For patients with an anaplastic lymphoma kinase rearrangement, a performance status (PS) of 0-2, and previously untreated NSCLC, clinicians should offer…lorlatinib.

Non-Small Cell Lung Cancer: ALK Rearrangement Positive…First-line therapy…Lorlatinib… ALK REARRANGEMENT POSITIVE….SUBSEQUENT THERAPY...Alectinib or brigatinib or ceritinib or lorlatinib

In ALK-rearranged patients progressing on crizotinib, treatment with next-generation ALK TKIs, such as alectinib [I, A], ceritinib [I, A] brigatinib [III, A] or lorlatinib [III, A], is recommended.

We reviewed the course of 144 patients with advanced ALK- or ROS1-rearranged NSCLC treated with lorlatinib in the second-line or later setting to assess the frequency of dose reductions resulting from treatment-related AEs (TRAEs) and the association between dose reductions and progression-free survival (PFS) and overall survival (OS)....Among all patients, the median PFS was 8.1 months (95% confidence interval [CI]: 6.4-11.8); the median OS was 20.7 months (95% CI: 16.3-30.5).

We aimed to report result of lorlatinib in real-world practice....A total 52 ALK -positive patients were enrolled....The objective response rate was 22% and disease control rate was 88%....This real-world efficacy and adverse event on lorlatinib for Taiwanese ALK-rearranged NSCLC are compatible to those reported in global clinical trial.

We included RCTs comparing ALK inhibitors with cytotoxic chemotherapy or another ALK inhibitor in individuals with incurable locally advanced or metastatic pathologically confirmed ALK‐rearranged NSCLC...five studies compared a next‐generation ALK inhibitor (alectinib, brigatinib, and lorlatinib) to crizotinib....Next‐generation ALK inhibitors resulted in a large increase in PFS (HR 0.39, 95% CI 0.33 to 0.46, 5 RCTs, 1263 participants, high‐certainty evidence), particularly in participants with baseline brain metastases….Next‐generation ALK inhibitors likely increase OS (HR 0.71, 95% CI 0.56 to 0.90, 5 RCTs, 1263 participants, moderate‐certainty evidence) and slightly increase ORR (RR 1.18, 95% CI 1.10 to 1.25, 5 RCTs, 1229 participants, moderate‐certainty evidence) including a response in measurable brain metastases (RR 2.45, 95% CI 1.7 to 3.54, 4 RCTs, 138 participants) when compared to crizotinib.

Here, we indirectly compared the efficacy and safety of first-line systemic therapeutic options used for the treatment of ALK-rearranged NSCLC….Our analysis showed that alectinib (300 mg and 600 mg), brigatinib, lorlatinib and ensartinib yielded the most favorable PFS....According to Bayesian ranking profiles, lorlatinib, alectinib 600 mg and alectinib 300 mg had the best PFS (63.7%), OS (35.9%) and ORR (37%), respectively.

This study describes the outcomes of lorlatinib treatment for 35 non-small cell lung cancer patients with ALK rearrangements...Objective tumor response (OR) and disease control (DC) were registered in 15/35 (43%) and 33/35 (94%) patients, respectively...

NSCLCBM patients between 2010 and 2019 were evaluated....16 ALK positive patients received first-generation ALK inhibitor (crizotinib)...17 patients received second-generation (alectinib, ceritinib, brigatinib) and third-generation ALK inhibitors (lorlatinib)...The 5-year OS rate was 49% (95% confidence interval (CI) = 24%, 71%) for first-generation ALK inhibitors and 76% (95% CI = 40%, 92%) for second and third-generation ALK inhibitors (p-value (p) = 0.019).

Lorlatinib showed clinically meaningful responses and IC-responses among ALK-rearranged Japanese patients with NSCLC who received ≥1 prior ALK TKI, including meaningful responses among those receiving prior alectinib only. Lorlatinib was generally well tolerated.

Lorlatinib is a potent ALK and ROS-1 inhibitor that also has activity against many acquired ALK resistance mutations. Clinical trials show the robust systemic and intracranial anti-tumor activity of lorlatinib in ALK rearranged advanced NSCLC.

In this phase 1, dose-escalation study, lorlatinib showed both systemic and intracranial activity in patients with advanced ALK-positive or ROS1-positive NSCLC, most of whom had CNS metastases and had previously had two or more TKI treatments fail.
