Preclinical efficacy models of Chemotherapy-induced Pain
Neurotoxicity and peripheral neuropathy are standard side effects of agents used for chemotherapy. A side effect is peripheral neuropathy and is a limiting factor for dose levels required for anti-tumor effects.

CIPN In Vitro Screening Assay
A hallmark of degeneration is the blebbing of neurites, which is when neurites begin disassembly and degeneration. The neurodegeneration index (NI) compares the relative area of neurites and the number of neurites.
The CIPN in vitro screening assay overview: Dorsal root ganglion (DRG) neurons were cultured from adult rats. Cultures are treated for 5 days with a chemotherapeutic agents followed by treatment with compound. Cultures are stained with beta-tubulin III antibody and measured for neurodegeneration index.
The assays are ideal for screening compounds prior to efficacy in in vivo studies.

Chemotherapy-induced Peripheral Neuropathy
- Species: Mouse or Rat
- Duration: 14-21 days
- Readouts: tactile/mechanical allodynia, thermal hyperalgesia
- Endpoints: histology, biomarker analysis (protein or mRNA levels in sciatic nerve or serum/plasma)
Assessments
MD Biosciences incorporates a range of in vivo measures and endpoint assessments that provide a robust data package enabling researchers to make critical decisions for their pipeline candidates.
Behavior
Pain behavior tests include dynamic weightbearing and Hargreaves to assess the distribution on each paw and sensitivity to heat.
Biomarkers
Evaluate pro-inflammatory and anti-inflammatory biomarkers from CSF samples.
Histology
IHC and histological staining to evaluate inflammatory markers in the paw skin.
Scientific Data
MD Biosciences utilizes common pain tests to assess the level of neuropathic pain as a result of chemotherapy treatment. Data shows Von Frey force (g) in the chemotherapy-induced peripheral neuropathy model.
