SOUTH SAN FRANCISCO, Calif. - Kezar Life Sciences , Inc. (NASDAQ:KZR) has announced significant updates regarding its clinical trials, notably the continuation of its PORTOLA trial and the termination of its PALIZADE trial. The Independent Data Monitoring Committee (IDMC) has recommended the PORTOLA Phase 2a clinical trial for zetomipzomib in patients with autoimmune hepatitis (AIH) proceed without modification. The IDMC's decision came after reviewing safety data from participants, including those who have moved on to the open-label extension phase. The trial, which has completed patient enrollment, is on track to report topline data in the first half of 2025.
Conversely, the PALIZADE Phase 2b clinical trial for zetomipzomib in patients with active lupus nephritis (LN) will be discontinued. The decision follows an IDMC recommendation after the occurrence of four Grade 5 serious adverse events (SAEs), including fatalities, among participants in the Philippines and Argentina. Kezar will conduct a comprehensive review of the safety events from the PALIZADE trial, which had enrolled 84 patients before termination.
Kezar's CEO, Chris Kirk, PhD, expressed confidence in the potential of zetomipzomib as a treatment for AIH, while acknowledging the disappointment in discontinuing the LN program. The strategic shift allows Kezar to extend its financial runway and concentrate efforts on addressing the significant unmet medical need in AIH, a rare disease with severe consequences if left untreated.
The company's unaudited cash position stands at approximately $148 million as of September 30, 2024. Kezar is a clinical-stage biopharmaceutical entity focused on developing small molecule therapeutics for immune-mediated diseases.
The PORTOLA trial is a randomized, double-blind study assessing zetomipzomib's efficacy and safety in AIH patients who are not adequately responding to standard care. The primary efficacy endpoint is the proportion of patients achieving a complete biochemical response at Week 24.
AIH is a rare chronic condition where the immune system attacks the liver, potentially leading to cirrhosis, liver failure, and cancer if untreated. The disease predominantly affects women and requires lifelong maintenance therapy, often involving corticosteroids with significant side effects. There is a pressing need for treatments that can reduce or eliminate the need for such immunosuppression.

Kezar Life Sciences' recent clinical trial developments have significant implications for the company's financial outlook and market position. According to InvestingPro data, Kezar's market capitalization stands at $65.28 million, reflecting the market's current valuation of the company in light of these developments.
The decision to focus on the PORTOLA trial for autoimmune hepatitis (AIH) aligns with InvestingPro Tips suggesting that Kezar "holds more cash than debt on its balance sheet" and "liquid assets exceed short term obligations." This financial stability is crucial as the company navigates the challenges of drug development and the recent setback with the PALIZADE trial.
However, investors should note that Kezar is "quickly burning through cash" and is "not profitable over the last twelve months," as highlighted by InvestingPro Tips. The company's revenue for the last twelve months as of Q2 2024 was $7 million, with a concerning gross profit margin of -1040.71%. These figures underscore the importance of the PORTOLA trial's success for Kezar's future prospects.
Despite these challenges, Kezar has shown "strong returns over the last month" and "over the last three months," with price total returns of 55.6% and 31.75% respectively. This recent market performance may reflect investor optimism about the potential of zetomipzomib in AIH treatment.
