NEUROLOGICAL DOSING ROUTES
 (mice, rats, rabbits, NHPs)

CSF COLLECTION

INTRATHECAL PORTS FOR DRUG ADMINISTRATION
AND/OR CEREBROSPINAL FLUID (CSF) COLLECTION
IN NON-HUMAN PRIMATES (NHP)

OVERVIEW

Intrathecal administration (IT) is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF). Traditionally, the IT route of administration has been used to bypass the blood brain barrier (BBB).

Drugs may be administered by standard routes (IV, Oral) with CSF collection to assess CNS drug exposure and biomarker levels.

NHP MODEL

The anatomy and physiology of CNS models are comparable to a human.

CATHETERIZATION OF THE SPINAL IT SPACE

CSF catheters are implanted surgically via lumbar hemilaminectomy with catheter tip targeted for level of the cisterna magna. Access port is located on the back for ease of use.

INTRATHECAL (IT) INFUSION OF THERAPEUTIC AGENTS (TA)

IT lumbar dosing is utilized when:

BIOMERE EXPERTISE

In addition to chronic porting, our expertise includes experience with direct stick to the lumbar and cisternal intrathecal space for a variety of both IT dosing and CSF collection study.
