    Bristol Myers Squibb lung cancer candidate doubles progression-free survival

    Question

    Bristol Myers Squibb lung cancer candidate doubles progression-free survival

    Direct answer

    Bristol Myers Squibb disclosed positive top-line data from a Phase 3 study evaluating izalontamab brengitecan in non-small cell lung cancer. Patients treated with iza-bren achieved median progression-free survival of 11.1 months, compared to 5.7 months for those on chemotherapy regimens, effectively doubling survival without disease progression. Despite the statistically significant trial results, immediate equity share movement remained muted. Analysts note that commercial upside will depend on overall survival maturity and competitive positioning against established antibody-drug conjugate regimens in refractory lung cancer settings.
