cancer (NSCLC).

The trial, conducted in China, showed meaningful PFS benefits across both PD-L1 positive and negative tumors, with no new safety concerns identified. This marks the first known Phase III trial showing significant improvement over PD-(L)1 inhibitor therapy combined with chemotherapy in NSCLC.

Following the success of HARMONi-2, this is the second instance where ivonescimab-based regimens have shown superior results versus standard-of-care PD-(L)1 inhibitor treatments.
