PURPOSE

Lorlatinib significantly improved progression-free survival (PFS) versus crizotinib and showed robust intracranial activity in patients with previously untreated advanced ALK-positive non–small-cell lung cancer (NSCLC) in the phase III CROWN trial. Here, we report post hoc efficacy outcomes in patients with and without brain metastases at baseline, and present data on the incidence and management of CNS adverse events (AEs) in CROWN.

METHODS

Eligible patients were randomly assigned 1:1 to first-line lorlatinib (100 mg once daily) or crizotinib (250 mg twice a day); no crossover between treatment arms was permitted. Tumor assessments, including CNS magnetic resonance imaging, were performed at screening and then at 8-week intervals. Regular assessments of patient-reported outcomes were conducted.

RESULTS

PFS by blinded independent central review was improved with lorlatinib versus crizotinib in patients with and without brain metastases at baseline (12-month PFS rates: 78% v 22% and 78% v 45%, respectively). Lorlatinib was associated with lower 12-month cumulative incidence of CNS progression versus crizotinib in patients with (7% v 72%) and without (1% v 18%) brain metastases at baseline. In total, 35% of patients had CNS AEs with lorlatinib, most of grade 1 severity. Occurrence of CNS AEs did not result in a clinically meaningful difference in patient-reported quality of life. At analysis, 56% of CNS AEs had resolved (33% without intervention; 17% with lorlatinib dose modification), and 38% were unresolved; most required no intervention. Lorlatinib dose modification did not notably influence PFS.

CONCLUSION

First-line lorlatinib improved PFS outcomes and reduced CNS progression versus crizotinib in patients with advanced ALK-positive non–small-cell lung cancer with or without brain metastases at baseline. Half of all CNS AEs resolved without intervention or with lorlatinib dose modification.

INTRODUCTION

Lorlatinib is a potent, third-generation inhibitor of anaplastic lymphoma kinase (ALK) indicated for the first-line treatment of adult patients with ALK-positive metastatic non–small-cell lung cancer (NSCLC).1,2 In the phase III CROWN study (ClinicalTrials.gov identifier: NCT03052608), independently assessed progression-free survival (PFS) was significantly improved with lorlatinib compared with crizotinib (hazard ratio [HR] for disease progression or death, 0.28; 95% CI, 0.19 to 0.41; P < .001) in this patient population.2

CONTEXT

  • Key Objective

  • Brain metastases develop in more than half of patients with ALK-positive non–small-cell lung cancer (NSCLC); these are associated with poor prognosis, high symptom burden, and decreased quality of life. We report a post hoc exploratory analysis of efficacy from the phase III CROWN study of lorlatinib versus crizotinib in patients with advanced treatment-naïve ALK-positive NSCLC by the presence/absence of brain metastases at baseline, and the safety/management of CNS-related adverse events.

  • Knowledge Generated

  • Lorlatinib improved progression-free survival and reduced CNS progression versus crizotinib regardless of the presence/absence of brain metastases at baseline. For many patients, CNS adverse events were managed either without any intervention or through dose modifications (with/without concomitant medication). Dose modifications had no detectable effect on lorlatinib efficacy on the basis of ad hoc progression-free survival analysis.

  • Relevance

  • Our data support lorlatinib as first-line treatment in patients with advanced ALK-positive NSCLC with/without brain metastases.

Approximately 29%-40% of patients with ALK-positive NSCLC have brain metastases at initial evaluation, and more than half will develop brain metastases.3-8 Development of brain metastases in patients with NSCLC is associated with significant morbidity, reduction in quality of life,9-11 and increased health care utilization with substantial financial burden because of increased inpatient, outpatient, and pharmacy costs.12,13 Although three ALK tyrosine kinase inhibitors (alectinib,14,15 brigatinib,16 and ensartinib8) have demonstrated superior efficacy to crizotinib in patients with brain metastases, prognosis among patients with NSCLC and brain metastases remains poor.9,17

Lorlatinib treatment in CROWN was associated with intracranial activity resulting in higher complete and partial intracranial response rates than with crizotinib in patients with brain metastases.2 Among the 78 patients with baseline measurable or nonmeasurable brain metastases, the intracranial objective response rate (ORR) as assessed by blinded independent central review (BICR) was 66% with lorlatinib and 20% with crizotinib.2 Complete intracranial responses were seen in 61% and 15% of patients, respectively.2 The safety profile of lorlatinib in CROWN2 was consistent with that described in the preceding phase I/II study (ClinicalTrials.gov identifier: NCT01970865).18,19 The potential clinical impact of CNS adverse events (AEs), such as cognitive and mood effects, following lorlatinib treatment has been debated.20,21 It has been reported that most AEs with lorlatinib can be effectively managed by dose modification and concomitant medication,2,18,19,22 with low rates of permanent treatment discontinuation.2,18,19

Here, we present post hoc exploratory efficacy and safety outcomes from the CROWN study, including subgroup analyses in patients with and without brain metastases at baseline, and data on the incidence and management of CNS-related AEs.

METHODS

Data Source and Patients

CROWN (ClinicalTrials.gov identifier: NCT03052608) is an ongoing randomized phase III trial of patients with locally advanced or metastatic ALK-positive (determined by Ventana ALK [D5F3] companion diagnostic immunohistochemical assay) NSCLC. Details of study design, inclusion and exclusion criteria, and primary data have been previously reported.2 In brief, patients were randomly assigned 1:1 to either oral lorlatinib 100 mg once daily or oral crizotinib 250 mg twice a day, and stratified by the presence of brain metastases (yes/no) and ethnicity (Asian/non-Asian). Patients with asymptomatic treated or untreated brain metastases were eligible. Dose levels for lorlatinib could be reduced to either 75 mg once daily or 50 mg once daily, depending on AE type and severity.

The Protocol (online only) was approved by the institutional review board or independent ethics committee; all patients provided written informed consent before participating.

Procedures

Tumor assessments (including magnetic resonance imaging) were performed at screening, and then every 8 weeks (±1 week) starting from random assignment until disease progression (on the basis of BICR). Intracranial disease response was assessed by a modified version of Response Evaluation Criteria in Solid Tumors v1.1, which included up to five intracranial target lesions ≥ 5 mm in diameter assessed by gadolinium-enhanced magnetic resonance imaging with slices of 1 mm for lesions of 5 mm to < 10 mm.23 Patient-reported outcomes (PROs) were assessed on day 1 of each cycle using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30).

End Points

PFS by BICR, cumulative incidence of CNS progression and non-CNS progression as first progression event, intracranial complete response rate, duration of response (DOR), and safety were assessed by patient subgroup (with or without brain metastases at baseline). PFS by BICR was also assessed in subgroups of patients with brain metastases with or without prior brain radiotherapy. PROs were assessed in patients with and without CNS AEs.

Statistical Analyses

The statistical methodology has been previously described.2 To assess the impact of brain metastases and prior brain radiotherapy on efficacy, post hoc exploratory PFS analyses were conducted. The probability of the first event being CNS progression, non-CNS progression, or death was evaluated with a competing risk approach by estimating cumulative incidence functions. To assess the effect of lorlatinib dose modifications on efficacy, measured as relative dose intensity (RDI) or dose reduction, a post hoc PFS landmark analysis was performed. The landmark point of 16 weeks was chosen to allow for early assessment while providing sufficient time for potential dose modifications. P values were one-sided without adjustment for multiple comparisons.

A longitudinal random-intercept, random-slope, mixed-effect model was used to assess EORTC QLQ-C30 score change from baseline up to, but not including, end of treatment. The model had an intercept term, treatment, time (continuous variable), treatment by time, baseline, and randomization stratification factors as covariates. A ≥ 10-point minimally important difference from baseline in EORTC QLQ-C30 has been established as correlative with clinically meaningful change in disease symptoms and functioning.24 P values were two-sided without adjustment for multiple comparisons. PRO changes from baseline included all postbaseline assessments; the results were presented up to cycle 18 to ensure a meaningful sample size.

AEs were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events v4.03, and the grading of CNS AEs is provided in the Data Supplement (online only). CNS AEs were grouped according to Medical Dictionary for Regulatory Activities (MedDRA) v23.0 group terms into four categories: COGNITIVE EFFECTS (any event from high-level group terms [HLGT]: Cognitive and attention disorders and disturbances, Deliria [including confusion], or Mental impairment disorders); MOOD EFFECTS (any event from HLGT Anxiety disorders and symptoms, Depressed mood disorders and disturbances, Manic and bipolar mood disorders and disturbances, Mood disorders and disturbances not elsewhere classified, or Personality disorders and disturbances in behavior); SPEECH EFFECTS (any event from high-level term Speech and language abnormalities); and PSYCHOTIC EFFECTS (any event from Standardised MedDRA Queries narrow Psychosis and psychotic disorders or preferred term of Psychotic symptom).

RESULTS

Analyses are based on a data cutoff for the primary analysis of March 20, 2020. A CONSORT diagram of study flow and patient baseline characteristics have been previously published.2 Among the 149 patients in the lorlatinib arm, 38 (26%) had baseline brain metastases according to BICR assessment and of these, eight (21%) had received prior brain radiotherapy. Among the 147 patients in the crizotinib treatment arm, 40 (27%) had baseline brain metastases according to BICR assessment, of whom 10 (25%) had received prior brain radiotherapy.

PFS

In patients with brain metastases at baseline (n = 78), PFS by BICR was improved with lorlatinib (n = 38) compared with crizotinib (n = 40; median PFS not reached [NR] v 7.2 months; 12-month PFS rate 78% [95% CI, 60 to 88] v 22% [95% CI, 9 to 39]; HR, 0.20; 95% CI, 0.10 to 0.43; P < .0001; Fig 1A). Similarly, patients without brain metastases at baseline (n = 218) showed a significant improvement in PFS with lorlatinib (n = 111) versus crizotinib (n = 107; median PFS NR v 11.0 months; 12-month PFS rate 78% [95% CI, 69 to 85] v 45% [95% CI, 34 to 55]; HR, 0.32; 95% CI, 0.20 to 0.49; P < .0001; Fig 1B). In patients with brain metastases at baseline who received lorlatinib and had prior brain radiotherapy (n = 8), the 12-month PFS rate was 88% (95% CI, 39 to 98). In patients with baseline brain metastases who received lorlatinib without prior brain radiotherapy (n = 30), the 12-month PFS rate was 75% (95% CI, 55 to 87; Appendix Fig A1, online only). Median PFS was NR in either prior brain radiotherapy subgroup.

Cumulative Incidence of CNS and Non-CNS Progression

The cumulative incidence of CNS progression without prior non-CNS progression or death was lower with lorlatinib than with crizotinib in patients with and without brain metastases at baseline (Figs 2A and 2B). Twelve-month cumulative incidence rates of CNS progression were 7% with lorlatinib and 72% with crizotinib in patients with baseline brain metastases (HR, 0.07; 95% CI, 0.02 to 0.24) and 1% with lorlatinib and 18% with crizotinib in patients without baseline brain metastases (HR, 0.05; 95% CI, 0.01 to 0.42). Cumulative incidence of non-CNS progression was lower with lorlatinib than with crizotinib in patients with and without baseline brain metastases (Appendix Fig A2, online only).

Intracranial Complete Responses

Complete CNS responses with lorlatinib were seen in 23/38 (61%) patients with any brain metastases at baseline compared with 6/40 (15%) with crizotinib. In patients with at least one measurable brain metastasis at baseline, 12/17 (71%) had complete responses with lorlatinib compared with 1/13 (8%) with crizotinib (Fig 3).2 Median DOR with lorlatinib in patients with complete responses and measurable brain lesions at baseline was NR (range, 7.4-31.4 months); 10/12 patients (83%) had a DOR ≥ 12 months and 5/12 patients (42%) had a DOR ≥ 18 months. Most patients with intracranial complete responses were still receiving lorlatinib treatment at data cutoff (Appendix Fig A3, online only).

Two patients from the crizotinib arm were excluded from the plot as they did not have any postbaseline tumor assessment.

Incidence of CNS AEs Following Treatment

CNS AEs (independent of causality) were reported for 52/149 (35%) patients who received lorlatinib and 15/142 (11%) patients who received crizotinib. The incidence and severity of CNS AEs by cluster term in the lorlatinib arm are summarized in Table 1. Most patients with CNS AEs (32/52 [62%] in the lorlatinib arm and 11/15 [73%] in the crizotinib arm) had a maximum CNS AE severity of grade 1; 15 patients (29%) in the lorlatinib arm and four patients (27%) in the crizotinib arm had maximum severity of grade 2, and five (10%) in the lorlatinib arm had maximum severity of grade 3. There were no grade 4 or 5 CNS AEs. More than one CNS AE was reported in 19/149 (13%) patients in the lorlatinib arm. Further details on managing patients with psychotic effects are presented in the Data Supplement.

Time to first onset and duration of any CNS AEs and by cluster term with lorlatinib are detailed in Table 2. Of the 38 patients with brain metastases at baseline, 16 (42%) reported CNS AEs versus 36/111 patients (32%) without brain metastases at baseline (Data Supplement). There was no clear association between the location of brain metastases at baseline and type of CNS AE experienced (Data Supplement). The frequency of CNS AEs seemed higher among patients who had prior brain radiotherapy (5/9; 56%) than patients without prior brain radiotherapy (47/140; 34%; Data Supplement); it should be noted, however, that patient numbers were low in the prior brain radiotherapy subgroup.

Impact of CNS AEs With Lorlatinib on PROs

The impact of CNS AEs with lorlatinib on PROs over time, as evaluated by the EORTC QLQ-C30 Cognitive and Emotional Functioning domains, is shown in Appendix Fig A4 (online only). Emotional Functioning scores improved over time regardless of the occurrence of CNS AEs, and by cycle 18, clinically meaningful improvements were observed in patients with and without any CNS AEs or mood effects, but not in patients with cognitive effects (Appendix Figs A4B, A4D, and A4F). Although Cognitive Functioning scores generally declined over time (Appendix Figs A4A, A4C, and A4E), there was no clinically meaningful decline at any time point, with the one exception of cycle 3 in patients with mood effects. The estimated mean difference in change from baseline in Cognitive Functioning scores through cycle 38 between patients who experienced CNS AEs compared with those who did not was –4.85 (95% CI, –9.81 to 0.11; P = .06). Those patients who experienced cognitive AEs had a significantly greater decline in Cognitive Functioning scores through cycle 38 compared with patients who did not experience cognitive AEs (estimated mean difference, –6.34; 95% CI, –12.08 to –0.60; P = .03).

Management of CNS AEs

In total, 86 CNS AEs were reported in 52 patients who received lorlatinib. Of those, 53 (62%) were managed without intervention, and 20 (23%) were managed with lorlatinib dose modification (reduction and/or interruption, with or without concomitant medication; Table 3). In two cases (2%), CNS AEs led to permanent treatment discontinuation (grade 2 confusion, one patient; grade 3 confusion, one patient). Of the 53 CNS AEs managed without intervention, 28 (53%) resolved, 1/53 (2%) improved, and 24/53 (45%) did not resolve. The majority (23/24) of the unresolved AEs were grade 1 in severity. Of the 20 CNS AEs managed with lorlatinib dose modifications, with or without concomitant medication, 15 (75%) resolved; 2/20 (10%) improved, and 3/20 (15%) did not resolve (two of grade 1 severity, and one of grade 2 severity). Lorlatinib dose modification alone was used for the management of 15 CNS AEs, of which 13 (87%) resolved, 1/15 (7%) improved, and 1/15 (7%) did not resolve (Table 3). Concomitant medication used for the management of CNS AEs and the duration of treatment are shown in the Data Supplement.

Impact of Lorlatinib Dose Modification on PFS

In total, 41/149 (28%) patients in CROWN had at least one lorlatinib dose reduction because of AEs. Landmark analysis of PFS showed comparable efficacy in patients with or without lorlatinib dose reduction within 16 weeks (12-month PFS rate 84% [95% CI, 49 to 96] with dose reduction [n = 17] v 84% [95% CI, 75 to 90] without dose reduction [n = 105]) and in patients categorized by the mean RDI of 98.6% by week 16 (Appendix Fig A5, online only). The 12-month PFS rate was 84% (95% CI, 75 to 90) in the subgroup whose RDI within 16 weeks was at or above the mean (n = 106), and 83% (95% CI, 45 to 96) in those whose RDI was below the mean (n = 16).

DISCUSSION

These additional post hoc analyses of data from the phase III CROWN study show that lorlatinib has potent and durable efficacy in patients with and without brain metastases at baseline, regardless of prior brain radiotherapy use. Furthermore, we demonstrate that, for some patients, CNS AEs can be managed either without any intervention or through appropriate dose modification.

About one quarter of the patients in CROWN had brain metastases, and lorlatinib prolonged PFS in this population compared with crizotinib (HR, 0.20; 95% CI, 0.10 to 0.43). The PFS benefit with lorlatinib was comparable with that seen with other ALK tyrosine kinase inhibitors in NSCLC in patients with baseline brain metastases (HR, 0.37; 95% CI, 0.23 to 0.58 in ALEX for first-line alectinib v crizotinib14; HR, 0.25; 95% CI, 0.14 to 0.46 in ALTA-1L for brigatinib v crizotinib in ALK inhibitor–naïve patients16). In patients without brain metastases at baseline, improvements in PFS seen with lorlatinib versus crizotinib (HR, 0.32; 95% CI, 0.20 to 0.49) appear to be greater than those seen with alectinib versus crizotinib (HR, 0.46; 95% CI, 0.31 to 0.68), or with brigatinib versus crizotinib (HR, 0.65; 95% CI, 0.44 to 0.97).14,16 One factor likely to contribute to the improved PFS with lorlatinib over crizotinib is the high intracranial complete response rate in patients treated with lorlatinib (71% in patients with measurable brain lesions at baseline), which is numerically higher than that observed in the ALEX (38%) and ALTA-1L (28%) trials.4,16

Patients with ALK-positive NSCLC are more likely to develop brain metastases than patients with RET- or ROS1-rearranged NSCLC, with a cumulative incidence of > 60% at 6 years.7 Lorlatinib was highly effective at preventing CNS progression in the majority of patients. In CROWN, the 12-month cumulative incidence rate of CNS progression in patients treated with lorlatinib with or without brain metastases at baseline was 7% and 1%, respectively. Data from the ALEX trial showed 12-month cumulative incidence rates of CNS progression following alectinib treatment of 16% in patients with baseline brain metastases and 5% in patients without.25

No clinically meaningful differences were previously identified between treatment arms in any EORTC QLQ-C30 functioning domain, although improvements favoring crizotinib were observed in the Cognitive Functioning scale.26 The findings reported here show that overall CNS AEs in the lorlatinib arm did not negatively affect EORTC QLQ-C30 Cognitive or Emotional Functioning domain scores over time but did have a negative impact on Cognitive Functioning and Emotional Functioning scores.

CNS AEs occurred in 35% of patients treated with lorlatinib compared with 11% of patients treated with crizotinib. More than half (62%) of the CNS AEs with lorlatinib were managed without intervention; of these, 53% resolved spontaneously. Only 2% led to permanent treatment discontinuation. Dose modification was used to manage 23% of CNS AEs and did not appear to negatively affect lorlatinib efficacy as indicated by a 12-month landmark PFS analysis, although patient numbers were small and the majority of dose-reduced patients were not included in this analysis. This is consistent with the results from a phase I/II trial that found no significant association between lorlatinib plasma exposure and ORR or intracranial ORR.27 In cases where there was no intervention, 45% of CNS AEs did not resolve, indicating these events may have required further management other than use of concomitant medications or were considered mild enough to be manageable without intervention.

We note several limitations to this analysis. CNS AEs can be difficult to assess, therefore some events may be under-reported. Consistent with this, patients with and without reported CNS AEs experienced some decline in Cognitive Functioning scores over time. Moreover, it is not possible to assess the full duration of all CNS AEs, since 38% of events were not resolved during the follow-up period. We also note that more specific neurologic scales may better assess the impact of specific CNS AEs on patient quality of life than the EORTC QLQ-C30. Data regarding the specific type of prior radiotherapy were not collected.

In conclusion, lorlatinib improved PFS outcomes and reduced CNS progression in patients with previously untreated advanced ALK-positive NSCLC with or without brain metastases at baseline. Intracranial responses were durable, and many CNS AEs resolved without intervention, or with lorlatinib dose modification and/or concomitant medication. These data support the use of lorlatinib as first-line treatment in patients with advanced ALK-positive NSCLC.
