NCT05617755

Brief Summary

This is a multi-center, open-label phase 1 dose escalation trial that uses a modified 3+3 design to identify a recommended phase 2 dose (RP2D) of AB-1015 cell product. Backfill cohorts will enroll additional subjects at doses deemed to be safe for a total enrollment of up to 12 subjects per each backfill cohort on the protocol.

Outcome Measures

Primary Outcomes (2)

  • Incidence of adverse events and dose limiting toxicities (DLTs)

    Toxicity grading will be evaluated according to the Cancer Therapy Evaluation Program Common Terminology Criteria for Adverse Events version 5.0 and monitoring of adverse events. Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) events will be graded according to the criteria outlined in the protocol.

    Up to 2 years post treatment

  • Maximal tolerated dose of AB-1015

    Will be determined by a 3x3 dose escalation study

    Up to 21 days

Secondary Outcomes (3)

  • Number of AB-1015 cells

    Up to 1 year post treatment

  • Evidence of anti-tumor activity

    Up to 2 years post treatment

  • Co-expression of ALPG and MSLN targets on tumor cells

    Up to 2 years post treatment

Study Arms (1)

AB-1015

EXPERIMENTAL

Patients receive fludarabine and cyclophosphamide intravenously on days -5 to -3. Patients receive a single dose of AB-1015 intravenously on day 0.

Biological: AB-1015

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Recurrent, advanced, platinum resistant ovarian, fallopian tube, and primary peritoneal cancer and must have a histological diagnosis of a high-grade serous histology.
  • a) Platinum resistant disease is defined as progression of disease within six months of platinum regimen.
  • Doubling of cancer antigen 125 (CA-125) level on 2 successive measurements may be considered as meeting the definition of disease progression
  • b) Have received at least 2 lines of prior therapy including a platinum-based regimen if eligible and a poly-ADP ribose polymerase (PARP) inhibitor if BRCA1/2 mutated. No more than 3 lines of prior therapy for the treatment of platinum resistant disease is permitted.
  • Adequate organ function as per protocol definitions.
  • Eastern Cooperative Oncology Group (ECOG) performance status score 0 or 1.
  • Evaluable disease (dose escalation cohorts) or measurable disease (backfill cohorts) at time of enrollment as per protocol definitions.
  • Negative pregnancy test for women of childbearing potential. Women of non-childbearing potential are those who have been surgically sterilized, have medically confirmed ovarian failure, or have not had menses within the past 12 months.

You may not qualify if:

  • Cytotoxic chemotherapy within 14 days of time of cell collection.
  • Cytotoxic chemotherapy within 14 days of starting of conditioning chemotherapy.
  • New York Heart Association functional class II-IV cardiovascular disability
  • Clinically significant pericardial effusion
  • Pleural or peritoneal effusion that requires drainage for symptom management within 28 days of screening.
  • Active autoimmune disease requiring immunosuppressive therapy or uncontrolled with treatment.
  • Untreated brain metastasis.
  • Subjects unwilling to participate in an extended safety monitoring period.
