Frequently asked questions about CBP-307

What is CBP-307 used for?

CBP-307 is an investigational small molecule being developed for autoimmune diseases, including moderate to severe ulcerative colitis. It has been studied in healthy adult subjects as well. The drug is in clinical development and is not approved by the FDA.

Who makes CBP-307?

CBP-307 is being developed by Connect Biopharma Holdings Limited, a biopharmaceutical company traded on the NASDAQ under the ticker symbol CNTB. The company has conducted clinical trials of CBP-307 in multiple countries.

What phase is CBP-307 in?

CBP-307 has completed Phase 1 and Phase 2 clinical trials. The Phase 2 trial evaluated the drug in patients with moderate to severe ulcerative colitis. CBP-307 remains investigational and is not FDA approved.

What clinical trials is CBP-307 in?

CBP-307 has been studied in several completed trials, including NCT02280434 (Phase 1 safety and tolerability in autoimmune diseases), NCT04700449 (Phase 2 efficacy and safety in ulcerative colitis), NCT04818229 (Phase 1 QT interval study), and NCT05040113 (Phase 1 mass balance study).

Is CBP-307 the same as other drugs?

CBP-307 is a distinct investigational small molecule developed by Connect Biopharma. No alternative names for CBP-307 have been reported in the clinical trial data.
