Recent Updates on CABA stock

Over the last 24 hours, Cabaletta Bio shares traded against a backdrop of significant strategic and regulatory updates for its lead CAR T therapy, rese-cel, and an analyst price target reduction. The company laid out 2026 priorities focused on moving rese-cel toward registration in multiple autoimmune diseases, including an FDA‑aligned 17‑patient registrational cohort in dermatomyositis and antisynthetase syndrome that could support its first BLA in myositis next year, plus newly aligned single‑arm registrational cohort designs in systemic lupus erythematosus and lupus nephritis and an RMAT designation in systemic sclerosis, with further registrational pathways for scleroderma and myasthenia gravis expected in 2026. Operationally, Cabaletta received clearance to use Cellares’ fully automated Cell Shuttle platform for rese-cel manufacturing, which is intended to validate GMP readiness, reduce costs, and enable scalable global supply if approved, while clinically it is testing higher doses and no‑preconditioning regimens in pemphigus vulgaris and lupus, with multiple Phase 1/2 readouts across lupus, systemic sclerosis and myasthenia gravis expected in the first half of 2026. Despite this broad pipeline momentum, Morgan Stanley lowered its price target on CABA, with the change driven not by a negative view on the asset but by the firm’s broader sector outlook: it expects continued outperformance in U.S. small‑ and mid‑cap biotech as select names transition from high capital consumption to cash generation, while large‑cap biopharma faces a patent cliff, and it is repositioning expectations and valuation assumptions within this shifting landscape. Meanwhile, TipRanks’ AI analyst ‘Spark’ characterizes CABA as constrained by weak current financials (no revenue, widening losses, and meaningful cash burn) and mixed technicals, even as recent positive clinical and program updates partially offset these concerns, contributing to a neutral overall stance on the stock in the near term.

Spark’s Take on CABA Stock

According to Spark, TipRanks’ AI Analyst, CABA is a Neutral.

The score is primarily constrained by weak financial performance (no revenue, widening losses, and heavy cash burn implying funding risk). Technicals are also soft with negative MACD and price below key short/intermediate moving averages. Positive corporate events (encouraging clinical progress and manufacturing advances) provide some offset, but not enough to overcome the current financial and momentum headwinds.
