Safety and Efficacy of ALLO-715 BCMA Allogenic CAR T Cells in in Adults With Relapsed or Refractory Multiple Myeloma (UNIVERSAL)



The purpose of the UNIVERSAL study is to assess the safety, efficacy, cell kinetics, and immunogenicity of ALLO-715 with or without Nirogacestat in adults with relapsed or refractory multiple myeloma after a lymphodepletion regimen of ALLO-647 in combination with fludarabine and/or cyclophosphamide, or ALLO-647 alone.

Am I Eligible?

The following criteria is a partial list of reasons why patients may or may not be eligible to participate in this clinical trial. Further evaluation with a medical professional will be required to determine full eligibility.

The following criteria is provided for health care professionals.

Inclusion Criteria:

  • Documented diagnosis of relapsed/refractory multiple myeloma (MM) with measurable disease (serum, urine, or free light chain [FLC]) per International Myeloma Working Group (IMWG) criteria
  • At least 3 prior lines of MM therapy, including a proteasome inhibitor, immunomodulatory agent, and anti-CD38 antibody (unless contraindicated), and refractory to the last treatment line.
  • Eastern Cooperative Oncology Group (ECOG) 0 or 1
  • Absence of donor (product)-specific anti-HLA antibodies
  • Adequate hematologic, renal, hepatic, pulmonary, and cardiac function

Exclusion Criteria:

  • Current or history of Central Nervous System (CNS) involvement of myeloma or plasma cell leukemia
  • Clinically significant CNS disorder
  • Current or history of thyroid disorder
  • Autologous stem cell transplant within the last 6 weeks, or any allogeneic stem cell transplant
  • Prior treatment with anti-BCMA therapy, any gene therapy, any genetically modified cell therapy, or adoptive T cell therapy
  • History of HIV infection or acute or chronic active hepatitis B or C infection
  • Patients unwilling to participate in an extended safety monitoring period

Additional Exclusion Criteria for Nirogacestat plus ALLO-715 Cohorts

  • Inability to swallow tablets
  • Subject has known malabsorption syndrome or preexisting gastrointestinal conditions that may impair absorption of nirogacestat
  • Use of strong/moderate CYP3A4 inhibitors, and strong CYP3A4 inducers within 14 days before starting nirogacestat.
  • Use of concomitant medications that are known to prolong the QT/QTcF interval

Published Results

Allogene Therapeutics Reports Positive Results from Phase 1 UNIVERSAL Study of Single Dose ALLO-715 AlloCAR T™ Cell Therapy in Relapsed/Refractory Multiple Myeloma at the 63rd American Society of Hematology Annual Meeting

December 13, 2021

As of the October 14, 2021 data cutoff, 48 patients were enrolled with 43 patients evaluable for safety and efficacy. Patients were refractory to their last line of myeloma therapy, had a median of five prior lines of therapy, and 42% were penta-refractory meaning the disease has ultimately become nonresponsive to other approved therapies. Five patients became ineligible for treatment due to rapidly progressing disease. The median time from enrollment to the start of therapy was five days.

The Phase 1 UNIVERSAL trial evaluated lymphodepletion followed by ALLO-715 at one of four dose levels (DL1=40M cells, DL2=160M cells, DL3=320M cells, DL4 = 480M cells) and two LD regimens (FCA: fludarabine, cyclophosphamide and ALLO-647 or CA: cyclophosphamide and ALLO-647 only). The updated presentation primarily focuses on the optimized DL3 cell dose and FCA lymphodepletion.

The higher CAR T cell doses were associated with an increased response rate and greater AlloCAR T cell expansion. In the DL3 cohort which was selected for cohort expansion, the overall response rate (ORR) increased from 60% reported at ASH 2020 to 71% with 46% of patients achieving a very good partial response (VGPR) or better (VGPR+) up from 40%. VGPR+ is defined as a stringent complete response (sCR), complete response (CR) or VGPR. Of the patients who achieved VGPR+, 92% were Minimal Residual Disease (MRD) negative.

As of the data cutoff, the overall median follow-up for efficacy was 3.8 months. The median duration of response is 8.3 months, with nine patients remaining in ongoing response at the time of the data cut-off. The longest ongoing response after cell infusion is 12 months. Results showed that soluble BCMA levels were 10 times lower in responders at Day 28, suggesting soluble BCMA suppression is associated with response.

Of the 43 patients evaluable for safety, there was no graft-versus-host-disease (GvHD). Grade 1 and 2 cytokine release syndrome (CRS) was reported in 23 patients (53%) and was manageable with standard therapies. In this heavily pre-treated patient population, infection occurred in 54% of patients, which included three Grade 5 infections, two of which were previously reported. Grade 3+ neutropenia occurred in 70% of patients. Six patients (14%) experienced adverse events of low-grade neurotoxicity, which was reversible. Use of tocilizumab and steroids was infrequent (23% and 14%, respectively).

Off-the-Shelf CAR Therapy Shows Early Promise in Multiple Myeloma

December 05, 2020

ALLO-715, an off-the-shelf chimeric antigen receptor (CAR) T-cell therapy that targets B-cell maturation antigen (BCMA), elicited responses in heavily pretreated patients with relapsed/refractory multiple myeloma in early findings from a first-in-human study presented at the 2020 ASH Meeting.

The therapy generated responses in 6 of 10 patients (60%), including a very good partial-plus response (VGPR+) in 4 patients (40%), who were treated with ALLO-715 at a dose of 320 x 106 CAR cells plus a lymphodepleting regimen that included ALLO-647, an anti-CD52 monoclonal antibody, during the ongoing phase 1 UNIVERSAL study (NCT04093596).
