Awards & highlights


This trial is testing a new drug to see if it is safe and effective when used with another drug to treat cancer.

Who is the study for?
This trial is for adults over 18 with high-grade serous ovarian, fallopian tube, or primary peritoneal cancer. They should have a life expectancy of more than 3 months and at least one measurable lesion. Participants need good kidney, bone marrow, and liver function but can't join if they've had certain treatments like FolRα targeting agents or are pregnant/breastfeeding without using barrier contraception.Check my eligibility
What is being tested?
The study tests STRO-002 combined with Bevacizumab in patients with epithelial ovarian cancer to evaluate safety and early effectiveness. It's a Phase 1 trial where participants' response to the treatment is monitored through various health parameters.See study design
What are the potential side effects?
While specific side effects aren't listed here, typical reactions may include issues related to antibody-drug conjugates such as allergic reactions, lowered blood cell counts leading to increased infection risk or bleeding problems, fatigue, nausea, and potential organ damage.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Part 1 - Determine the recommended phase 2 dose (RP2D) of STRO-002/bevacizumab
Part 1 - Safety and tolerability of STRO-002/bevacizumab as a combination therapy
Secondary outcome measures
Part 1 - Assess the formation of anti-drug antibodies (ADAs) to STRO-002 when administered with bevacizumab.
Part 1 - Characterize the PK of STRO-002 by measuring the area under the plasma concentration versus time curve (AUC)
Part 1 - Characterize the pharmacokinetics (PK) of STRO-002 by measuring the maximum plasma concentration (Cmax).

Other Research
STRO-002 is an antibody-drug conjugate that targets folate receptor alpha, delivering cytotoxic agents directly to ovarian cancer cells, thereby minimizing damage to healthy cells. Bevacizumab, on the other hand, is a monoclonal antibody that inhibits VEGF, preventing the formation of new blood vessels that tumors need for growth and metastasis. These targeted therapies are significant for ovarian cancer patients as they offer the potential for improved efficacy and reduced side effects compared to traditional chemotherapy.
