1 Recommendations

1.1

Elranatamab is recommended with managed access as an option for treating relapsed and refractory multiple myeloma in adults after 3 or more lines of treatment (including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody) when the myeloma has progressed on the last treatment. It is only recommended if:

  • pomalidomide plus dexamethasone would otherwise be offered, and

  • the conditions in the managed access agreement for elranatamab are followed.

1.2

This recommendation is not intended to affect treatment with elranatamab that was started in the NHS before this guidance was published. People having treatment outside this recommendation may continue without change to the funding arrangements in place for them before this guidance was published, until they and their NHS healthcare professional consider it appropriate to stop.

Why the committee made these recommendations:

The treatment most commonly used for relapsed and refractory multiple myeloma after 3 lines of treatment (including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody) is pomalidomide plus dexamethasone. For this evaluation, the company asked for elranatamab to only be considered as an alternative to pomalidomide plus dexamethasone. This does not include everyone who it is licensed for.

Evidence from a clinical trial for elranatamab is promising, but it was not compared with other treatments and the trial is still ongoing. So, the effectiveness of elranatamab and its long-term benefits are uncertain. The results from this trial were used for an indirect comparison with pomalidomide plus dexamethasone. It suggests that elranatamab could increase how long people have before their condition gets worse and how long they live compared with pomalidomide plus dexamethasone. But the results are uncertain because it was based on the uncertain elranatamab trial data.

Because of the uncertainty in the long-term benefits of elranatamab, and in the long-term use of intravenous immunoglobulin in people having elranatamab, the cost-effectiveness estimates are also highly uncertain. So, it cannot be recommended for routine use in the NHS.

Elranatamab could be cost effective if further evidence shows that people live longer with treatment. Longer-term evidence from the trial and NHS practice could help address the remaining uncertainties. So, elranatamab is recommended for use with managed access if it is used only as an alternative to pomalidomide plus dexamethasone.
