Protocols & Players
ELREXFIO: By the Book
Name that BsAb
KOLs: Called It or Missed It?
100

This recent US-approved 2L+ regimen combines a BCMA-directed BsAb with an anti-CD38 mAb

What is teclistamab and daratumumab (MajesTEC-3)

100

Unlike the USPI, which specifies 4 prior lines, the SmPC requires ELREXFIO be used after this

What is 3 prior therapies

100

This BsAb is increasingly used as a bridging strategy to CAR T-cell therapy

What is talquetamab

100

According to KOL insights, this type of 2L patient may be preferred for BsAb monotherapy

What is anti-CD38-refractory patients (also accepted: frail patients)

200

This is the control arm in MagnetisMM-5

What is DPd
200

After 44 months of follow-up with ELREXFIO, this efficacy endpoint has still not been reached

What is duration of response

200

As of May 2026, median PFS has not yet been reached for this BsAb

What is linvoseltamab

200

In addition to concerns with infection risk, being confined to patients who are “ultra frail” or have significant comorbidities, and T-cell exhaustion, KOLs have identified this as a key perceived weakness of BsAb monotherapy

What is long-term durability

400

Compared with MagnetisMM-32, this is how the patient population differs in MagnetisMM-5

MagnetisMM-5: ≥1 prior LOT, including lenalidomide and a PI

MagnetisMM-32: 1-4 prior LOTs, including an anti-CD38 mAb and lenalidomide

400

Per the ELREXFIO SmPC, patients may switch to monthly dosing after at least this many weeks of treatment on an every-2-week dosing schedule

What is 24 weeks

400

Apart from elranatamab, this BsAb/BsAbs is/are being evaluated as a monotherapy in 2L+ MM

What is teclistamab and linvoseltamab

400

Some HCPs consider the teclistamab + daratumumab regimen a triplet because of this, which may contribute to increased financial toxicity

What is IVIg use
