Nivolumab is an immune checkpoint inhibitor (ICI) that selectively inhibits programmed cell death protein 1 activation, restoring antitumor immunity. ICIs are indicated for various types of advanced solid tumors; however, not all patients benefit from them, and tools could be used in the clinic to predict response treatment represent unmet need. Here we describe development a new population pharmacokinetic (PPK) model treated with nivolumab clinical trials.

Antibody-Drug Conjugates (ADCs) represent an innovative class of potent anti-cancer compounds that are widely used in the treatment hematologic malignancies and solid tumors. Unlike conventional chemotherapeutic drug-based therapies, mainly associated with modest specificity therapeutic benefit, three key components form ADC (a monoclonal antibody bound to a cytotoxic drug via chemical linker moiety) achieve remarkable improvement terms targeted killing cancer cells and, while sparing healthy tissues, reduction systemic side effects caused by off-tumor toxicity. Based on their beneficial mechanism action, 15 ADCs have been approved date market approval Food Drug Administration (FDA), European Medicines Agency (EMA) and/or other international governmental agencies for use clinical oncology, hundreds undergoing evaluation preclinical phases.

Cancer stem cells (CSCs) have emerged as key contributors to tumor initiation, growth, and metastasis. In addition, CSCs play a significant role in inducing immune evasion, thereby compromising the effectiveness of cancer treatments. The reciprocal communication between microenvironment (TME) is observed, with TME providing supportive niche for CSC survival self-renewal, while CSCs, turn, influence polarization persistence TME, promoting an immunosuppressive state. Consequently, these interactions hinder efficacy current therapies, necessitating exploration novel therapeutic approaches modulate target CSCs. this review, we highlight intricate strategies employed by evade surveillance develop resistance therapies.

Abstract In the past decade, chimeric antigen receptor (CAR)-T cell therapy has emerged as a promising immunotherapeutic approach for combating cancers, demonstrating remarkable efficacy in relapsed/refractory hematological malignancies both pediatric and adult patients. CAR-natural killer (CAR-NK) complements CAR-T by offering several distinct advantages. CAR-NK cells do not require HLA compatibility exhibit low safety concerns. Moreover, are conducive to “off-the-shelf” therapeutics, providing significant logistic advantages over cells. Both have shown consistent results malignancies.
