Business Context and Reporting Period
This Form 6-K, furnished on November 18, 2021, reports topline results from Connect Biopharma’s global Phase 2 clinical trial of CBP-201 in adults with moderate-to-severe atopic dermatitis. The company is a foreign private issuer that files annual reports on Form 20-F. The filing does not provide financial statements or financial results for a reporting period.
Clinical and Other Key Metrics
- The randomized, double-blind, placebo-controlled trial enrolled 226 patients aged 18–75 in the United States, China, Australia and New Zealand.
- The 16-week treatment period was followed by an additional eight-week follow-up period.
- Patients received placebo or CBP-201 at 300 mg every two weeks, 150 mg every two weeks, or 300 mg every four weeks, following a 600 mg loading dose on Day 1.
- All three CBP-201 treatment arms were statistically superior to placebo on the primary endpoint: percentage reduction in EASI score from baseline at Week 16.
- All three treatment arms also showed statistically significant improvements versus placebo in EASI-50 and EASI-75 response rates.
- Additional improvements versus placebo were reported for IGA response, weekly average Peak Pruritus Numerical Rating Scale, and other efficacy endpoints.
- The filing describes CBP-201’s safety profile as favorable, with similar incidences of treatment-emergent adverse events, serious adverse events and treatment discontinuations across CBP-201 and placebo groups.
- Reported injection-site reactions occurred in 1.8% of CBP-201-treated patients, and conjunctivitis occurred in 3.5%.
The filing does not provide detailed response percentages, p-values, confidence intervals, financial metrics, cash flow, margins, debt, liquidity, or other balance-sheet information.
