About this study

Official title: A Phase 1b/2 Randomized, Controlled Study of AVB-S6-500 in Combination With Pegylated Liposomal Doxorubicin (PLD) or Paclitaxel (Pac) in Patients With Platinum-resistant Recurrent Ovarian Cancer

This is a Phase 1b/2 study of AVB-S6-500 in combination with pegylated liposomal doxorubicin (PLD) or paclitaxel (Pac) in patients with platinum resistant recurrent ovarian cancer. The phase 1b portion of the study is open label and patients will receive either AVB-S6-500+PLD or AVB-S6-500+ Pac. The Phase 2 portion of the study is randomized, double-blind, placebo-controlled study to compare efficacy and tolerability of AVB-S6-500 in combination with PLD or Pac versus placebo plus PLD or Pac.

Read the detailed description

While this study was planned as two-part study consisting of a Phase 1b and a Phase 2 portion, the sponsor decided not to proceed with the Phase 2 portion.

The Phase 1b portion of the study was a multicenter, 2-group, open-label design to evaluate the safety and tolerability of AVB-S6-500 combined with PLD or Pac in subjects with platinum-resistant recurrent ovarian cancer. The decision to enroll in the Phase 2 portion of the study was to be driven by the recommendation of a safe and tolerable dose of AVB-S6-500 in combination with each chemotherapy backbone; however, enrollment into the Phase 2 portion was not initiated per Sponsor decision. Given that sufficient data were obtained in the Phase 1b portion AVB-S6-500 + Pac group, the decision was made to pursue a randomized Phase 3 to further study the benefit of this combination versus paclitaxel alone in patients with platinum resistant ovarian cancer.

What is being measured

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

  1. Incidence of Adverse Events (AEs)

    Measured by the number of patients with AEs in Phase 1 portion of the study.

    Measured: 6 months

  2. Anti-tumor activity of AVB-S6-500 in combination with PLD

    Measured by progression free survival (PFS) in patients receiving AVB-S6-500+PLD versus patients receiving Placebo+PLD in Phase 2 portion of the study.

    Measured: 18 months

  3. Anti-tumor activity of AVB-S6-500 in combination with Pac

    Measured by progression free survival (PFS) in patients receiving AVB-S6-500+ Pac versus patients receiving Placebo+Pac in Phase 2 portion of the study.

    Measured: 18 months

Secondary outcomes (12)
  1. Pharmacokinetics: AUC

    Area under the AVB-S6-500 concentration-time curve.

    Measured: 18 months

  2. Pharmacokinetics: Cmax

    Maximum observed AVB-S6-500 concentration.

    Measured: 18 months

  3. Pharmacokinetics: Tmax

    Time of maximum observed AVB-S6-500 concentration.

    Measured: 18 months

  4. Pharmacokinetics: t1/2

    Apparent terminal half-life of AVB-S6-500.

    Measured: 18 months

  5. Pharmacodynamic marker assessment

    Change from the baseline in GAS6 serum levels.

    Measured: 18 months

  6. Anti-drug antibody (ADA) titers

    Change from baseline in ADA titer.

    Measured: 18 months

  7. Objective response rate

    Proportion of subjects who have a partial or complete response to therapy relative to baseline as assessed per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as well as Gynecologic Cancer Intergroup (GCIG) cancer antigen (CA)-125 criteria.

    Measured: 18 months

  8. Disease control rate

    Proportion of subjects who have a complete or partial response to therapy or maintain stable disease.

    Measured: 18 months

  9. Duration of response (DOR)

    Measured from the date of partial or complete response to therapy until the cancer progresses.

    Measured: 18 months

  10. Overall survival

    Time following the treatment until death.

    Measured: 30 months

  11. CA-125 response rate

    Proportion of subjects with a minimum 50% reduction in CA-125 serum levels lasting for 28 days relative to baseline CA-125 serum levels.

    Measured: 18 months

  12. Quality of Life(QOL)

    Subject QOL will be assessed every 8 weeks during treatment using the Functional Assessment Of Cancer Therapy - Ovarian Cancer (FACT-O) questionnaire, which consists of 4 subscales: physical well-being (7 questions), social/family well-being (7 questions), emotional well-being (6 questions), and functional well-being (7 questions), and 12 additional concerns specific to ovarian cancer. All items are rated on a 5 point scale with 0 "not at all" and 4 "very much". The scoring algorithm allows for eight summary scales: the four core well-being subscales, a subtotal of the 27 core items, a subtotal of the 12 ovarian-specific additional concerns, a grand total of the 39 items, and a trial outcome index (sum of the 17 physical and functional wellbeing items plus the 12 ovarian-specific items).

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AVB-S6-500, Paclitaxel (Pac) and Pegylated liposomal doxorubicin (PLD) in people with Ovarian Cancer, run by Aravive, Inc. at 16 sites 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 9 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: finished, as of the sponsor's last update on 13 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Incidence of Adverse Events (AEs) (time frame: 6 months). The study lists 3 primary outcomes in all. 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 13 Feb 2023.
