PF-03084014, a γ-secretase inhibitor, was tested against the PPTP in vitro cell line panel (1.0 nM to 10 μM) and against the in vivo xenograft panels (administered orally twice daily on Days 1-7 and 15-21). PF-03084014 demonstrated limited in vitro activity, with no cell line achieving ≥50% inhibition. PF-03084014 induced significant differences in EFS distribution in 14 of 35 (40%) solid tumor xenografts, and 1 of 9 ALL xenografts (which lacked a NOTCH1 mutation), but objective responses were not observed. PF-03084014 demonstrated limited single agent activity in vitro and in vivo against the pediatric preclinical models studied.

Non-small cell lung cancer (NSCLC) continues to be the number one cause of cancer-related death for both women and men worldwide. More information needs to be gathered to understand the interactions between cancer cells, the immune system, the microenvironment within each tumor, and the host tissue to develop more effective treatment modalities. Reported here is a simple, repeatable method for inducing cancer within the mouse lung, allowing for the monitoring of tumor growth from early to late-stage disease.

Congenital heart disease (CHD) is the most common congenital anomaly. While surgical and interventional advancements have improved survival, the management of associated complications and comorbidities remains complex and would benefit from a personalised approach that more accurately predicts individualised risks and prognoses. Recently, next-generation sequencing has uncovered diverse genetic factors, including epigenetic modifications, somatic mosaicism and regulatory non-coding variants.

Introduction: Preclinical and clinical study data show that combining bedaquiline (B or BDQ), moxifloxacin (M), and pyrazinamide (Z), known as BMZ, has potent antimicrobial activity that might shorten treatment duration for drug-susceptible pulmonary tuberculosis.
Methods/design: We describe the design of Tuberculosis Trials Consortium (TBTC) Study 38/CRUSH-TB (NCT05766267), an open-label multicenter international randomized controlled phase 2C trial that compares two four-month regimens, BMZ plus rifabutin (Rb) (2BMZRb/2BMRb) or BMZ plus delamanid (D or DLM) (2BMZD/2BMD), with standard 6-months isoniazid, rifampin, pyrazinamide, and ethambutol (HRZE). All drugs are administered seven days per week, under direct observation, at least five days per week.

Antibody-mediated rejection is a leading cause of allograft failure and mortality in pediatric solid organ transplant recipients. Current apheresis systems require large blood volumes and are primarily designed for adults, making them unsuitable for children and small animals. These systems often indiscriminately remove both harmful and protective antibodies, increasing the risk of complications such as life-threatening infections.

Host - microbiome interactions are central to Crohn'sdisease (CD) pathogenesis; yet the early metabolic alterations that precededisease onset remain poorly defined. To explore preclinical metabolicsignatures of CD, we analyzed baseline serum metabolomic profiles in a nestedcase-control study within the Crohn's and Colitis Canada - Genetics, Environment, Microbiome (CCC-GEM) Project, a prospective cohort of 5,122 healthyfirst-degree relatives (FDRs) of CD patients. We included 78 individuals wholater developed CD and 311 matched FDRs who remained disease-free.
