About this study

Ovarian cancer is one of the three major malignant tumors of the female reproductive system. Even if newly diagnosed ovarian cancer patients undergo ideal tumor cell reduction surgery and postoperative chemotherapy, 70% to 80% of ovarian cancer patients still experience recurrence. According to the length of PFI (platinum free interval), recurrent ovarian cancer (ROC) can be classified into platinum resistant ROC (<6 months) and platinum sensitive ROC (>6 months). There is currently no optimal treatment plan for platinum resistant ovarian cancer (PROC), and the prognosis for patients is poor. The guidelines recommend non platinum monotherapy chemotherapy for patients with PROC, but non platinum monotherapy has a low objective response rate (ORR) (<20%), progression free survival (PFS) (<4 months), and overall survival (OS,<12 months), with significant adverse reactions and affecting quality of life. Therefore, PROC patients urgently need new and better treatment options.

Antibody conjugated drugs (ADCs) have made breakthrough therapeutic progress in multiple tumor types, and currently ADCs have been approved by the FDA for the treatment of cervical cancer and ovarian cancer. HER2 (Human Epidermal Growth Factor Receptor 2) is a member of the epidermal growth factor receptor (EGFR) family, also known as the tyrosine protein kinase receptor. Research has shown that HER2 expression is associated with poor prognosis in ovarian cancer, and patients with HER2 positive expression have a worse prognosis. Vidiximab (RC48) is a novel HER2 antibody conjugate drug that received Breakthrough Therapy Design from the US Food and Drug Administration (FDA) in April 2020. Preclinical studies of ovarian cancer have shown that vediximab exhibits effective cytotoxicity against HER2 expressing ovarian tumor cell lines. Meanwhile, the registration study of RC48 for gynecological tumors is underway, and its latest data was reported at the 2024 European Congress of Gynecological Oncology (ESGO), which showed that in patients with recurrent or metastatic cervical cancer, the ORR of RC48 monotherapy was 36.4%, the median PFS was 4.37 months, and the 1-year OS was 66%. Compared to other chemotherapy drugs, it also has significant advantages in terms of toxic side effects, with severity mostly ranging from grade 1-2. Symptomatic treatment can achieve complete recovery or relief.

Anti angiogenic drugs, including anti vascular endothelial growth factor (VEGF) antibodies and multi-target tyrosine kinase inhibitors (TKIs), are considered potential targets for treating platinum resistant/refractory ovarian diseases . Anlotinib is a novel oral multi-target tyrosine kinase inhibitor (TKIs) . Monotherapy for PROC has achieved initial efficacy, with an ORR of 31.2%, a median PFS of 5.3 months, and a 12-month OS rate of 90.9%. In terms of safety, most of the toxic side effects are grade 1-2.

Good progress has been made in preclinical and clinical trials of ADC in combination with other anti-cancer drugs, including chemotherapy, molecular targeted drugs, anti angiogenic drugs, and immunotherapy. Among them, anti angiogenic drugs may promote the penetration and exposure of ADC to tumor cells, playing a mutually reinforcing role. Research on the combination of RC48 and anlotinib is also actively underway in other tumor types.

In summary, this study creatively conducted exploratory research in clinical PROC patients based on the different expression levels of the molecular target HER2, and adopted targeted medication according to the molecular target. At the same time, in terms of combination therapy, low toxicity and high efficiency, different toxic side reaction spectra, different mechanisms of action, and synergistic effects of dual anti-tumor drugs were selected for combination therapy. Based on the above evidence, an exploratory study was conducted on the safety and efficacy of vediximab combined with anlotinib in the treatment of HER-2 expressing recurrent platinum resistant ovarian cancer, aiming to explore the efficacy of vediximab combined with anlotinib in PROC patients, in order to further improve the remission rate and quality of life of patients while prolonging their survival.

  3. Disease Control Rate (DCR): The proportion of subjects with the best overall response (BOR) evaluated according to RECIST 1.1 criteria as complete response (CR), partial response (PR), and disease stability (SD).

    Measured: From the initial use of medication until disease progression, death, initiation of new anti-tumor treatment, loss to follow-up, withdrawal of informed consent, and completion of the study, evaluation is conducted for 2 years.

  4. Duration of Response (DoR): defined as the period from the first recorded tumor response (assessed according to RECIST 1.1 criteria) to the first recorded objective tumor progression (assessed according to RECIST 1.1 criteria) or death from any cause.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 28 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact jingjing Wang (86+13574841167, wangjingjing78@csu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective response rate (ORR): The proportion of subjects whose best overall response rate (BOR) is evaluated as complete response (CR) or partial response (PR) according to RECIST 1.1 criteria. (time frame: From the initial use of medication until disease progression, death, initiation of new anti-tumor treatment, loss to follow-up, withdrawal of informed consent, and completion of the study, evaluation is conducted for 2 years.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2024.
