IRAK4 plays a key role in innate immune responses and is critical for signaling through Toll-like and IL-1 family cytokine receptors. TrkA is the receptor for nerve growth factor, a neurotropic factor essential for the development and survival of neurons. It causes heightened sensitivity through upregulation of TRPV1 and induces angiogenesis and vasodilation. The unique dual action of our IRAK4/TrkA small molecule inhibitor provides a novel approach for the treatment of a variety of inflammatory diseases, including atopic dermatitis, asthma, Behçet's disease, conjunctivitis, and papulopustular rosacea.

RORγt is the key transcription factor induced by IL-23 signaling, resulting in Th17 cell polarization and downstream production of IL-17 (and other Th17 associated cytokines). Both anti-IL-17 and anti-IL-23 biologics have demonstrated a profound effect in treating psoriasis; targeting RORγt might provide similar utility, but with a small molecule approach. Additional indications include chronic graft-versus-host disease, lichen planus, rosacea, and inflammatory bowel disease.

MRGPRX2 is a member of the MAS-related G-protein coupled receptor (MRGPR) family and has evolved to be an important target for neuroinflammation and itch. MRPGRX2 is expressed on both sensory neurons and mast cells, and responds to a variety of itch-causing agents. Neurons and mast cells are in close proximity in the skin and directly interact with each other. Inhibiting MRGPRX2 signaling should reduce this neuro-inflammatory response and blocks itch-transmission at its source, thus providing immediate itch relief. Other itch treatments focus on targets in the brain and have proven to be slower acting and not without side effects. This novel investigational therapy has the potential to address itch associated with many underlying medical conditions.

PKCϴ, a member of the protein kinase C (PKC) family of kinases, is primarily expressed in T-cells and has a dual role in T-cell biology. First, activation of PKCϴ leads to effector T-cell activation, proliferation, and production of IL-2. Second, inhibition of PKCϴ (genetic knockouts or pharmacological inhibition) leads to an increase in both the numbers and functionality of regulatory T-cells. Mice lacking functional PKCϴ are highly resistant to inflammatory diseases. Genetic variants within the gene for PKCϴ have been associated with many inflammatory diseases. Potential indications include rheumatoid arthritis, asthma, psoriasis, atopic dermatitis, and Crohn’s disease.

Emma Guttman-Yassky, MD, PhD, is the vice chair for research and the incoming chair of the Kimberly and Eric J. Waldman Department of Dermatology at the Icahn School of Medicine at Mount Sinai in New York City. She is a world-renowned dermatologist and physician scientist whose study of molecular and cellular pathomechanisms of inflammatory skin diseases, particularly eczema/atopic dermatitis (AD), and recently alopecia areata in humans, is opening doors to new therapeutic discoveries and treatments for millions of patients around the globe. Dr. Guttman-Yassky also serves as director of the Center for Excellence in Eczema and director of the laboratory of inflammatory skin diseases at the Icahn School of Medicine at Mount Sinai.

Dr. Guttman-Yassky has developed comprehensive molecular maps of AD, defining skin differentiation and immune circuits characterizing this disease and biomarkers of disease and treatment response in skin biopsies. And recently she has been using a minimally invasive approach to sample the skin. She has also extended her research interest to alopecia areata and other inflammatory skin diseases, where she is also translating her findings to possible novel therapeutic targets and treatments.

Dr. Guttman has 2 board certifications in dermatology, after completing dermatology training in both Israel and the US.

James G, Krueger, MD, PhD, is head of the laboratory for investigative dermatology at the Rockefeller University. He also serves as a physician, codirector of the Center for Clinical and Translational Science at the Rockefeller University Hospital, and Chief Executive Officer of the Rockefeller University Hospital in New York City.

Dr. Krueger earned his bachelor’s degree from Princeton University and a PhD in virology and cell biology from the Rockefeller University. He received an MD from Cornell University Medical College, where he also completed an internship in internal medicine and residency in dermatology. Dr. Krueger is certified by the American Board of Dermatology.

Dr. Krueger’s research group at Rockefeller was the first to conduct clinical trials with specific, targeted immune antagonists in psoriasis, and this work established that elimination of pathogenic T cells from skin lesions could reverse the full pathological phenotype of psoriasis. This work changed the disease model for psoriasis from that of a keratinocyte-driven disease to one of T-cell–mediated pathology. Since then, his group has used immune-based therapeutics to dissect inflammatory pathways in psoriasis and to conduct parallel biomarker studies that define mechanisms of targeted therapeutics in human populations. His group discovered elevated expression of IL-23 in psoriasis lesions and the contribution of this cytokine to an inflammatory axis dominated by Th17 T-cells was first reported by his group. This work has also provided the “disease maps” for cytokine-driven inflammation in psoriasis, which has been the basis for biologic therapeutic development in psoriasis. The successful development of antagonists to IL-12/23, IL-23/IL-39, and IL-17 (at least 10 different drugs) extends from this research and early clinical trials conducted by his group.

In a larger way, the approach taken in psoriasis has greatly altered a traditional pathway of scientific discovery that is based on establishing a disease model in animals or cell culture. The model of bedside-to-bench translational science in psoriasis has now been successfully extended to other inflammatory diseases, such as atopic dermatitis, alopecia areata, and others, that are extremely active with translational studies in humans and are highly dependent on cytokine-related disease maps from clinical samples of their respective diseases. His group is now actively working on creating disease maps, biomarkers, and new therapeutics for hidradenitis suppurativa.

Dr. Krueger has more than 400 scientific publications, most in high-impact journals. And he has been honored for his scientific and clinical contributions by election to the Association of American Physicians.
