This clinical research trial will evaluate the safety and tolerability of an experimental drug, ALN-F1202, in healthy participants. The purpose of this trial is to learn about how safe and tolerable the experimental drug is. The trial is looking at several other research questions, including: * What side effects may happen from taking the experimental drug? * How much experimental drug is in the blood at different times? * Whether the body makes antibodies against the experimental drug (which could make the drug less effective or could lead to side effects). * What is the best dose of the experimental drug?
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.
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.
Regeneron Pharmaceuticals (REGN) is the sponsoring company for this trial. BiotechSign currently grades this company D (47/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
