> Investigator-assessed longer follow-up of the ALEX study demonstrated sustained benefit in the reduction of the risk of disease progression or death (57%) for people treated with Alecensa

> Alecensa more than tripled median progression-free survival (PFS) (34.8 months compared to 10.9 months for crizotinib)

> Investigator-assessed median PFS for people without CNS metastases at baseline was 34.8 months with Alecensa versus 14.7 months with crizotinib, while the median PFS for people with CNS metastases at baseline was 27.7 months with Alecensa versus 7.4 months with crizotinib


Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced follow-up data from the phase III ALEX study, showing that, as an initial treatment, Alecensa® (alectinib) significantly reduced the risk of disease progression or death (progression-free survival; PFS) by 57% (hazard ratio [HR]= 0.43, 95% CI: 0.32-0.58) compared to crizotinib after two years of follow-up in people with anaplastic lymphoma kinase (ALK)-positive metastatic (advanced) non-small cell lung cancer (NSCLC), as assessed by the investigator.1 The median PFS for people who received Alecensa was more than tripled compared to those who received crizotinib (34.8 months [95% CI: 17.7 months-NE) versus 10.9 months [95% CI: 9.1-12.9 months)], respectively, as assessed by the investigator. The safety profile for Alecensa was consistent with that observed in previous studies.

“Follow-up results from the ALEX study demonstrate the significant sustained benefit of Alecensa, showing that people with metastatic ALK-positive non-small cell lung cancer lived for almost three years without their disease progressing,” said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. “These results further support the use of Alecensa as a standard of care for people who are newly diagnosed with this form of lung cancer.”

The longer-term analysis also included follow-up data for secondary endpoints of the ALEX study. Alecensa demonstrated superior efficacy compared to crizotinib regardless of the presence of central nervous system (CNS) metastases at baseline. Investigator-assessed median PFS for people without CNS metastases at baseline was 34.8 months with Alecensa (95% CI: 22.4-NE) versus 14.7 months (95% CI: 10.8-20.3) with crizotinib (HR=0.47, 95% CI: 0.32-0.71). Investigator-assessed median PFS for people with CNS metastases at baseline was 27.7 months in the Alecensa arm (95% CI: 9.2-NE) versus 7.4 months (95% CI: 6.6-9.6) in the crizotinib arm (HR=0.35, 95% CI: 0.22-0.56). 1 The duration of response (DOR) for people who received Alecensa was 33.3 months (95% CI: 31.3-NE) compared to 11.1 months (95% CI: 7.5-13.0 months) for people who received crizotinib.1

The data will be presented at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting on Sunday, 3 June, 2018 at 08:00 – 11:30 am CDT (Abstract #9043).

Alecensa is now approved in more than 45 countries as an initial (first-line) treatment for ALK-positive, advanced NSCLC, including in the United States, Europe and Japan.


About the ALEX study2

ALEX (NCT02075840/B028984) is a randomised, multicentre, open-label, phase III study evaluating the efficacy and safety of Alecensa versus crizotinib in treatment-naïve people with ALK-positive NSCLC whose tumours were characterised as ALK-positive by the VENTANA ALK (D5F3) CDx Assay, a companion immunohistochemistry (IHC) test developed by Roche Tissue Diagnostics. People were randomised (1:1) to receive either Alecensa or crizotinib. The primary endpoint of the ALEX study was PFS as assessed by the investigator, and secondary endpoints include: Independent Review Committee (IRC)-assessed PFS, time to CNS progression, objective response rate (ORR), DOR and overall survival (OS). The multicentre study was conducted in 303 people across 161 sites in 31 countries. OS data are currently considered immature with only about a third of events being reported.

Primary data from the ALEX study were previously presented at the 2017 ASCO Annual Meeting and published in the New England Journal of Medicine.3 Follow-up results from the ALEX study analysis to be presented at the 2018 ASCO Annual Meeting showed1:

> After a further 10 months of follow-up, Alecensa reduced the risk of disease worsening or death (PFS) by 57% compared to crizotinib (HR=0.43, 95% CI: 0.32-0.58). Median follow-up was 27.8 months versus 22.8 months for Alecensa-treated patients and crizotinib-treated patients, respectively.

> Investigator-reported median PFS (the primary endpoint) was 34.8 months in the Alecensa arm (95% CI: 17.7-NE) versus 10.9 months (95% CI: 9.1-12.9 months) in the crizotinib arm.

> ORR for people treated with Alecensa was 82.9% (95% CI: 75.95-88.51) compared to 75.5% (95% CI: 67.84-82.12) for people treated with crizotinib, as assessed by the investigator.

> Alecensa demonstrated superior efficacy compared to crizotinib regardless of the presence or absence of CNS metastases at baseline. Investigator-assessed median PFS for people without CNS metastases at baseline was 34.8 months with Alecensa (95% CI: 22.4-NE) versus 14.7 months (95% CI: 10.8-20.3) with crizotinib (HR=0.47, 95% CI: 0.32-0.71). Investigator-reported median PFS for people with CNS metastases at baseline was 27.7 months in the Alecensa arm (95% CI: 9.2-NE) versus 7.4 months (95% CI: 6.6-9.6) in the crizotinib arm (HR=0.35, 95% CI: 0.22-0.56).

> Improvements were observed in the time between first response to treatment and disease worsening (DOR): 33.3 months with Alecensa versus 11.1 months with crizotinib.

> Grade 3-5 adverse events (AEs) were less frequent in the Alecensa arm (44.7%) compared to the crizotinib arm (51.0%). The most common Grade 3-4 AEs were increased liver enzymes (aspartate transaminase; 5.5%, and alanine transaminase; 4.6%) and increased muscle enzymes (creatine phosphokinase; 3.3%). Serious adverse reactions reported in = 2% of people treated with Alecensa were acute kidney injury (2.6%) and decreased red blood cells (anaemia; 2.0%).

> AEs leading to dose reduction (16.4% versus 20.5%) and dose interruption (22.4% versus 25.2%) were lower in the Alecensa arm compared with the crizotinib arm. AEs leading to discontinuation were equal in both arms (13.2%).

The FDA approval of Alecensa for the treatment of people with ALK-positive metastatic NSCLC was based on results from the phase III ALEX study from the primary data cutoff in February 2017. Results showed that:

> Alecensa significantly reduced the risk of disease worsening or death (PFS) by 47% (HR=0.53, 95% CI: 0.38-0.73, p<0.001) compared to crizotinib as assessed by an IRC.

> The median PFS was 25.7 months (95% CI: 19.9-NE) for people who received Alecensa compared with 10.4 months (95% CI: 7.7-14.6) for people who received crizotinib as assessed by an IRC.

> Alecensa significantly reduced the risk of the cancer spreading to, or growing in, the brain or CNS compared to crizotinib by 84% (HR=0.16, 95% CI: 0.10-0.28, p<0.0001). This was based on a time to CNS progression analysis in which there was a lower risk of progression in the CNS as the first site of disease progression for people who received Alecensa (12%) compared to people who received crizotinib (45%).

> The safety profile of Alecensa was consistent with that observed in previous studies.

> Grade = 3 adverse reactions were reported for 41% of people treated with Alecensa. The most common Grade 3-4 adverse reactions (= 3%) were evidence of kidney dysfunction (increased creatinine; 4.1%), evidence of liver dysfunction (hyperbilirubinemia; 5%), low levels of sodium (hyponatremia; 6%), increased liver enzymes (aspartate transaminase; 6%, and alanine transaminase; 6%), and decreased red blood cells (anaemia; 7%). Serious adverse reactions reported in = 2% of people treated with Alecensa were pneumonia (4.6%) and renal impairment (3.9%).
