Study to Assess Safety and Tolerability of OPN-6602 in Subjects With Relapsed and/or Refractory Multiple Myeloma
What this study is about
Phase 1b, where both patients and doctors know the treatment given study evaluating the safety, tolerability, how the drug moves through the body, preliminary antitumor activity, and how the drug affects the body of OPN-6602 treatment given alone and in combination with dexamethasone in subjects with relapsed and/or refractory MM.
View original scientific description
Phase 1b, open-label study evaluating the safety, tolerability, pharmacokinetics, preliminary antitumor activity, and pharmacodynamics of OPN-6602 monotherapy and in combination with dexamethasone in subjects with relapsed and/or refractory MM.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Confirmed diagnosis of multiple myeloma (MM)
- Relapsed or refractory to 3 or more different prior lines of therapy for MM that included immunomodulatory agents, proteosome inhibitors, and anti-CD38 antibody and not a candidate for or intolerant to established therapy known to provide clinical benefit
- Adequate hematologic, renal, liver, cardiac function
Exclusion criteria
- Monoclonal gammopathy of undetermined significance (MGUS), smoldering myeloma, Waldenström's macroglobulinemia, or IgM myeloma
- Active plasma cell leukemia
- Polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes (POEMS syndrome)
- Prior Stevens Johnson syndrome
- Localized radiation therapy to disease site(s) within 2 weeks of the first dose
- Prior autologous peripheral stem cell transplant or prior autologous bone marrow transplantation within \<90 days of the first dose of study drug
- Prior allogeneic stem cell transplantation or solid organ transplantation within 12 months of first dose of study drug; subjects receiving immunosuppressive medication for active graft vs host disease will be excluded.
- Prior chemotherapy, targeted anticancer or radiation therapy within 2 weeks prior to first dose of study drug
- Concomitant high-dose corticosteroids (except subjects on chronic steroids given for disorders other than myeloma)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
