Study of APL-2, Pembrolizumab, and Bevacizumab for Recurrent Ovarian, Fallopian Tube, or Peritoneal Cancer

This study is for women aged 18 or older with recurrent ovarian, fallopian tube, or primary peritoneal cancer that has returned and caused a buildup of fluid and cancer cells (malignant effusion). It compares three treatment approaches: APL-2 (pegcetacoplan) with pembrolizumab, APL-2 with pembrolizumab and bevacizumab, or bevacizumab alone. Researchers want to see if APL-2 can help slow tumor growth, reduce fluid buildup, and improve the body's immune response against cancer. Pembrolizumab and bevacizumab are both monoclonal antibodies that may help the immune system fight cancer and stop cancer cells from growing and spreading. The study aims to understand the safety of these treatments and their effect on the accumulation of malignant effusion. This study is currently recruiting 60 participants, but its status is unclear.

Study design

What's involved
Participants will receive Bevacizumab, Pegcetacoplan, and/or Pembrolizumab intravenously (IV) or subcutaneously (SC). They will also undergo tumor biopsies and blood sample collection.
Compensation
Not stated in the trial record.
Follow-up
Adverse events will be measured up to 30 days after the last dose. Accumulation of effusion will be measured for up to 3 years.

Creatinine: =\< 1.5 X upper limit of normal (ULN) OR measured or calculated creatinine clearance \>= 60 mL/min (Cockcroft-Gault Equation) for participant with creatinine levels \> 1.5 X institutional ULN. GFR can also be used in place of creatinine or creatinine clearance (CrCl)
Total bilirubin: =\< 1.5 X ULN OR direct bilirubin =\< ULN for participants with total bilirubin levels \> 1.5 ULN
Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase \[SGOT\]) and alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\]): =\< 2.5 X ULN OR =\< 5 X ULN for participants with liver metastases
Albumin: \> 2.5 gm/dL
International Normalized Ratio (INR) or Prothrombin Time (PT): =\< 1.5 unless participant is receiving anticoagulant therapy as long as PT or activated partial thromboplastin time (aPTT) is within therapeutic range of intended use of anticoagulants
Activated Partial Thromboplastin Time (aPTT): =\< 1.5 X ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants
A woman of childbearing potential must have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
Participants of childbearing potential must be willing to use 2 methods of birth control or be surgically sterile or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication (participants of childbearing potential are those who have not been surgically sterilized or have not been free from menses for \> 1 year).

  • Incidence of adverse events (Phase 2a)Up to 30 days after last dose

    Toxicities and adverse events (as per Common Terminology Criteria for Adverse Events version 5.0) will be summarized by cohort and grade using frequencies and relative frequencies.

  • Accumulation of effusion (Phase 2b)Up to 3 years

    Will determine the effect of therapy on accumulation of effusion measured by total volume removed every 3 weeks. The change in accumulation of effusion (relative to pre-treatment) will be modeled as a function of cohort, time-point, their two-way interaction, baseline levels, and a random subject effect using a linear mixed model. The change will be compared: a) over-time within each cohort, and b) between the control cohort (cohort C) and each dosing cohort (cohorts A and B) using two-sided Bonferroni or Dunnet adjusted tests about the appropriate contrasts of model estimates. The model assumptions will be evaluated graphically, and transformations will be applied as appropriate.
