Evaluation of in vitro pharmacodynamic drug interactions of ceftazidime-avibactam with tigecycline in ESBL- and carbapenemase producing Escherichia coli and Klebsiella pneumoniae.

Background: Combination therapy offers a promising option to enhance efficacy and prevent resistance. A comprehensive and quantitative assessment of the last-resort combination of ceftazidime/avibactam and tigecycline is not available.

Objective: This study systematically investigated the pharmacodynamic interaction between ceftazidime/avibactam and tigecycline in clinical and isogenic Escherichia coli and Klebsiella pneumoniae strains harbouring genes that encode various carbapenemases or ESBLs.

Targeting MYCN upregulates L1CAM tumor antigen in MYCN-dysregulated neuroblastoma to increase CAR T cell efficacy.

Current treatment protocols have limited success against MYCN-amplified neuroblastoma. Adoptive T cell therapy presents an innovative strategy to improve cure rates. However, L1CAM-targeting CAR T cells achieved only limited response against refractory/relapsed neuroblastoma so far.

Pharmacokinetic/pharmacodynamic analysis of meropenem and fosfomycin combinations in in vitro time-kill and hollow-fibre infection models against multidrug-resistant and carbapenemase-producing Klebsiella pneumoniae.

Background: MDR Gram-negative bacteria, such as ESBL-producing and carbapenemase-producing Klebsiella pneumoniae, represent major global health threats. Treatment options are limited due to increasing resistance and slowed development of novel antimicrobials, making it necessary to apply effective combination therapies based on approved antibiotics.

Objectives: To quantitatively evaluate the synergistic potential of meropenem and fosfomycin against carbapenem-resistant K.

Drug Interaction Studies of Cabamiquine:Ganaplacide Combination against Hepatic .

New antimalarial combination therapies with novel modes of action are required to counter the emergence and spread of drug resistance against existing therapeutics. Here, we present a study to evaluate the preventive activity of a combination of clinical antimalarial drug candidates, cabamiquine and ganaplacide, that have multistage activity against the liver and blood stages of infection. Cabamiquine (DDD107498, M5717) inhibits parasite protein synthesis, and ganaplacide (KAF156) inhibits protein trafficking, blocks the establishment of new permeation pathways, and causes endoplasmic reticulum expansion.
