Linvoseltamab Added as Preferred Agent in Newest MM Practice Guidelines

News
Article

On July 2, linvoseltamab-gcpt (Lynozyfic; Regeneron) received an accelerated approval from the FDA in relapsed/refractory multiple myeloma (MM), and the most recent update to the National Comprehensive Cancer Network guidelines for MM has added the BCMA-targeted bispecific antibody as a preferred treatment option.

When NCCN Clinical Practice Guidelines Version 2.2026 Multiple Myeloma was released on July 16,1 a new preferred treatment option had been added for previously treated disease. Linvoseltamab-gcpt (Lynozyfic; Regeneron) is now recommended and preferred by the National Comprehensive Cancer Network after at least 4 prior lines of therapy, which include an anti-CD38 monoclonal antibody, a proteasome inhibitor (PI), and an immunomodulatory agent. It is also now 1 of 4 bispecific antibodies considered preferred agents in the guidelines, along with teclistamab-cqyv (Tecvayli; Janssen), elranatamab-bccm (Elrexfio; Pfizer), and talquetamab-tgvs (Talvey; Johnson & Johnson), after at least 4 prior lines of therapy.

The bispecific T-cell engager antibody, which targets B-cell maturation antigen (BCMA) on MM cells and CD3 on T cells, received an accelerated approval from the FDA on July 2 following positive results seen for response rate and durability of response in the phase 1/2 LINKER-MM1 trial (NCT03761108).2 In the trial, 70% of patients achieved an objective response rate, 45% achieved a complete response (CR), and the median duration of response was not reached (95% CI, 12 months–not estimable). The approval made it the first BCMAXCD3 bispecific antibody to have biweekly dosing starting at week 14,3 as well as the third BCMA-targeted bispecific antibody to enter the US market, after teclistamab and elranatamab.4 It also follows 2024 expectations that the treatment would be added to the guidelines for use in patients with relapsed/refractory MM after 3 or more lines of treatment5 and comes close to a year after Regeneron received a complete response letter due to issues at a manufacturing plant.6

Linvoseltamab was previously approved by the European Medicines Agency on April 28, also based on LINKER-MM1 results, but for patients with relapsed/refractory MM who have failed at least 3 prior lines of therapy—also an anti-CD38 monoclonal antibody, a PI, and an immunomodulatory agent.7

“When you have more than 1 drug approved, there is no monopoly,” said Sundar Jagannath, MBBS, professor of medicine at the Icahn School of Medicine at Mount Sinai and LINKER-MM1 trial investigator, in an interview with The American Journal of Managed Care®. “It allows the market to play off, as you have 3 different [B-cell maturation antigen] bispecifics. That's also good for the patients, good for the community.”8

Another significant update to the guidelines comprises revised response criteria for MM, based on new criteria from the International Myeloma Working Group1:

  • For minimal residual disease (MRD), there are new criteria for sustained MRD-negative, flow MRD-negative, sequencing MRD-negative, and imaging plus MRD-negative statuses
  • For standard response, criteria for the following were all updated: stringent CR, CR, very good partial response (PR), PR, minimal response, stable disease, progressive disease, clinical relapse, relapse from CR, and relapse from MRD-negative status

Per the guidelines, each of these “response categories require 2 consecutive assessments made any time before starting any new therapy.”1 The exception is MRD, in which evaluations are “recommended” after induction, high-dose therapy/autologous hematopoietic stem cell transplant (aHSCT), consolidation, and maintenance.

A new subsection also has been added to the guidelines: “Considerations for Special Populations.” Within the section are recommendations for frailty assessments in older adults and for equitable care in Black/African American individuals, highlighted by details on how the biology of their myeloma differs compared with other populations—they are less likely to have certain high-risk mutations but more likely to have chromosome 14 translocations such as t(11;14), t(14;16), and t(14;20) vs White individuals—and that absent disparate use of novel therapeutics or aHSCT, they potentially have better median overall survival.

There are also updates included in Version 2.2026 that cover initial diagnostic workup and clinical findings, primary treatment and follow-up/surveillance for asymptomatic smoldering myeloma and symptomatic MM, MM with central nervous system disease (another new section), response after primary therapy, disease staging and risk stratification, supportive care, imaging for follow-up, and follow-up surveillance.
