Phase 1/2a Two-Arm Dose-Escalation Study of BAX69 in Subjects With Malignant Ascites of Ovarian Cancer

Stopped early · Phase 1/Phase 2

Conditions studied: Refractory Ovarian Cancer With Recurrent Symptomatic Malignant Ascites

In brief

The purpose of this study is to evaluate the safety and tolerability of BAX69 monotherapy given either as intraperitoneal (IP) infusion (Single-Route Arm); or as IP infusion after intravenous (IV) infusion (IV+IP) (Double-Route Arm), and to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) for each Arm separately, in subjects with refractory ovarian cancer and recurrent malignant ascites. In both Arms, the plasma pharmacokinetics (PK) of BAX69 will be characterized, and pharmacodynamics (PD) markers will be explored in plasma and ascites. Two expansion cohorts will further assess the tolerability of the RP2D and explore clinical signs of efficacy.

• Adequate liver function, defined as:
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 times ULN for participants without liver metastases, or ≤5 times ULN in the presence of liver metastases
• Bilirubin ≤2.0 times ULN, unless participant has known Gilbert's syndrome
• Adequate venous access
• Participant is willing and able to comply with the requirements of the protocol

You may not qualify if…

• Known central nervous system metastasis that is unstable within the last 2 months
• Prior malignancy within the past 3 years, with the exception of curatively treated basal or squamous cell carcinoma of the skin, ductal carcinoma in situ of breast, in situ cervical carcinoma, and superficial bladder cancer
• Residual AEs >Grade 2 from previous treatment
• Myocardial infarction within 6 months prior to C1D1 treatment, and/or prior diagnoses of congestive heart failure (New York Heart Association Class III or IV), unstable angina, unstable cardiac arrhythmia requiring medication; and/or the participant is at risk for polymorphic ventricular tachycardia (eg, hypokalemia, family history or long QT syndrome)
• Uncontrolled hypertension defined as systolic blood pressure ≥160 mmHg and/or diastolic blood pressure ≥100 mmHg confirmed upon repeated measures
• Left ventricular ejection fraction <50% as determined by echocardiogram (ECHO) performed at screening or within 30 days prior to C1D1
• QT/QTc interval >480 msec, before C1D1 treatment administration, as determined by screening electrocardiogram (ECG)
• Received anti-tumor therapy (chemotherapy, investigational product, radiotherapy, retinoid therapy, or hormonal therapy) within 2 weeks (less than 14 days) prior to C1D1 with no residual toxicity >Grade 1; antibody therapy, molecular targeted therapy within 5 half-lives prior to C1D1

• Known hypersensitivity to any component of recombinant protein production by Chinese Hamster Ovary (CHO) cells
• Any disorder or disease, or clinically significant abnormality on laboratory or other clinical test(s) (eg, blood tests and ECG), that in medical judgment of the investigator may impede the participant's participation in the study, pose increased risk to the participant, and/or confound the results of the study
• Participant is a family member or employee of the investigator
