What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This phase 2 trial tests whether combining disitamab vedotin, AK104, and bevacizumab can shrink tumors in people with recurrent or persistent clear cell ovarian cancer. Clear cell ovarian cancer is a rare and aggressive subtype that often stops responding to standard platinum-based chemotherapy. The study enrolls about 39 participants whose tumors show HER2 expression and who have at least one measurable lesion. Researchers will track how many tumors shrink, how long that response lasts, and what side effects occur.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
disitamab vedotin combined with AK104 (a PD-1/CTLA-4 bispecific antibody) and bevacizumab
What this could lead to
If it works, this combination could offer a new treatment option for people with recurrent clear cell ovarian cancer, a type that often resists standard chemotherapy.
What could go wrong
This is a small, early-phase study with no comparison group, so results may not hold up in larger trials. The drug combination can also cause side effects like fatigue, nausea, or immune-related reactions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * The pathological diagnosis confirms ovarian clear cell carcinoma. In cases of mixed carcinoma, a prerequisite is that clear cell carcinoma constitutes at least 70% of the tumor mass. Moreover, adherence to RECIST 1.1 criteria mandates the presence of at least one evaluable lesion. * HER2 IHC ≥1+. * Treatment-naïve individuals encompass those experiencing tumor progression during postoperative chemotherapy and those who, following platinum-containing neoadjuvant chemotherapy, have not undergone surgical intervention yet and subsequently manifested progression during or after platinum-containing chemotherapy, provided that they have received a maximum of 2 prior lines of chemotherapy. * Recurrent patients, whether platinum-sensitive or platinum-resistant, include those lacking a platinum-free interval of ≥6 months and who, post-recurrence, have undergone re-administration of platinum-containing chemotherapy but have demonstrated an inability to tolerate toxic reactions, with a maximum of 2 lines of chemotherapy post-recurrence. * Previous utilization of bevacizumab is permissible. * Adequate bone marrow reserve function necessitates pre-operative blood routine parameters meeting specific criteria: white blood cell count ≥3.0×10\^9/L, neutrophil count ≥1.5×10\^9/L, platelet count ≥100×10\^9/L, and hemoglobin ≥80 g/L. * atisfactory organ function entails biochemical test results within defined limits: AST ≤2.5× upper limit of normal (ULN), ALT ≤2.5× ULN, serum total bilirubin ≤1.5× ULN, and creatinine ≤1.5× ULN. * ECOG performance status score ranging from 0 to 1. * Patient participation is contingent upon voluntary execution of an informed consent form. Exclusion Criteria: * Patients diagnosed with other malignancies within the past five years, excluding skin cancer and thyroid cancer. * Patients with an expected survival of ≤12 weeks. * Patients with a known allergy to taxane-based medications. * Patients who, based on clinical assessment, have contraindications for receiving immunotherapy and/or bevacizumab, such as uncontrolled infections, gastrointestinal fistula, autoimmune diseases, active hepatitis, or active bleeding. Patients currently undergoing treatment with investigational anti-cancer drugs in other clinical trials. * Patients with any unstable condition or situation that may compromise their safety or adherence to the study protocol.
