CC chemokine receptor 6 (CCR6) is a G-protein coupled receptor involved in guiding immune cells through the body and the hallmark receptor for T helper 17 (Th17) cells, and is also expressed in other immune cell populations, such as B cells and innate lymphoid cells, among others.

With a promising IL-36 inhibitor for atopic dermatitis (AD, or eczema) at the phase II stage, Turn Therapeutics Inc. has gained $75 million in post-public commitments and meanwhile is pursuing a grassroots strategy to keep the coffers in balance.

The sparsity of mid-to-late stage prospects in atopic dermatitis (AD, or eczema) – which has proved an especially challenging indication – plus some newsmaking fizzles in the space have caused developers to probe new targets with particular intensity. Most popular approaches thus far involve IL-4, IL-13, thymic stromal lymphopoietin and JAK. Developers have stumbled for varying reasons such as high placebo response rates, safety or lack of clinical proof of concept. Among the potential AD rescuers is Nektar Therapeutics Inc. with rezpegaldesleukin (rezpeg), which takes aim at IL-2.
