Dual-Targeting CAR-NK Cells for Recurrent Ovarian Cancer (MSLN, FRα, MUC16) pt2

A Phase 1/2, Open-Label, Biomarker-Assigned Study of Dual-Targeting CAR-NK Cells Directed Against Mesothelin (MSLN), Folate Receptor Alpha (FRα/FOLR1), and/or MUC16 (CA125) in Patients With Recurrent or Refractory High-Grade Serous Ovarian, Primary Peritoneal, or Fallopian Tube Cancer

Dual-Targeting CAR-NK Cells for Recurrent Ovarian Cancer (MSLN, FRα, MUC16) pt2 (NCT07617753) is a Phase 1 / Phase 2 interventional studying Epithelial Ovarian Cancer and Primary Peritoneal Carcinoma, sponsored by Beijing Biotech. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

This Phase 1/2 study evaluates the safety, tolerability, and preliminary anti-tumor activity of dual-targeting chimeric antigen receptor natural killer (CAR-NK) cells in participants with recurrent or refractory epithelial ovarian, primary peritoneal, or fallopian tube cancer. At screening, each participant's tumor is assessed for expression of Mesothelin (MSLN), Folate Receptor alpha (FRalpha/FOLR1), and MUC16 (CA 125). Participants are assigned to the dual-target CAR-NK product that best matches their tumor antigen profile to reduce the risk of antigen escape.

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Epithelial Ovarian Cancer, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 36 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: - diagnosed by tissue sample (biopsy-confirmed) epithelial ovarian, fallopian tube, or primary peritoneal carcinoma (high-grade serous preferred). - Recurrent or refractory disease after at least 2 prior systemic treatment lines (including a platinum-based regimen unless contraindicated). - tumors that can be measured on scans v1.1. - Tumor expresses at least two of the following targets above protocol-defined threshold: MSLN, FRalpha (FOLR1), MUC16 (CA 125) (archival or fresh biopsy). - You should be able to carry out daily activities with 0 level of ability (ECOG 0)-1. - your organs (liver, kidneys, etc.) are working well enough based on blood tests : ANC \>= 1.0 x 10\^9/L; platelets \>= 75 x 10\^9/L; hemoglobin \>= 8 g/dL; AST/ALT \<= 3 x ULN (\<= 5 x ULN with liver metastases); total bilirubin \<= 1.5 x ULN; creatinine clearance \>= 50 mL/min. - Negative pregnancy test for women of childbearing potential; agreement to use effective contraception through 12 months post-infusion (or per local gene-therapy guidance). - Able to comply with study procedures and follow-up schedule; written willing to sign a consent form. Who Should NOT Join This Trial: - Prior gene-modified cellular therapy (e.g., CAR-T, CAR-NK) within 6 months (or any prior therapy directed to the same target, per protocol). - Active central nervous system (CNS) metastases or carcinomatous meningitis requiring therapy. - Uncontrolled infection, including active tuberculosis; or clinically significant, uncontrolled viral infection. - Known HIV infection with uncontrolled viremia; active hepatitis B or hepatitis C with detectable viral load (testing required at screening). - Clinically significant cardiovascular disease (e.g., recent myocardial infarction, uncontrolled arrhythmia, NYHA Class III/IV heart failure). ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Inclusion Criteria: * Histologically confirmed epithelial ovarian, fallopian tube, or primary peritoneal carcinoma (high-grade serous preferred). * Recurrent or refractory disease after at least 2 prior systemic treatment lines (including a platinum-based regimen unless contraindicated). * Measurable disease per RECIST v1.1. * Tumor expresses at least two of the following targets above protocol-defined threshold: MSLN, FRalpha (FOLR1), MUC16 (CA 125) (archival or fresh biopsy). * ECOG performance status 0-1. * Adequate organ function : ANC \>= 1.0 x 10\^9/L; platelets \>= 75 x 10\^9/L; hemoglobin \>= 8 g/dL; AST/ALT \<= 3 x ULN (\<= 5 x ULN with liver metastases); total bilirubin \<= 1.5 x ULN; creatinine clearance \>= 50 mL/min. * Negative pregnancy test for women of childbearing potential; agreement to use effective contraception through 12 months post-infusion (or per local gene-therapy guidance). * Able to comply with study procedures and follow-up schedule; written informed consent. Exclusion Criteria: * Prior gene-modified cellular therapy (e.g., CAR-T, CAR-NK) within 6 months (or any prior therapy directed to the same target, per protocol). * Active central nervous system (CNS) metastases or carcinomatous meningitis requiring therapy. * Uncontrolled infection, including active tuberculosis; or clinically significant, uncontrolled viral infection. * Known HIV infection with uncontrolled viremia; active hepatitis B or hepatitis C with detectable viral load (testing required at screening). * Clinically significant cardiovascular disease (e.g., recent myocardial infarction, uncontrolled arrhythmia, NYHA Class III/IV heart failure). * Active autoimmune disease requiring systemic immunosuppression within 30 days (physiologic steroid replacement allowed). * Concurrent anti-cancer therapy (chemotherapy, targeted therapy, radiotherapy) not permitted within a protocol-defined washout period. * Major surgery within 4 weeks prior to lymphodepletion (except minor procedures) * Pregnant or breastfeeding. * Any condition that, in the investigator's judgment, would increase risk (e.g., severe pulmonary disease) or interfere with study interpretation.

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT07617753), the sponsor (Beijing Biotech), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?
