Builds a clinical-stage pipeline around late-stage ALXN1840 for Wilson disease and MNPR-101 radiopharmaceutical programs for solid tumors. With no approved products or revenue in the latest opened filing, execution centers on regulatory work, clinical trials, radioisotope supply, and outside financing.
Develops clinical-stage medicines through licensing and internal work, with ALXN1840 as the dominant near-term program for Wilson disease. The MNPR-101 platform uses a humanized antibody targeting uPAR to carry imaging or therapeutic radioisotopes into solid-tumor programs.
Operations are based in Wilmette, Illinois, and the portfolio is tied mostly to U.S. regulatory and clinical execution. ALXN1840 came from an Alexion/AstraZeneca Rare Disease license, while MNPR-101 traces back to assets contributed at formation.
No approved products or revenue were reported in the latest opened annual filing. The business depends on FDA review of ALXN1840, early oncology trial execution, radioisotope supply, third-party manufacturing and trial providers, and continued financing.
