Benitec Biopharma reports positive interim BB-301 Phase 1b/2a results for high dose
Benitec Biopharma announced positive interim Phase 1b/2a clinical results for high dose BB-301 and continued durable improvements for low dose BB-301 in patients with oculopharyngeal muscular dystrophy (OPMD). The company reports a 100% responder rate across all patients treated to date and no serious adverse events, but the filing contains clinical data only, with no financial results, and the company cautions that interim results may not be maintained.
Key points
- All six Cohort 1 (low dose) patients and all three Cohort 2 (high dose) patients are formal responders to BB-301.
- At 3 months, 100% of Cohort 2 patients met the statistical criteria for improved throat emptying ability, versus 67% of Cohort 1 patients.
- No serious adverse events have been reported in any patient treated with BB-301 to date.
- The company plans a pivotal study of BB-301 in mid-2027.
