About this trial

This study is a randomized, open-label, controlled phase II clinical trial.

It is planned to enroll 176 subjects with platinum-sensitive recurrent epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer previously treated with Poly (ADP-ribose) polymerase inhibitors (PARPi).

Subjects will be randomly assigned in a 1:1 ratio to receive either the experimental treatment group (trastuzumab Rezetecan + carboplatin ± bevacizumab) or the control treatment group (investigator's choice chemotherapy ± bevacizumab).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Subjects voluntarily participate in this study, sign the informed consent form, and have good compliance.

Aged 18 to 75 years.

Histologically confirmed epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer.

Have received 1-3 prior lines of platinum-based chemotherapy and have experienced disease progression or recurrence ≥6 months after the last platinum-based treatment (platinum-sensitive relapse).

Disqualifiers

Ovarian cancer with pathological types of clear cell carcinoma, low-grade serous adenocarcinoma, or mucinous adenocarcinoma.

Known allergy to any component of trastuzumab rezetecan; known allergy to carboplatin.

Prior treatment with anti-HER2 therapy, an antibody-drug conjugate (ADC) containing a topoisomerase I inhibitor, or a topoisomerase I inhibitor alone.

Untreated or active central nervous system (CNS) metastases.

Trial outcomes

Primary outcomes

1

Progression Free Survival (PFS)

Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumours (RECIST) v1.1, as determined by investigators.

Time frame
Up to approximately 3 years

Secondary outcomes

1

Objective Response Rate (ORR)

Defined as the proportion of subjects who achieve a Best Overall Response (BOR) of Complete Response (CR) or Partial Response (PR) as assessed by the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1). For responses categorized as CR or PR, confirmation is required through a subsequent evaluation performed no less than 4 weeks (≥28 days) after the initial assessment.

Time frame
Up to approximately 3 years
2

Disease Control Rate (DCR)

Defined as the proportion of subjects with a Best Overall Response (BOR) of Complete Response (CR), Partial Response (PR), or Stable Disease (SD) as assessed by the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).

Time frame
Up to approximately 3 years
3

Duration of Response (DoR)

Defined as the time from the first date a subject is assessed as having a confirmed Complete Response (CR) or Partial Response (PR) to the first date of either Progressive Disease (PD) or death due to any cause, whichever occurs first.

Time frame
Up to approximately 3 years
4

Overall Survival (OS)

Defined as the time from the randomization date to death due to any cause in subjects.

Time frame
Up to approximately 5 years
