RESUMO

BACKGROUND: Brigatinib, a next-generation anaplastic lymphoma kinase (ALK) inhibitor, has robust efficacy in patients with ALK-positive non-small-cell lung cancer (NSCLC) that is refractory to crizotinib. The efficacy of brigatinib, as compared with crizotinib, in patients with advanced ALK-positive NSCLC who have not previously received an ALK inhibitor is unclear. METHODS: In an open-label, phase 3 trial, we randomly assigned, in a 1:1 ratio, patients with advanced ALK-positive NSCLC who had not previously received ALK inhibitors to receive brigatinib at a dose of 180 mg once daily (with a 7-day lead-in period at 90 mg) or crizotinib at a dose of 250 mg twice daily. The primary end point was progression-free survival as assessed by blinded independent central review. Secondary end points included the objective response rate and intracranial response. The first interim analysis was planned when approximately 50% of 198 expected events of disease progression or death had occurred. RESULTS: A total of 275 patients underwent randomization; 137 were assigned to brigatinib and 138 to crizotinib. At the first interim analysis (99 events), the median follow-up was 11.0 months in the brigatinib group and 9.3 months in the crizotinib group. The rate of progression-free survival was higher with brigatinib than with crizotinib (estimated 12-month progression-free survival, 67% [95% confidence interval {CI}, 56 to 75] vs. 43% [95% CI, 32 to 53]; hazard ratio for disease progression or death, 0.49 [95% CI, 0.33 to 0.74]; P<0.001 by the log-rank test). The confirmed objective response rate was 71% (95% CI, 62 to 78) with brigatinib and 60% (95% CI, 51 to 68) with crizotinib; the confirmed rate of intracranial response among patients with measurable lesions was 78% (95% CI, 52 to 94) and 29% (95% CI, 11 to 52), respectively. No new safety concerns were noted. CONCLUSIONS: Among patients with ALK-positive NSCLC who had not previously received an ALK inhibitor, progression-free survival was significantly longer among patients who received brigatinib than among those who received crizotinib.

RESUMO

Purpose In patients with crizotinib-treated, anaplastic lymphoma kinase gene ( ALK)-rearranged non-small-cell lung cancer (ALK-positive NSCLC), initial disease progression often occurs in the CNS. We evaluated brigatinib, a next-generation ALK inhibitor, in patients with ALK-positive NSCLC with brain metastases. Patients and Methods Patients with ALK-positive NSCLC received brigatinib (90 to 240 mg total daily) in a phase I/II trial (phI/II; ClinicalTrials.gov identifier: NCT01449461) and in the subsequent randomized phase II trial ALTA (ALK in Lung Cancer Trial of AP26113; ClinicalTrials.gov identifier: NCT02094573; patients in arm A received 90 mg once daily; patients in arm B received 180 mg once daily with 7-day lead-in at 90 mg). Primary end points (systemic objective response rates [ORRs]) were previously reported. Independent review committees assessed intracranial efficacy in patients with baseline brain metastases. Results Most patients with ALK-positive NSCLC had baseline brain metastases (50 of 79 [63%], phI/II; 80 of 112 [71%] and 73 of 110 [66%] in ALTA arms A and B, respectively), many of whom had no prior brain radiotherapy (23 of 50 [46%], phI/II; 32 of 80 [40%], ALTA arm A; 30 of 73 [41%], arm B). All patients, except four in phI/II, had received crizotinib. Among patients with measurable (≥ 10 mm) brain metastases, confirmed intracranial ORR was 53% (eight of 15; 95% CI, 27% to 79%) in phI/II, 46% (12 of 26; 95% CI, 27% to 67%) in ALTA arm A, and 67% (12 of 18; 95% CI, 41% to 87%) in arm B. Intracranial ORRs were similar in subsets without prior radiation or progression postradiation. Among patients with any baseline brain metastases, median intracranial progression-free survival (iPFS) was 14.6 months (95% CI, 12.7 to 36.8 months), phI/II; 15.6 months (95% CI, 9.0 to 18.3 months), ALTA arm A; 18.4 months (95% CI, 12.8 months to not reached), ALTA arm B. Conclusion Brigatinib yielded substantial intracranial responses and durable iPFS in ALK-positive, crizotinib-treated NSCLC, with highest iPFS in patients receiving 180 mg once daily (with lead-in).

RESUMO

OBJECTIVE: To examine the relationship between the pharmacodynamic and antipsoriatic effects of alefacept, a biologic agent that targets CD4+ and CD8+ memory T cells. DESIGN: Randomized, double-blind, placebo-controlled study of 3 parallel groups. SETTING: Fifty-one study centers. PATIENTS: Five hundred fifty-three patients with chronic plaque psoriasis. INTERVENTIONS: Patients were randomized (1:1:1) to 1 of the following 3 cohorts: alefacept, 7.5 mg, in both courses (cohort 1); alefacept, 7.5 mg, in the first course and placebo in the second course (cohort 2); or placebo in the first course and alefacept, 7.5 mg, in the second course (cohort 3). In each course, alefacept or placebo was administered by intravenous bolus once weekly for 12 weeks, followed by 12 weeks of observation. MAIN OUTCOME MEASURES: Circulating lymphocyte levels and the Psoriasis Area Severity Index. RESULTS: One or 2 courses of alefacept reduced CD4+ and CD8+ memory T-cell counts, while sparing the naive population. At 12 weeks after the last dose of alefacept in courses 1 and 2, 88% and 83% of patients, respectively, had CD4+ cell counts greater than the lower limit of normal. In course 1, alefacept-treated patients with the largest decreases in memory T-cell counts experienced the greatest reductions in disease activity (P<.001). The duration of clinical benefit seemed to be longer among patients who had the greatest reduction in CD4+ and CD8+ memory T-cell counts. CONCLUSIONS: One or 2 courses of intravenous alefacept reduced circulating memory T-cell counts while sparing the naïve T-cell population. The reductions in memory T-cell counts were related to all measures of disease activity evaluated and the duration of response to therapy, suggesting that prolonged remissions of psoriasis can be attained with reduction of the pathogenic T-cell count.

RESUMO

OBJECTIVE: Although spirituality is viewed as a vital aspect of the illness experience by most Americans, little is known about this domain of pediatric health care. The objective of this study was to profile pastoral care providers' perceptions of the spiritual care needs of hospitalized children and their parents, barriers to better pastoral care, and quality of spiritual care in children's hospitals. METHODS: A cross-sectional mail survey was conducted of pastoral care providers at children's hospitals throughout the United States, with a 67% response rate from 115 institutions. RESULTS: Respondents estimated that, among patients they visited, 34% were chronically ill and 21% were clearly dying. Half or more of patients were thought to have spiritual care needs regarding feeling fearful or anxious, coping with pain or other physical symptoms, and regarding their relationship to their parents or the relationship between their parents. Among patients' parents, 60% to 80% were estimated to have felt fearful or anxious, had difficulty coping with their child's pain or other symptoms, sought more medical information about their child's illness, questioned why they and their child were going through this experience, asked about the meaning or purpose of suffering, and felt guilty. Respondents agreed on 3 barriers to providing spiritual care: inadequate staffing of the pastoral care office, inadequate training of health care providers to detect patients' spiritual needs, and being called to visit with patients and families too late to provide all the care that could have been provided. Overall, respondents judged that their hospitals were providing 60% of what they deemed as ideal spiritual care. CONCLUSIONS: Pastoral care providers believe that the spiritual care needs of hospitalized children and their parents are diverse and extensive. With system-level barriers cited as limiting the quality of spiritual care, considerable improvement may be possible.
