Early discontinuation of checkpoint inhibition due to immune-related side effects does not have a significant impact on treatment efficacy

A course of treatment with checkpoint inhibitors Yervoy (ipilimumab) and Opdivo (nivolumab) for patients with unresectable or metastatic melanoma is every 3 weeks for a total of four doses. Almost forty percent of patients receiving this combined regimen discontinue treatment because of  immune-related adverse events. Continue reading →

Priming cancer for immunotherapy

Augmenting the responses to checkpoint inhibitors, which remove the “breaks” from the immune response, is a very popular area of research. The general concept is to turn immunologically cold tumors hot. For example, triple negative breast cancer (TNBC) is considered an immunologically cold tumor – anti-PD(L)1 therapy has shown responses of just 5-10%. Continue reading →

Recent immune checkpoint study failures do not dampen enthusiasm for the future

Immune checkpoint inhibitors are simply cancer wonder drugs about which we are learning more each day. Because they don’t work optimally in many patients and some even hyper-progress, the goal is to determine ways to expand their effectiveness to more patients. As such, the number of clinical studies with checkpoints and checkpoint combinations continues to grow.

Immune checkpoint inhibitors act by blocking the abrogating phase of the immune response that is necessary to prevent autoimmune disease – by prolonging the immune response against cancer, a more robust and prolonged immune response, which is required for effective cancer therapy, is achieved with checkpoint therapy.
