Overview

Study Title

A Phase 1/1b Safety Study of PRGN-3006 Adoptive Cellular Therapy in Patients with Relapsed or Refractory CD33-Positive Acute Myeloid Leukemia and Higher Risk Myelodysplastic Syndrome

Summary

Objective

Primary objective: To identify and evaluate the safety and MTD of PRGN-3006 T cells in patients with relapsed or refractory AML or higher risk MDS.

Treatments

Therapies

Medications

PRGN-3006 T Cell (); cyclophosphamide (); cytoxan (cyclophosphamide); fludarabine (Fludarabine phosphate)

Inclusion Criteria

Participants must be diagnosed with either relapsed or refractory CD33+ AML or higher risk MDS/chronic myelomonocytic leukemia (CMML)

Absolute lymphocyte count ≥ 0.2 k/μL.

Karnofsky performance status score ≥60%.

Life expectancy ≥ 12 weeks from the time of enrollment.

Pretreatment calculated or measured creatinine clearance (absolute value) of ≥ 40 mL/minute or Cr > 2x upper limit of normal (ULN).

Serum bilirubin ≤ 2.0 mg/dL or total bilirubin ≤ 3.0 x IULN with direct bilirubin within normal range in participants with well documented Gilbert's syndrome or hemolysis or who require regular blood transfusions

Alanine aminotransferase (AST) and aspartate aminotransferase (ALT) > Ejection fraction measured by echocardiogram (ECHO) or multi gated acquisition scan (MUGA) > 45%.

Participant does not require supplemental oxygen or mechanical ventilation AND has an oxygen saturation by pulse oximetry of ≥ 92% or higher on room air.

Negative serum pregnancy test. Note: Women of child-bearing potential and men must agree to use adequate contraception prior to study entry and for at least 1 year following study treatment (T cell infusion); should a woman participant or female partner of a male participant become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately.

Participant has a matched bone marrow donor and is otherwise able to receive a bone marrow transplant (dose escalation part only)

Participants who have undergone allo-SCT are eligible if they are at least 3 months post SCT, have relapsed AML/MDS as defined above, are not on treatment or prophylaxis for GVHD for at least 6 weeks before administration of CAR T cells, and have no active GVHD.

All participants must have the ability to understand and willingness to sign a written informed consent.

Exclusion Criteria

Diagnosis of acute promyelocytic leukemia (APL M3): t(15;17)(q22;q12); (promyelocytic leukemia [PML]/retinoic acid receptor [RAR] alpha [a]) and variants excluded.

Participants with extramedullary disease as their sole site of relapsed AML.

Known central nervous system (CNS) leukemic involvement that is refractory to intrathecal chemotherapy and/or cranio-spinal radiation; participants with a history of CNS disease that have been effectively treated to complete remission ( i.e. no blasts in cerebrospinal fluid [CSF] by cytology and flow cytometry) will be eligible.

Prior treatment with investigational CAR T therapy for any disease.

Participants enrolled in another investigational therapy protocol for AML within 14 days or 5 half-lives of enrollment, whichever is shorter.

Ongoing uncontrolled serious infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, poorly controlled pulmonary disease or psychiatric illness/social situations that would limit compliance with study requirements.

Human immunodeficiency virus (HIV) seropositivity, or active hepatitis B or C infection based on testing performed within 28 days of enrollment.

Participants requiring agents other than hydroxyurea to control blast counts within 14 days of study enrollment.

Participants with presence of other active malignancy within 1 year of study entry;

Participants with adequately resected basal or squamous cell carcinoma of the skin, or adequately resected carcinoma in situ (e.g. cervix) may enroll irrespective of the time of diagnosis.

Pregnant and lactating women are excluded from this study

History of allergic reactions attributed to compounds of similar chemical or biological composition to cetuximab (anti-EGFR).

Active autoimmune disease requiring systemic immunosuppressive therapy (i.e. >10mg of prednisone daily or equivalent).

Participant, who in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study.
