IntelliGel is a proprietary novel supramolecular thermogel platform that is currently formulated in dermatological products sold in the US and China. Transparent, non-allergenic, and reversible, IntelliGel is based on poloxamers and other unique polymers that allow for formulations with relatively high water content. Behaving like water at room temperature, it forms a viscous gel when applied to warmer surfaces and can be used to deliver active substances to the front of the eye.

RP501 is currently being developed as a medical device in Europe. The safety and efficacy of RP501 was tested in the recent RP101 Phase II trial conducted by Redwood Pharma in post-menopausal women. RP501 (the vehicle control) improved both subjective symptoms and objective signs such as dryness, foreign body sensation, tear fluid production, tear break-up time and corneal staining.

Redwood Pharma will now conduct a clinical medical device study of RP501 to further test efficacy in both men and women over 18 years of age, safety and tolerability in those dry eye sufferers wearing contact lenses. With approval from the local ethics' commission in Austria, Redwood is now awaiting final clinical trial approval from the Austrian Federal Office for Safety in Health Care (BASG). Once granted, the new trial supporting a CE-marking approval will begin and last throughout the current year.

RP501 will address a large market where there is a need for better therapies that offer effective relief from dry eye with fewer administrations per day. RP501 has significant therapeutic and commercial potential as a next-generation first-line therapy to treat the majority of DED sufferers, including males and females of all ages. The global market was valued at US$2.3 billion in 2019 and expected to grow to US$2.9 billion by 2030 (Source: Transparency Market Research 2020). Today, DED sufferers turn first to artificial tears (saline eye drops) to provide temporary relief.
