May 15, 2024 updated by: Tracon Pharmaceuticals Inc.

ENVASARC: A Pivotal Trial Of Envafolimab, And Envafolimab In Combination With Ipilimumab, In Patients With Advanced Or Metastatic Undifferentiated Pleomorphic Sarcoma Or Myxofibrosarcoma Who Have Progressed On Prior Chemotherapy

This is a multicenter open-label, randomized, non-comparative, parallel cohort pivotal study of treatment with envafolimab (cohort A and C) or envafolimab combined with ipilimumab (cohort B and D) in patients with locally advanced, unresectable or metastatic undifferentiated pleomorphic sarcoma (UPS)/myxofibrosarcoma (MFS) who have progressed on one or two lines of chemotherapy.

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

Detailed Description

This is a multicenter open-label, randomized, non-comparative, parallel cohort pivotal study of treatment with envafolimab (cohort A and C) or envafolimab combined with ipilimumab (cohort B and D) in patients with locally advanced, unresectable or metastatic UPS/MFS who have progressed on one or two lines of chemotherapy. Patients were previously assigned at random into one of two cohorts: cohort A of 80 patients who received single agent envafolimab (300 mg every 3 weeks by subcutaneous (SC) injection) or cohort B of 80 patients who received envafolimab (300 mg every 3 weeks by SC injection) in combination with ipilimumab (1 mg/kg every 3 weeks intravenously for four doses). Following amendment #3, patients will be assigned at random into one of two cohorts: cohort C of 80 patients who will receive single agent envafolimab (600 mg every 3 weeks by subcutaneous (SC) injection) or cohort D of 80 patients who will receive envafolimab 600 mg every 3 weeks by SC injection) in combination with ipilimumab (1 mg/kg every 3 weeks intravenously for four doses). Following amendment #4, enrollment into cohort D was terminated and no further interim analyses will be conducted on this cohort.

Phase

Phase

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

8 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Histologically confirmed locally advanced or metastatic undifferentiated pleomorphic sarcoma (UPS) or grade ≥ 2 myxofibrosarcoma (MFS)
  • Documented progression following systemic chemotherapy
  • At least one measurable lesion
  • Eastern Cooperative Oncology Group performance status of 0 or 1
  • Adequate hematologic and organ function

Exclusion Criteria:

  • More than two prior lines of chemotherapy for UPS/MFS
  • Prior immune checkpoint inhibitor or immunomodulatory therapy
