Specialized, Customized or Surgical CNS Pharmacology

 

Central Nervous System:

CBI offers a variety of customized, investigative, and specialized surgical CNS pharmacology and efficacy models. These studies maybe hypothesis-driven or requested by regulators, and may require specialized or unusual techniques or methods. If you have a specialized CNS study requirement, our skilled scientists can facilitate the protocol development as well as the conduct of these novel, difficult and specialized projects

CBI welcomes the opportunity to develop new customized studies and efficacy models. The following are some examples of specialized surgical efficacy and toxicology studies that we can successfully conducted. We will help you design your next unique custom surgical study! Some of our more esoteric capabilities include:

CNS Toxicology and Pharmacokinetics:

Toxicology studies involving the CNS are often complex and may include efficacy components, for example evaluating the toxicity of a test article in the presence of the disease indication, such as Parkinson’s Disease or muscular sclerosis. Routes of administration can be unusual-in addition to the standard IV, IM, oral routes, some CNS drugs require direct infusion into the spinal cord or brain. This makes the toxicology study much more complex than a simple toxicology dosing study.

  • GLP and NonGLP CNS toxicity and efficacy-toxicology studies with cellular therapies, stem cells, biologics, viruses, small molecules, devices, others

In addition to standard assessments, CNS behavioral tests, pcr, Elisas, immunohistochemistry

  • Pharmacokinetic and toxicokinetic assessments of CSF and CNS tissues
  • Blood and CNS tissues
  • CSF from lateral ventricles or cisterna magna
  • Peri-lymph from cochlea
  • Stereotaxic dosing or sample collection
  • Intraventicular dosing

 

Combination efficacy and toxicology studies centered on the CNS.

Examples include:

  • Anesthesia-induced cerebral toxicity in neonates – please review our publication
  • Intracerebral or intraspinal oncology, implantation of intracerebral tumors and treatments
  • Intrathecal, intracerebral, intracisternal and intraventicular dosing studies in small animals and dogs – please review our  publication
  • Meningeal, dural and skull trauma with repair and patching
  • Stereotaxic administration dosing studies-ex 6OHDA for Parkinson’s, or tumor treatment
  • CNS inflammation or demyelination
  • Stent and vascular device deployment
  • Combination stem cell and device toxicity and efficacy studies
  • Spinal cord and brain injury and contusion models

 

CNS Efficacy Studies

CBI offers a wide variety of CNS efficacy or pharmacology studies to assess test article efficacy or explore mechanisms of action in out bred or genetically modified animals.

  • OHDA or MPTP Induced Parkinson’s Disease

Anesthesia or ketamine-induced cerebral toxicity in neonates – please review our publication

  • Intracerebral or intraspinal oncology, implantation of intracerebral tumors and treatments
  • Intrathecal, intracerebral and intraventicular dosing studies in small animals and dogs – please review our  publication
  • Meningeal, dural and skull trauma including repair and patching

 

CNS inflammation or demyelination: Experimental Allergic Encephalitis, cuprizone-induced demyelination, myasthenia gravis, Alzheimer’s Disease
