Coming October 29: SITC releases its late-breaking abstract titles. We’ll add their presenting authors’ institutions to this guide once they’re out.

Melanoma Institute Australia at SITC 2026

Nov 4–8, 2026 Phoenix, AZ ~6k attendees Website

Melanoma Institute Australia brings 2 presentations to SITC 2026 in Phoenix. Its program centres on melanoma treated before surgery and on new mRNA medicines. One study maps lymphoid structure-like niches over time in melanoma treated with ipilimumab and nivolumab, and another reports lasting responses to a self-replicating mRNA that makes IL-12, given alone in advanced solid tumors.
