BCMA-directed CAR-T Cell Therapy in Adult Patients With Relapsed and/or Refractory Multiple Myeloma PHE885

What's the purpose of this trial?

This is a first-in-human study to evaluate the feasibility, safety and preliminary antitumor efficacy of autologous T cells genetically engineered with a novel B-cell Maturation Antigen (BCMA)-specific chimeric antigen receptor (CAR) and manufactured with a new process. CAR-T cells will be investigated as a single agent in relapsed/refractory multiple myeloma.

This trial is currently open and accepting patients.


What will happen during the trial?

You may be able to join this trial if you:

The following criteria is a partial list of reasons why patients may be eligible to participate in this clinical trial. Further evaluation with a medical professional is required.

Inclusion Criteria:

  • Subjects with MM who are relapsed and/or refractory to at least 2 prior treatment regimens, including an IMiD (e.g. lenalidomide or pomalidomide), a proteasome inhibitor (e.g. bortezomib, carfilzomib), and an approved anti-CD38 antibody (e.g. daratumumab), if available, and have documented evidence of disease progression (IMWG criteria)
  • Measurable disease as defined by the protocol
  • ECOG performance status that is either 0 or 1 at screening
  • Adequate hematological values
  • Must have a leukapheresis material of non-mobilized cells accepted for manufacturing

Exclusion Criteria:

  • Prior administration of a genetically modified cellular product including prior BCMA CAR-T therapy. Patients who have received prior BCMA-directed bi-specific antibodies or antibody-drug conjugates (ADC) are not excluded.
  • Autologous HSCT within 6 weeks prior to enrollment or any prior history of allogeneic hematopoietic stem cell transplant (HSCT)
  • Chemotherapy or any concomitant anti-cancer therapies (other than protocol prescribed lymphodepletion (LD) chemotherapy) within 2 weeks prior to apheresis
  • Treatment with small molecule targeted antineoplastics within 2 weeks of apheresis collection or 5 half-lives whichever is shorter
  • Have received antibodies or immunotherapies (other than daratumumab) within 4 weeks prior to apheresis collection. Daratumumab within 3 weeks prior to apheresis collection.

Novartis announces T-Charge™, next-generation CAR-T platform with first-in-human data at ASH 2021

December 13, 2021

PHE885, an investigational, autologous BCMA-directed CAR-T cell therapy developed using the T-Charge platform, demonstrated promising results in patients with relapsed or refractory multiple myeloma in a first-in-human Phase I, multicenter, dose-escalation study. Fifteen patients were evaluated for efficacy and safety and the fixed doses received were 2.5×106 (n=4), 5×106 (n=10) and 14.3×106 CAR-T cells (n=1). Although the follow-up period was brief, PHE885 shows encouraging initial clinical activity with a best overall response of 100% for patients receiving the 5×106 or 14.3×106 CAR-T cell dose, with responses deepening over time. With a median follow-up of 3.5 months, eight of 15 patients had ongoing responses at the time of data cutoff. Of the evaluable patients at three months post administration, 34% (2/6) were MRD-negative by next-generation sequencing (NGS) at 10-6; 43% (3/7) were MRD-negative at 10-5.

All patients experienced CRS with two patients experiencing grade ≥3 CRS. No patients experienced grade 4 or 5 CRS. All neurotoxicity events (n=4) were nonserious, grade 1-2, reversible, and temporally associated with CRS.
