Immunotherapy Agents, Combinations to Compete for Frontline NSCLC

Excerpt:

“Immunotherapy agents, both as monotherapy and in combination, are emerging in the pipeline of non–small cell lung cancer (NSCLC) and could end up competing as frontline treatment for patients, explains Sukhmani Padda, MD.

“For example, the PD-1 inhibitor pembrolizumab (Keytruda) is the sole immunotherapy agent approved in the first-line setting for patients with NSCLC; however, many other immunotherapy agents and combination regimens are in development that are aimed at this line of therapy.”

Expert Tackles Efficacy of PD-L1 Testing for NSCLC in 2017

Excerpt:

“In 2017, a lung cancer diagnosis must be accompanied by biomarker testing, whether it be for a genomic alteration, such as EGFR, ALK, or ROS1, or the immune marker PD-L1, according to Daniel B. Costa, MD, PhD, MMSc.

“Moreover, even with FDA-approved agents designed to target these abnormalities or expression levels, researchers are still hoping to uncover additional markers and match novel therapies to them.”

Pembrolizumab Affords Long-Term Survival to One-Fourth of Selected Patients With NSCLC, Alternative Statistical Model Suggests

Excerpt:

“Statistical modeling of long-term survival from the KEYNOTE trials of the programmed cell death protein 1 (PD-1)–inhibitor pembrolizumab ­(Keytruda) estimates that one-quarter of appropriately selected patients with advanced non–small cell lung cancer (NSCLC) may attain long-term survival.

” ‘In the context of the pembrolizumab program, these are the furthest-out data that we have so far, and I think they represent a remarkable step forward,’ commented Matthew D. Hellmann, MD, of Memorial Sloan Kettering Cancer Center, New York, who presented the analysis at the 2017 ASCO-SITC (Society for Immunotherapy of Cancer) Clinical Immuno-Oncology Symposium.”

Innovative Immunotherapy Combo Tests IDO Inhibitor in Melanoma Trial

Excerpt:

“Investigators are looking into a novel immunotherapy combination that pairs the first-in-class IDO1 inhibitor epacadostat (INCB024360) with the checkpoint blockade agent pembrolizumab (Keytruda) in patients with unresectable or metastatic melanoma.

“The phase III KEYNOTE-252/ECHO-301 trial, which is enrolling at more than 120 locations, will randomize 600 patients in a 1:1 ratio to either epacadostat combined with pembrolizumab or pembrolizumab plus placebo (NCT02752074).”

Pembrolizumab Shows Promise in Treatment of Mesothelioma

Excerpt:

“Pembrolizumab, an antibody drug already used to treat other forms of cancer, can be effective in the treatment of the most common form of mesothelioma, according to a new study led by investigators from the Perelman School of Medicine at the University of Pennsylvania. The study, published this month in The Lancet Oncology, is the first to show a positive impact from checkpoint inhibitor immunotherapy drugs on this disease.

“Malignant pleural mesothelioma is a rare and aggressive cancer that represents about 90 percent of all malignant mesothelioma cases. It’s primarily caused by the inhalation of asbestos, a fiber commonly found in some forms of insulation, vinyl floor tiles, and other material. Tumors form in the pleura, a thin membrane of cells that line the lungs and chest wall. Most survive less than a year. This poor prognosis is partially due to the fact that most patients are not diagnosed until they are already at a late stage of the disease. The standard first-line therapy treatment involves chemotherapy, and currently there is no approved second-line therapy.”

Clinical Trials Test Treatments for High-Grade Brain Tumors


With a few exceptions, glioblastoma (GBM) remains largely incurable, and the U.S. Food and Drug Administration (FDA) has approved few treatments for the disease. Surgery (when feasible), radiation, and temozolomide are used in most patients. But even if a newly diagnosed tumor can be surgically excised, recurrences are too common.

In this blog post, I simply list some of the new treatments available in clinical trials for GBM and other high-grade brain tumors. Only drugs that have at least some preliminary results of activity are included, and the list is not meant to be fully comprehensive. The interested reader can judge for herself what might be of interest, keeping in mind that no single treatment is suitable or will work for all GBM patients. Continue reading…


FDA Grants Fast Track Designation to ImmunoPulse IL-12 for Melanoma

Excerpt:

“The FDA granted fast track designation to ImmunoPulse IL-12 for the treatment of metastatic melanoma that progressed during therapy with pembrolizumab or nivolumab.

“ImmunoPulse IL-12 (OncoSec Medical) is an intratumoral anticancer gene therapy that expresses interleukin-12 (IL-12).

“ ‘With the number of melanoma patients now being treated with either pembrolizumab (Keytruda, Merck) or nivolumab (Opdivo, Bristol Myers Squibb) in either the first- or second-line settings, there will be an increasing number of patients who will not respond to therapy,’ Punit Dhillon, president and CEO of OncoSec, said in a company-issued press release. ‘Thus, there is a clear need for treatments that can rescue these patients and help them benefit from these immunotherapies.’ ”

Pembrolizumab Long-Term Survival Rate Could Reach 25% in NSCLC

Excerpt:

“Treatment with pembrolizumab (Keytruda) could elicit long-term survival (LTS) rates of 21% to 25% for previously-treated patients with PD-L1–positive non–small cell lung cancer (NSCLC) compared with 3% to 4% for docetaxel, according to a statistical analysis of findings from the KEYNOTE-010 and -001 trials presented at the 2017 ASCO-SITC Symposium.

“Findings from the analysis shed light on the number of patients with advanced NSCLC expected to benefit for up to 70 months from pembrolizumab. According to survival statistics from the SEER database for 2006 to 2012, the 5-year survival rate was 4.3% for those with lung or bronchus cancer with distant metastases.”

The Next Few Years Will Bring Stunning Progress for TNBC, Expert Says

Excerpt:

“The treatment landscape for triple-negative breast cancer (TNBC) is transforming, experts say, with the potential additions of immunotherapy and PARP inhibitors. These agents are being explored both as monotherapy and in combination regimens with standard chemotherapy options.

“At the 2016 San Antonio Breast Cancer Symposium, treatment with pembrolizumab (Keytruda) continued to show a consistent durable benefit with an additional year of follow-up for heavily pretreated patients with recurrent PD-L1–positive TNBC, according to findings from the phase Ib KEYNOTE-012 trial.”
