On September 7, 2017 Celgene Corporation (NASDAQ:CELG) reported that the U.S. Food and Drug Administration (FDA) has placed a partial clinical hold on five trials and a full clinical hold on one trial in the Celgene FUSION program (Press release, Celgene, SEP 7, 2017, View Source [SID1234520404]). The trials are testing IMFINZI (durvalumab), an anti-PD-L1 antibody, in combination with immunomodulatory and chemotherapy agents in blood cancers such as multiple myeloma, chronic lymphocytic leukemia and lymphoma.

The decision by the FDA was based on risks identified in other trials for an anti-PD-1 antibody, pembrolizumab, in patients with multiple myeloma in combination with immunomodulatory agents. In the FUSION program, the Company has not discerned, at this time, an imbalance in the risk benefit profile; however, the clinical holds allow for additional information to be collected to further understand the risk benefit profile of the program.
Patients enrolled in the trials on partial clinical hold who are receiving clinical benefit from treatment as determined by the investigator, may remain on treatment. Patients enrolled in the trial on full clinical hold will be discontinued from treatment. No new patients will be enrolled into the listed trials.
The trials placed on partial clinical hold are:
MEDI4736-MM-001: A Phase IB Multicenter, Open-Label Study to Determine the Recommended Dose and Regimen of Durvalumab Either as Monotherapy or in Combination with Pomalidomide with or without Low-Dose Dexamethasone in Subjects with Relapsed and Refractory Multiple Myeloma
MEDI4736-MM-003: A Phase II, Multicenter, Open-label, Study to Determine the Safety and Efficacy for the Combination of Durvalumab and Daratumumab in Subjects with Relapsed and Refractory Multiple Myeloma
MEDI4736-MM-005: A Phase II, Multicenter, Single-Arm, Study to Determine the Efficacy for the Combination of Durvalumab Plus Daratumumab in Subjects with Relapsed and Refractory Multiple Myeloma That Have Progressed While on Current Treatment Regimen Containing Daratumumab
MEDI4736-NHL-001: A Phase I/II, Open-label, Multi-center Study to Assess the Safety and Tolerability of Durvalumab as Monotherapy and in Combination Therapy in Subjects with Lymphoma or Chronic Lymphocytic Leukemia. The only arm in this trial for which enrollment is suspended is the arm with the durvalumab, REVLIMID and rituximab combination.
MEDI4736-DLBCL-001: A Phase II, Open-label, Multicenter Study to Evaluate the Safety and Clinical Activity of Durvalumab in Combination with Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisone (R-CHOP) or with Lenalidomide Plus R-CHOP (R2 CHOP) in Subjects with Previously Untreated, High Risk Diffuse Large B Cell Lymphoma
The trial placed on full clinical hold is:
MEDI4736-MM-002: A Phase Ib Multicenter, Open-label Study to Determine the Recommended Dose and Regimen of Durvalumab in Combination with Lenalidomide with and without Low-dose Dexamethasone in Subjects with Newly Diagnosed Multiple Myeloma
The trials that will continue to enroll are:
MEDI4736-MDS-001: A Randomized, Multicenter, Open-label, Phase II Study Evaluating the Efficacy and Safety of Azacitidine Subcutaneous in Combination with Durvalumab in Previously Untreated Subjects with Higher-Risk Myelodysplastic Syndromes or in Elderly ( > = 65 Years) Acute Myeloid Leukemia Subjects Not Eligible for Hematopoietic Stem Cell Transplantation
CC-486-MDS-006: A Phase II, International, Multicenter, Randomized, Open-label, Parallel Group to Evaluate the Efficacy and Safety of CC-486 Alone in Combination with Durvalumab in Subjects with Myelodysplastic Syndromes Who Fail to Achieve an Objective Response to Treatment with Azacitidine for Injection or Decitabine
In April 2015, Celgene entered into a strategic collaboration with MedImmune, the global biologics research and development arm of AstraZeneca, to develop and commercialize IMFINZI for hematologic malignancies. The use of IMFINZI in combination with other agents for the treatment of patients with hematologic malignancies is not approved by the FDA, and the safety and efficacy of those combinations have not been established.
