 but with systemic exposure of the drug remaining well below established safety thresholds. SP-103 has three times the drug load of ZTlido (108 mg versus 36 mg) in the adhesive system and can potentially deliver three times the level of the drug within a targeted area, with the convenience of a single topical system. This level of dosage for SP-103 is comparable to the maximum approved daily dosage of ZTlido, or three topical systems for up to 12 hours during a 24-hour period. By contrast, delivering higher levels of drug with other lidocaine patches is encumbered by the underlying hydrogel technology that constrains the level of drug that can be loaded into the adhesive of those products. The level of drug product in such patches can be increased only with a thicker adhesive layer, which can result in a loss of adhesion performance and flexibility. Further, increasing product dimensions can allow delivery of the drug over a larger area, but does not increase drug delivery to a localized area under the topical system.

We believe the acute pain market presents an attractive commercial opportunity due to the large patient population, lack of any approved drugs and high level of unmet medical need. We believe developing and commercializing a topical non-opioid product targeting this segment of the pain population represents a commercially attractive strategy.

Neuropathic Pain Market Overview

Neuropathic pain is triggered as a consequence of a disease or lesion to the somatosensory nervous system, altering its structure and function. It is maladaptive, meaning that the pain can be felt in the absence of a stimulus, and responses to innocuous and noxious stimuli are pathologically amplified. Neuropathic pain affects around 7-10% of the general population.

Common causes of the condition include postsurgical and post-traumatic nerve damage or nerve pressure, vascular malformations, alcoholism, metabolic diseases such as diabetes, cancer, viral infections, and neurological diseases such as multiple sclerosis. Chronic neuropathic pain may also be associated with an underlying condition such as diabetic neuropathy or cancer, and with treatments such as chemotherapy.

Neuropathic pain often manifests as a burning sensation, with the affected regions becoming sensitive to even a slight touch. The symptoms of neuropathic pain include burning and sensations of electric shock, sleep disturbance, depression and anxiety, numbness, pins and needles, and difficulty in sensing temperatures.
