Apr 2025Series BForbion Capital Partners (lead); Venrock Healthcare Capital Partners (lead); RTW Investments; Nextech Invest; +ND Capital; ARCH Venture Partners$155M$331MAIRNA, a biotechnology company based in Cambridge, MA, and Tübingen, Germany, develops RNA editing therapeutics using its proprietary RESTORE+™ platform to address rare and common diseases, including alpha-1 antitrypsin deficiency (AATD), cardiometabolic conditions, and others. The platform enables precise RNA edits to introduce beneficial genetic variants or repair mutations, offering re-administrable medicines with streamlined manufacturing. AIRNA's lead candidate, AIR-001, targets AATD, a genetic disorder causing lung and liver disease due to deficient AAT protein production. On April 1, 2025, AIRNA closed an oversubscribed $155 million Series B financing round, bringing total funding to approximately $245 million following prior Series A rounds totaling around $90 million. The round was co-led by Venrock Healthcare Capital Partners and Forbion Growth (also referred to as Forbion Capital Partners), with participation from RTW Investments, Nextech Invest, new and existing investors including ARCH Venture Partners, Forbion Ventures, and ND Capital. One source lists a Series B post-money valuation of $330.71 million. Proceeds will fund a Phase 1/2 clinical trial for AIR-001, with a clinical trial application expected in the second half of 2025, and expand the pipeline. AIRNA emerged from stealth in 2023 and this Series B follows quickly after its Series A2, reflecting strong investor confidence in RNA editing's potential amid competition, such as Wave Life Sciences' Phase 1 data for a similar AATD program. CEO Kris Elverum highlighted the approach's ability to mimic healthy genetic variants via single RNA edits, positioning it as a new class of genetic medicines distinct from one-time therapies.

Josh Brumm, General Partner at Forbion, joined AIRNA's Board of Directors, with Tim Lohoff as Board Observer. AIRNA's CEO Kris Elverum emphasized the cost benefits of RNA editing for large diseases and earlier treatment. The company differentiates with a platform enabling precise, durable edits for inaccessible targets. Post-Series A, AIRNA raised a $155 million oversubscribed Series B in April 2025, co-led by Venrock Healthcare Capital Partners and Forbion Growth, with RTW Investments, Nextech Invest, ARCH Venture Partners, Forbion Ventures, ND Capital, and others. Series B funds Phase 1/2 trials for AIR-001 (AATD candidate), with a clinical trial application planned for 2H 2025, and further pipeline development in cardiometabolic diseases.
