“In patients with metastatic triple negative breast cancer (TNBC), turning a nonimmunogenic (“cold”) tumor into an immunogenic (“hot”) tumor appears to be feasible, thereby improving sensitivity to immune therapy with nivolumab (Opdivo).
“In a phase II study of 50 patients with metastatic TNBC who received palliative chemotherapy, priming the immune system with low-dose chemotherapy for 2 weeks or radiation therapy before starting nivolumab resulted in a best objective response rate (ORR) of 24%, announced Marleen Kok, MD, at the 2017 ESMO Congress in Madrid.”
“In a head-to-head comparison of two immunotherapy drugs used to prevent relapse in certain patients with advanced melanoma, one treatment was the clear winner — and it’s not the one that most people get.
“The international study, released Sunday, involved 900 patients whose tumors were removed by surgery but who remained at high risk of recurrence of melanoma, an often aggressive form of skin cancer.”
“The European Society for Medical Oncology (ESMO) 2017 Congress is just around the corner, and we can already say with confidence that there will be many provocative presentations, including several that are poised to change practice. At this point, we can only rely on the abstracts and press releases for several of these, but here are my early impressions on the top five presentations in lung cancer for ESMO 2017.”
“The combination of the programmed death receptor 1 (PD-1) inhibitor nivolumab at a reduced dose (1 mg/kg) with the cytotoxic T-lymphocyte antigen 4 (CTLA-4) inhibitor ipilimumab at standard dose (3 mg/kg) for four doses followed by standard-dose nivolumab alone is a standard of care for patients with advanced, previously untreated melanoma. This is based on results from the phase III CheckMate-067 trial that confirmed combination therapy is significantly more effective than single-agent nivolumab or ipilimumab. However, improvement in efficacy is associated with increased treatment-related grade 3/4 adverse events and treatment discontinuation in nearly 40% of patients.”
“Matthew D. Hellmann, MD, medical oncologist, Memorial Sloan Kettering Cancer Center, discusses the CheckMate-032 study, which explored nivolumab (Opdivo) with or without ipilimumab (Yervoy) for patients with small cell lung cancer (SCLC).”
“Bristol-Myers got a much-needed boost with the earlier-than-expected news that Opdivo beat out Yervoy in a Phase III study focused on a particular niche for adjuvant melanoma therapy. And an analyst who’s been following the data says it could be worth a billion dollars in added annual sales.
“The big biotech says an interim analysis of Checkmate-238 provided researchers with proof that the PD-1 drug outperformed Yervoy, Bristol-Myers’ CTLA-4 drug, among advanced Stage IIIb or IV patients, cutting the recurrence rate for those who have undergone surgery. There are no bottom line numbers in the statement, but Bristol-Myers says they’ll be able to release data at an upcoming conference to show that Opdivo provided a significantly lower risk of disease recurrence.”
There are many hopes that combining immune checkpoint inhibitor drugs, or combining them with drugs of other types (immunotherapy, targeted therapy, or chemotherapy) is the future of treatment for many kinds of cancer. Literally hundreds of clinical trials are actively exploring these combinations, and melanoma is the cancer for which trials of this type abound. Last month, the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago featured just a few presentations in this area, apparently because it is too early to report results from the many ongoing trials with drug combinations.

“Patients with melanoma continued to experience tumor response to nivolumab monotherapy when treated beyond progression, according to a pooled analysis of data from the CheckMate 066 and CheckMate 067 studies.
” ‘The results of this analysis suggest that continued treatment with nivolumab [Opdivo, Bristol-Myers Squibb] may be an option to achieve further apparent clinical benefit in some patients with advanced melanoma,’ Georgina V. Long, PhD, BSc, MBBS, FRACP, chair of melanoma medical oncology and translational research at Melanoma Institute Australia and Royal North Shore Hospital of The University of Sydney in Sydney, Australia, and colleagues wrote.”
“Findings from a phase III clinical trial for advanced lung cancer patients could help oncologists better predict which patients are likely to receive the most benefit from immunotherapy as a first-line treatment based on the unique molecular characteristics of their tumor, according to a new study reported by a global team led by David Carbone, MD, PhD, of The Ohio State University Comprehensive Cancer – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).
“In this study, researchers compared the effectiveness of the immunotherapy drug nivolumab (pronounced ‘nye VOL ue mab,’ marketed at Opdivo), with standard-of-care chemotherapy in 541 patients with previously untreated or recurrent non-small cell lung cancer (NSCLC) that expressed PDL-1 antibodies.”
