SAN FRANCISCO, March 12, 2020 (GLOBE NEWSWIRE) -- Kezar Life Sciences, Inc. (Nasdaq: KZR), a clinical-stage biotechnology company discovering and developing novel small molecule therapeutics to treat unmet needs in autoimmunity and cancer, today announced its fourth quarter and year end 2019 financial results and corporate highlights.
“2019 marked several key milestones for Kezar, and I’m grateful for our team’s skill and hard work moving both of our programs forward. Our selective immunoproteasome inhibitor, KZR-616, entered Phase 2 trials in five different autoimmune diseases of high unmet need, building upon encouraging data from our ongoing Phase 1b study. We also nominated KZR-261, the first clinical candidate from our protein secretion program, and expect an IND filing in early 2021”, said John Fowler, Chief Executive Officer. “This year we look forward to sharing updates from the Phase 1b portion of our MISSION study, as well as an interim analysis from our MARINA trial in AIHA and ITP. Finally, after our successful financing last month, we have a strong cash position that takes us beyond all of our KZR-616 Phase 2 readouts as well as data with KZR-261 in multiple tumor types.”
Recent Clinical and Business Highlights
KZR-616 – Selective Immunoproteasome Inhibitor
The Phase 1b/2 MISSION study in systemic lupus erythematosus (SLE) patients with and without nephritis is currently ongoing.
- Additional data from the Phase 1b portion of MISSION will be presented during various medical conferences throughout the course of 2020.
- The Phase 2 portion of MISSION is a randomized, placebo-controlled, double-blind trial to evaluate the safety and efficacy of KZR-616 in patients with active proliferative lupus nephritis. The primary endpoints of this portion of the MISSION trial are safety and tolerability. Secondary and exploratory endpoints include pharmacokinetics (PK), pharmacodynamics (PD), biomarker assessments and additional measures of efficacy. This trial includes four treatment arms evaluating KZR-616 administered subcutaneously once weekly for 24 weeks at dose levels of 30 mg, 45 mg and 60 mg, compared to placebo. The trial is designed to enroll up to 64 patients.
The Phase 2 MARINA study in patients with autoimmune hemolytic anemia (AIHA) or immune thrombocytopenia (ITP) is currently ongoing.
- MARINA is a Phase 2 randomized, dose-blind, multicenter trial designed to evaluate the safety, tolerability, efficacy, PK and PD of KZR-616 in patients with active AIHA or ITP. Patients with AIHA or ITP will be randomized to receive either 30 mg or 45 mg of KZR-616 subcutaneously once weekly for 13 weeks, followed by 12 weeks of follow-up. The trial is designed to enroll up to 40 patients. Kezar believes that whole blood RNASeq data from the Phase 1b portion of MISSION, which showed a decrease in multiple inflammatory gene signature and prolonged increase in erythropoietic gene signatures in SLE patients, support the broad potential anti-inflammatory activity of KZR-616 and therapeutic potential in patients with AIHA.
The Phase 2 PRESIDIO study in patients with polymyositis (PM) or dermatomyositis (DM) is currently ongoing.
- PRESIDIO is a Phase 2 randomized, placebo-controlled, double-blind, crossover, multicenter trial to evaluate the safety, tolerability, efficacy, PK and PD of KZR-616 in patients with active PM or DM. During the 32-week treatment period, patients receive either 45 mg of KZR-616 or placebo subcutaneously once weekly for 16 weeks followed by a crossover to the other treatment arm for an additional 16 weeks. The trial is designed to enroll up to 24 patients. Kezar believes that KZR-616 has the potential to be developed into a treatment for patients with DM and PM, which is in-part supported by preclinical data in a mouse model of PM and DM that demonstrated immunoproteasome inhibition and improved muscle function.
KZR-261 – Protein Secretion Program
- Research and discovery efforts targeting the protein secretion pathway have progressed significantly, and this novel program and pathway was featured in four separate presentations during two major medical and scientific conferences in 2019: the Society for Immunotherapy of Cancer (SITC) and the 61st American Society of Hematology Meeting & Exposition (ASH).
- KZR-261, our first oncology clinical candidate and a first-in-class protein secretion inhibitor, has demonstrated broad anti-tumor activity in preclinical models of both solid and hematologic malignancies. Kezar anticipates filing an Investigational New Drug (IND) application for a Phase 1 study of KZR-261 in solid tumors in the first quarter of 2021.
On February 4, 2020, Kezar completed an underwritten public offering of 18,965,385 shares of its common stock, which includes the full exercise of the underwriters’ option, and pre-funded warrants to purchase 2,884,615 shares of its common stock at an exercise price of $0.001 per share. The public offering price of the common stock was $2.60 per share and the public offering price of each pre-funded warrant was $2.599 per underlying share. The gross proceeds from the public offering were approximately $56.8 million, before deducting underwriting discounts and offering expenses.
- Cash, cash equivalents and marketable securities totaled $78.2 million as of December 31, 2019, compared to $107.4 million as of December 31, 2018. The decrease in cash, cash equivalents and marketable securities was primarily attributable to cash used by the company in operations to advance its clinical stage programs as well as preclinical research and development.
- Research and development expenses for the fourth quarter of 2019 increased by $2.7 million to $7.4 million compared to $4.7 million in the fourth quarter of 2018. Full year R&D expenses increased by $9.2 million in 2019 compared to 2018. This increase was primarily related to advancing the KZR-616 clinical program in multiple indications and the protein secretion preclinical program.
- General and administrative expenses for the fourth quarter of 2019 increased by $0.8 million to $2.6 million compared to $1.8 million in the fourth quarter of 2018. Full year G&A expenses increased by $3.4 million in 2019 compared to 2018. The increase was primarily due to an increase in personnel expenses and costs related to operating as a public company.
- Net loss for the fourth quarter of 2019 was $9.6 million, or $0.50 per basic and diluted common share, compared to a net loss of $5.8 million, or $0.30 per basic and diluted common share, for the fourth quarter of 2018. Net loss for 2019 was $35.1 million, or $1.84 per basic and diluted common share, compared to $23.2 million, or $2.26 per basic and diluted common share, in 2018.
- Total shares outstanding were 19.2 million as of December 31, 2019. Additionally, there were outstanding options to purchase 3.1 million shares of common stock at a weighted average exercise price of $7.19 per share as of December 31, 2019.
KZR-616 is a novel, first-in-class, selective immunoproteasome inhibitor with broad therapeutic potential across multiple autoimmune diseases. Preclinical research demonstrates that selective immunoproteasome inhibition results in a broad anti-inflammatory response in animal models of several autoimmune diseases, while avoiding immunosuppression. Phase 1a clinical trial results in healthy volunteers provide evidence that KZR-616 potentially avoids adverse effects caused by currently marketed non-selective proteasome inhibitors, which Kezar believes prevent them from being utilized as a chronic treatment in autoimmune disorders. Phase 2 trials are underway for the treatment of lupus nephritis (MISSION study), autoimmune hemolytic anemia and immune thrombocytopenia (MARINA study), and dermatomyositis and polymyositis (PRESIDIO study).
KZR-261, a novel, first-in-class protein secretion inhibitor, is the first clinical candidate to be nominated from Kezar’s research and discovery efforts targeting protein secretion pathways. KZR-261 is a broad-spectrum anti-tumor agent that acts through direct interaction and inhibition of Sec61 activity. The compound was discovered at Kezar through a robust medicinal chemistry campaign in which several scaffolds were progressed through the company’s proprietary platform evaluating Sec61 modulation. As a result, Kezar has established a broad library of protein secretion inhibitors. KZR-261 has demonstrated several encouraging properties that lead to its potential to be an anti-cancer agent for the treatment of solid and hematologic malignancies. IND-enabling activities are currently underway, and an IND application in solid tumors is expected to be filed in the first quarter of 2021.
