A Clinical Trial to Test the Safety, Tolerability, and How the Body Processes CPV-104 in Healthy People and Patients With C3-Glomerulopathy
Trial Parameters
Brief Summary
This study is the first time the new medicine CPV-104 is being tested in people. CPV-104 is designed to regulate the complement system, which can be overactive in diseases such as C3 glomerulopathy (C3G), an ultra-rare kidney disorder. The study includes healthy adults and adult patients with C3G to assess safety, tolerability, how the body processes the medicine, and whether the immune system reacts to it. The study is divided in two part; in Part 1 (SAD), healthy volunteers receive one IV dose of CPV-104 or a placebo while in Part 2 (MAD) patients with C3G receive four weekly IV doses of CPV-104 (no placebo). Participants will have close monitoring, including side-effect checks, blood and urine tests, ECGs, vital signs, and blood samples to measure drug levels and antibodies. For those with C3G, researchers will also observe kidney function, although the main goal is safety, not testing effectiveness. A Safety Review Committee will regularly review results to ensure it is safe to continue to the next dose or study group.
Eligibility Criteria
Inclusion Criteria Healthy Volunteers (Part 1 - SAD-HV) : * Participants must be at least 18 years old and no more than 50 years old, at the time of consent, and must be able to sign and date the informed consent form (ICF) themselves. * Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring. A participant with a clinical abnormality or laboratory parameter(s) not specifically listed in the exclusion criteria that is outside the reference range for the population being studied may be included only if the investigator, in consultation with the Medical Monitor, agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures or results. * Body weight within 50 kg for male/ 45 kg for female to 110 kg and BMI within the range 18 - 32 kg/m2 (inclusive). * Childbearing potential (CBP) participants should agree to use
