Study to Assess the Efficacy and Safety of Rina-S Plus Standard of Care Compared to Standard of Care for Maintenance Treatment of Participants With Recurrent Platinum-sensitive Ovarian Cancer After Second-line (2L) Platinum-based Doublet Chemotherapy
(RAINFOL-04)
What this study is about
This Phase 3 study will be conducted in different countries around the world with up to about 528 participants. The purpose of this study is to evaluate how well Rina-S works against ovarian cancer in combination with available the usual treatment therapy that is already approved and used for ovarian cancer.
View original scientific description
This Phase 3 study will be conducted in different countries around the world with up to about 528 participants. The purpose of this study is to evaluate how well Rina-S works against ovarian cancer in combination with available standard of care therapy that is already approved and used for ovarian cancer. Participants will receive either Rina-S monotherapy (by itself), Rina-S plus bevacizumab, bevacizumab (standard of care) by itself, or no treatment (only monitoring, also standard of care). No participants will be given placebo. Participants will participate in 1 of 2 arms. The treatment duration will be different for every participant. If a participant's cancer stays the same or gets better, and there are not any serious problems, participants can keep getting study treatment for as long as the study is open. Participants will be asked to attend 1 to 3 visits at the study clinic for each cycle (duration of cycle is 3 weeks). During visits, there will be various tests (such as blood draws) and procedures (such as recording of heart activity and imaging) to monitor whether the study treatment is safe and effective. The overall study duration (including screening, treatment, and follow-up) for each participant will be different for every participant.
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
- Must have histologically or cytologically confirmed high-grade serous or endometrioid epithelial ovarian cancer (EOC), primary peritoneal cancer, or fallopian tube cancer.
- Must have PSOC defined as progressive disease \> 6 months (ie, 183 days) from the last dose of primary (first-line \[1L\]) platinum therapy.
- Participants with known breast cancer (BRCA)-mutated (somatic or germline) or homologous recombination deficiency (HRD)-positive ovarian cancer who achieved complete response (CR)/no clinical evidence of disease (NED) or partial response (PR) following 1L platinum-based chemotherapy regimen must have previously received PARPi maintenance therapy as part of their 1L treatment.
- Must have completed platinum-based chemotherapy in the 2L treatment for recurrent PSOC.
- Must be randomized no later than 8 weeks from the last dose of the 2L platinum-based therapy.
- Participants must have achieved a CR/NED, PR; or SD permitted only if bevacizumab was given in 2L in combination with platinum-based chemotherapy, as assessed by the investigator, following completion of 2L platinum-based chemotherapy. Key
Exclusion criteria
- Participants with clear cell, mucinous, or sarcomatous histology, mixed tumors containing any of the above histologies, or low-grade/borderline ovarian tumors
- More than 2 prior lines of systemic therapy.
- Progression while on or following 2L platinum-based regimen prior to randomization.
- Participants who receive an intervening systemic anticancer treatment (excluding bevacizumab) after the last dose of 2L platinum-based chemotherapy and prior to randomization. Note: Other protocol-defined Inclusion and Exclusion criteria may apply.

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.
