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.

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 a highly effective method of contraception throughout the study and for 90 days after the last dose of the IMP.
* CBP participants should agree not to donate oocytes or freeze for future use for the purposes of assisted reproduction during the study and for a period of 90 days after the last dose of the IMP. Male participants should agree not to donate sperm or freeze sperm for future use for the purposes of assisted reproduction during the study and for a period of 90 days after the last dose …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
