Lawsuit Filed Against Cabaletta Bio

Allegations Against CABA

Cabaletta Bio’s lead product candidate is DSG3-CAART.  This is presently in Phase I clinical trial for the treatment of mucosal pemphigus vulgaris, an autoimmune blistering skin disease, and Hemophilia A with Factor VIII alloantibodies.  Pursuant to its IPO conducted on or about October 24, 2019, Cabaletta Bio sold approximately 6.8 million shares of common stock priced at $11.00 per share, for approximate proceeds of $69.5 million. 

On December 14, 2021, Cabaletta Bio issued a press release “report[ing] top-line data on biologic activity from the two lowest dose cohorts in the DesCAARTes™ Phase 1 clinical trial of DSG3-CAART for the treatment of patients with mucosal Pemphigus Vulgaris (mPV).”  Among other results, Cabaletta Bio reported that two cohort participants had “disease activity scores . . . that worsened . . . after DSG3-CAART infusion” and thus “reduced or discontinued selected systemic therapies prior to DSG3-CAART infusion, as required by the protocol”, while another participant “subsequently received systemic medication to improve disease activity after DSG3-CAART infusion.”  On this news, Cabaletta Bio’s stock price fell by more than 73%, damaging investors.

Misleading Statements Alleged

The complaint against Cabaletta Bio alleges that defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that:

  1. Top-line data of the Phase 1 Clinical Trial indicated that DSG3-CAART had, among other things, worsened certain participants’ disease activity scores and necessitated additional systemic medication to improve disease activity after DSG3-CAART infusion;
  2. accordingly, DSG3-CAART was not as effective as the Company had represented to investors;
  3. therefore, the Company had overstated DSG3-CAART’s clinical and/or commercial prospects; and
  4. as a result, the Company’s public statements were materially false and misleading at all relevant times.
