A Study of Intraperitoneally Administered AVB-001 in Patients With Serous Adenocarcinoma of the Ovary

Stopped early · Phase 1/Phase 2

Conditions studied: Neoplasm, Ovarian, Fallopian Tube Cancer, Primary Peritoneal Cavity Cancer, Adenocarcinoma Ovary, Serous Adenocarcinoma of Ovary, Serous Adenocarcinoma of Primary Peritoneum, Primary Peritoneal Carcinoma, High Grade Serous Adenocarcinoma

In brief

This is an open-label, First-in-Human, Phase 1/2, multicenter study to evaluate the safety and efficacy of a single dose of AVB-001. AVB-001 is an encapsulated cell product engineered to produce native human interleukin-2 (hIL-2). It is delivered intraperitoneally (IP) to patients with high grade serous adenocarcinoma of the ovary, primary peritoneum, or fallopian tube.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Have histologically confirmed, metastatic or unresectable, platinum-resistant, high-grade, serous adenocarcinoma of the ovary, primary peritoneum, or fallopian tube;
• Note: For the purposes of this study, platinum-resistant is defined as a patient who has received platinum-containing chemotherapy and either has platinum-refractory disease (progressed during initial platinum-based chemotherapy) or resistant disease (relapsed within 6 months of initial platinum-containing chemotherapy) or, if previously with platinum-sensitive disease, has received at least 2 lines of platinum-containing chemotherapy and progressed.
• Note: A pathology report confirming histology will be required for enrollment.
• Have not received more than 5 lines of prior therapy;
• May have received poly adenosine diphosphate-ribose polymerase (PARP) inhibitors, bevacizumab (or any other antiangiogenic agent), immunotherapy, or cell therapies. (Patients with germline or somatic breast cancer gene (BRCA) mutations must have progressed or been intolerant to PARP inhibitor therapy);
• Have an Eastern Cooperative Oncology Group performance status 0 to 1 at Screening;
• Meet the following laboratory criteria:
• Absolute neutrophil count >1500/μl;
• Hemoglobin level ≥9.0 g/dL (transfusion allowed);
• Platelet count ≥100,000/μl;
• Creatinine clearance ≥50 mL/minute, measured using the Cockcroft-Gault formula, and serum creatinine ≤1.5 upper limit of normal (ULN);
• Alanine aminotransferase (ALT) ≤2.5× ULN, aspartate aminotransferase (AST) ≤2.5×ULN; and total bilirubin ≤1.5×ULN (or ≤3×ULN in cases of Gilbert's syndrome); and
• International normalized ratio <1.5 and activated partial thromboplastin time (or partial thromboplastin time) within normal limits per the institution.
• Note: Patients on direct-acting anticoagulants or other anticoagulation medications are eligible as long as they are able to hold the drug for the laparoscopic procedure on Day 1 per institutional guidance.
• Have evidence of measurable disease on computed tomography (CT) or magnetic resonance imaging (MRI) scan as defined by RECIST v1.1;
• Note: Measurable disease cannot include a lesion that was biopsied. Patients must, at a minimum, have 1 measurable lesion.
• Note: Patients with IP disease who also have disease involving the pleural cavity or distant metastases will be eligible if they have measurable or evaluable disease in the IP cavity.
• Are willing and able to provide written informed consent or have a legally authorized representative willing and able to provide informed consent at Screening.

You may not qualify if…

• Have low-grade serous, mucinous, clear cell, or endometrioid adenocarcinoma of the ovary, primary peritoneum, or fallopian tube; carcinosarcoma; or a mixed histology tumor;
• Have another malignancy or have had a prior malignancy within 3 years prior to the first dose of study drug or any evidence of residual disease from a previously diagnosed malignancy, excluding adequately managed with curative-intent treatment for basal cell carcinoma, squamous cell carcinoma of the skin, cervical intraepithelial neoplasia, cervical carcinoma in situ, melanoma in situ, or ductal carcinoma in situ of the breast;
• Have a known or suspected allergy to AVB-001 or known or suspected allergy to any components of AVB-001, including alginate or seaweed;
• Have any condition that, in the opinion of the Investigator, would lead to the inability of the patient to comply with the Protocol.
