From AbbVie and Lida Pacaud Advance Trispecific T-cell Engager for Multiple Myeloma

How could AbbVie's new oncology drug development affect Pfizer?

Possible What happens if… A possibility worth considering, not a forecast.

AbbVie's novel multiple myeloma drug could increase competition for Pfizer. AbbVie has partnered with IGI to advance ISB 2001, a first- and only-in-class CD38 x BCMA x CD3 trispecific T-cell engager for relapsed/refractory multiple myeloma (RRMM). Initial Phase 1 data from the TRIgnite-1 study showed the drug demonstrated robust efficacy and tolerability. As a direct competitor to Pfizer in the pharmaceutical market, the successful development and potential market entry of this novel treatment option strengthens AbbVie's standing in the oncology sector, increasing competitive pressure on Pfizer.

The facts so far

As reported. Each one links to where it comes from.

  • ISB 2001 (ABBV-2001) is an investigational first- and only-in-class CD38 x BCMA x CD3 trispecific T-cell engager.manilatimes.net
  • The drug targets patients with relapsed/refractory multiple myeloma (RRMM).manilatimes.net
  • The partnership between IGI and AbbVie was formed via an exclusive global licensing agreement in July 2025.manilatimes.net
  • Updated Phase 1 data from the TRIgnite-1 study demonstrated robust efficacy and tolerability.manilatimes.net

Why it matters

The development of new, highly targeted therapies for relapsed/refractory multiple myeloma is critical, as this condition often requires aggressive and specialized treatment options. A first-in-class drug like ISB 2001 represents a significant potential advancement in patient care and could capture substantial market share in the oncology sector.

Pfizer and AbbVie are major players in the pharmaceutical market, and their competition is fierce, particularly in high-value therapeutic areas like oncology. AbbVie's ability to successfully advance a novel, promising drug through a partnership increases its competitive leverage against its peers, including Pfizer.

What we don't know yet

  • What are the results of the Phase 1/2 combination study for ISB 2001?
  • What is the timeline for regulatory review and potential market approval for ISB 2001?

What would change this answer

The Phase 1/2 combination study shows even stronger efficacy and tolerability data.The competitive pressure on Pfizer would increase, potentially leading to a stronger market impact for AbbVie.
The drug fails to meet efficacy benchmarks in later-stage trials.The competitive advantage gained by AbbVie would diminish, reducing the impact on Pfizer.
