Safety and Tolerability of Letetresgene Autoleucel (Lete-cel; GSK3377794): Pilot Studies in Patients With Advanced Non-Small Cell Lung Cancer.

Purpose: To evaluate safety, tolerability, and anti-tumor response of lete-cel, genetically modified autologous T-cells expressing a T-cell receptor specific for NY-ESO-1/LAGE-1a shared epitope, alone or in combination with pembrolizumab, in human leukocyte antigen HLA-A*02-positive (HLA-A*02:01-, HLA-A*02:05-, and/or HLA-A*02:06-) patients with New York esophageal squamous cell carcinoma 1 (NY-ESO-1)- and/or LAGE-1a-positive non-small cell lung cancer (NSCLC).

Experimental Design: Study 208749 was a single-arm study of lete-cel alone. Study 208471 was a multi-arm study of lete-cel alone or in combination with pembrolizumab in patients with advanced or recurrent NSCLC.

Randomized trial of anetumab ravtansine and pembrolizumab compared to pembrolizumab for mesothelioma.

Purpose: The mesothelin-targeting antibody-drug conjugate anetumab ravtansine was evaluated in combination with the programmed cell death-1 (PD-1) inhibitor pembrolizumab based on the common expression of mesothelin and reports of activity in mesothelioma.

Patients And Methods: A phase 1 safety run-in of the combination of anetumab ravtansine (6.5 mg/kg iv q3weeks) and pembrolizumab (200 mg, IV q3weeks) was conducted, followed by a phase 2 randomization to the combination or pembrolizumab alone at medical centers across the United States and Canada in the National Cancer Institute's Experimental Therapeutics Clinical Trials Network.

A phase II clinical trial evaluating the safety and efficacy of durvalumab as first line therapy in advanced and metastatic non-small cell lung cancer patients with Eastern Cooperative Oncology Group performance status of 2.

Background: Approximately 30-40% of patients with advanced and metastatic non-small cell lung cancer (NSCLC) present with an impaired performance status (PS). There are limited prospective data on the safety and efficacy of durvalumab in these patients.

Methods: In this single-arm phase II clinical trial (NCT02879617), patients with previously untreated Stage IIIB/IV NSCLC and ECOG PS of 2 received durvalumab 1500 mg every 28 days until progression or unacceptable toxicity.

Combination of Itacitinib or Parsaclisib with Pembrolizumab in Patients with Advanced Solid Tumors: A Phase I Study.

Purpose: This phase Ib open-label, multicenter, platform study (NCT02646748) explored safety, tolerability, and preliminary activity of itacitinib (Janus kinase 1 inhibitor) or parsaclisib (phosphatidylinositol 3-kinase δ inhibitor) in combination with pembrolizumab [programmed death-1 (PD-1) inhibitor].

Experimental Design: Patients with advanced or metastatic solid tumors with disease progression following all available therapies were enrolled and received itacitinib (Part 1 initially 300 mg once daily) or parsaclisib (Part 1 initially 10 mg once daily; Part 2 all patients 0.3 mg once daily) plus pembrolizumab (200 mg every 3 weeks).

Tumor cell p38 inhibition to overcome immunotherapy resistance.

Patients with tumors that do not respond to immune-checkpoint inhibition often harbor a non-T cell-inflamed tumor microenvironment, characterized by the absence of IFN-γ-associated CD8 T cell and dendritic cell activation. Understanding the molecular mechanisms underlying immune exclusion in non-responding patients may enable the development of novel combination therapies. p38 MAPK is a known regulator of dendritic and myeloid cells however a tumor-intrinsic immunomodulatory role has not been previously described.

Guidance for clinicians and patients with non-small cell lung cancer in the time of precision medicine.

Major advances in the diagnosis and treatment of non-small cell lung cancer (NSCLC) have resulted in a sharp decline in associated mortality rates, thereby propelling NSCLC to the forefront of precision medicine. Current guidelines recommend upfront comprehensive molecular testing for all known and actionable driver alterations/biomarkers (, , , , , , , , [], and PD-L1), especially in advanced disease stages, as they significantly influence response to therapy. In particular, hybrid capture-based next-generation sequencing (HC-NGS) with an RNA fusion panel to detect gene fusions is a veritable requirement at both diagnosis and progression (resistance) of any-stage non-squamous adenocarcinoma NSCLCs.

Emerging therapeutic strategies for enhancing sensitivity and countering resistance to programmed cell death protein 1 or programmed death-ligand 1 inhibitors in non-small cell lung cancer.

The availability of agents targeting the programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) immune checkpoint has transformed treatment of advanced and/or metastatic non-small cell lung cancer (NSCLC). However, a substantial proportion of patients treated with these agents do not respond or experience only a brief period of clinical benefit. Even among those whose disease responds, many subsequently experience disease progression.

Overcoming -Mutant Lung Cancer.

More than 50 years after the discovery of RAS family proteins, which harbor the most common activating mutations in cancer, the U.S. Food and Drug Administration approved the first direct allele-specific inhibitor of mutant in lung cancer.

Short communication: The activity of brigatinib in patients with disease progression after next generation anaplastic lymphoma tyrosine kinase inhibitors and an exploratory analysis of circulating tumor DNA.

Background: Brigatinib, a second generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI), is central nervous system (CNS) penetrant and active against anaplastic lymphoma kinase (ALK) resistance mutations. We prospectively studied the activity of brigatinib in patients with disease progression after second generation ALK TKIs.

Methods: Patients with stage IIIB/IV ALK + non-small cell lung cancer (NSCLC), and progressive disease after second ALK TKIs were eligible.

Durvalumab plus tremelimumab alone or in combination with low-dose or hypofractionated radiotherapy in metastatic non-small-cell lung cancer refractory to previous PD(L)-1 therapy: an open-label, multicentre, randomised, phase 2 trial.

Background: Patients with non-small-cell lung cancer (NSCLC) that is resistant to PD-1 and PD-L1 (PD[L]-1)-targeted therapy have poor outcomes. Studies suggest that radiotherapy could enhance antitumour immunity. Therefore, we investigated the potential benefit of PD-L1 (durvalumab) and CTLA-4 (tremelimumab) inhibition alone or combined with radiotherapy.

IMpower150 Final Exploratory Analyses for Atezolizumab Plus Bevacizumab and Chemotherapy in Key NSCLC Patient Subgroups With EGFR Mutations or Metastases in the Liver or Brain.

Introduction: Final overall survival (OS) analyses are presented for EGFR mutations and liver or brain metastases subgroups in the phase 3 IMpower150 study (NCT02366143) evaluating atezolizumab plus bevacizumab plus carboplatin and paclitaxel (ABCP) or atezolizumab plus carboplatin and paclitaxel (ACP) versus bevacizumab plus carboplatin and paclitaxel (BCP).

Methods: Overall, 1202 patients (intention-to-treat population) with chemotherapy-naive, metastatic, nonsquamous NSCLC were randomized to ABCP, ACP, or BCP. Patients with treated, stable brain metastases were permitted.

Phase 2 Study of Dabrafenib Plus Trametinib in Patients With BRAF V600E-Mutant Metastatic NSCLC: Updated 5-Year Survival Rates and Genomic Analysis.

Introduction: Dabrafenib plus trametinib was found to have robust antitumor activity in patients with BRAF V600E-mutant metastatic NSCLC (mNSCLC). We report updated survival analysis of a phase 2 study (NCT01336634) with a minimum of 5-year follow-up and updated genomic data.

Methods: Pretreated (cohort B) and treatment-naive (cohort C) patients with BRAF V600E-mutant mNSCLC received dabrafenib 150 mg twice daily and trametinib 2 mg once daily.

Macrovasculature and positron emission tomography (PET) standardized uptake value in patients with lung cancer.

Purpose: To investigate the relationship between macrovasculature features and the standardized uptake value (SUV) of positron emission tomography (PET), which is a surrogate for the metabolic activity of a lung tumor.

Methods: We retrospectively analyzed a cohort of 90 lung cancer patients who had both chest CT and PET-CT examinations before receiving cancer treatment. The SUVs in the medical reports were used.

Crizotinib in Patients With MET-Amplified NSCLC.

Introduction: MET amplification is a rare, potentially actionable, primary oncogenic driver in patients with NSCLC.

Methods: The influence of MET amplification on the clinical activity of the ALK, ROS1, and MET inhibitor, crizotinib (250 mg twice daily), was examined in patients with NSCLC (NCT00585195) who were enrolled into high (≥4 MET-to-CEP7 ratio), medium (>2.2 to <4 MET-to-CEP7 ratio), or low (≥1.

Phase IB Study of Osimertinib in Combination with Navitoclax in -mutant NSCLC Following Resistance to Initial Therapy (ETCTN 9903).

Purpose: Osimertinib is an effective therapy in -mutant non-small cell lung cancer (NSCLC), but resistance invariably develops. Navitoclax is an oral inhibitor of BCL-2/BCL-xL that has exhibited synergy with osimertinib in preclinical models of -mutant NSCLC. In hematologic malignancies, BCL-2 family inhibitors in combination therapy effectively increase cellular apoptosis and decrease drug resistance.

Immune Checkpoint Blockade in Oncogene-Driven Non-Small-Cell Lung Cancer.

Patients with oncogene-driven lung cancer have limited therapeutic options after progressing on their targeted tyrosine kinase inhibitor (TKI) therapy. Given the growing role of immune checkpoint inhibitor (ICI) therapy in the treatment of lung cancer, oncogene-driven cancer has warranted further evaluation regarding ICI therapy. However, initial ICI studies have suggested that ICI monotherapy is not only lacking in efficacy, but that it may be less tolerable in oncogene-driven non-small-cell lung cancer (NSCLC).

Nab-paclitaxel in older patients with non-small cell lung cancer who have developed disease progression after platinum-based doublet chemotherapy.

Background: The selection of later-line treatment for older patients with AJCC (version 7) stage IV non-small cell lung cancer (NSCLC) remains controversial. Nanoparticle albumin-bound (nab)-paclitaxel is approved with carboplatin for the first-line treatment of patients with NSCLC and subgroup analysis of phase 3 data has suggested superior survival in older patients.

Methods: The authors conducted a phase 2 study of nab-paclitaxel in 42 patients aged ≥70 years who had been treated previously with a platinum doublet regimen; patients also could have received a PD-1 inhibitor.
