Wave to host investor conference call and webcast at 8:30 a.m. ET today
CAMBRIDGE, Mass., May 12, 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 first quarter ended March 31, 2022 and provided a business update.
“Thus far in 2022, Wave has achieved several important milestones, with the highlight being our first clinical data demonstrating successful target engagement with WVE-004 in the ongoing FOCUS-C9 clinical trial for C9-ALS and C9-FTD. We observed potent and durable reductions of the poly(GP) biomarker with low single doses of WVE-004, demonstrating that our preclinical data for PN-containing oligonucleotides are beginning to translate in the clinic,” said Paul Bolno, MD, MBA, President and Chief Executive Officer of Wave Life Sciences. “These initial results are compelling and reinforce the potential of our unique oligonucleotide platform and our expectation to see the advantages of PN chemistry manifest in our other pipeline programs. We also continue to rapidly advance our WVE-003 program for HD and WVE-N531 program for DMD towards initial data updates later this year. We are also pleased with the recognition we are receiving with our endogenous RNA editing modality, which is being highlighted through scientific presentations and our recent Nature Biotechnology publication. Alpha-1 antitrypsin deficiency (AATD) is uniquely suited for an RNA editing therapeutic, and our AATD program is rapidly advancing towards clinical development with IND enabling studies on track to initiate in the third quarter of this year.”
Recent Pipeline and Business Highlights
Announced first clinical data from ongoing FOCUS-C9 trial of WVE-004 for C9-ALS and C9-FTD demonstrating potent and durable target engagement with low, single doses
In April 2022, Wave announced a positive update to its ongoing FOCUS-C9 trial of WVE-004 (stereopure, PN-modified silencing oligonucleotide) for C9orf72-associated amyotrophic lateral sclerosis (C9-ALS) and frontotemporal dementia (C9-FTD). The update was driven by the observation of potent and durable reductions of poly(GP) dipeptide repeat proteins in cerebrospinal fluid (CSF), a C9-ALS/C9-FTD disease biomarker that, when reduced in CSF, indicates WVE-004’s engagement of target in the brain and spinal cord. Based on the poly(GP) reduction data, the observation period for single dose cohorts is being extended and additional patients are being enrolled into the trial to further characterize depth of knockdown, durability and longer-term safety profile. Wave plans to share this recently announced clinical data in an oral presentation at the upcoming European Network to Cure ALS (ENCALS) Meeting in Edinburgh, Scotland, which is taking place June 1 – 3, 2022.
FOCUS-C9 (NCT04931862) is an adaptive trial that was 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). Planning is underway to initiate an open-label extension (OLE) clinical trial in mid-2022.
Continued to advance clinical trials evaluating WVE-003 targeting SNP3 for Huntington’s disease (HD) and WVE-N531 for Duchenne muscular dystrophy (DMD) amenable to exon 53 skipping
WVE-003 for HD (PN-modified silencing oligonucleotide) is being evaluated in the ongoing, adaptive, double-blind Phase 1b/2a SELECT-HD (NCT05032196) clinical trial. WVE-003 is designed to selectively target the mutant allele of the huntingtin (mHTT) gene, while leaving the wild-type (healthy) HTT (wtHTT) protein relatively intact.
WVE-N531 for DMD (PN-modified splicing oligonucleotide) is being evaluated in an open-label, intra-patient dose escalation (NCT04906460) clinical trial. Dose escalation is ongoing and being guided by tolerability and plasma PK, with possible cohort expansion informed by an assessment of drug distribution in muscle and biomarkers, including dystrophin, following multiple doses of WVE-N531.
Presented preclinical AIMer data for AATD program supporting the potential for a novel, first-in-class, subcutaneous therapeutic to address both lung and liver manifestations of disease
In March 2022, preclinical data for Wave’s Alpha-1 antitrypsin deficiency (AATD) AIMer program demonstrating restoration of functional AAT protein and reduction of liver aggregates in a transgenic mouse model was shared in a Featured Session at the 7th Annual Oligonucleotide & Precision Therapeutics (OPT) Congress. At 19 weeks, GalNAc-conjugated SERPINA1 AIMers resulted in approximately 60% RNA editing of SERPINA1 transcript and circulating serum AAT levels (18.5 uM) in AIMer administered mice that were approximately 5-fold greater than PBS-administered controls.
Today, May 12, 2022, at the TIDES USA: Oligonucleotide & Peptide Therapeutics Conference, Wave is presenting additional preclinical data that confirmed restored AAT protein in serum was functional at week 19, as measured by a 3-fold increase in neutrophil elastase inhibition over placebo control. A histological analysis indicated reduction of liver aggregates in a transgenic mouse model at 19 weeks with AIMers. Wave will also share these data in an oral presentation at the American Society of Gene and Cell Therapy (ASGCT) 25th Annual Meeting taking place May 16 – 19, 2022 in Washington, D.C.
Scientific publications highlight breadth and potential of Wave’s therapeutic oligonucleotide platform, including novel PN-chemistry and RNA editing modality
In March 2022, preclinical proof-of-concept data for Wave’s novel ADAR-mediated RNA base editing modality was published in the journal Nature Biotechnology – the first scientific publication to report that RNA base editing in NHPs can be achieved with a simplified oligonucleotide approach. Data reported include an in vivo study where Wave’s GalNAc-conjugated A-to-I(G) RNA base editing oligonucleotides (“AIMers”) yielded up to 50% editing of ACTB (Beta-actin) transcript in the liver of non-human primates (NHPs), with editing levels persisting as high as 40% for more than one month.
In February 2022, two papers were published in the journal Nucleic Acids Research (NAR) that reported a multitude of preclinical in vitro and in vivo studies demonstrating the incorporation of PN backbone chemistry modifications (PN chemistry) in stereopure silencing oligonucleotides (publication link) and stereopure splicing oligonucleotides (publication link) significantly improves potency, distribution, and durability of effect.
Wave has published a total of eight peer-reviewed papers thus far in 2022.
Key Anticipated 2022 Milestones
WVE-004 for C9-ALS and C9-FTD:
Additional single and multidose clinical data for WVE-004 expected throughout 2022. Wave expects to use these data to optimize WVE-004 dose level and frequency, as well as to enable discussions with regulatory authorities regarding the next phase of development later in 2022.
Planning underway to initiate an open-label extension (OLE) clinical trial in mid-2022.
WVE-003 for HD:
Clinical data expected in 2022 for WVE-003 to provide further insight into the clinical effects of PN chemistry and enable decision-making for this program.
WVE-N531 for DMD:
Clinical data, including muscle biopsies, expected in 2022 for WVE-N531 to provide further insight into the clinical effects of PN chemistry and enable decision-making for this program.
AIMer GalNAc-conjugated program for AATD:
Wave expects to select an AATD AIMer development candidate and initiate IND-enabling toxicology studies in the third quarter of 2022.
First Quarter 2022 Financial Results and Financial Guidance
Wave reported a net loss of $37.8 million in the first quarter of 2022, as compared to $42.5 million in the same period in 2021.
Wave recorded revenue of $1.8 million for the first quarter of 2022, primarily under the Takeda Collaboration. Wave did not record any revenue under the Takeda Collaboration in the first quarter of 2021.
Research and development expenses were $27.5 million in the first quarter of 2022 as compared to $33.4 million in the same period in 2021. The decrease in research and development expenses in the first quarter was primarily due to decreased external expenses related to our previously disclosed discontinued PRECISION-HD programs, partially offset by increased internal and external expenses related to PRISM, including ADAR editing, and other ongoing programs.
General and administrative expenses were $12.4 million in the first quarter of 2022 as compared to $10.1 million in the same period in 2021. The increase in general and administrative expenses in the first quarter of 2022 was primarily due to increases in compensation-related expenses, as well as increases in professional services expenses and other general and administrative operating expenses.
As of March 31, 2022, Wave had $111.7 million in cash, cash equivalents and short-term investments. As of December 31, 2021, Wave had $150.6 million in cash and cash equivalents. This decrease was mainly due to Wave’s year-to-date net loss of $37.8 million.
Wave expects that its existing cash, cash equivalents and short-term investments will enable the company to fund its operating and capital expenditure requirements into the second quarter of 2023.

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.
About Amyotrophic Lateral Sclerosis and Frontotemporal Dementia
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease in which the progressive degeneration of motor neurons in the brain and spinal cord leads to the inability to initiate or control muscle movement. People with ALS may lose the ability to speak, eat, move and breathe. ALS affects as many as 20,000 people in the United States.
Frontotemporal dementia (FTD) is a fatal neurodegenerative disease in which progressive nerve cell loss in the brain's frontal lobes and temporal lobes leads to personality and behavioral changes, as well as the gradual impairment of language skills. It is the second most common form of early-onset dementia after Alzheimer’s disease in people under the age of 65. FTD affects as many as 70,000 people in the United States.
A hexanucleotide repeat expansion (G4C2) is the most common known genetic cause of the sporadic and inherited forms of ALS and FTD. The expansion leads to production of modified sense and antisense transcripts that can form nuclear RNA foci and encode dipeptide protein repeats (DPRs), which are believed to drive disease pathology. Additionally, the G4C2 expansion can decrease expression of C9orf72 protein, affecting regulation of neuronal function and the immune system.
In the United States, mutations of the C9orf72 gene are present in approximately 40% of familial ALS cases and ~8-10% of sporadic ALS cases. In FTD, the mutations appear in 38% of familial cases and 6% of sporadic cases.
About Huntington’s Disease
Huntington’s disease (HD) is a debilitating and ultimately fatal autosomal dominant neurological disorder, characterized by cognitive decline, psychiatric illness, and chorea. HD causes nerve cells in the brain to deteriorate over time, affecting thinking ability, emotions, and movement. HD is caused by an expanded cytosine-adenine-guanine (CAG) triplet repeat in the huntingtin (HTT) gene that results in production of mutant HTT (mHTT) protein. Accumulation of mHTT causes progressive loss of neurons in the brain. Wild-type, or healthy, HTT (wtHTT) protein is critical for neuronal function and suppression may have detrimental long-term consequences. Approximately 30,000 people in the United States have symptomatic HD and more than 200,000 others are at risk for developing the disease. There are currently no approved disease-modifying therapies available.
About Duchenne Muscular Dystrophy
Duchenne muscular dystrophy (DMD) is a fatal X-linked genetic neuromuscular disorder caused predominantly by out-of-frame deletions in the dystrophin gene, resulting in absent or defective dystrophin protein. Dystrophin protein is needed for normal muscle maintenance and operation. Because of the genetic mutations in DMD, the body cannot produce functional dystrophin, which results in progressive and irreversible loss of muscle function, including the heart and lungs. Worldwide, DMD affects approximately one in 5,000 newborn boys. Approximately 8%-10% of DMD patients have mutations amenable to treatment with an exon 53 skipping therapy. Exon skipping aims to address the underlying cause of DMD by promoting the production of dystrophin protein to stabilize or slow disease progression.
