MediciNova, Inc. files its annual report describing a late‑stage biopharmaceutical pipeline built around two lead drug candidates, MN‑166 (ibudilast) and MN‑001 (tipelukast). The company focuses on serious diseases with high unmet need, including progressive multiple sclerosis, amyotrophic lateral sclerosis, glioblastoma, degenerative cervical myelopathy, ARDS in COVID‑19, and NASH/NAFLD with metabolic disorders.
MN‑166 has Fast Track designations in progressive MS and ALS and Orphan‑Drug designations in ALS and glioblastoma, supported by multiple Phase 2 and Phase 2b/3 trials and extensive preclinical data. MN‑001 targets fibrotic and metabolic liver disease, with Fast Track for NASH with fibrosis and positive Phase 2 and preclinical results in triglyceride reduction and anti‑fibrotic effects. The report notes continued operating losses, no approved commercial products, dependence on external manufacturing and strategic partners, and significant clinical, regulatory, and market competition risks.
MediciNova furnished preliminary, unaudited results for the year ended December 31, 2025 via its Tanshin report filed with the Tokyo Stock Exchange. Revenue was $0.41M, all from a Mayo Foundation ALS research agreement, versus no revenue in 2024.
The company recorded an operating loss of $13.28M and a net loss of $12.00M, slightly higher than 2024, as research and development held around $7.2M and general and administrative expenses rose to $6.16M including Standby Equity Purchase Agreement fees. Basic and diluted net loss per share was $0.24.
Cash and cash equivalents were $30.81M as of December 31, 2025, with operating cash outflow of $9.81M. MediciNova expects 2026 operating expenses of about $16.2M (an 18% increase) and believes current cash can fund operations at least through the end of February 2027, supported by existing ATM programs and a $30.0M standby equity facility.

MediciNova, Inc. (MNOV) files an S-1 describing its clinical-stage pipeline centered on MN-166 (ibudilast) and MN-001 (tipelukast) and a financing arrangement with YA. MN-166 showed positive Phase 2b SPRINT-MS results including a 48% reduction in whole brain atrophy versus placebo (p=0.04) and a 26% reduction in risk of confirmed disability progression (HR=0.74); results were published in the New England Journal of Medicine.

Medicinova, Inc. (MNOV) – Form 4 insider filing
On 17 June 2025, director Carolyn Beaver was granted an option to purchase 20,000 shares of Medicinova common stock. The option’s exercise price is $1.26 per share and it will expire on 16 June 2035.
The award vests in four equal installments of 5,000 shares on the following dates, contingent on continued board service:
- 30 Sep 2025
- 31 Dec 2025
- 31 Mar 2026
- 30 Jun 2026
Following this grant, Beaver reports beneficial ownership of 20,000 derivative securities and no change in non-derivative holdings was disclosed.
The transaction was coded “A” (grant) and filed as a single-reporting-person Form 4 on 20 June 2025. No 10b5-1 plan was indicated.
Investor takeaway: This appears to be a routine equity incentive award to align director interests with shareholders; the 20,000-share size is modest relative to Medicinova’s outstanding share count and therefore immaterial from a dilution standpoint.
