Article Synopsis
  • Axatilimab is a monoclonal antibody that targets CSF-1R, approved for treating chronic graft-versus-host disease (cGVHD) and being researched for other conditions like idiopathic pulmonary fibrosis.
  • A study involving 325 participants investigated the drug's pharmacokinetics (PK) and pharmacodynamics (PD), showing that it reduces certain immune cell levels, which affects enzyme levels in the bloodstream.
  • The final PK/PD model, based on complex math involving differential equations, identified several factors influencing axatilimab's effectiveness and helped shape dosing strategies for cGVHD patients.

Background And Objectives: The oral, potent, and highly selective activin receptor-like kinase 2 (ALK2) inhibitor zilurgisertib (INCB000928) is in development as a treatment for fibrodysplasia ossificans progressiva (FOP), and for anemia due to myelofibrosis, myelodysplastic syndromes, and multiple myeloma. Saliva is an attractive alternative to blood for drug monitoring and pharmacokinetic analysis, as it is non-invasive to retrieve. This is beneficial for patients, such as those with FOP, for whom blood draws can be challenging due to soft tissue damage susceptibility that can cause progressive heterotopic ossification, and for whom tourniquet time and blood draws must be minimized.

Physical impairments following cancer treatment have been linked with the toxic effects of these treatments on muscle mass and strength, through their deleterious effects on skeletal muscle mitochondrial oxidative capacity. Accordingly, we designed the present study to explore relationships of skeletal muscle mitochondrial oxidative capacity with physical performance and perceived cancer-related psychosocial experiences of cancer survivors. We assessed skeletal muscle mitochondrial oxidative capacity using in vivo phosphorus-31 magnetic resonance spectroscopy (P MRS), measuring the postexercise phosphocreatine resynthesis time constant, τPCr, in 11 post-chemotherapy participants aged 34-70 years.

Article Synopsis
  • Survivorship care plans (SCPs) are documents that help cancer survivors by explaining what follow-up tests they need based on their cancer treatment.
  • In a study of patients with breast, colorectal, or prostate cancer, researchers looked at tests performed after patients received their SCPs to see if any were unnecessary and followed guidelines against them.
  • They found that many tests (especially for breast cancer) were done even though they weren't needed according to the guidelines, showing a need for better education and practices among healthcare providers.

Biologics are increasingly being co-developed in combination or as novel constructs like bispecific antibodies (BsAbs) with the goal of targeting multiple, non-redundant mechanisms of action. Rational design of combinations and dual-targeting approaches that consider disease complexities have the potential to improve efficacy and safety, to increase duration of clinical benefit, and to minimize clinical resistance mechanisms. Here we summarize examples of BsAbs and biologic combinations that have been approved by health authorities and present drug development considerations when deciding between these two strategies.

Article Synopsis
  • Many patients stop endocrine therapy for breast cancer due to side effects, making it tough to identify at-risk individuals.
  • Research established the minimal important difference (MID), which highlights clinically significant changes in patient-reported outcomes (PROs).
  • In a study of 321 women undergoing endocrine therapy, a correlation was found between worsening PRO scores and the likelihood of discontinuation, particularly linked to endocrine symptoms and sleep disturbances.*

Background: Retrospective studies have suggested a potential risk of hyperprogressive disease (HPD) in patients receiving immune checkpoint inhibitors (ICIs). We compared the incidence of HPD during treatment with nivolumab±ipilimumab versus natural tumor progression with placebo in post hoc analyses of two randomized, double-blind clinical trials.

Methods: ATTRACTION-2 randomized patients with advanced gastric or gastroesophageal junction cancer (GC/GEJC) and progression on ≥2 prior regimens to nivolumab 3 mg/kg Q2W or placebo.

Background: Although racial disparities in breast cancer (BC) mortality have been well documented in the United States, little is known about the impact of coexisting cardiovascular disease (CVD) and other clinical factors on Black-White survival disparities after the diagnosis of BC. This study examined the associations of race, CVD, and clinical factors at diagnosis with the hazard of BC and CVD-related mortality among patients with BC identified from the Maryland Cancer Registry.

Methods: A total of 36,088 women (25,181 Whites and 10,907 Blacks) diagnosed with incident invasive BC between 2007 and 2017 were included.
