Industry Context

The presentation highlights Summit's efforts in the competitive oncology space, particularly in the development of bispecific antibodies. The focus on PD-1 and VEGF targets aligns with current trends in cancer immunotherapy. The partnership with Akeso leverages their expertise in China, a significant market for cancer therapies.

Comparison to Industry Standards

• The Phase II results for ivonescimab in squamous NSCLC, with a 67% ORR and 95% DCR, compare favorably to the KEYNOTE-407 trial for pembrolizumab plus chemotherapy, which showed an ORR of 63% and 80% in global and China extensions respectively.
• The median Overall Survival (mOS) for ivonescimab in squamous NSCLC was not reached, while the KEYNOTE-407 trial showed a mOS of 17.2 months and 30.1 months in global and China extensions respectively.
• In EGFR-mutated NSCLC, ivonescimab's 68.4% ORR and 8.5 months mPFS are competitive with other treatments in this setting, such as amivantamab plus chemotherapy in the MARIPOSA-2 trial, which showed a 64.1% ORR and 6.3 months mPFS.
• The company is positioning ivonescimab as a potential first-in-class PD-1/VEGF bispecific antibody, which would differentiate it from existing therapies.

Stakeholder Impact

• Shareholders may benefit from the potential success of ivonescimab and the company's growth.
