SOUTH SAN FRANCISCO, Calif. - Kezar Life Sciences , Inc. (NASDAQ:KZR), a biotechnology firm focused on developing treatments for immune-mediated diseases, has had its Investigational New Drug (IND) application for zetomipzomib, aimed at treating lupus nephritis (LN), put on clinical hold by the U.S. Food and Drug Administration (FDA). The FDA's decision came after Kezar voluntarily suspended enrollment and dosing in its Phase 2b PALIZADE clinical trial due to safety concerns raised by the trial's Independent Data Monitoring Committee (IDMC).
The IDMC recommended the suspension following a review of safety data that included four fatal serious adverse events (SAEs) in trial participants from the Philippines and Argentina. Kezar expects to receive a formal clinical hold letter from the FDA within 30 days outlining the agency's concerns and requirements for resuming the trial.
Despite this setback, Kezar's Chief Executive Officer, Chris Kirk, PhD, reaffirmed the company's commitment to patient safety and the continuation of the zetomipzomib development program. The IND for zetomipzomib in the treatment of autoimmune hepatitis remains unaffected, with the ongoing Phase 2a PORTOLA clinical trial not having reported any Grade 4 or 5 SAEs to date.
Lupus nephritis is a severe manifestation of systemic lupus erythematosus, affecting around half of SLE patients within ten years of diagnosis. It can lead to end-stage renal disease and significantly increases the risk of death. Current management of LN involves induction therapy for remission and maintenance therapy to prevent relapse, with few approved treatments available.
The news of the clinical hold could have implications for investors and the biotech industry, as safety concerns in clinical trials can impact drug development timelines and company valuations. Kezar Life Sciences is actively investigating the cases to address the FDA's concerns and is focused on advancing its portfolio of treatments for immune-mediated diseases. This report is based on a press release statement from Kezar Life Sciences, Inc.
In other recent news, Kezar Life Sciences has experienced significant developments. The company reported a second-quarter net loss of $22 million with cash reserves of $164 million, expected to sustain the company until late 2026. Enrollment and dosing in its Phase 2b trial of zeto for lupus nephritis were paused following serious adverse events resulting in fatalities. Despite these challenges, Kezar's Phase IIa PORTOLA study in autoimmune hepatitis (AIH) continues, with results anticipated in the first half of 2025.
The company has also decided to discontinue the development of another drug candidate, KZR-261, to focus its resources on zeto's trials. Under a licensing agreement with Everest Medicines, the first patient in China has been dosed with zeto. TD Cowen and Jones Trading have maintained their respective Buy and Hold ratings for Kezar Life Sciences amidst these developments.
These are recent developments, and the company is currently reviewing safety data and considering risk mitigation strategies for zeto's development in lupus nephritis. The company's strategic decisions and financial position have been noted by analysts from TD Cowen, who reiterated a Buy rating for the company.

The recent clinical hold on Kezar Life Sciences' (NASDAQ:KZR) zetomipzomib trial for lupus nephritis has undoubtedly impacted the company's near-term prospects. However, a closer look at the company's financial metrics and market performance reveals a complex picture.
According to InvestingPro data, Kezar's market capitalization stands at $56.76 million, reflecting the market's current valuation of the company. Despite the setback in its lupus nephritis program, the company has shown resilience in its stock performance. InvestingPro Tips highlight that KZR has seen a significant return over the last week, with a 51.79% price total return. This short-term surge suggests that investors may be seeing potential beyond the current clinical hold.
It's worth noting that Kezar holds more cash than debt on its balance sheet, which could provide some financial flexibility as it navigates the challenges posed by the FDA's decision. This cash position may be crucial as the company works to address the safety concerns and potentially resume its clinical trials.
However, investors should be aware that Kezar is quickly burning through cash, as indicated by another InvestingPro Tip. This burn rate is reflected in the company's financials, with a negative gross profit margin of -1040.71% for the last twelve months as of Q2 2024. The company's revenue for the same period was $7 million, while its operating income was -$99.54 million, underscoring the significant investment in research and development typical of biotech firms in the clinical stage.
For those considering an investment in Kezar, it's important to note that analysts do not anticipate the company will be profitable this year. This aligns with the current stage of Kezar's drug development pipeline and the recent setback with the zetomipzomib trial.
