Bristol Myers Squibb BMY announced positive phase II results from the registrational QUINTESSENTIAL study evaluating arlocabtagene autoleucel (arlo-cel; BMS-986393) in heavily pretreated patients with relapsed and refractory multiple myeloma.
Arlo-cel is a potential first-in-class autologous G protein-coupled receptor class C group 5 member D (GPRC5D)-directed CAR T cell therapy.
The results are encouraging because arlo-cel targets GPRC5D, giving BMY an opportunity to treat patients already exposed to BCMA-directed therapies. The study met its primary endpoint, demonstrating a statistically significant and clinically meaningful overall response rate (ORR) in quadruple-class exposed patients who had received at least four prior lines of therapy. The trial also met key secondary endpoints, including complete response rate (CRR), as well as ORR and CRR in patients who had received three or more prior lines of treatment.
Quadruple-class exposure consists of those who have been treated with an immunomodulatory inhibitor, a proteasome inhibitor, an anti-CD38 therapy and a BCMA-targeted therapy.
The findings are particularly relevant as treatment options for heavily pretreated multiple myeloma remain limited. As patients increasingly become resistant to multiple drug classes earlier in the treatment journey, therapies that work through alternative targets could have significant commercial potential.
Arlo-cel is also potentially differentiated as a single-infusion autologous CAR T therapy targeting GPRC5D, providing BMY with another potential growth opportunity in cell therapy and multiple myeloma.
Importantly, GPRC5D expression is independent of BCMA expression and can be maintained following prior BCMA-directed treatment, supporting the rationale for using arlo-cel after BCMA therapies.
While arlo-cel is still investigational, and additional clinical and regulatory milestones will be needed before its commercial opportunity can be fully assessed, the positive data potentially strengthens the company’s long-term multiple myeloma pipeline and could help diversify growth beyond its established portfolio.
BMY already has CAR T cell therapy Breyanzi in its portfolio. Breyanzi is a CD19-directed CAR T cell therapy with a 4-1BB costimulatory domain, which enhances the expansion and persistence of the CAR T cells. It is approved for multiple blood cancers.
Last month, the FDA granted accelerated approval to iberdomide in combination with daratumumab and hyaluronidase-fihj and dexamethasone (ZDd).
The regimen, approved under the brand name Zenbexus, is approved for the treatment of adults with multiple myeloma who have received at least one prior line of therapy.
Zenbexus is the first FDA-approved cereblon E3 ligase modulator, representing a novel class of cereblon-modulating protein degraders developed to treat multiple myeloma.
BMY is striving to broaden its portfolio to achieve sustained top-tier growth and maximize long-term value. The approval of new drugs brings an incremental stream of revenues to the company.
BMY Faces Competition for the CAR T Cell Therapy
Breyanzi faces competition from Gilead Sciences’ GILD Yescarta for its approved indications.
Gilead’s Yescarta is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adult patients with LBCL that is refractory to first-line chemoimmunotherapy or relapses within 12 months of first-line chemoimmunotherapy. It is also approved for adult patients with relapsed or refractory LBCL after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, high-grade B-cell lymphoma and DLBCL arising from FL.
GILD has another CAR T cell therapy in its franchise, Tecartus.
Another approved CAR T therapy is Novartis’ NVS Kymriah, which is approved for acute lymphoblastic leukemia that is either relapsing or refractory. It is also used in patients with LBCL or FL, two types of non-Hodgkin lymphoma, who have relapsed or are refractory after undergoing at least two other kinds of treatment.
NVS’ Kymriah recorded sales of $169 million in the first half of 2026, down 15% from the year-ago period due to competitive pressure.
Per a Wall Street Journal article, Novartis paused eight clinical studies on investigational CAR T cell therapy, rap-cel, in late August, after three patients died.
