MacroGenics (MGNX) Stock Crashes After Reporting Patient Deaths in TAMARACK Study – Hagens Berman

Key Takeaway: MacroGenics, Inc. has faced significant backlash after reporting five patient deaths in its Phase 2 TAMARACK study of MGC018, an antibody-drug conjugate for metastatic castration-resistant prostate cancer. Although the company initially reported promising interim safety data, the revelation of patient deaths led to a drastic 77% drop in stock prices and multiple analyst downgrades. Hagens Berman is investigating potential misleading statements regarding the safety data, as the recent findings contradicted earlier reports.

MacroGenics, Inc. (MGNX) Investigation:
The investigation currently focuses on the propriety of MacroGenics’ statements about certain data from its Phase 2 TAMARACK study for its antibody-drug conjugate MGC018 (“vobra duo”) in patients with metastatic castration-resistant prostate cancer (“mCRPC”).
On Apr. 3, 2024, MacroGenics announced Phase 2 TAMARACK interim safety data as contained in its abstract submitted to the American Society of Clinical Oncology on Feb. 6, 2024. The company said “[p]reliminary safety data from TAMARACK suggest that reducing the dose and frequency of vobra duo improves its safety and tolerability in men with mCRPC.” This news drove the price of MacroGenics shares up $4.11 (or up about 30%) on Apr. 4, 2024.
However, the optimism was short-lived. On May 10, 2024, MacroGenics revealed that 5 patients in the study died. This news drove the price of the company’s shares crashing $11.36 (or down about 77%) on May 10, 2024 and resulted in a slew of analyst downgrades.
In addition, SeekingAlpha reported that “Stifel was quick to downgrade MacroGenics (MGNX) after the TAMARACK readout, which, according to the firm, raised concerns over the drug’s safety and tolerability and appeared vastly different from previously disclosed abstract results.”
“We’re investigating whether MacroGenics may have misled investors about its Phase 2 TAMARACK interim safety data,” said Reed Kathrein, the Hagens Berman partner leading the investigation.
