Eric Singhi: My thoughts on the COCOON trial from ELCC25

Eric Singhi, Assistant Professor in the Department of General Oncology at The University of Texas MD Anderson Cancer Center, shared a post on X:

“COCOON data at ELCC25 – can prophylactic enhanced dermatologic management prevent moderate to severe dermatological AEs with amivantamab + lazertinib?

Eric Singhi: My thoughts on the COCOON trial from ELCC25

COCOON reaches primary endpoint

Within first 12 weeks,

  • G2+ dermatologic AEs low from 76.5% to 38.6%
  • G3 dermatologic AEs low from 8.8% to 4.3%

Eric Singhi: My thoughts on the COCOON trial from ELCC25

Meaningful slide – scalp lesions remain one of the most challenging dermatologic AEs with this combination.

Encouraging to see about a 70% reduction in G2+ scalp dermatologic AEs (29% v 9%), though small numbers.

Encouraging to see that patients who received prophylactic enhanced dermatologic management had lower AE-related discontinuation rates (11% v 19%).

S/p COCOON and MARIPOSA OS data, my thoughts:

  • The hand that prescribes MARIPOSA must schedule a dermatology consult and the prophylactic COCOON regimen.
  • Supportive care can effectively keep patients on treatment and is essential to fully realize the benefit we aim for.”
