Study of PHE885 in adult patients with relapsed and refractory Multiple Myeloma

Phase 1

• Conditions: Adult participants with relapsed and refractory multiple myeloma who failed 3 or more different prior lines of therapy, including failing an immunomodulatory drug (IMiD), a proteasome inhibitor (PI) and an anti-CD38 (cluster of differentiation 38) monoclonal antibody (mAb), and who have measurable disease at enrollment and documented evidence of progressive disease per IMWG criteria on the last prior therapy. Participants must be refractory to the last line of therapy.; MedDRA version: 21.0Level: LLTClassification code 10028228Term: Multiple myelomaSystem Organ Class: 100000004864; Therapeutic area: Diseases [C] - Cancer [C04]

Recruitment & Eligibility

• Status: Authorised-recruitment may be ongoing or finished
• Sex: All
• Target Recruitment: 100

Inclusion Criteria

1. Written informed consent must be obtained prior to any screening procedures.
2. Participants must be =18 years of age at the time of informed consent form (ICF) signature.
3. Participant has an Eastern Cooperative Oncology Group (ECOG) performance status 0-1 at screening.
4. Participant has a previous diagnosis of MM, based on IMWG definitions.
5. Participants who have failed three or more lines of therapy including failing an IMiD (e.g., lenalidomide or pomalidomide), a proteasome inhibitor (e.g., bortezomib, carfilzomib), and an anti-CD38 agent (e.g., daratumumab, isotuximab) and have documented evidence of disease progression (IMWG criteria).
• A minimum of 51 participants who have failed 3 therapies will be required among the 100 evaluable participants. Enrollment for participants with 4 or more lines of prior therapy will be closed after the 49th participant to meet this eligibility criteria.
6. Must have received = 1 cycle of treatment for each regimen unless deemed refractory to that regiment (i.e. progressive disease as the best response).
7. Must be refractory to the last treatment regimen (defined as progressive disease on or within 60 days measured from last dose of last regimen).
8. Must have measurable disease defined by at least 1 of the following 3 measurements as per IMWG criteria:
• Serum M-protein = 1.0 g/dL OR
• Urine M-protein = 200 mg/24 hours OR
• Serum free light chain (FLC) = 100 mg/L of involved FLC provided sFLC ratio is abnormal
9. The participant is willing and able to adhere to the procedures and treatments outlined in the protocol.
10. Must have a leukapheresis product of non-mobilized cells accepted for manufacturing.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 65
F.1.3 Elderly (>=65 years) yes

Exclusion Criteria

1. Prior administration of a genetically modified cellular product, including prior BCMA CAR-T cell therapy.
2. Participants who have received prior BCMA-directed bi-specific antibodies or anti-BCMA antibody drug conjugate.
3. Hypersensitivity to any product (including its ingredients) to be given to the participant as per the study protocol (e.g., PHE885, tocilizumab and lymphodepleting agents).
4. Prior autologous SCT within 3 months prior to signing informed consent or allogeneic SCT within 3 months prior to signing informed consent.
5. Active Graft-versus-Host Disease (GVHD), grade 2-4 according to the Mount Sinai GvHD International Consortium criteria or requiring systemic treatment.
6. Plasma cell leukemia and other plasmacytoid disorders, non-secretory myeloma without other evidence of measurable disease.
7. POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes).
8. Active CNS involvement by malignancy. Participants whose CNS involvement was treated with resolved symptoms, provided that local treatment was > 4 weeks before enrollment, are eligible.
9. Participants with active neurological auto immune or inflammatory disorders (e.g., Guillain-Barre Syndrome, Amyotrophic Lateral Sclerosis).
10. Participants with Grade = 3 neuropathy, or residual non-hematologic effects of Grade = 2 from previous therapy (excluding alopecia).
11. Chemotherapy, small molecule targeted antineoplastics, or any concomitant anti-cancer therapies (other than protocol allowed LD chemotherapy) within 2 weeks prior to apheresis or prior to PHE885 injection.
12. For participants that received prior antibodies (e.g., daratumumab, isotuximab, elotuzumab) the washout period is 3 weeks prior to apheresis collection.
13. Radiotherapy within 2 weeks prior to enrollment except localized radiation therapy for lytic bone lesions or plasmacytomas.
14. Investigational medicinal product within the 4 weeks prior to screening or within 5-half-lives of the investigational product, whichever is longer. Note: Investigational therapies must not be used at any time while on study until the first progression following PHE885 injection.
15. Participants receiving systemic steroid therapy or other immunosuppressive drugs unless the conditions outlined in the protocol are met.
16. Previous or concurrent malignancy with the following exceptions:
• Adequately treated basal cell or squamous cell carcinoma (adequate wound healing is required prior to study entry)
• In situ carcinoma treated curativel
• A primary malignancy which has been completely resected and in complete remission for = 3 years.
17. Impaired cardiac function or clinically significant cardiac disease, including any of the conditions outlined in the protocol.
18. Inadequate organ function during screening (i.e., within 56 days before the first dose of study treatment) as outlined in the protocol.
19. Presence of active hepatitis B or C as indicated by serology.
