• Patients had a 55% likelihood of remaining alive without disease progression at seven years, and median progression-free survival was not reached with LORBRENA
  • Updated follow-up analysis solidifies LORBRENA as a preferred standard of care, building upon five-year results

Pfizer Inc. (NYSE:PFE) today announced unprecedented seven-year follow-up results from the Phase 3 CROWN trial evaluating LORBRENA® (lorlatinib, a third-generation ALK inhibitor, available in Europe under the brand name LORVIQUA®) versus XALKORI® (crizotinib) in people with previously untreated, anaplastic lymphoma kinase (ALK)-positive advanced or metastatic non-small cell lung cancer (NSCLC).

At seven years, patients treated with LORBRENA had a 55% likelihood of remaining alive without disease progression (95% Confidence Interval [CI], 46-63) compared to 3% (95% CI, 1-8) in the XALKORI treatment arm. Further, an updated analysis at seven years of median follow-up showed that investigator-assessed median progression-free survival (PFS) had not been reached with LORBRENA, with an estimated Hazard Ratio (HR) of 0.19 (95% CI, 0.13-0.26), representing an 81% reduction in the risk of disease progression or death compared to XALKORI. Full results from the analysis will be presented today in an oral presentation at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract #8502) and simultaneously published in Annals of Oncology.

The safety profiles of LORBRENA and XALKORI were consistent with previous findings, with no new safety signals observed. In this analysis, the most frequent (≥20%) adverse events (AEs) of interest reported in patients treated with LORBRENA included edema, weight gain, peripheral neuropathy, cognitive effects, mood effects, diarrhea, dyspnea, arthralgia, hypertension, headache, cough, pyrexia, hypercholesterolemia, and hypertriglyceridemia. All-cause grade 3/4 AEs occurred in 77% of patients with LORBRENA and in 57% of patients with XALKORI. Treatment-related AEs led to permanent treatment discontinuation in 5% and 6% of patients in the LORBRENA and XALKORI arms, respectively. No new permanent discontinuations due to treatment-related AEs occurred after the first 26 months with LORBRENA.
