SIERRA: A Phase 1b/2 Study of Demcizumab Plus Paclitaxel in Subjects With Platinum Resistant Ovarian, Primary Peritoneal or Fallopian Tube Cancer

This is a Phase 1b/2 study of paclitaxel plus demcizumab in subjects with platinum resistant ovarian, primary peritoneal or fallopian tube cancer.

Study Overview

Status

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

Phase 1b portion was completed; Phase 2 portion was not initiated.

Subjects must not have received prior weekly paclitaxel or more than 3 prior chemotherapy regimens in the Phase 1b portion of the study and more than 2 prior chemotherapy regimens in the Phase 2 portion of the study. Prior to enrollment, subjects will undergo screening to determine study eligibility. In the Phase 1b portion of study, 3 subjects will be treated at each dose level if no dose-limiting toxicities (DLTs) are observed. If 1 of 3 subjects experiences a DLT, that dose level will be expanded to 6 subjects.

If 2 or more subjects experience a DLT, no further subjects will be dosed at that level and 3 additional subjects will be added to the preceding dose cohort unless 6 subjects have already been treated at that dose level. Subjects will be assessed for DLTs from Days 0-28. Dose escalation for newly enrolled subjects, if appropriate, will occur after all subjects in a cohort have completed their Day 28 DLT assessment. After the final patient in the Phase 1b portion of the trial has completed their Day 28 DLT assessment, 50 subjects will be enrolled in the Phase 2 portion of the study and treated with demcizumab at the highest dose level that had < 2 DLTs in the 6 subjects.

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

21 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  1. Subjects must have cytologically or histologically confirmed ovarian, primary peritoneal or fallopian tube cancer.. In addition, subjects must have a tumor that is at least 1 cm in a single dimension and is radiographically apparent on CT, PET-CT or MRI (i.e., RECIST version 1.1 measurable disease).
  2. Subjects must have platinum resistant disease (i.e., which is defined as disease progression in less than 6 months after receiving a minimum of 4 cycles of a platinum containing regimen).
  3. Subjects with the following histologic epithelial cell types are eligible: Serous adenocarcinoma, endometrioid adenocarcinoma, mucinous adenocarcinoma, undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma, transitional cell carcinoma, malignant Brenner's Tumor, or adenocarcinoma N.O.S.
  4. Age >21 years
  5. ECOG performance status <3

Exclusion Criteria:

  1. Subjects receiving any other investigational medicinal product or anti-cancer therapy.
  2. Prior therapy with weekly paclitaxel for recurrent disease (administration of weekly paclitaxel as part of an upfront treatment strategy is acceptable as long as the patient had not progressed while receiving weekly paclitaxel or recurred within 4 months of receiving weekly paclitaxel)
  3. Non-epithelial ovarian carcinoma, including malignant mixed Mullerian tumors.
  4. For the Phase 1b portion of the study, more than 3 prior chemotherapy regimens and for the Phase 2 portion of the study more than 2 prior chemotherapy regimens. Maintenance therapy following induction chemotherapy does not count as a separate regimen. In addition, hormonal therapy (e.g., tamoxifen or an aromatase inhibitor) does not count as a separate regimen.
  5. Prior radiotherapy to the pelvis or abdomen
  6. Subjects receiving heparin, warfarin, or other similar anticoagulants. Note: Subjects may be receiving lowdose aspirin and/or non-steroidal anti-inflammatory agents.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Phase 1b: Dose limiting toxicities (DLT) of demcizumab when combined with weekly paclitaxel in subjects with platinum resistant ovarian, primary peritoneal or fallopian tube cancer
Time Frame: Subjects will be treated and observed for DLT through the end of the first cycle (Days 0-28)
The maximum tolerated dose (MTD) will be determined in patients treated with demcizumab in combination with weekly paclitaxel
Subjects will be treated and observed for DLT through the end of the first cycle (Days 0-28)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pharmacokinetics (PK) of demcizumab when given in combination with weekly paclitaxel
Time Frame: Plasma sample for Pharmacokinetics (PK) analysis to be obtained prior to the demcizumab infusion on Days 0, 14, 56 and 70 and at the end of the demcizumab infusion (prior to paclitaxel infusion) on Days 0 and 56.
