Potnak - In fairness, responsibility for the speculation regarding potential values has been fuelled at least in part by Sareum - http://www.sareum.com/files/2215/3838/2124/Sareum_2018_FY_Results_.pdf
TD-1473 (a pan-JAK inhibitor) – licensed by Janssen from Theravance (2018) at the end of Phase 1 studies for $100M cash up-front, up to $900M in milestone payments, plus royalties*
? Filgotinib (JAK1 inhibitor) – licensed by Gilead from Galapagos (2015) at the end of Phase 2 trials for $300M cash and $425M equity investment up-front, up to $1,350M in milestone payments, plus 20%+ royalties*
? Undisclosed TYK2 inhibitor (plus other assets) – Celgene formed an alliance with Nimbus Therapeutics (2017) in preclinical stage for undisclosed up-front and milestone payments
Approved products targeting the JAK family with blockbuster sales potential, despite warnings based on side effects related to JAK2/JAK3 activity, include:
? Xeljanz® tofacitinib (Pfizer) (JAK1/JAK3 inhibitor) - approved for rheumatoid and psoriatic arthritis and ulcerative colitis, with 2017 sales of $1.35Bn*, despite black box warnings for serious infections and lymphoma
? Olumiant® baricitinib (Eli Lilly) (JAK1/JAK2 inhibitor) – approved from rheumatoid arthritis, with expected peak sales of approximately $1Bn*, but with black box warnings for serious infections, lymphoma and thrombosis
? Jakafi® ruxolitinib (Incyte/Novartis) – approved for myelofibrosis and polycythemia vera (a type of blood cancer) with 2017 sales of $1.1Bn* despite warnings of infections and blood cell counts
The scale of the deals and sales delivered/forecast for these candidates and products targeting TYK2 and related JAK family members gives Sareum confidence in the exciting, high value market opportunity for SDC-1801
