CAMBRIDGE, Mass., Nov. 10, 2022 (GLOBE NEWSWIRE) -- Wave Life Sciences Ltd. (Nasdaq: WVE), a clinical-stage genetic medicines company committed to delivering life-changing treatments for people battling devastating diseases, today announced financial results for the third quarter ended September 30, 2022 and provided a business update.

“In the third quarter, we continued to deliver on our key milestones for 2022, including announcing a positive update from our Huntington’s disease trial and selecting our first-in-class RNA editing candidate for alpha-1 antitrypsin deficiency,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. “Clinical data emerging from our pipeline supports the translational potential of our unique PRISM platform and we look forward to sharing a third data update this quarter with the first muscle biopsy data from our Phase 1b/2a clinical trial of WVE-N531 for Duchenne muscular dystrophy. Additionally, we believe that our RNA editing capability using endogenous ADAR enzymes provides a unique opportunity for Wave and we are well-positioned to be leaders in the editing field. We are working toward bringing RNA editing to the clinic and are on track to submit clinical trial applications for our alpha-1 antitrypsin deficiency program in 2023.”

Recent Pipeline and Business Highlights

SELECT-HD clinical trial for WVE-003 in Huntington’s disease (HD) continues to advance; only allele-selective clinical program designed to reduce mutant HTT and spare healthy HTT

  • WVE-003 (PN-modified allele-selective silencing oligonucleotide) for HD is being evaluated in the ongoing, adaptive, double-blind Phase 1b/2a SELECT-HD clinical trial (NCT05032196). WVE-003 is the only compound in clinical development designed to selectively lower mutant huntingtin (mHTT) protein levels, while leaving wild-type (healthy) huntingtin (wtHTT) protein levels relatively intact.
  • In September 2022, Wave announced a positive update from the company’s ongoing SELECT-HD clinical trial driven by the observation of reductions in mHTT protein in cerebrospinal fluid (CSF) after study participants received either a single 30 or 60 mg dose of WVE-003. Additionally, wtHTT protein was preserved, which appeared consistent with allele-selectivity. Single doses of WVE-003 appeared generally safe and well-tolerated.
  • Based on the SELECT-HD data, Wave is adapting the trial to expand the single dose cohorts, including in a 90 mg single dose cohort for which biomarker data were not available at the time of analysis. Wave expects to share additional single-dose biomarker and safety data in the first half of 2023.
  • In November 2022, these SELECT-HD data were presented in an oral presentation at the Huntington Study Group (HSG) Annual Meeting in Tampa, Florida.

Phase 1b/2a clinical trial of WVE-N531 in Duchenne muscular dystrophy (DMD) amenable to exon 53 skipping continues to advance; multi-dosing is underway at human-equivalent levels in the range explored in preclinical double-knockout (dKO) mouse

  • WVE-N531 (PN-modified splicing oligonucleotide) for DMD is being evaluated in an open-label, intra-patient dose escalation clinical trial (NCT04906460). Dose escalation is complete and multi-dosing is underway with three 10 mg/kg doses of WVE-N531 every other week, to be followed by planned muscle biopsies. Clinical biomarker and safety data is expected in the fourth quarter of 2022. Possible cohort expansion will be informed by an assessment of the concentration and distribution of WVE-N531 in muscle tissue, as well as biomarkers, including exon skipping and dystrophin.
  • Plasma concentrations and half-life of WVE-N531 observed in patients receiving 10 mg/kg of WVE-N531 in Wave’s ongoing clinical trial were significantly greater than plasma concentrations achieved following the highest doses of suvodirsen, Wave’s first-generation PS/PO exon skipping compound administered in a Phase 2/3 study. This pharmacokinetic analysis suggests the potential for significantly improved pharmacologic properties of WVE-N531, including distribution and stability in muscle.

FOCUS-C9 clinical trial of WVE-004 for C9orf72-associated amyotrophic lateral sclerosis and frontotemporal dementia (C9-ALS and C9-FTD) continues to advance; open-label extension trial recently initiated

  • FOCUS-C9 (NCT04931862) is an adaptive Phase 1b/2a clinical trial that is designed to rapidly optimize dose level and frequency based on early indicators of target engagement. WVE-004 is designed to selectively target transcript variants containing a hexanucleotide repeat expansion (G4C2) associated with the C9orf72 gene for the treatment of C9-ALS and C9-FTD, thereby reducing pathological mRNA products and toxic DPR proteins, including poly(GP).
  • Based on potency and durability of pharmacodynamic effects, the multidose portion of the FOCUS-C9 trial was expanded to evaluate quarterly dosing. Data from all cohorts in the FOCUS-C9 clinical trial are expected in the first half of 2023.
  • In November 2022, Wave presented previously disclosed clinical data from the ongoing FOCUS-C9 clinical trial at the International Society for Frontotemporal Dementias in Lille, France.
  • An open-label extension trial for participants in the FOCUS-C9 trial was initiated in the fourth quarter of 2022.

Alpha-1 antitrypsin deficiency (AATD) development candidate (WVE-006) designed to correct mutant AATD transcript to address both liver and lung manifestations of disease highlighted at virtual event

  • In the third quarter, Wave selected WVE-006 (PN-modified GalNAc-conjugated development candidate) as its development candidate for the treatment of AATD. In September 2022, Wave highlighted WVE-006 in a virtual event, “Towards the Clinic: Spotlight on RNA Editing for AATD.” The event replay is available here. WVE-006 is Wave’s first AIMer (A-to-I(G) RNA base editing oligonucleotide) development candidate. WVE-006 is first-in-class in AATD and is the most advanced program currently in development using an oligonucleotide to harness an endogenous enzyme for editing.
  • In October 2022, preclinical data for WVE-006 was highlighted in an oral presentation at the 18th Annual Meeting of the Oligonucleotide Therapeutics Society (OTS). The meeting represented the first presentation in a scientific congress of preclinical data supporting WVE-006 as a potential best-in-class therapeutic approach in AATD. The OTS presentation slides are available here.

PRISM platform: RNA editing and small interfering RNA (siRNA) capabilities highlighted across six presentations and posters at recent scientific congresses

  • Wave’s preclinical-stage siRNA designs, which incorporate PRISM chemistry, were highlighted at the OTS Meeting in October 2022. The OTS poster is available here. The data demonstrated remarkably robust and durable RNA silencing in vivo in mice, further illustrating the evolution and the potential of Wave’s chemistry.
  • Wave’s application of ADAR-mediated RNA editing to modulate protein-protein interactions in mice was also highlighted in a poster accepted at the European Society of Gene and Cell Therapy (ESGCT) meeting in October 2022. The ESGCT poster is available here.

Key Anticipated Upcoming Milestones

WVE-003 for HD:

  • Additional single-dose biomarker and safety clinical data expected in 1H 2023.

WVE-N531 for DMD:

  • Clinical data, including muscle biopsies, expected in 4Q 2022 to provide further insight into the clinical effects of PN chemistry and enable decision-making for this program.

WVE-004 for C9-ALS and C9-FTD:

  • Clinical data from all cohorts in the FOCUS-C9 trial expected in 1H 2023.

WVE-006 (GalNAc-conjugated AIMer) for AATD:

  • Wave expects to submit clinical trial applications (CTAs) in 2023.

Third Quarter 2022 Financial Results and Financial Guidance
Wave reported a net loss of $39.0 million in the third quarter of 2022, as compared to $6.2 million in the same period in 2021. Wave recorded revenue of $0.3 million for the third quarter of 2022, as compared to $36.4 million in the same period in 2021. The decrease in revenue year-over-year was primarily driven by the amendment to the Takeda Collaboration in the third quarter of 2021.

Research and development expenses were $27.6 million in the third quarter of 2022 as compared to $31.1 million in the same period in 2021. The decrease in research and development expenses in the third quarter was primarily due to decreased external expenses related to our HD programs and decreases in other research and development expenses, partially offset by increased external expenses related to C9 and our other clinical and preclinical programs.

General and administrative expenses were $11.6 million in the third quarter of 2022 as compared to $12.9 million in the same period in 2021. The decrease in general and administrative expenses in the third quarter of 2022 was primarily due to decreases in compensation-related expenses, as well as decreases in other external general and administrative expenses.

As of September 30, 2022, Wave had $122.0 million in cash, cash equivalents and short-term investments. As of December 31, 2021, Wave had $150.6 million in cash and cash equivalents. The decrease is primarily due to Wave’s year to date operating cash burn, partially offset by $65.5 million in net proceeds from its financing in June 2022.

Wave expects that its existing cash, cash equivalents and short-term investments will enable the company to fund its operating and capital expenditure requirements to the end of 2023.

About the SELECT-HD Clinical Trial
The SELECT-HD trial is a global, multicenter, randomized, double-blind, placebo-controlled Phase 1b/2a clinical trial to assess the safety and tolerability of single- and multiple-ascending intrathecal doses of WVE-003 in people with a confirmed diagnosis of HD who are in the early stages of the disease and carry SNP3 in association with their cytosine-adenine-guanine (CAG) expansion. Additional objectives include assessing the plasma pharmacokinetic profile and exposure in the cerebrospinal fluid, as well as exploratory pharmacodynamic (mHTT, wtHTT and neurofilament light chain) and clinical endpoints. It is designed to be adaptive, with dose escalation and dosing frequency being guided by an independent committee.

In an initial data analysis, single doses of WVE-003 up to 90 mg appeared generally safe and well-tolerated. Adverse events (AEs) were balanced across treatment groups, including placebo, and all were mild to moderate in intensity. No serious adverse events (SAEs) were observed and no participants discontinued from the study. Among participants in the 30 and 60 mg WVE-003 cohorts, the mean reduction in CSF mHTT from baseline was 22% (median reduction 30%) at 85 days following a single dose. The difference in the mean reduction in CSF mHTT compared to placebo was 35% at 85 days post-single dose. For these analyses, the 30 and 60 mg single dose cohorts were pooled as there was no apparent dose response between these two cohorts. Wave will continue to evaluate dose response in the expanded single dose cohorts. In the 30 and 60 mg cohorts, wtHTT protein was preserved, which appears consistent with allele-selectivity. Increases in neurofilament light chain (NfL) from baseline were observed in some participants. Wave will continue to monitor trends in NfL as SELECT-HD advances. There were no clinically meaningful elevations in CSF white blood cell counts or protein that would indicate inflammation in the CNS. There were no meaningful changes in clinical outcome measures, although the dataset and duration were not sufficient to assess clinical effects.

About the FOCUS-C9 Clinical Trial
The FOCUS-C9 trial is an ongoing, global, multicenter, randomized, double-blind, placebo-controlled Phase 1b/2a clinical trial to assess the safety and tolerability of single- and multiple-ascending intrathecal doses of WVE-004 for people with C9-ALS and/or C9-FTD. Additional objectives include measurement of poly(GP) DPR proteins in the cerebrospinal fluid (CSF), plasma and CSF pharmacokinetics (PK), and exploratory biomarkers and clinical outcomes. The FOCUS-C9 trial is designed to be adaptive, with dose escalation and dosing frequency being guided by an independent committee.

In an initial data analysis, reductions in poly(GP) were observed across all active treatment groups (10 mg, n=2 patients; 30 mg, n=4 patients; 60 mg, n=3 patients), reaching statistical significance versus placebo (n=3 patients) after single 30 mg doses, with a 34% reduction in poly(GP) at day 85 (p=0.011). At the time of analysis, none of the patients dosed with 60 mg had reached day 85. As the poly(GP) reduction in the 30 mg single dose cohort does not appear to have plateaued, Wave will extend the observation period from approximately three months (85 days) to approximately six months to identify the maximum reduction of poly(GP) and duration of effect of low single doses. Based on the durability and potency observed in the 30 mg cohort, FOCUS-C9 has been adapted to include additional patients receiving 20 mg and 30 mg single doses of WVE-004. Adverse events (AEs) were balanced across treatment groups, including placebo, and were mostly mild to moderate in intensity. Four patients (including one on placebo) experienced severe and/or serious adverse events; three were reported by the investigators to be related to ALS or administration, and one was reported by the investigator to be related to study drug. There were no treatment-associated elevations in CSF white blood cell counts or protein and no other notable laboratory abnormalities were observed.

Support for FOCUS-C9 is provided by the Alzheimer’s Drug Discovery Foundation.
