drug resistance

Using corrected TMB and other variables allowed Johns Hopkins researchers to more accurately predict response to immune checkpoint blockade in lung cancer.

The drug is designed to tackle C797S resistance mutations that arise in NSCLC patients after treatment with third-generation tyrosine kinase inhibitors.

Researchers tested the combined treatment in mice, after detecting increased PAK4 expression and reduced immune infiltration in melanoma patients with poor anti-PD-1 response.

A new study suggests that colorectal cancers increase their mutation rate to dodge treatment in a manner that mirrors microbial resistance mechanisms.

A modified analogue of rucaparib is being used to track PARP-1 expression in PARP inhibitor-treated patients with pancreatic, breast, prostate, and other cancer types.

Researchers used Mission Bio's Tapestri assay to identify and monitor the evolution of cancer mutations in acute myeloid leukemia in response to targeted treatment.

A CTC and ctDNA analysis suggests that the number of alterations affecting the androgen receptor can offer survival insights for TP53 mutation-free advanced cancer cases.

Mismatch repair-deficient tumors with many insertion-deletion mutations and enhanced microsatellite instability responded better to anti-PD-1 immunotherapy.

The researchers also reported that combining an ER-directed therapy with an irreversible HER2 kinase inhibitor could overcome resistance.

The researchers found that most advanced EGFR-mutant lung cancer patients harbored changes in an average of two to three other oncogenes.
