Moleculin Biotech ( (MBRX) ) has provided an update.
On May 13, 2026, Moleculin Biotech reported that it is nearing the first unblinding of data from its pivotal Phase 2B/3 MIRACLE trial of Annamycin plus cytarabine in relapsed or refractory acute myeloid leukemia, with the initial 45-patient unblinding expected before June 30, 2026. The adaptive, global, randomized study compares two dosing arms of Annamycin plus cytarabine to cytarabine with placebo, and is enrolling second-line AML patients, including those previously treated with Venetoclax.
The company said blinded efficacy data from the first 45 subjects show a composite complete remission rate above 40% and a complete remission rate near 30%, markedly higher than the roughly 17–18% historical complete remission rates seen with cytarabine alone in similar populations. With 56 of the planned 90 Part A subjects already recruited as of May 1 and no cardiotoxicity reported so far, Moleculin is signaling that Annamycin could represent a significant advance over standard cytarabine regimens for this high-unmet-need AML group and help support its push toward potential regulatory approval.
The most recent analyst rating on (MBRX) stock is a Buy with a $22.00 price target. To see the full list of analyst forecasts on Moleculin Biotech stock, see the MBRX Stock Forecast page.
Spark’s Take on MBRX Stock
According to Spark, TipRanks’ AI Analyst, MBRX is a Neutral.
The score is held back primarily by weak financial performance (no revenue, sustained losses, and continued cash burn with financing dependence). Offsetting factors include multiple positive corporate developments around Annamycin (trial progress/safety and strengthened patent coverage), while technicals are broadly neutral and valuation signals are hard to rely on given the pre-revenue profile.
