A Study of Olaparib Prior to Surgery and Chemotherapy in Ovarian, Primary Peritoneal, and Fallopian Tube Cancer (NEO)

January 14, 2024 updated by: University Health Network, Toronto

A Phase II, Open-Label, Randomized, Multi-Centre Study, of Neoadjuvant Olaparib in Patients With Platinum Sensitive Recurrent High Grade Serous Ovarian/Primary Peritoneal or Fallopian Tube Cancer

This is a study that will look at the effects and how useful investigational drug olaparib is as a neoadjuvant treatment (treatment given as to shrink a tumor before the main treatment) prior to surgery in patients with recurrent ovarian, primary peritoneal or fallopian tube cancer.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Olaparib belongs to a class of anti-cancer agents known as poly ADP-ribose polymerase (PARP) inhibitors. Olaparib is a new type of drug for ovarian cancer. Laboratory tests show that it may help slow the growth of ovarian cancer.

Olaparib works by blocking the PARP protein. PARP is an important protein which tries to fix damaged deoxyribonucleic acid (DNA, molecules that contain important instructions for the development of cells). Many cancers are thought to develop from damaged DNA. Research has shown that PARP inhibitors stop the PARP protein from working, and that sometimes that can cause cancer cells to stop growing or die.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Histologically proven recurrent high grade serous ovarian/primary peritoneal or fallopian tube cancer.
  • Patients must have disease amenable to pre-operative biopsy.
  • Patients must have disease deemed suitable for surgical debulking.
  • Patients must have a progression free interval of at least 6 months prior to registration.
  • Patients must have had at least one line of platinum based therapy.
  • Patients must have shown platinum sensitivity to their last line of platinum therapy
  • Age >=18 years
  • ECOG performance status 0-1 within 7 days of registration

  • Women of child-bearing potential must agree to use adequate contraception prior to study entry and for the duration of study participation.
  • Ability to understand and the willingness to sign a written informed consent document.
  • Subject's willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.

Exclusion Criteria:

  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to olaparib.
  • History of allergic reactions attributed to platinum precluding further use.

  • Previously received a PARP inhibitor
  • Other malignancy within the last 2 years with exceptions
  • Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection.
  • Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication.
  • Concomitant use of known potent CYP3A4 inhibitors
  • Concomitant use of known potent CYP3A4 inducers
  • Other anti-cancer therapy including immunotherapy, hormonal therapy, biological therapy, other novel agents or investigational agents

  • Patients with brain metastases
  • Immunocompromised patients, e.g., patients who are known to be serologically positive for human immunodeficiency virus (HIV)
