FDA Places Partial Clinical Hold on MacroGenics Trial

An update from MacroGenics ( (MGNX) ) is now available.

On February 23, 2026, MacroGenics announced that the U.S. Food and Drug Administration placed a partial clinical hold on its Phase 2 LINNET trial of lorigerlimab, a bispecific DART molecule targeting PD-1 and CTLA-4, in patients with gynecologic cancers. Under the hold, enrollment of new participants is paused, though the 41 patients already dosed in the platinum-resistant ovarian and clear cell gynecologic cancer cohorts may continue receiving treatment.

The FDA action followed MacroGenics’ own temporary enrollment pause after serious safety events across four patients, including Grade 4 thrombocytopenia, myocarditis, neutropenia with septic shock, and one resulting Grade 5 event. The move highlights heightened regulatory scrutiny around lorigerlimab’s safety profile and injects uncertainty into the development timeline of a key oncology asset for MacroGenics and its stakeholders.

The most recent analyst rating on (MGNX) stock is a Hold with a $2.00 price target. To see the full list of analyst forecasts on MacroGenics stock, see the MGNX Stock Forecast page.

Spark’s Take on MGNX Stock

According to Spark, TipRanks’ AI Analyst, MGNX is a Neutral.

The score is primarily held down by weak financial performance (declining revenue, large ongoing losses, and significant cash burn that increases financing risk). Technicals provide some offset with recent positive momentum and price strength versus moving averages, but signals are nearing overbought. Valuation remains unattractive due to negative earnings, and a negative corporate event (CMO departure) adds execution risk.
