Study Evaluating the Safety and Efficacy of JCARH125 in Subjects With Relapsed and/or Refractory Multiple Myeloma

NCT03430011

Description:

This is an open-label, multicenter, Phase 1/2 study to determine the safety and efficacy of JCARH125, a CAR T-cell product that targets B-cell maturation antigen (BCMA), in adult subjects with relapsed and/or refractory multiple myeloma. The study will include a Phase 1 part to determine the recommended dose of JCARH125 in subjects with relapsed and/or refractory multiple myeloma, followed by a Phase 2 part to further evaluate the safety and efficacy of JCARH125 at the recommended dose.

Eligibility Criteria

        Key Inclusion Criteria:

          1. Diagnosis of multiple myeloma (MM) with relapsed and/or refractory disease.
             Participants must have received at least 3 prior anti-myeloma treatment regimens.
             Participants must have previously received all of the following therapies and must be
             refractory to the last line of therapy prior to entering the study:

               1. Autologous stem cell transplant

               2. A regimen that included an immunomodulatory agent (eg, thalidomide, lenalidomide,
                  pomalidomide) and a proteasome inhibitor (eg, bortezomib, carfilzomib, ixazomib),
                  either alone or in combination

               3. Anti-CD38 (eg, daratumumab) as part of a combination regimen or as a monotherapy

             Subjects who have received prior allogeneic stem cell transplant at least 100 days
             before enrollment with no signs of acute or chronic graft-versus-host disease (GVHD)
             will be considered eligible. Subjects who were not candidates to receive one or more
             of the above treatments (ie, contraindicated) are eligible.

          2. Subjects must have measurable disease.

          3. Subject must be willing to provide fresh bone marrow samples during Screening (and
             prior to study treatment, if required).

          4. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1

          5. Adequate renal, bone marrow, hepatic, pulmonary, and cardiac function

        Exclusion Criteria:

          1. Subjects with known active or history of CNS involvement by malignancy

          2. Subjects with solitary plasmacytoma; active or history of plasma cell leukemia (PCL);
             Waldenstrom's macroglobulinemia; Polyneuropathy, Organomegaly, Endocrinopathy,
             Monoclonal protein, Skin changes (POEMS) syndrome; or symptomatic amyloidosis

          3. Subjects who are considered eligible to receive and have not refused an autologous
             stem cell transplant

          4. History of another primary malignancy that has not been in remission for at least 3
             years. The following are exempt from the 3-year limit: non-melanoma skin cancer,
             curatively treated localized prostate cancer, cervical carcinoma in situ on biopsy or
             a squamous intraepithelial lesion on Pap smear, and in situ breast cancer that has
             been completely resected.

          5. Require systemic immunosuppressive therapies (eg, calcineurin inhibitors,
             methotrexate, mycophenolate, rapamycin, thalidomide, immunosuppressive antibodies such
             as anti-IL-6 or anti-IL-6 receptor [IL-6R])

          6. Prior CAR T-cell or other genetically-modified T-cell therapy

          7. Prior treatment with a BCMA-targeted agent

          8. History or presence of clinically relevant CNS pathology such as epilepsy, seizure,
             paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease,
             cerebellar disease, organic brain syndrome, or psychosis

          9. Untreated or active infection at time of initial screening, at the time of
