WVE-007 (INHBE GalNAc-siRNA for obesity) is on track to initiate a clinical trial in 1Q 2025; new preclinical data for WVE-007 demonstrate opportunities for monotherapy, for synergistic use with GLP-1s, and for maintenance to avoid rebound weight gain following cessation of GLP-1s Recent proof-of-mechanism data for WVE-006 unlocked Wave’s best-in-class RNA editing capabilities; three new wholly owned RNA editing programs targeting PNPLA3, LDLR and APOB are first-in-class approaches to address significant unmet needs in cardiometabolic diseases Wave plans to have five GalNAc-RNA editing or GalNAc-siRNA programs in the clinic by 2026 Wave’s clinically validated platform continues to lead on the improvement of intracellular delivery using novel chemistry, including PN backbone chemistry modifications CAMBRIDGE, Mass., Oct. 30, 2024 (GLOBE NEWSWIRE) -- Wave Life Sciences Ltd. (Nasdaq: WVE), a clinical-stage biotechnology company focused on unlocking the broad potential of RNA medicines to transform human health, today announced updates across its growing pipeline, which were also discussed during the company’s virtual analyst and investor Research Day (link to webcast). Updates included new preclinical data for Wave’s GalNAc-small interfering RNA (siRNA) approach for obesity, WVE-007, which is on track to initiate a clinical trial in the first quarter of 2025. Wave also introduced new, wholly owned GalNAc-RNA editing programs and demonstrated its leadership in oligonucleotide chemistry innovation. “This year, we showed through multiple positive clinical datasets that our leading RNA medicines platform is opening up new possibilities for the treatment of human disease. Next to the clinic will be our WVE-007 program, which reimagines obesity treatment with a mechanism that directly impacts fat cells – particularly visceral fat – and which could be used as monotherapy, add-on to GLP-1s, or for maintenance post-GLP-1 cessation,” said Paul Bolno, MD, MBA, President and Chief Executive Officer at Wave Life Sciences. “Additionally, we are excited to introduce three new programs for mRNA correction and upregulation to treat cardiometabolic diseases with significant unmet needs. These programs have substantial, well-defined patient populations, strong support from human genetics, efficient paths to proof-of-concept in the clinic, and offer the opportunity to meaningfully change health outcomes for millions of people. This truly is an exciting time for Wave and for patients as we unlock new biology and build our high-value and innovative pipeline.” Key Highlights from Today’s Virtual Research Day WVE-007: INHBE GalNAc-siRNA and potential best-in-class obesity therapeutic approaching the clinic WVE-007 is Wave’s GalNAc-siRNA that targets INHBE as a novel approach to treat obesity. The approach is based on human genetics, where individuals who have a protective loss-of-function mutation in the INHBE gene have a healthier cardiometabolic profile, including less unhealthy visceral fat, lower triglycerides, and lower risk of type 2 diabetes and cardiovascular disease.Silencing of INHBE in vivo directly impacts adipocytes (fat cells) and induces lipolysis (fat burning), which is different from GLP-1s’ centrally acting mechanism that involves the digestive system and central nervous system to decrease appetite.New preclinical data in diet induced obese (DIO) mice demonstrate the potential of WVE-007 to be used across the treatment continuum, including as monotherapy, as an add-on to GLP-1s, and for maintenance to prevent weight regain and weight cycling after discontinuing GLP-1s.Wave is on track to initiate a Phase 1 clinical trial for WVE-007 in adults living with overweight or obesity in the first quarter of 2025. The trial is planned to assess safety, tolerability, pharmacokinetics, and Activin E lowering (a biomarker for target engagement), as well as body composition. New GalNAc-RNA editing programs designed to optimally address high-impact cardiometabolic diseases Building on Wave’s recent achievement of the first-ever therapeutic RNA editing with WVE-006 in alpha-1 antitrypsin deficiency, the company today announced three new, wholly owned RNA editing programs that are on track for candidate selection in 2025. Like WVE-006, these programs leverage GalNAc conjugation and have efficient clinical paths to proof-of-concept. These new programs include: PNPLA3 (mRNA correction): Homozygous PNPLA3-I148M patients are at high risk for a variety of liver diseases and there are more than 9 million impacted individuals in the US and Europe. Wave’s RNA editing approach aims to achieve at least 50% correction to restore the heterozygous phenotype with low risk of liver disease, similar to the approach with WVE-006.LDLR (mRNA upregulation) and APOB (mRNA correction): High unmet needs remain among familial hypercholesterolemia (FH) patients, with approximately half of patients not reaching goal LDL-c levels with available therapies. Wave’s AIMers to upregulate LDLR and correct APOB have potential to be first-in-class treatment approaches for best-in-class effects to reach target LDL-c levels in Heterozygous FH (HeFH) patients. Combined, LDLR and APOB AIMers would address ~1 million HeFH patients in the US and Europe. LDLR upregulation also offers significant expansion opportunities in patients with statin intolerance or prior cardiovascular events (~30 million patients in the US and Europe). Chemistry innovation enhancing intracellular delivery Today, Wave shared data demonstrating how its proprietary chemistry results in marked improvements in five key areas of intracellular delivery: 1) cellular uptake; 2) endosomal release; 3) cellular residency; 4) nuclear uptake; and 5) target engagement.Wave shared how it is using PN variants and modifications to physicochemical properties to achieve best-in-class siRNA silencing and RNA editing in a variety of extrahepatic tissues.Wave also highlighted novel chemistry used in its AIMers, including proprietary N-3-uridine chemistry (N3U), which substantially enhances RNA editing efficiency. This novel chemistry was the subject of a recent Nucleic Acids Research publication.

Evidence demonstrates that SUBLOCADE supports long-term recovery from opioid use disorder (OUD) and is effective and safe. Publications highlight the importance of overcoming access barriers to long-acting injectable treatments for OUD RICHMOND, Va., Oct. 30, 2024 /PRNewswire/ -- Indivior PLC (Nasdaq/LSE: INDV), in recognizing Substance Abuse Prevention Month, provides an update on key findings from the last year that demonstrate the importance of access to medications for the treatment of opioid use disorder (MOUD) and the effectiveness and safety of SUBLOCADE® in the treatment of OUD. These data add to the growing body of evidence that SUBLOCADE can improve outcomes, such as abstinence, retention, and recovery in persons with OUD. Publications In a post hoc analysis of the SUBLOCADE randomized, double-blind, placebo-controlled phase 3 clinical trial, published in Harm Reduction Journal, SUBLOCADE 300 mg maintenance dose resulted in a statistically significant increase in abstinence from opioids among study participants with OUD who injected opioids compared to 100 mg maintenance dose. However, both were equally effective in non-injecting participants. Results from the Community Long-Acting Buprenorphine (CoLAB) Study, a prospective single-arm, multicenter, open label trial in Australia, were published in the International Journal of Drug Policy, and demonstrated that participants could be maintained on SUBLOCADE treatment for 96 weeks with continuous improvements in abstinence, depression, quality of life and medication satisfaction. In a qualitative research survey of 20 participants representing various practice settings, published in American Health & Drug Benefits, it was determined that telemedicine was the most common solution adopted during the COVID-19 pandemic to overcome access barriers. However, today there are still significant challenges in ensuring appropriate access to medications for those living with OUD and continued support, effective solutions and policies in the United States, need to be continually addressed. In a narrowly focused literature, policy, and legal proceedings review, published in Corrections Today, a clear disparity in access to MOUD was found between the general public and incarcerated individuals. Stigma and informed consent were the most discussed barriers used to justify policies limiting MOUD for incarcerated individuals.

Indivior is committed to continuing to advance the understanding of patients with OUD, educate on evidence-based practices, overcome stigma, and focus on recovery outcomes." Among the almost 6 million people aged 12 or older with a past year opioid use disorder in 2023, only 18% (or one million people) received treatment through MOUD.1 About SUBLOCADE® SUBLOCADE ® (buprenorphine extended-release) injection, for subcutaneous use, CIII INDICATION AND HIGHLIGHTED SAFETY INFORMATION INDICATION SUBLOCADE is indicated for the treatment of moderate to severe opioid use disorder in patients who have initiated treatment with a buprenorphine-containing product, followed by dose adjustment for a minimum of 7 days. SUBLOCADE should be used as part of a complete treatment plan that includes counseling and psychosocial support. HIGHLIGHTED SAFETY INFORMATION WARNING: RISK OF SERIOUS HARM OR DEATH WITH INTRAVENOUS ADMINISTRATION; SUBLOCADE RISK EVALUATION AND MITIGATION STRATEGY Serious harm or death could result if administered intravenously. SUBLOCADE forms a solid mass upon contact with body fluids and may cause occlusion, local tissue damage, and thrombo-embolic events, including life threatening pulmonary emboli, if administered intravenously. Because of the risk of serious harm or death that could result from intravenous self-administration, SUBLOCADE is only available through a restricted program called the SUBLOCADE REMS Program. Healthcare settings and pharmacies that order and dispense SUBLOCADE must be certified in this program and comply with the REMS requirements. CONTRAINDICATIONS SUBLOCADE should not be administered to patients who have been shown to be hypersensitive to buprenorphine or any component of Indivior's proprietary buprenorphine gel depot delivery system. WARNINGS AND PRECAUTIONS Addiction, Abuse, and Misuse: SUBLOCADE contains buprenorphine, a Schedule III controlled substance that can be abused in a manner similar to other opioids. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors. Respiratory Depression: Life threatening respiratory depression and death have occurred in association with buprenorphine. Warn patients of the potential danger of self-administration of benzodiazepines or other CNS depressants while under treatment with SUBLOCADE. Opioids can cause sleep-related breathing disorders e.g., central sleep apnea (CSA), sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. Consider decreasing the opioid using best practices for opioid taper if CSA occurs. Strongly consider prescribing naloxone at SUBLOCADE initiation or renewal because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose. Educate patients and caregivers on how to recognize respiratory depression and how to treat with naloxone if prescribed. Risk of Serious Injection Site Reactions: The most common injection site reactions are pain, erythema and pruritus with some involving abscess, ulceration, and necrosis. The likelihood of serious injection site reactions may increase with inadvertent intramuscular or intradermal administration. Neonatal Opioid Withdrawal Syndrome: Neonatal opioid withdrawal syndrome is an expected and treatable outcome of prolonged use of opioids during pregnancy. Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off the opioid. Risk of Opioid Withdrawal With Abrupt Discontinuation: If treatment with SUBLOCADE is discontinued, monitor patients for several months for withdrawal and treat appropriately. Risk of Hepatitis, Hepatic Events: Monitor liver function tests prior to and during treatment. Risk of Withdrawal in Patients Dependent on Full Agonist Opioids: Verify that patient is clinically stable on transmucosal buprenorphine before injecting SUBLOCADE. Treatment of Emergent Acute Pain: Treat pain with a non-opioid analgesic whenever possible. If opioid therapy is required, monitor patients closely because higher doses may be required for analgesic effect. ADVERSE REACTIONS Adverse reactions commonly associated with SUBLOCADE (in ≥5% of subjects) were constipation, headache, nausea, injection site pruritus, vomiting, increased hepatic enzymes, fatigue, and injection site pain.

iStock, NUniverse On its third-quarter earnings call Tuesday, Sage highlighted the launch of its Biogen-partnered postpartum depression drug Zurzuvae but said it will stop pursuing approval for major depressive disorder, which the FDA previously denied. Amid a season of setbacks, Sage Therapeutics reported strong third-quarter growth for its recently approved postpartum depression drug Zurzuvae, while announcing that it will no longer develop the therapy in major depressive disorder. In its Q3 earnings report released Tuesday afternoon, the company also noted a highly anticipated mid-stage readout in Huntington’s disease. Specifically, Sage reported $11 million in third-quarter revenue for Zurzuvae—50% of the net revenue reported by partner Biogen—representing 49% growth from the second quarter of 2024. The biotech’s cash position was slightly less favorable on September 30, 2024, than it was four months prior, with $569 million in cash, cash equivalents and marketable securities compared to $647 million on June 30. Sage was down 6.6% in premarket trading Wednesday, following the Q3 reveal. Sage and Biogen won approval for Zurzuvae in August 2023 as the first pill for postpartum depression (PPD), but the milestone was somewhat overshadowed by the FDA’s rejection of the drug in major depressive disorder (MDD) —a much larger market. On an investor call Tuesday, Sage CEO Barry Greene said Biogen and Sage would not pursue development of Zurzuvae in MDD in the U.S. “based on the significant new investment and time we expect would be needed to conduct the additional studies.” Greene added that Sage is “prioritizing our resources and supporting the PPD patient community.” Sage also announced it would discontinue Zulresso, an older PPD drug, as part of a strategic shift to more fully focus on the commercialization of Zurzuvae. Zulresso will be commercially available until Dec. 31, 2024. Sage executives on the call also highlighted an upcoming Phase II readout for dalzanemdor in Huntington’s disease patients with cognitive impairment. The readout follows a string of recent failures, as Sage reported earlier this month that dalzanemdor missed the primary endpoint in the Phase II LIGHTWAVE study in Alzheimer’s disease on the heels of another Phase II failure in Parkinson’s disease in April 2024. A Sage representative previously told BioSpace that Alzheimer’s and Huntington’s have differences in their underlying pathophysiology and symptomatology that can influence study outcomes. Sage Chief Medical Officer Laura Gault added that the Huntington’s disease patient population is “genetically defined” and younger than those seen in some of dalzanemdor’s previous studies. “That means this population is more homogeneous, has fewer medical comorbidities, and as a consequence, it’s easier to detect a signal in this population.” Sage executives also addressed the recently announced strategic reorganization , in which it will part with over 165 employees. Greene said Tuesday that the decision was intended to strengthen the company’s balance sheet, focus on the Zurzuvae launch and Huntington’s readout, and explore opportunities across its early-stage pipeline. “We believe that this restructuring will right-size Sage for future success,” Greene said.
