Clinical Highlights & Updates

KZR-616: Selective Immunoproteasome Inhibitor

MISSION – Phase 2 clinical trial in patients with lupus nephritis (LN) (NCT03393013)

At the European Congress of Rheumatology (EULAR 2021) in June, Kezar presented final clinical data from the completed Phase 1b dose escalation portion of the MISSION study in 47 patients with systemic lupus erythematous, including two patients with active proliferative LN. KZR-616 demonstrated improvement across all exploratory efficacy measures and was well-tolerated up to 75 mg subcutaneously once weekly for 13 weeks. In the two patients with LN, improvements in renal function correlated with reductions in a key biomarker of kidney inflammation, uCD163.

• The safety and tolerability profile observed with KZR-616 was consistent with previously reported data and supports treatment for chronic use. No new safety or tolerability signals were observed from previously reported data.
• These data support the development of KZR-616 in multiple immune-mediated diseases.
  • Doses being investigated in the Phase 2 clinical trials are 60 mg (MISSION Phase 2 in LN) and 45 mg (PRESIDIO Phase 2 in dermatomyositis and polymyositis) with weekly subcutaneous dosing.
• The amended Phase 2 open-label portion of the MISSION trial in patients with active, proliferative LN opened for enrollment in August 2020 and is actively recruiting. The primary efficacy endpoint for the trial is the proportion of patients achieving a renal response measured by a 50% or greater reduction in urine protein to creatinine ratio (UPCR) at six months.
  • Kezar reiterates prior guidance and expects interim data to be reported in Q4 2021, and topline data are expected in the first half of 2022.

PRESIDIO – Phase 2 clinical trial in patients with dermatomyositis (DM) and polymyositis (PM) (NCT04033926)

• The PRESIDIO Phase 2, placebo controlled cross-over trial of KZR-616 in DM and PM is actively enrolling. Additionally, a 12-month open-label extension study is open to patients completing the 32-week placebo-controlled trial (NCT04628936).
  • Topline data are expected in the first half of 2022.

KZR-261: Protein Secretion Inhibitor

• KZR-261 is a first-in-class protein secretion inhibitor that targets the Sec61 translocon and has demonstrated broad anti-tumor activity in preclinical models of both solid and hematologic malignancies.
  • Kezar submitted an investigational new drug (IND) application for KZR-261 to the U.S. Food and Drug Administration (FDA) in August 2021. The company plans to initiate a Phase 1 clinical trial of KZR-261, which will assess safety, tolerability and preliminary tumor activity of KZR-261 in solid tumors.
  • At the American Association of Cancer Research (AACR) 2021 Virtual Annual Meeting in April, Kezar presented preclinical data on its novel small molecule inhibitors of the Sec61 translocon. These data support the therapeutic potential of inhibiting Sec61 and the protein secretion pathway as a way to generate novel therapies to treat multiple tumor indications.

Corporate Updates

• Kezar formed a Clinical Advisory Committee in June, comprised of world-renowned thought leaders in immunology, rheumatology, neurology and nephrology. Appointments to the committee include: Rohit Aggarwal, MD, MS, Professor of Medicine, University of Pittsburgh; Prof. Olivier Benveniste, MD, PhD, Professor of Internal Medicine & Immunology, Sorbonne Université, Pitie Salpetriere Hospital; Mazen Dimachkie, MD, Professor of Neurology, University of Kansas Medical Center; Ingrid Lundberg, MD, PhD, Professor of Medicine, Karolinska Institute; Samir V. Parikh, MD, Assistant Professor of Medicine, Ohio State University Wexner Medical Center; and Onno Teng, MD, PhD, Nephrology Clinical Scientist, Leiden University Medical Center.

• Micki Klearman, MD, rheumatologist and internist, was appointed to Kezar’s Board of Directors, bringing over two decades of biopharmaceutical experience with her significant contributions to the fields of immunology and rheumatology.

Second Quarter 2021 Financial Results

• Cash, cash equivalents and marketable securities totaled $129 million as of June 30, 2021, compared to $140 million as of December 31, 2020. 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 and preclinical research and development, offset by the net proceeds from the issuance of common stock in February 2021, under the “at-the-market” Sales Agreement with Cowen and Company, LLC.
• Research and development expenses for the second quarter of 2021 increased by $2.2 million to $9.3 million compared to $7.1 million in the second quarter of 2020. 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 second quarter of 2021 increased by $1.0 million to $3.7 million compared to $2.7 million in the second quarter of 2020. The increase was primarily due to an increase in stock-based compensation and personnel and recruiting expenses as a result of an increase in headcount and salaries and an increase in the cost of directors’ and officers’ liability insurance.
• Net loss for the second quarter of 2021 was $13.0 million, or $0.25 per basic and diluted common share, compared to a net loss of $9.5 million, or $0.22 per basic and diluted common share, for the second quarter of 2020.
• Total shares of common stock outstanding were 48.1 million shares as of June 30, 2021. Additionally, there were outstanding pre-funded warrants to purchase 3.8 million shares of common stock at an exercise price of $0.001 per share and outstanding options to purchase 7.3 million shares of common stock at a weighted-average exercise price of $5.86 per share as of June 30, 2021.

About KZR-616

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. Data generated from Phase 1a and 1b clinical trials provide evidence that KZR-616 exhibits a favorable safety and tolerability profile for development in severe, chronic autoimmune diseases. Phase 2 trials are underway in severe autoimmune diseases.

About KZR-261

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 pathway. KZR-261 is a broad-spectrum anti-tumor agent that acts through direct interaction and inhibition of Sec61 activity. The compound was discovered by 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. An IND submission in solid tumors was filed in August 2021 and a Phase 1 trial is expected to commence once the IND goes into effect.

About Lupus Nephritis

Lupus nephritis (LN) is one of the most serious complications of systemic lupus erythematosus. LN is a disease comprising a spectrum of vascular, glomerular and tubulointerstitial lesions and develops in approximately 50% of SLE patients within 10 years of their initial diagnosis. LN is associated with considerable morbidity, including an increased risk of end-stage renal disease requiring dialysis or renal transplantation and an increased risk of death. There are limited approved therapies for the treatment of LN. Management typically consists of induction therapy to achieve remission and long-term maintenance therapy to prevent relapse.

About Dermatomyositis and Polymyositis

Dermatomyositis (DM) and Polymyositis (PM) are two of the five types of autoimmune myositis diseases. Both are chronic, debilitating, inflammatory autoimmune myopathies that are distinguished by inflammation of the muscles as well as the skin (in DM). Approximately 30,000 to 120,000 people in the United States are living with these severe and progressive inflammatory myopathies that are characterized by marked morbidity and associated mortality. While debilitating muscle weakness is the hallmark of these myopathies, including compromised muscles of respiration, other internal organ system dysfunctions can be equally disabling. The aim of treatment for these diseases is to suppress inflammation, increase muscle strength and prevent long-term damage to muscles and extramuscular organs; however, treatment options are limited for DM, and there are currently no approved treatments for PM.
