Manages Jemperli and imsidolimab royalties through GSK and Vanda partnerships.

Collects partner royalties from GSK’s marketed oncology therapy Jemperli and Vanda-licensed imsidolimab, which is under FDA review for generalized pustular psoriasis. The virtual model has no internal drug pipeline after the First Tracks spin-off, and Jemperli supplies nearly all revenue while its royalties service the Sagard monetization obligation.
Manages royalty rights tied to two antibodies discovered in-house: Jemperli, GSK’s marketed oncology therapy, and imsidolimab, an antibody licensed globally to Vanda for generalized pustular psoriasis. Jemperli is sold in the United States, Europe and other markets, while imsidolimab remains under FDA review.
Operates a virtual, low-overhead model after spinning its clinical pipeline into First Tracks Biotherapeutics. Revenue comes from partner royalties rather than drug development or an internal commercial network; Vanda-related milestone rights transferred to First Tracks.
Depends primarily on GSK’s development, commercialization and indication-expansion decisions. Jemperli royalties currently service a non-recourse Sagard monetization obligation until contractual thresholds are met, while imsidolimab economics depend on regulatory approval and Vanda’s launch execution.

This quarter's institutional total failed a plausibility check; shown: the largest filers plus last quarter's remainder.
A stock split fell inside the quarter, so quarter-on-quarter changes are not shown.
These groups come from separate filings that can overlap, so they add to 116.60%; nothing is left for Other.
