Liposomal Irinotecan Plus Enlonstobart for Platinum-Resistant Recurrent Ovarian Cancer
30 participantsStarted 2026-05-30
Plain-language summary
This is a prospective, single-center, single-arm exploratory clinical study designed to evaluate the efficacy and safety of liposomal irinotecan combined with enlonstobart in patients with platinum-resistant recurrent ovarian cancer.
Eligible female participants with histologically or cytologically confirmed epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer, FIGO stage II-IV, will receive liposomal irinotecan and enlonstobart every 2 weeks. Tumor assessment will be performed every 8 weeks. Participants may discontinue study treatment in the event of disease progression, intolerable toxicity, withdrawal of consent, or other reasons judged by the investigator.

Inclusion criteria
. Female participants aged 18 to 75 years, inclusive, at the time of signing informed consent.
. Histologically or cytologically confirmed epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer, FIGO stage II-IV.
. Platinum-resistant recurrent disease, defined as disease progression within 6 months after the last platinum-containing chemotherapy, and not platinum-refractory disease, defined as disease progression within 4 weeks after initial platinum-containing chemotherapy. Participants may have received up to two prior lines of non-platinum systemic therapy. Treatment with a PARP inhibitor or anti-angiogenic therapy after platinum-resistant recurrence will be counted as one line of therapy; maintenance treatment with a PARP inhibitor or anti-angiogenic therapy will not be counted as a treatment line.
. Ability to provide sufficient qualified formalin-fixed paraffin-embedded tumor tissue samples or slides for PD-L1 testing. Participants who are unable to provide tumor tissue slides for certain reasons may be enrolled at the investigator's discretion.
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.

. At least one measurable lesion at baseline according to RECIST version 1.1. The measurable lesion must not have received prior local therapy such as radiotherapy. A lesion located within a previously irradiated area may be selected as a target lesion if disease progression has been confirmed.
. ECOG performance status of 0 or 1.
. Expected survival of at least 3 months.
. Adequate organ function, meeting all of the following criteria without blood transfusion, hematopoietic stimulating factors, or medication correction of blood cell counts within 14 days before the first dose:
Exclusion criteria
. History of severe hypersensitivity reaction to monoclonal antibody preparations or uncontrolled allergic asthma.
. Known untreated central nervous system metastases, or treated but still symptomatic central nervous system metastases. Participants with residual signs or symptoms related to central nervous system treatment may be eligible if neurological symptoms have been stable or improved for at least 2 weeks before screening.
. History of primary immunodeficiency.
. Active autoimmune disease or history of autoimmune disease. Participants with well-controlled type 1 diabetes mellitus, well-controlled hypothyroidism requiring only hormone replacement therapy, skin diseases not requiring systemic treatment such as vitiligo, psoriasis, or alopecia, or conditions not expected to recur without external triggers may be eligible for further screening.
. Serious arterial or venous thrombotic events within 3 months before screening, such as transient ischemic attack, cerebral hemorrhage, cerebral infarction, deep venous thrombosis, or pulmonary embolism.
. History of interstitial lung disease, except localized radiation-induced interstitial pneumonia, or noninfectious pneumonia requiring glucocorticoid therapy.
. Prior treatment with any antibody or drug targeting T-cell costimulatory or immune checkpoint pathways, including PD-1, PD-L1, PD-L2, CTLA-4, OX40, or CD137 inhibitors.
. Prior immune-related adverse event of CTCAE version 5.0 Grade 3 or higher after immunotherapy.
