🔥 FOURLIGHT-1 demonstrates atirmociclib efficacy post-CDK4/6i
⚠️ Phase II trial: not practice-changing yet
👉 These results reinforce expectations that atirmociclib may outperform other CDK4/6i
➡️ FOURLIGHT-3 results eagerly awaited
Congrats to my friend @antgiorda

Efficacy and safety of atirmociclib (ATI) + fulvestrant (FUL) in patients (pts) with HR+/HER2– advanced/metastatic breast cancer (mBC) who progressed on prior CDK4/6 inhibitor (CDK4/6i) in a randomized phase 2 study (FOURLIGHT-1)

@BianchiniGP @antgiorda Kudos to the team. 9.4 vs 6.6 months median PFS post-CDK4/6i deserves attention, though investigator-assessed endpoints in a Phase II warrant caution. I would hold on implications until the Phase III. Look forward to FOURLIGHT-3. #ESMO26
