# Monopar Wins FDA Rare Pediatric Disease Designation

Monopar Therapeutics Inc ( (MNPR) ) has provided an update.

On June 30, 2026, Monopar Therapeutics announced that the U.S. Food and Drug Administration granted Rare Pediatric Disease designation to its late-stage Wilson disease candidate ALXN1840 (tiomolibdate choline). The designation, aimed at serious conditions primarily affecting children, recognizes the burden of Wilson disease and positions ALXN1840 as a potentially important new option for this rare genetic copper disorder.

Existing clinical data show ALXN1840 met the primary endpoint in a Phase 3 pivotal trial, delivering rapid, sustained copper mobilization beyond standard of care over 48 weeks and demonstrating durable clinical benefit with a favorable safety profile across 645 patient-years in 266 patients. The regulatory milestone strengthens Monopar’s profile in rare disease drug development and could enhance the value of its Wilson disease franchise as it advances toward possible U.S. approval.

The most recent analyst rating on (MNPR) stock is a Buy  
with a $117.00 price target.

**Spark’s Take on MNPR Stock**

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

The score is held back primarily by weak financial performance (no revenue, widening losses, and rising cash burn) and loss-driven valuation. Offsetting these are strong technical momentum and a meaningful set of positive clinical-data corporate events that improve the near-term narrative, though funding and execution risk remain central.
