About this study

Official title: Phase IIA Trial of Delayed Initiation of Olaparib Maintenance Therapy in Platinum Sensitive Recurrent Ovarian Cancer

The purpose of this study is to test if delaying the start of the olaparib until there is a rise in a tumor marker called CA-125 will result in a longer time until the next or different treatment for the patient's cancer. The study will also evaluate how delaying the start of maintenance therapy will affect symptoms; physical functioning; quality of life; and impact on finances.

Read the detailed description

This is a Phase II trial will investigate if waiting until the time of chemical recurrence, denoted by rising CA125, to start a PARP inhibitor will lead to an improved time to next therapy with improved quality of life and at a lower financial toxicity.

PARP-I have shown efficacy as both monotherapy and as maintenance therapy. This trial will explore whether patients with recurrent ovarian cancer could derive the same efficacy benefit from a delayed start of a PARP-I compared to immediate maintenance therapy. Delayed start would have the benefit of sparing the physical, psychological, and financial toxicity associated with prolonged treatment. This approach would be particularly relevant in a population of platinum-sensitive patients who can have prolonged treatment-free intervals.

With widespread use of PARP-I, regardless of timing, understanding, and overcoming PARP-I resistance is becoming a major clinical need.

Enrollment will start within 8 weeks of completion of platinum-based treatment. Monitored with CA 125 levels every 28 days. Olaparib will be started when CA 125 rises by two-fold of their nadir value. Olaparib will be dosed at 300 mg orally twice a day, 28 days of treatment will be a cycle. Follow-up will consist of CA125 drawn every 28 days and CT scans obtained at doubling of CA- 125 and then every 12 weeks* to assess for recurrence or progression. Clinician- and patient-reported adverse events recorded every 28 days. Cancer-related worry and distress assessed every 28 days. Measures of quality of life and physical function, and financial toxicity assessed every 12 weeks.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • OlaparibDrug

    Also called Lynparza™

    Olaparib is a potent oral poly (ADP-ribose) polymerase (PARP) inhibitor that induces synthetic lethality in BRCA1/2 deficient tumor cells through the formation of double-stranded DNA breaks which cannot be accurately repaired, which leads to disruption of cellular homeostasis and cell death.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to Next Therapy

    The time to next therapy from completion of platinum-based therapy for treatment of recurrence until initiation of post-olaparib treatment.

    Measured: Up to 35 months

Secondary outcomes (8)
  1. Progression-free Survival (PFS)

    Progression-free survival (PFS) defined as time from enrollment until detected recurrence or progression of disease, via Response Evaluation Criteria in Solid Tumors , or death from any cause.. Per RECIST 1.1, Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).

    Measured: Up to 35 months

  2. Overall Survival (OS)

    Overall survival as defined as the time from enrollment to death from any cause.

    Measured: Up to 35 months

  3. Overall Response Rate (ORR)

    The proportion of patients with a best overall response of Complete Response (CR) or Partial Response (PR), per Response Evaluation Criteria in Solid Tumors (RECIST v1.1). Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    Measured: Up to 35 months

  4. The Functional Assessment of Cancer Therapy + Ovarian-specific Scale (FACT-O)

    Health-related quality of life measured via The Functional Assessment of Cancer Therapy + Ovarian-specific scale (FACT-O). The FACT-O includes a list of statements that [other] people with ovarian cancer have said are important. The patient is asked to circle or mark one number per line to indicate their response as it applies to the prior 7 days. The scoring ranges from 0 (Not at all) to 4 (very much).

    Measured: Up to 37 months

  5. PROMIS Physical Function-20a

    Physical function assessed through the PROMIS Physical Function-20a assesses self-reported performance of physical activities. The PROMIS includes a list of statements related to physical performance, with scores of 0 (Always) to 5 (Rarely).

    Measured: Up to 35 months

  6. Assessment of Survivor Concerns (ASC) Worry Subscale and Impact of Event Scale (IES-R)

    The Assessment of Survivor Concerns (ASC) Worry Subscale and Impact of Event Scale (IES-R) will be used to measure worry and distress. The assessment includes a list of statements related to worry and stress experience during the patients prior, with responses ranging from 0 (Not at all) to 4 (Extremely). This assessment includes three subscales, the Intrusion subscale, the Avoidance subscale and the Hyperarousal subscale, which are each related to specific questions.

    Measured: Up to 35 months

  7. Modified Collection of Indirect and Non-medical Direct Costs (COIN)

    Financial toxicity measured through (a) monetary measure using the Modified Collection of Indirect and Non-medical Direct Costs (COIN), (b) objective measure of financial burden assessed using Barrera et al's Economic Hardship questionnaire, and (c) subjective measure of financial distress will be gauged using the Comprehensive Score for Financial Toxicity (COST Measure).

    Measured: Up to 35 months

  8. Adverse Events Possibly, Probably or Definitely Related to Treatment

    The number of patients that experience Adverse Events per Common Terminology Criteria for Adverse Events (CTCAE) v5.0 that were determined to be possibly, probably or definitely related to study treatment.

    Measured: Up to 35 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Olaparib in people with Ovarian Cancer, run by Sarah E Taylor at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Aug 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to Next Therapy (time frame: Up to 35 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2024.
