Vicore Pharma Holding AB (publ) announced that the Phase 1 study of C106 has concluded and that Vicore will not continue further development due to a transient increase in blood pressure observed at doses believed to be in the clinically effective range. The Phase 1 study of C106 (NCT05427253), initiated in June 2022, was designed as a double-blind, placebo-controlled, randomized first-in-human study to evaluate safety, tolerability, and pharmacokinetics of single and multiple ascending oral doses of the drug candidate from 5 to 300 mg. While there were no major safety signals or tolerability concerns in the doses tested, an increase in blood pressure was observed at twice-daily doses of 140 mg and higher.
