This investigation focuses on whether NGM issued misleading and/or false statements and/or failed to disclose information pertinent to investors. On May 24, 2021, NGM announced that it would be abandoning its liver disease treatment candidate after it failed to demonstrate efficacy in its Phase 2 study. According to NGM, “The 24-week Phase 2b ALPINE 2/3 was an equally randomized, double-blind, placebo-controlled study that assessed the efficacy, safety and tolerability of 0.3 mg, 1 mg and 3 mg doses of aldafermin once-daily subcutaneous injections compared to placebo. The study did not meet its primary endpoint evaluating a dose response showing improvement in liver fibrosis by >1 stage with no worsening of NASH at week 24 (p=0.55), analyzed using a dose response-driven statistical analysis plan (Multiple Comparison Procedure Modeling, or MCP-Mod). The study did achieve statistical significance versus placebo on certain secondary endpoints, including NASH resolution (at the 3 mg dose) and multiple non-invasive measures of NASH, including liver fat content reduction by MRI-PDFF, ALT, AST and Pro-C3 (at the 1 mg and 3 mg doses).” Shares of NGM fell almost 40% in intraday trading based on this news.
