Flu Vaccine in Lung Cancer Patients Could Increase Immunotherapy Toxicities

Excerpt:

“Seasonal influenza vaccination resulted in increased risk of immune-related adverse events (AEs) in lung cancer patients treated with PD-1/PD-L1 checkpoint inhibitors in a small study. However, the risks of the flu itself may still outweigh the risks associated with vaccination.

” ‘Use of immune checkpoint inhibitors is now standard clinical practice for many oncology patients, and these same patients—particularly those with lung cancer—also face increased risk for complications from influenza,’ said Sacha Rothschild, MD, PhD, of University Hospital Basel in Switzerland, in a press release. ‘Although routine influenza vaccination has long been recommended for cancer patients, there are concerns that it might trigger an exaggerated immune response in this subgroup receiving checkpoint inhibitors.’ ”

Triple-Negative Breast Cancer Patients Who Responded to Immunotherapy Had Long-Term Survival Benefit

Excerpt:

“Among patients with metastatic triple-negative breast cancer (TNBC) who were treated with the anti-PD-L1 cancer immunotherapy atezolizumab (Tecentriq), those who responded to the medicine lived significantly longer (overall survival) compared with those who did not respond, according to data from a phase I clinical trial presented here at the AACR Annual Meeting 2017, April 1-5.

” ‘Triple-negative is an aggressive subtype of breast cancer often affecting younger women and, unfortunately, the current options for metastatic disease remain limited,’ said Peter Schmid, MD, PhD, director of the St. Bartholomew’s Breast Centre at St. Bartholomew’s Hospital and Barts Cancer Institute in London.”

Metastatic Melanoma: Not Quite Curable…But Getting There


By 2050, the number of deaths due to malignant melanoma in the U.S. could be three times lower than peak levels reached before 1960. Researchers presented the data behind this prediction at the 2017 European Cancer Congress in January.

It is unclear how much of this anticipated decline in deaths can be attributed to the availability of new, effective treatments. However, it is obvious that much-increased awareness of sunlight exposure as the single factor most responsible for the development of skin melanoma has contributed to lower incidence of the disease.

In any case, the armament of treatments available for metastatic melanoma is currently such that this diagnosis has transformed from being almost universally fatal (even just a few years ago) into a being largely treatable. Since 2011, the U.S. Food and Drug Administration (FDA) has approved eight new drugs for melanoma. Continue reading…


Nab-Paclitaxel Paired With Anti-PD-L1 Immunotherapies in TNBC Studies

Excerpt:

“Combination regimens that pair nab-paclitaxel (Abraxane) with PD-L1 checkpoint blockade immunotherapy agents are emerging as a robust area of investigation in triple-negative breast cancer (TNBC), bolstered by clinical trial results that establish the chemotherapeutic agent as an effective partner for other therapies.

“Although nab-paclitaxel has been combined in some studies with other chemotherapies, the focus is shifting to regimens that include immunotherapies as the efficacy of that approach continues to grow. Nab-paclitaxel, an albumin-bound form of paclitaxel, is indicated for patients with metastatic breast cancer after prior chemotherapy.”

Super Patient: Peter Fortenbaugh Faces the Uncertainty of Pioneering Melanoma Treatment


In spring of 2014, Peter Fortenbaugh noticed what appeared to be a tick that had bitten his lower calf. “It turned out not to be a tick, but it didn’t really go away,” he says.

The spot began to grow and bulge, and in October, Peter showed it to his primary care doctor, who referred him to a dermatologist to remove it. At the time, Peter recalls, it did not occur to him that the growth could be serious.

“I was actually very concerned about skin cancer because I spent a lot of time out in the sun sailing,” Peter says. “I put on a tremendous amount of sunscreen and protection, but never on my legs…I never connected the dots.”

However, a biopsy of the growth came back positive for melanoma. Peter, who lives in Palo Alto, California, with his wife and three children, immediately reached out to several doctors in the San Francisco Bay Area, and all had the same advice: “Take it out, take a biopsy.” Continue reading…


Immunotherapy Drug Gives Non-Small-Cell Lung Cancer Patients Extra Four Months of Life

Excerpt:

“Patients with advanced non-small-cell lung cancer survive four months longer with fewer side effects on an immunotherapy drug called atezolizumab compared to chemotherapy, according to a phase 3 clinical trial published in The Lancet.

“The trial enrolled 1225 advanced non-small-cell lung cancer patients who have no more treatment options, but this study used an early analysis of the first 850 patients from the trial. Half of the group were given atezolizumab and the other half were given docetaxel chemotherapy, which is the standard treatment for advanced non-small-cell lung cancer.

“Patients given atezolizumab – a drug that blocks the programmed death ligand 1 (PD-L1) protein – survived for an average of 13.8 months, compared with 9.6 months for those on chemotherapy.”

Early Results Positive for First-Line Avelumab in NSCLC

Excerpt:

“Treatment with first-line avelumab yielded promising clinical benefit and durable antitumor activity in patients with advanced non–small cell lung cancer (NSCLC), according to a presentation at the IASLC 17th World Conference on Lung Cancer.

“After a median follow-up of 13 weeks, the objective response rate with the anti-PD-L1 immunotherapy agent was 22.4% (95% CI, 16.2-29.8) and the median progression-free survival (PFS) was 17.6 weeks (95% CI, 11.6-23.6) among 156 patients who participated in one of the NSCLC cohorts of the wide-ranging JAVELIN Solid Tumor trial, Claire Verschraegen, MD, director, The University of Vermont Cancer Center, said in describing early analysis data at the conference in Vienna.”

Study Characterizes Pneumonitis Risk With Immunotherapeutic Agents

Excerpt:

“Pneumonitis occurs in approximately 5% of cancer patients treated with anti–programmed death 1 (PD-1)/programmed death ligand 1 (PD-L1) immunotherapy agents, according to a new analysis. The complication tends to be low grade and easily resolved, though it can worsen and result in death in rare cases.

“ ‘One of the remarkable characteristics of anti–PD-1/PD-L1 monoclonal antibodies is their relatively mild toxicity profile,’ wrote study authors led by Matthew D. Hellmann, MD, of Memorial Sloan Kettering Cancer Center in New York. ‘However, immune-related adverse events can occur and may be severe.’ Pneumonitis is one such immune-related adverse event, and it accounted for several deaths in early trials of these agents.”
