Financial Analyst

Xenon Pharmaceuticals reported mixed Q2 2024 results. While R&D expenses increased to $49.7 million from $44.0 million last year, driven by pre-clinical programs and higher personnel costs, the company maintains a strong cash position of $850.6 million. This is expected to fund operations into 2027, covering key clinical milestones.

The net loss widened to $57.9 million from $47.5 million, primarily due to higher R&D and G&A expenses. However, other income increased to $10.8 million, mainly from higher interest income. The company's focus on advancing its pipeline, particularly azetukalner, while maintaining a solid financial position, suggests a balanced approach to growth and fiscal management.

Medical Research Analyst

Xenon's lead candidate azetukalner (XEN1101) is progressing well in multiple indications. The Phase 3 X-TOLE2 trial for focal onset seizures is on track with topline data expected in H2 2025. This, along with the ongoing X-ACKT trial for primary generalized tonic-clonic seizures, positions azetukalner as a potential game-changer in epilepsy treatment.

The company is also expanding azetukalner's potential into major depressive disorder (MDD), with a Phase 3 study set to start in H2 2024. This multi-indication approach, coupled with the extended 7-year open-label extension study generating long-term data, strengthens azetukalner's clinical profile. The advancement of multiple Kv7 and Nav1.7 candidates towards IND filings in 2025 further diversifies Xenon's neuroscience pipeline.

Mr. Mortimer continued, “Beyond azetukalner, we continue to build upon our Kv7 leadership with a broad portfolio of diverse chemistries to support our ‘pipeline in a mechanism’ approach. In parallel, we are advancing promising Nav1.7 candidates towards early human proof-of-concept in pain. We believe that the advancements in our azetukalner development programs in epilepsy and MDD, with our maturing pre-clinical pipeline, position Xenon with one of the most exciting CNS portfolios that exists today.”

Quarterly Business Highlights and Anticipated Milestones

Azetukalner Clinical Development

Azetukalner (XEN1101) is a novel, potent Kv7 potassium channel opener being developed for the treatment of epilepsy, including focal onset seizures (FOS) and primary generalized tonic-clonic seizures (PGTCS), as well as major depressive disorder (MDD), with the Company exploring applicability in other neuropsychiatric disorders.

• Phase 3 FOS studies continue to advance, with the first topline data readout from X-TOLE2 anticipated in the second half of 2025. The Phase 3 FOS clinical trials are multicenter, randomized, double-blind, placebo-controlled studies evaluating the clinical efficacy, safety, and tolerability of azetukalner in patients with FOS.
• Phase 3 X-ACKT clinical trial is currently enrolling patients and is intended to support potential regulatory submissions in an additional epilepsy indication of PGTCS. This multicenter, randomized, double-blind, placebo-controlled trial is evaluating the clinical efficacy, safety and tolerability of azetukalner in patients with PGTCS.
• X-TOLE Phase 2b open-label extension (OLE) has been extended to seven years and continues to generate important long-term data for azetukalner beyond the 600 patient-years of exposure to date. Upon completion of the double-blind period in the Phase 3 epilepsy studies, eligible patients may enter an OLE study for up to three years.
• The Company presented Phase 2 X-NOVA data at the American Society of Clinical Psychopharmacology (ASCP) meeting in May. The X-NOVA study evaluated azetukalner in patients with MDD. The first of three planned Phase 3 clinical trials is expected to initiate in the second half of 2024.
• Xenon will present three epilepsy related posters at the upcoming 15th European Epilepsy Congress in Rome, Italy from September 7 to 11. The Company will also present a poster on MDD at the Psych Congress in Boston, MA from October 29 to November 2.
• The Company continues to support the investigator-sponsored Phase 2 proof-of-concept study of azetukalner in MDD led by Icahn School of Medicine at Mount Sinai, with patient enrollment anticipated to complete this quarter.

Early-Stage Pipeline: Next Generation Ion Channel Modulators

As leaders in the small molecule ion channel space, Xenon continues to leverage its extensive expertise to discover and develop potassium and sodium channel therapeutics. The Company is evaluating multiple therapeutic candidates targeting Kv7, Nav1.7, and Nav1.1 across various indications with the goal of filing multiple INDs, or equivalent, in 2025.

• The Company has nominated multiple Kv7 development candidates, with a lead candidate in IND-enabling studies. Kv7 may have utility in a broad range of therapeutic indications including seizures, pain, and neuropsychiatric disorders, such as MDD.
• A lead Nav1.7 candidate is expected to enter IND-enabling studies in the near term. Nav1.7 is an important pain-related target, based on strong human genetic validation, that may represent a new class of medicines without the limitations of opioids.
• The Company expects to nominate a lead Nav1.1 candidate, as pre-clinical data suggests that targeting Nav1.1 could potentially address the underlying cause and symptoms of Dravet Syndrome.

Partnered Program

• As part of Xenon’s ongoing collaboration with Neurocrine Biosciences to develop treatments for epilepsy, a Phase 2 clinical trial is evaluating NBI-921352 (formerly XEN901) in an orphan pediatric epilepsy (SCN8A-DEE), and the next lead candidate, a Nav1.2/1.6 inhibitor, is in IND-enabling studies with the intent to progress into human clinical trials in 2025 as a potential treatment for focal onset seizures. 

Second Quarter Financial Results

• Cash and cash equivalents and marketable securities were $850.6 million as of June 30, 2024, compared to $930.9 million as of December 31, 2023. Based on current operating plans, including the completion of the azetukalner Phase 3 epilepsy studies and fully supporting late-stage clinical development of azetukalner in MDD, Xenon anticipates having sufficient cash to fund operations into 2027. As of June 30, 2024, there were 75,667,550 common shares and 2,173,081 pre-funded warrants outstanding.
• Research and development expenses for the quarter ended June 30, 2024 were $49.7 million, compared to $44.0 million for the same period in 2023. The increase of $5.7 million was primarily attributable to increased expenses related to our pre-clinical and discovery programs to advance multiple potential drug candidates targeting Kv7, Nav1.7, and Nav1.1, increased personnel-related costs due to an increase in employee headcount, and higher stock-based compensation expense. These increases were partially offset by a decrease in expenses for the XEN496 program as a result of Xenon's decision in early 2023 to no longer pursue the clinical development of XEN496.
• General and administrative expenses for the quarter ended June 30, 2024 were $19.4 million, compared to $11.6 million for the same period in 2023. The increase of $7.8 million was primarily attributable to personnel-related costs due to an increase in employee headcount and higher stock-based compensation expense, and an increase in professional and consulting fees.
• Other income for the quarter ended June 30, 2024 was $10.8 million, compared to $7.9 million for the same period in 2023. The increase of $2.9 million was primarily attributable to higher interest income, partially offset by a decrease in the unrealized fair value gain on trading securities.
• Net loss for the quarter ended June 30, 2024 was $57.9 million, compared to $47.5 million for the same period in 2023. The increase in net loss was primarily attributable to higher research and development expenses driven by pre-clinical and discovery programs, and increased personnel-related costs and stock-based compensation expense across the organization, partially offset by an increase in interest income.

About the Azetukalner Phase 3 Epilepsy Program

Xenon’s Phase 3 epilepsy program includes three ongoing Phase 3 clinical trials in focal onset seizures (FOS) and primary generalized tonic-clonic seizures (PGTCS). Designed closely after the Phase 2b X-TOLE clinical trial, the Phase 3 X-TOLE clinical trials are multicenter, randomized, double-blind, placebo-controlled studies evaluating the clinical efficacy, safety, and tolerability of 15 mg or 25 mg of azetukalner administered with food as adjunctive treatment in approximately 360 patients with FOS per study. The primary efficacy endpoint is the median percent change (MPC) in monthly seizure frequency from baseline through the double-blind period (DBP) of azetukalner compared to placebo. X-ACKT is a multicenter, randomized, double-blind, placebo-controlled study evaluating the clinical efficacy, safety, and tolerability of 25 mg of azetukalner administered with food as adjunctive treatment in approximately 160 patients with PGTCS. The primary efficacy endpoint is the MPC in monthly PGTCS frequency from baseline through the DBP of azetukalner compared to placebo.

About the Azetukalner Phase 3 Major Depressive Disorder (MDD) Program

Xenon completed its Phase 2 proof-of-concept X-NOVA clinical trial, which evaluated the clinical efficacy, safety, and tolerability of 10 mg and 20 mg of azetukalner in 168 patients with moderate to severe MDD. The primary objective was to assess the efficacy of azetukalner compared to placebo on improvement of depressive symptoms using the Montgomery-Åsberg Depression Rating Scale (MADRS) score change through week 6. Based on X-NOVA results, Xenon plans on initiating the first of three Phase 3 clinical trials in MDD in the second half of 2024.
