New First-Line Treatment for Metastatic Nonsquamous NSCLC
December 4, 2019—Indications for atezolizumab have been expanded to include its use in combination with chemotherapy for the first-line treatment of adults with EGFR/ALK wildtype metastatic nonsquamous NSCLC.
This approval was based on data from the phase III IMpower130 study in the intention-to-treat wild-type population, which demonstrated an improved median OS for atezolizumab plus chemotherapy vs chemotherapy alone (18.6 vs 13.9 months, respectively; HR = 0.80; 95% CI = 0.64–0.99; p = 0.04). Progression-free survival and risk of death were also improved (median PFS = 7.2 vs 6.5 months; HR = 0.75; 95% CI = 0.63–0.91; p = 0.002). No new safety signals for the agent were identified in the trial, with 73.2% of patients who received the agent experiencing grade 3/4 adverse events compared with 60.0% of patients who received chemotherapy alone.
Atezolizumab is already approved as first-line therapy for metastatic nonsquamous NSCLC in combination with bevacizumab, paclitaxel, and carboplatin. It is also approved as a first-line therapy for patients with extensive-stage SCLC when combined with chemotherapy.
Osimertinib Performs as Expected for Previously Untreated Patients with NSCLC
September 29, 2019—The final OS results from an analysis conducted from the phase III FLAURA trial demonstrated significantly improved OS for osimertinib compared with gefitinib or erlotinib for previously untreated patients with locally advanced or metastatic NSCLC and with EGFR exon 19 or L858R mutations. Median OS for osimertinib was 38.6 months vs 31.8 months for erlotinib or gefitinib (HR 0.799; 95.05% CI, 0.641-0.997; p = 0.0462), even with crossover allowed for first-generation– treated patients who developed the T790M resistance mutation. OS rates for osimertinib at 1, 2, and 3 years were 89%, 74%, and 54% vs 83%, 59%, and 44%, respectively. Overall, the median follow-up for patients who received osimertinib was 35.8 months vs 27.0 for the comparator, during which time 11 fewer deaths occurred in the osimertinib arm.
FLAURA discussant Pasi A. Jänne, MD, said in a press statement that the magnitude of benefit varied by subgroup, although outcomes were consistent across groups. “The study findings are practice changing; however, osimertinib is already approved for acquired resistance due to EGFR T790M in 87 countries worldwide and furthermore, it is approved for first-line treatment in 78 countries worldwide. But barriers to first-line use are cost and/or lack of reimbursement,” said Dr. Jänne.
CheckMate-227: Nivolumab/Ipilimumab Superior to Chemo in First-Line NSCLC with PD-L1 Expression > 1%
September 28, 2019—Part 1a of the phase III CheckMate-227 trial was successfully completed, with nivolumab plus low-dose ipilimumab yielding superior OS (median 17.1 months) compared to chemotherapy (14.9 months) for patients with NSCLC and PD-L1 expression of > 1% (HR 0.79; 97.72% CI: 0.65-0.96; p = 0.007). OS was also improved for patients with PD-L1 < 1% who received the combination therapy and in the study population overall. The safety profile for the combination was similar to previous findings published in The New England Journal of Medicine.1
A prior report of this study1 showed superior overall response and PFS for ipilimumab/nivolumab in patients with high TMB compared to standard platinum- based chemotherapy, independent of PD-L1 status, but high TMB did not translate into an OS benefit.

Atezolizumab Monotherapy Improves OS in Frontline NSCLC with High PD-L1
September 27, 2019—Atezolizumab monotherapy improved OS compared with platinum-based chemotherapy for previously untreated patients with advanced NSCLC and high PD-L1 expression (> 50% on tumor cells or > 10% on tumor-infiltrating immune cells), regardless of histology. The OS findings were confined to ALK/EGFR wild- type tumors. The phase III IMpower110 trial accrued 572 treatment-naive patients and reported on 555 wild type (ALK/ EGFR mutation negative) with previously untreated advanced nonsquamous or squamous NSCLC. Patients were randomly assigned to single-agent therapy with atezolizumab or to platinum-based chemotherapy. The primary endpoint was OS by PD-L1 subgroup; secondary endpoints included PFS, ORR, and duration of response. Median OS at 15.7 months follow-up (range 0-35) was 20.2 months for patients who received atezolizumab vs 13.1 months for those who received chemotherapy (HR = 0.59; 95% CI: 0.40-0.89; p = 0.0106). PFS was also improved with atezolizumab, with a median PFS of 8.1 months vs. 5.0 months (HR = 0.63; 95% CI: 0.45- 0.88; p = 0.007) in the same population. The ORR was 38.3% vs. 28.6%, respectively, and the median DOR was not reached for atezolizumab (vs 6.7 months for chemotherapy).
The Death of MERU
August 29, 2019—AbbVie closed the phase III placebo-controlled MERU trial evaluating rovalpituzumab-tesirine, an antibody–drug conjugate targeting the delta-like ligand 3 protein, as first-line maintenance therapy for extensive-stage SCLC in patients with stable disease or response to first-line etoposide and platinum. No survival benefit was seen versus placebo at a pre-planned interim analysis. The MERU data will be published in the future.
Entrectinib Wins Approval for ROS1-Positive NSCLC
August 15, 2019—The U.S. Food and Drug Administration (FDA) granted approval for entrectinib for the treatment of adults with ROS1-positive metastatic NSCLC and accelerated approval for treatment of both pediatric patients older than 12 and adults with solid tumors that harbor an NTRK fusion. The latter indication is tumor-agnostic, though it should be noted the NTRK fusions generally occur in fewer than 1% of patients with advanced NSCLC.
The approvals were based on data from the phase II STARTRK-2, phase I STARTRK-1, and the phase I ALKA-372-001 trials, which included 51 patients with ROS1-positive metastatic NSCLC. Various doses and schedules were examined in the three trials, but 90% of patients received 600 mg of oral entrectinib once daily, the recommended dose. Pooled data from these ongoing trials showed a 78% ORR (95% CI: 65, 89); 55% achieved responses for 12 months or more (median, 24.6 months; 1.8-36.8 months).
The most serious adverse reactions regardless of causality, included congestive heart failure, CNS effects, skeletal fractures, hepatotoxicity, hyperuricemia, QT interval prolongation, and vision disorders. The most common adverse reactions in at least 20% of patients included, but were not limited to, fatigue, constipation, dysgeusia, edema, dizziness, and diarrhea.
CASPIAN Trial to Report Improved OS for Durvalumab in SCLC
June 27, 2019—According to an interim analysis, the phase III CASPIAN trial (NCT03043872) of durvalumab plus etoposide and chemotherapy for previously untreated late-stage SCLC has met its primary endpoint of clinical and statistical OS improvement for durvalumab. Safety and tolerability was in line with known data for this drug.
This triple-arm, open-label, multicenter, global, randomized phase III trial was conducted in more than 200 centers in 22 countries. Eligible patients received standard etoposide/ platinum-based chemotherapy, either alone or in combination with durvalumab or durvalumab and tremelimumab.
Data will be presented at the 2019 IASLC World Conference on Lung Cancer.
Pembrolizumab Receives Third-Line Approval for Metastatic SCLC
June 17, 2019—Pembrolizumab received accelerated approval from the U.S. Food and Drug Administration for treatment of patients with metastatic SCLC with disease progression during or after platinum-based chemotherapy and at least one other line of therapy.
Approval was based on results from KEYNOTE-158 and KEYNOTE-028. A total of 83 patients received either 200 mg of IV pembrolizumab every 3 weeks (64 patients), which was found to be the recommended dosage, or 10 mg/kg IV every 2 weeks (19 patients). Treatment continued for a maximum of 24 months or until disease progression or unacceptable toxicity.
The ORR was 19% (95% CI: 11-29), and the CR rate was 2%. For the 16 patients who demonstrated a response, the percentage with durable responses at 6, 12 or more, and 18 or more months were 94%, 63%, and 56%, respectively. Study treatment was discontinued due to adverse events (AEs) in 9% of patients; 25% had at least one dose withheld due to an AE. Common AEs were fatigue, decreased appetite, cough, nausea, and constipation, each of which was in at least 20% of patients. Serious AEs occurred in 31% of patients, with pneumonia and pleural effusion being the most frequent (> 2%).
Pembrolizumab was granted orphan drug designation for SCLC in October 2017.
A Drug for an Undruggable Target
June 3, 2019—A novel small-molecule inhibitor targeting KRAS, known as AMG 510, demonstrated a 50% response rate in patients with NSCLC who had KRASG12C mutations, which are found in approximately 13% of lung adenocarcinomas and up to 3% of other solid tumors. Initial safety and response data from a first-in-human, open-label, phase I trial of this novel small-molecule KRAS inhibitor were presented at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting (NCT03600883) and found the agent to be well tolerated.
All patients in phase I had a KRASG12C mutation confirmed by DNA sequencing. Eligible patients had measurable or evaluable disease, an ECOG PS < 2, and a life expectancy of > 3 months. Patients with brain metastases and myocardial infarction within 6 months were excluded.
In the initial cohort of six patients with NSCLC, 15 with colorectal cancer, and one other, 10 discrete grade 1 or 2 treatment-related adverse events (TRAEs) were reported in five patients; there were no dose-limiting toxicities. In an update at ASCO, of 10 patients with advanced NSCLC and KRASG12C mutations, five registered a partial response. Twenty patients of the initial 22 are continuing treatment; maximum-tolerated dose has yet to be established.
Device Becomes Second Approved Therapy for Unresectable MPM
May 23, 2019—A new device was approved by the U.S. Food and Drug Administration (FDA) for use in the first-line setting for treatment of unresectable, locally advanced or metastatic malignant pleural mesothelioma (MPM). This is the first therapeutic approval in 15 years for MPM.
NovoTTF-100L is a tumor-treating fields (TTF) device, which uses electric fields to disrupt solid tumor cancer cell division. The device is approved for use in combination with pemetrexed plus a platinum-based chemotherapy—pemetrexed plus cisplatin being the only approved therapy for patients with unresectabled MPM. In an effort to promote therapeutic innovation for rare diseases, the Humanitarian Device Exemption—the approval path for the NovoTTF-100L—does not require evidence of efficacy. However, data from the STELLAR trial, a prospective, single-arm trial of NovoTTF-100L plus chemotherapy in 80 patients with unresectable MPM showed no serious systemic adverse events for the device, with mild-to-moderate skin irritation being the most common adverse event. Of the 53 patients with epithelioid MPM, median OS was 21.2 months; median OS was 12.1 months for the 21 patients with non-epithelioid MPM. At 12 months, 62% of all patients were alive, and the ORR was 40%. The median PFS was 7.6 months. Further studies are needed to determine the efficacy of this device. Until phase III data are available to document superiority compared with chemotherapy alone, it is unclear how readily this device will be embraced in the United States.
Expanded Indication for Pembrolizumab
April 11, 2019—The U.S. Food and Drug Administration (FDA) expanded the approval of pembrolizumab in the first-line setting to patients with PD-L1 expression of ≥ 1% (tumor proportion score [TPS]), as determined by an FDA-approved assay. This includes patients with unresectable stage III NSCLC who are not candidates for definitive chemoradiation as well as patients with metastatic NSCLC. This indication excludes EGFR-/ALK-positive NSCLC.
Pembrolizumab is already approved as a single agent for the first-line treatment of patients with metastatic NSCLC and PD-L1 expression ≥ 50% (TPS) and as combined with platinum-based doublet (carboplatin and pemetrexed) regardless of PD-L1 expression. Recent approval was based on KEYNOTE-042, a randomized, multicenter, open-label, active-controlled trial conducted in 1,274 patients with stage III or IV NSCLC. Chemotherapy-naive patients with PD-L1 expression of > 1% (TPS) received either 200 mg IV of pembrolizumab every 3 weeks or investigator’s choice of a carboplatin- containing regimen with either pemetrexed or paclitaxel. Patients were stratified by ECOG performance status, geographic region, histology, and PD-L1 expression (TPS > 50% or TPS 1%-49%).
Median OS was 16.7 vs 12.1 months for pembrolizumab vs chemotherapy, respectively, in those patients with PD-L1 expression > 1% (HR 0.81; 95% CI: 0.71, 0.93; p = 0.0036). For those patients with PD-L1 expression ≥ 20%, the median OS was 17.7 months and 13.0 months, respectively (HR 0.77; 95% CI: 0.64, 0.92; p = 0.004). The estimated median OS was 20 months vs 12.2 months, respectively, for patients with PD-L1 expression > 50% (HR 0.69; 95% CI: 0.56, 0.85; p = 0.0006).
However, in an exploratory analysis, in the cohort of patients with PD-L1 expression of 1%-49%, the median OS was 13.4 months for pembrolizumab vs 12.1 months for chemotherapy (HR 0.92; 95% CI: 0.77, 1.11). Hence, the positivity of this trial was driven by the results observed in patients with tumor PD-L1 expression levels of 50% or higher.
Editor’s Note: The approval of single-agent pembrolizumab in patients with NSCLC with tumor PD-L1 expression levels of 1% to 49% remains controversial. As delineated by the exploratory analysis presented by Gilberto Lopes at the 2018 American Society of Clinical Oncology Annual Meeting, pembrolizumab did not result in an obvious survival advantage in this cohort compared to conventional platinum-based chemotherapy in treatment-naive patients. For now, based on the survival results of KEYNOTE-189 and KEYNOTE-407, pembrolizumab in combination with histology-appropriate chemotherapy remains the standard of comparison in this population. The National Clinical Trials Network in the United States is about to launch a phase III trial directly comparing single-agent pembrolizumab to combination pemetrexed/carboplatin and pembrolizumab in patients with advanced nonsquamous NSCLC with any degree of PD-L1 expression. –Corey Langer, MD, Editor
First New Treatment for SCLC in 20 Years
March 19, 2019—The U.S. Food and Drug Administration approved atezolizumab for the first-line treatment of patients with previously untreated extensive-stage SCLC. The approval was based on data from the global, randomized, double-blind, placebo-controlled, phase III IMpower133 trial, which was presented at the IASLC 2018 World Conference on Lung Cancer. Data showed that the addition of concurrent and maintenance atezolizumab to first-line carboplatin and etoposide resulted in a significant overall survival benefit. Median OS was 12.3 months with atezolizumab versus 10.3 months in the control arm (hazard ratio [HR] for death 0.70 [0.54, 0.91]). In addition, the 1-year overall survival rate was 51.7% in the atezolizumab group and 38.2% in the placebo group. The objective response rates were 60% and 64%, respectively. For more on the clinical and research implications resulting from IMpower133, read the IASLC Lung Cancer News article by the study author, Dr. Stephen V. Liu.
European Commission Approval of Atezolizumab in Combination with Bevacizumab and Chemotherapy
March 8, 2019—The European Commission approved the combination of atezolizumab, bevacizumab, and chemotherapy for first-line treatment of patients with metastatic non-squamous NSCLC. The approval was based on the significant survival benefit seen in the phase III IMpower150 trial for the combination of atezolizumab, bevacizumab, paclitaxel, and carboplatin (ABPC) compared with BPC alone (median overall survival [OS] = 19.8 vs 14.9 months; hazard ratio [HR] = 0.76; 95% CI: 0.63–0.96; p = 0.006). The combination has already been approved by the U.S. Food and Drug Administration. For a more nuanced perspective on the FDA’s approval, read the jointly authored perspective by the IASLC Lung Cancer News Editorial Group, “Thoughts on IMpower 150: Latest FDA Approval for Atezolizumab Misses the Mark.”
European Medicines Agency Approves Lorlatinib
March 1, 2019—The EMA has endorsed lorlatinib for the treatment of patients with ALK-positive advanced NSCLC that has progressed during prior kinase inhibitor therapy. The Committee for Medicinal Products for Human Use recommended granting of a conditional marketing authorization. Lorlatinib is recommended as monotherapy for patients who disease has progressed after first-line treatment with alectinib or ceritinib, or with crizotinib plus at least one other ALK-based TKI.
Lorlatinib was approved by the U.S. Food and Drug Administration in November 2018.
FDA Grants Priority Review to Roche’s Personalized Medicine Entrectinib
February 19, 2019—The U.S. Food and Drug Administration (FDA) accepted a New Drug Application (NDA) and granted Priority Review for entrectinib for treatment of patients with ROS-1 mutations and metastatic NSCLC. The FDA is expected to make a final decision regarding approval by mid-August 2019. Entrectinib also has received the FDA’s Breakthrough Therapy Designation, Priority Medicines designation by the European Medicines Agency (EMA), and Sakigake designation by the Japanese health authorities for the treatment of NTRK fusion-positive locally advanced or metastatic solid tumors in adult or pediatric patients who have experienced disease progression following prior therapies or have no other treatment options.
E-cigs Help Smokers Quit, Health Risks Unknown
January 30, 2019—British researchers found that e-cigarettes were more effective for smoking cessation than nicotine-replacement therapy when combined with behavioral therapy. The randomized trial, the results of which were published in The New England Journal of Medicine on January 30, found an almost double sustained abstinence rate after 1 year among the smokers randomly assigned to the e-cigarette group: 18.0% vs. 9.9% for nicotine-replacement products (relative risk 1.83; 95% CI: 130-2.58, p < 0.001). The study had several limitations, however, and the rate of continued e-cigarette use was fairly high. E-cigarettes may pose health risks, the severity of which are unknown, so long-term use could be problematic.
Genomic Profile Test Approved in Japan
December 27, 2018—The Ministry of Health, Labour, and Welfare (MHLW) approved the FoundationOne CDx as a comprehensive genomic profiling test for all solid tumors and as a companion diagnostic for patients with advanced cancer. Similar to the FDA approval in the United States, MHLW reimbursement coverage is expected to include MHLW-approved targeted therapies and immunotherapies therapeutic selection based on FoundationOne CDx results.
New Approval for Atezolizumab
December 6, 2018—The U.S. Food and Drug Administration (FDA) approved atezolizumab in combination with bevacizumab, paclitaxel, and carboplatin for management of metastatic nonsquamous NSCLC with no EGFR or ALK mutations in the first-line setting. Atezolizumab is also approved by the FDA for treatment of patients with metastatic NSCLC who experience disease progression during or following treatment with platinum-based chemotherapy, as well as for those patients who have EGFR or ALK mutations and have experienced disease progression during or after targeted therapy.
CheckMate-451 OS Endpoint Not Met
November 26, 2018—The phase III CheckMate-451 trial did not meet its primary endpoint of OS with combination nivolumab/ipilimumab vs. placebo as maintenance therapy for patients with extensive-stage SCLC with stable disease or response after first-line therapy with a platinum-based chemotherapy. Specific data are forthcoming, including data regarding the secondary endpoint of OS with single-agent nivolumab vs. placebo.
MYSTIC Fails to Meet Improved OS Endpoint
November 16, 2018—Phase III OS results were announced for MYSTIC, a randomized, open-label, multicenter, international trial of durvalumab monotherapy vs. durvalumab plus tremelimumab, an anti–CTLA-4 antibody, vs. platinum-based chemotherapy in treatment-naive patients with metastatic NSCLC. In the primary analysis of patients with PD-L1 expression on 25% or more of their cancer cells (as determined by the VENTANA PD-L1 Sp263 Assay), neither durvalumab alone nor its combination with tremelimumab significantly improved survival compared with chemotherapy. A hazard ratio of 0.76 (97.54% CI: 0.564-1.019; nominal p = 0.036) was observed for durvalumab alone; the combination’s HR was 0.85 (98.77% CI: 0.611-1.173; nominal p = 0.202).
Lorlatinib Approved for Second- or Third-Line Management of ALK-positive Metastatic NSCLC
November 2, 2018—The U.S. Food and Drug Administration granted accelerated approval to lorlatinib for patients with, ALK (+) metastatic or recurrent NSCLC with disease progression on crizotinib and at least one other ALK inhibitor or on alectinib or ceritinib as first ALK inhibitor therapy for metastatic or recurrent disease.
The accelerated approval was based on data from a nonrandomized, dose-ranging multicohort, multicenter study evaluating a subgroup of 215 patients with ALK-positive metastatic NSCLC who received prior treatment with one or more ALK kinase inhibitors (Study B7461001; NCT01970865). The major efficacy measures were overall response rate (ORR) and intracranial ORR, according to RECIST 1.1, as assessed by an independent central review committee.
The ORR was 48% (95% CI: 42-55), and the estimated median response duration was 12.5 months (95% CI: 8.4-23.7. Response rates were 4% for complete and 44% for partial responses. Of 89 patients with measurable CNS lesions (according to RECIST 1.1), the intracranial ORR was 60% (95% CI: 49-70), with 21% complete and 38% partial responses. The estimated median response duration was 19.5 months for those with measurable CNS lesions (95% CI: 12.4-not reached).
The most common adverse reactions (incidence ≥ 20%) were edema, peripheral neuropathy, cognitive effects, dyspnea, fatigue, weight gain, arthralgia, mood effects, and diarrhea.
Pembrolizumab/Carboplatin Plus Paclitaxel or Nab-Paclitaxel Approved for First-Line Treatment of Metastatic Squamous NSCLC
October 30, 2018—The U.S. Food and Drug Administration (FDA) approved pembrolizumab, an anti–PD-1 agent, in combination with carboplatin and either paclitaxel or nab-paclitaxel for the first-line treatment of patients with metastatic squamous NSCLC. The approval was based on the results of the KEYNOTE-407 trial, a pivotal phase III trial in which patients who received pembrolizumab in combination with carboplatin and either paclitaxel or nab-paclitaxel experienced significantly improved overall survival, regardless of PD-L1 expression status. Risk of death was reduced by 36% for patients receiving the pembrolizumab/ chemotherapy combination compared with chemotherapy alone (HR = 0.64; 95% CI: 0.49-0.85; p = 0.0017). This is the first approval for an anti–PD-1 regimen for this indication regardless of PD-L1 expression status.
Dacomitinib Approved as EGFR TKI
September 27, 2018—The U.S. Food and Drug Administration (FDA) approved dacomitinib for the first-line treatment of patients with metastatic NSCLC who have sensitizing EGFR mutations.
Approval was based on the ARCHER 1050 trial, which compared the safety and efficacy of dacomitinib to gefitinib in 452 patients with unresectable, metastatic NSCLC. Patients were required to have no prior therapy for metastatic disease or recurrent disease with a minimum of 12 months disease-free after completion of systemic non-EGFR TKI-containing therapy; an ECOG PS of 0 or 1; and EGFR exon 19 deletion or exon 21 L858R substitution mutations. Patients were randomly assigned to receive either 45 mg of dacomitinib orally once daily or 250 mg of gefitinib orally once daily until disease progression or unacceptable toxicity.
The trial showed that dacomitinib improved OS over gefitinib (34.1 vs. 26.8 months, p = 0.0438; HR 0.76, 95% CI [0.582-0.993]). For ARCHER 1050 details and for a more robust discussion of EGFR TKIs, read the article by Edgardo S. Santos Castillero, MD.
RET Inhibitor Wins Breakthrough Therapy Designation
September 5, 2018—The U.S. Food and Drug Administration n (FDA has granted LOXO-292, an investigational new agent, Breakthrough Therapy Designation for treatment of patients with RET-positive NSCLC who require systemic therapy and have experienced disease progression following treatment with a platinum-based chemotherapy and an anti–PD-1/PD-L1 therapy.
The designation was based on the phase I/II LIBRETTO-001 trial, an open-label, multi-center trial, which will be conducted in two parts: phase I (dose escalation) and phase II (dose expansion). The trial is currently enrolling patients. Patients are eligible if they have RET-fusion–positive NSCLC that has progressed on or if they have proven intolerant to available standard therapies.
New Standard of Care for First-line Management of EGFR mutation-positive NSCLC
August 21, 2018—The Japanese Ministry of Health, Labour, and Welfare approved osimertinib for first-line treatment of patients with inoperable or recurrent EGFR mutation-positive NSCLC. Approval was based on superior progression-free survival for osimertinib (18.9 months) compared with gefitinib or erlotinib (10.2 months), which was consistent across all subgroups, as found in the FLAURA trial. Osimertinib was also generally well tolerated, with grade 3 or higher adverse events occurring in 34% of patients (vs. 45% for gefitinib or erlotinib).
Japan is the 40th country to approve osimertinib for this indication.
Alectinib Approved for ALK-Positive NSCLC in China
August 20, 2018—The China National Drug Administration granted marketing authorization for alectinib as monotherapy for patients ALK-positive advanced NSCLC. This authorization follows on the heels of US Food and Drug Administration and European Medicines Agency approvals. Authorization was based on the phase III ALEX and ALESIA studies, as well as on two phase II studies assessing alectinib for treatment of patients with disease progression on or intolerance to crizotinib. Updated ALEX results were presented June 2018 at the American Society of Clinical Oncology meeting and showed that PFS more than tripled for patients who received alectinib vs. crizotinib (34.8 months vs. 10.9 months, respectively). Specifically regarding Asian patients with ALK-positive NSCLC, ALESIA found that alectinib reduced the risk of progression or death compared with crizotinib; this data will be submitted to the CDNA to complete a post-approval agreement. Results of ALESIA will be presented at an upcoming meeting.
Nivolumab Wins First Approval for Large Group of SCLC Patients
August 17, 2018—Nivolumab was granted approval by the US Food and Drug Administration for patients with metastatic SCLC whose cancer has progressed after platinum-based chemotherapy and at least one other line of therapy. This is the first approved therapy for this indication. Because this accelerated approval was based on data from the phase I/II CheckMate-032 for overall response rate and duration of response only, further confirmatory data may be required.
In CheckMate-032 109 patients received nivolumab after platinum-based chemotherapy and at least one other prior line of therapy. Of these, 13 responded (12%), with one complete response. In a separate analysis of 245 patients with SCLC and disease progression after chemotherapy, 45% had serious adverse reactions to nivolumab, the most common being fatigue, decreased appetite, musculoskeletal pain, dyspnea, nausea, diarrhea, constipation, and cough.
Lurbinectedin Receives Orphan Drug Designation
August 3, 2018—The U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation to lurbinectedin for the treatment of SCLC. Lurbinectedin (PM1183) is an investigational drug that inhibits RNA polymerase II, which is essential for transcription-addicted tumors. It is being investigated in the salvage setting for patients whose disease has progressed after initial treatment.
Europe Closes Gap to Approval of Anti–PD-1, Chemo Combination
July 30, 2018—The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion regarding approval of pembrolizumab, an anti–PD-1 therapy, in combination with pemetrexed and platinum chemotherapy (cisplatin or carboplatin) in the first-line setting for patients with metastatic nonsquamous NSCLC who do not harbor EGFR or ALK mutations, regardless of PD-L1 expression.
If approved, this would mark the first approval in Europe for anti–PD-1 therapy in combination with chemotherapy. Approval decisions are being based on OS and PFS data from KEYNOTE-189.
FDA Grants Priority Review for sBLA for Pembrolizumab
July 2, 2018—The U.S. Food and Drug Administration (FDA) granted a priority review for a supplemental biologics license application (sBLA) for pembrolizumab. The application is based on based on results of the phase III KEYNOTE-189 trial and seeks approval for pembrolizumab in combination with pemetrexed and platinum chemotherapy (carboplatin or cisplatin) as a first-line treatment for patients with metastatic NSCLC, regardless of PD-L1 expression. The FDA has set a Prescription Drug User Fee Act date of September 23, 2018.
CNDA Approves Nivolumab, China’s First PD-1 Inhibitor
June 15, 2018—the China National Drug Administration (CNDA) approved nivolumab injection for the treatment of locally advanced or metastatic NSCLC after prior platinum-based chemotherapy for patients without EGFR or ALK tumor mutations. This is China’s first and only PD-1 inhibitor. Approval was based on data from the phase III CheckMate-078 trial, in which 90% of the patients enrolled were Chinese.
ALEX Study Leads to Health Canada’s Approval of Alectinib
June 13, 2018—Health Canada approved alectinib as a monotherapy for the first-line treatment of patients with ALK-positive locally advanced (not amenable to curative therapy) or metastatic NSCLC. The approval was based on results from the phase III ALEX study, which demonstrated a reduced risk of disease progression or death by more than half (53%) with alectinib versus crizotinib. ALEX data also showed that alectinib reduced the risk of metastasis to the brain or CNS by 84% compared with crizotinib.
Medicare Approves Liquid Biopsy for NSCLC
June 12, 2018—The Guardant360® assay, a liquid biopsy by Guardant Health, Inc., has been approved for all fee-for-service Medicare patients with metastatic NSCLC who meet certain criteria. Approval was based on a recent study by Odegaard et al. of 10,593 patients with advanced solid tumors that showed high feasibility (> 99.6%) and clinical sensitivity (85.9%), with high potential actionability (72% with treatment or trial recommendations). This was especially true for patients with NSCLC; 34.5% of patient samples contained a directly targetable standard-of-care biomarker.
