ADU-S100 (MIW815)

ADU-S100 was the first STING agonist in the clinic. Injected directly into tumours, it produced almost no responses, alone or with checkpoint blockade.

A cyclic dinucleotide STING agonist from Aduro (partnered with Novartis). Phase 1 monotherapy and combinations with spartalizumab or ipilimumab produced single-digit response rates; Novartis returned rights in 2019 and Aduro discontinued the programme in 2020. Merck's MK-1454 followed the same path. The pathway remains important (it mediates immune effects of radiation and ADCs), and systemic and antibody-conjugated STING agonists continue.

Lesson: intratumoural delivery to one lesion rarely produces systemic immunity in humans as it does in mice; pharmacology (rapid clearance, dosing) matters as much as the target.
