aine patches experience insufficient pain relief. Lidocaine patches are difficult to use, fall off, and look unsightly with possible skin sensitivity and irritation. Additionally, lidocaine patches can only be used for 12 hours and then need to be removed for 12 hours before being reapplied. Prescription lidocaine patches are only approved for PHN, and the market is currently made up of both branded and generic offerings.

   Market Potential

   It is estimated that PHN affects approximately 120,000 patients per year in the United States. According to a third-party report, the total addressable market for GTx-101 could be as large as $2.5 billion, consisting of approximately $200 million for PHN pain and $2.3 billion for non-PHN pain indications.

   Clinical Data

   To date, we have conducted four Phase I trials in healthy volunteers to assess the PK, safety, and tolerability of GTx-101 and to determine the plasma levels of bupivacaine hydrogen chloride administered as a single dose in various concentrations between 30 mg (three sprays) and 2100 mg (twenty sprays).

   These trials demonstrated that GTx-101 is well absorbed through the skin, as indicated in the graph below, while very little is absorbed systemically.

   In all four trials, the administration of GTx-101 to healthy volunteers was safe and well tolerated. In addition, no evidence of skin irritation was observed at the application site following the spray administrations. The data below is from two separate trials superimposed on each other – one trial of GTx-101 and one trial of the Lidoderm patch.

   Regulatory

   The data from the single dose Phase 1 clinical trial for GTx-101 was submitted to the FDA’s Division of Anesthesiology and feedback was received at a pre-IND meeting that informed the design of pre-clinical toxicology studies and a clinical and regulatory pathway to approval under section 505(b)(2). We completed a minipig skin sensitivity study in the second calendar quarter of 2022, and we initiated a single dose PK trial in healthy human volunteers in July 2022. Topline results from this single dose PK trial were reported in December 2022, and the results met all primary outcome measures.

   Next Steps

The
further development of GTx-101 has been deprioritized in favor of our focus on
development of GTx-104. Pending additional funding
