Efficacy and Safety of BG-C9074 With Bevacizumab Compared With Bevacizumab in Adults With Ovarian, Fallopian Tube, or Primary Peritoneal Cancers

3 settembre 2026 aggiornato da: BeOne Medicines

A Phase 3, Open-label, Multicenter, Randomized Study of BG-C9074 With Bevacizumab Versus Bevacizumab as First-line Maintenance Therapy for Patients With Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancers Who Have Not Progressed After First-line Platinum-based Chemotherapy Plus Bevacizumab (Starstone-Ovarian 301/GOG-3144/ENGOT-ov108/APGOT-OV29)

The purpose of this study is to evaluate the safety and efficacy of BG-C9074 with bevacizumab (Arm A) versus bevacizumab monotherapy (Arm B) in adults with epithelial ovarian, fallopian tube, or primary peritoneal cancers who have not progressed after firstline platinum-based chemotherapy plus bevacizumab.

Descrizione dettagliata

Ovarian cancer is a disease where abnormal cells in the ovaries or fallopian tubes grow out of control and form tumors. Common early signs include belly bloating, pelvic or back pain, feeling full quickly when eating, and frequent urination.

BG-C9074 is a targeted cancer medicine called an antibody-drug conjugate (ADC). ADC consists of an antibody linked to a drug that can kill cancer cells. The antibody part of BG-C9074 specifically attaches to a protein called B7-H4 that is found on the surface of cancer cells. After it attaches to B7-H4, BG-C9074 enters the cancer cell where the drug causes DNA damage and cell death. Bevacizumab is an approved medicine used to treat these cancers along with chemotherapy. It works by cutting off the blood supply that helps the tumor grow, which may help keep the cancer under better control.

The purpose of this study is to test if BG-C9074 is safe and effective in women with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer when it is given in combination with bevacizumab as a first-line maintenance treatment.

This study has 2 treatment groups. Participants will be randomly assigned (by chance, like flipping a coin) to receive one of the treatments listed below:

  • Arm A: BG-C9074 + Bevacizumab
  • Arm B: Bevacizumab

This study will enroll approximately 600 participants. The overall time to participate in this study may be up to 5 years. Participants will make regular visits to the clinic for treatment, health checks, blood tests, and for tumor and imaging tests.

An adverse event is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment, whether considered related to study treatment or not.

A serious adverse event is any untoward medical occurrence that, at any dose, meets one or more of the criteria listed in the view of either the investigator or the Sponsor:

  1. Results in death
  2. Is life-threatening
  3. Requires inpatient hospitalization or prolongation of existing hospitalization

Lasso di tempo: Baseline and up to approximately 2 years
The EORTC QLQ-F17 is a 17-item questionnaire that covers GHS/QoL and five functional scales (Physical, Role, Emotional, Cognitive, and Social). All items are scored on a 4-point - Likert scale (1 = "Not at all"; 4 = "Very much"), except the two items of the GHS/QoL-scale that are scored on a 7-point scale (1 = "Very poor"; 7 = "Excellent"). Scores are averaged and transformed to a 0 to 100 scale. Higher scores in GHS/QoL and functional scales indicate better health-related quality of life (HRQoL).

Lasso di tempo: Baseline and up to approximately 2 years
The EORTC QLQ-OV28 includes a 28-item questionnaire for evaluating ovarian cancer-specific symptoms and concerns in participants of cancer clinical studies. These include items that assess symptoms in the abdominal/gastrointestinal domain. Scores are averaged and transformed to a 0 to 100 scale; higher scores indicate a greater symptom burden, while lower scores reflect fewer symptoms.
