Detailed Business Update and Potential Price Sensitive Developments

Clinical Pipeline Progress

Cartesian Therapeutics continues to advance its flagship asset, Descartes-08, across multiple high-value autoimmune disease indications. The Phase 3 AURORA trial is particularly noteworthy: this randomized, double-blind, placebo-controlled study will evaluate Descartes-08 versus placebo in approximately 100 patients with acetylcholine receptor antibody positive, generalized myasthenia gravis. The trial uses a novel six once-weekly outpatient infusion regimen without preconditioning chemotherapy, aiming to measure the proportion of patients achieving a clinically meaningful improvement in MG Activities of Daily Living (MG-ADL) score at month four.

The company also initiated the Phase 2 TRITON study in moderate-to-severe, multi-refractory dermatomyositis and antisynthetase syndrome, both high unmet-need populations. The trial will assess safety and efficacy of Descartes-08, with an initial look at the first 10 patients to inform the path toward a pivotal trial.

In pediatrics, the Phase 1/2 HELIOS trial is underway, targeting rare and severe juvenile dermatomyositis. This trial further leverages the FDA’s Rare Pediatric Disease Designation, which can potentially accelerate regulatory pathways and market exclusivity.

Financial and Operational Highlights

A critical update for shareholders is the company’s financial runway. With \$120.4 million in cash (including equivalents and restricted cash) as of March 31, 2026, Cartesian expects to fund planned operations through mid-2027. This guidance includes all ongoing pivotal and key clinical trials. The company strengthened its balance sheet in Q1 with a \$14.6 million raise from its ATM program.

R&D expenses rose to \$19.5 million owing to the acceleration of the AURORA trial, but this was offset by cost savings from the strategic discontinuation of lupus development. General and administrative expenses declined, reflecting improved operational efficiency.

However, the net loss increased sharply to \$39.2 million, which may raise concerns among investors regarding capital requirements, dilution risk, and the need for future fundraising. The company’s stockholders’ deficit also widened to \$148.1 million.

Regulatory Strategy and Differentiation

Descartes-08 stands out from traditional CAR-T products with its outpatient, chemotherapy-free administration, lowering barriers to adoption and reducing risk of adverse events such as genomic integration and cancer transformation. Multiple FDA designations further enhance the product’s regulatory profile and market prospects.

Importantly, the company has refocused its pipeline, discontinuing lupus development to concentrate capital and resources on MG, myositis, and pediatric JDM—signaling a disciplined approach to portfolio management.

Risks and Forward-Looking Considerations

Investors should be aware of several potential risks and uncertainties:

• Success in ongoing trials is not guaranteed; early results may not predict pivotal outcomes.
• Company faces recurring losses, dilutive capital raises may be necessary if development timelines extend or trials require expansion.
• Regulatory, operational, or geopolitical delays could impact data readouts and commercialization timelines.
• Any failure to meet trial endpoints, secure funding, or maintain key partnerships could materially impact the company’s share price.

Conclusion: Key Takeaways for Investors

• Pivotal Phase 3 data in MG, initial Phase 2 readouts in myositis, and early pediatric data represent significant upcoming potential catalysts.
• The company’s strong cash position is supportive in the near term but will be watched closely due to a widening loss and negative equity.
• Strategic pipeline focus and differentiated product profile may attract further investor interest as data matures.
• Any clinical, regulatory, or financial setbacks could be share price moving events—investors should monitor trial enrollment, data readouts, and funding updates closely.
