The purpose of the study in Part 1 (dose escalation) and in Part 2 (dose expansion) is to determine the recommended Phase 2 dose(s) (RP2D\[s\]) and evaluate preliminary clinical efficacy. Part 3 (dose expansion) will confirm safety and preliminary clinical activity at the RP2D. Part 4 (RP2D expansion; MoonRISe-2) will assess the overall complete response (CR) in participants with intermediate-risk-non-muscle invasive bladder cancer (IR-NMIBC; means the cancer cells are only in the bladder's inner lining).
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Johnson & Johnson (JNJ) is the sponsoring company for this trial. BiotechSign currently grades this company C (51/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
