Subcutaneous Doses of CM-101 as a Treatment for Medical Conditions Involving Inflammatory and Fibrotic Mechanisms in Healthy Male Subjects

Phase 1

Completed

• Conditions: Nonalcoholic Steatohepatitis (NASH); Primary Sclerosing Cholangitis (PSC); Systemic Sclerosis (SSc)
• Interventions: Drug: CM-101; Drug: Placebo

• Registration Number: NCT06037577
• Lead Sponsor: ChemomAb Ltd.

Brief Summary

CM-101 is developed as treatment for medical conditions involving inflammatory and fibrotic mechanisms such as non-alcoholic steatohepatitis (NASH) and primary sclerosing cholangitis (PSC) and systemic sclerosis (SSc). In this current study, the IP is tested in healthy male volunteers.

Detailed Description

A single-center, randomized double-blind, placebo-controlled, single-dose study Healthy volunteers were screened for up to 28 days prior to drug administration. The study included one dose group of 8 subjects. A single 5 mg/kg CM-101 dose was subcutaneously administered. The study was comprised of a screening period, a treatment day, a follow-up (FU) period of 42 days and an end of study (EOS) FU visit.

8. Having received any biological treatment with recombinant antibodies, immunological therapy, or anticancer treatment. Previous standard vaccination treatment is allowed.
9. Positive HIV, hepatitis HBsAg or hepatitis HCV Ab serology tests at Screening.
10. Subjects who donated blood in the 3 months or received blood or plasma derivatives in the 6 months preceding study drug administration.
