Improved Oral Delivery of Cyclobenzaprine – Feasibility Proposal
Background
Lipocine Inc. (Lipocine) has proprietary technology, Lip’ral™, for improved oral absorption of poorly water soluble drugs and elimination of food effects on absorption. The technology has been validated in clinical and preclinical studies with several different poorly water soluble drugs, and is protected by issued and pending patents.
Tonix Pharmaceuticals, Inc. (formerly known as Krele Pharmaceuticals, Inc., Tonix) has contracted Lipocine to conduct a feasibility evaluation for the improved oral delivery of Cyclobenzaprine, a muscle relaxant. Cyclobenzaprine is currently sold under the brand name Flexeril® and there are several generics. It is available as 5 mg, 7.5 mg and 10 mg tablets.
The specific objectives of the feasibility evaluation are:
| 1. | Develop Lip’ral™ formulations of Cyclobenzaprine at slightly lower strength than the marketed product; select two formulations for a Phase I study. |
| 2. | Manufacture, test and release the lots under GMP. Conduct a Phase I clinical study under a US IND to determine whether the Lipocine formulations are bioequivalent to Flexeril® 5 mg tablet or have faster absorption, faster elimination or the same or lower area under the curve (AUC) than cyclobenzaprine 5 mg. |
The feasibility program involves pre-formulation, formulation development and stability evaluation with the goal of selecting two formulations for a Phase I study. It also includes manufacture, testing and release of clinical lots of the selected formulation and conducting a Phase I study to determine the pharmacokinetics of the Lipocine formulations relative to Flexeril®.
The tasks, timelines and cost of the feasibility program are presented in detail below.
