(NASDAQ: GPCR), a clinical-stage global biopharmaceutical company developing novel oral small molecule therapeutics for metabolic and cardiopulmonary diseases, today reported financial results for the fourth quarter and full year ended December 31, 2023, and highlighted recent corporate achievements. “In 2023 we demonstrated clear proof-of-concept with our lead GLP-1 receptor agonist, GSBR-1290, for obesity and type 2 diabetes. As a differentiated oral small molecule we have the scalability and manufacturing advantages to potentially meet the significant unmet need currently observed in the GLP-1 space,” said Raymond Stevens, Ph.D., Founder and CEO of Structure Therapeutics. “With a year-end cash balance of $467.3 million providing runway through the end of 2026, we are well-positioned to initiate and complete our Phase 2b trials for GSBR-1290 and accelerate development of our oral small molecule programs targeting amylin, GIP, and apelin receptors.” Recent Highlights and Upcoming Milestones GSBR-1290 for Type 2 Diabetes Mellitus (T2DM) and Obesity In December 2023, the Company reported clinically meaningful data from the Phase 2a study in T2DM demonstrating significant reductions in hemoglobin A1c (HbA1c) and weight at 12 weeks. Interim Phase 2a data from the obesity cohort demonstrated significant reduction in weight at 8 weeks. Across both cohorts, GSBR-1290 was generally well-tolerated with no treatment-related serious adverse events over 12 weeks and low study discontinuation rates due to adverse events related to study drug (2.8% in T2DM and 0% in obesity).Topline data from the obesity cohort of the Phase 2a study, including full 12-week efficacy data for 40 participants and safety and tolerability for all 64 participants. This study is fully enrolled and data are expected in the latter half of the second quarter of 2024.In preparation for later stage clinical trials, a formulation bridging and titration optimization study to evaluate capsule versus tablet pharmacokinetics (PK) and explore different titration regimens of GSBR-1290 is ongoing. This study is fully enrolled and data are expected in the latter half of the second quarter of 2024.The Company plans to initiate a global Phase 2b obesity study of GSBR-1290 in the fourth quarter of 2024.The Company plans to initiate a Phase 2 study in T2DM in the second half of 2024. GLP-1R Combination Programs: Amylin, GIPR, Apelin (APJR) Oral Small Molecule Amylin Program: The Company is developing amylin agonists for use either alone or in combination with GLP-1R agonists to treat obesity and associated diseases, and expects to select a development candidate in the second half of 2024.Oral Small Molecule GIPR Program: The Company is developing a GIPR selective agonist and GLP‑1R/GIPR combinations to treat obesity and associated diseases, and expects to select a development candidate in the first half of 2025.Oral Small Molecule Apelin Receptor (APJR) Program: The Company is evaluating its Phase 2 ready ANPA-0073, a biased agonist targeting APJR used in combination with weight loss medicines, for selective or muscle-sparing weight loss. ANPA-0073 is also being evaluated for idiopathic pulmonary fibrosis (IPF). The Company has completed a Phase 1 single-ascending and multiple-ascending dose study, in which ANPA-0073 was generally well-tolerated with no serious adverse event reported. LPA1R Program for Idiopathic Pulmonary Fibrosis (IPF) The Company is developing LTSE-2578, an oral small molecule antagonist that targets lysophosphatidic acid 1 receptor (LPA1R).

Study Achieves Primary and all Secondary Endpoints, Demonstrating Statistically Significant Reductions in Body Weight at all Doses as Compared to Placebo Up to 13.1% Placebo-Adjusted Mean Weight Loss (14.7% From Baseline) Observed After 13 Weeks of Treatment; No Plateau Observed VK2735 Shown to be Safe and Well-Tolerated in 13-Week Study; 95% of GI-specific Treatment Emergent Adverse Events Considered Mild or Moderate Conference Call Scheduled for 8:00 a.m. ET Today SAN DIEGO, Feb. 27, 2024 /PRNewswire/ -- Viking Therapeutics, Inc. ("Viking") (NASDAQ: VKTX), a clinical-stage biopharmaceutical company focused on the development of novel therapies for metabolic and endocrine disorders, today announced positive top-line results from the company's Phase 2 clinical trial of VK2735, a dual agonist of the glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors in development for the potential treatment of various metabolic disorders such as obesity. The Phase 2 VENTURE trial successfully achieved its primary endpoint and all secondary endpoints, with patients receiving VK2735 demonstrating statistically significant reductions in body weight compared with placebo. Additionally, the study showed VK2735 treatment to be safe and well tolerated with the majority of treatment emergent adverse events (TEAEs) being categorized as mild or moderate. Based on these findings, Viking intends to meet with the FDA and discuss next steps in the development of VK2735. Top-line study results include: Body Weight Reductions Patients receiving weekly doses of VK2735 demonstrated statistically significant reductions in mean body weight after 13 weeks, ranging up to 14.7% from baseline. Patients receiving VK2735 also demonstrated statistically significant reductions in mean body weight relative to placebo, ranging up to 13.1%. Statistically significant differences compared to both baseline and placebo were observed for all doses starting at Week one and continuing throughout the 13-week treatment period. Reductions in body weight were progressive through the course of the study, with no plateau observed for weight loss at 13 weeks. All doses of VK2735 also demonstrated statistically significant differences relative to placebo on the key secondary endpoint assessing the proportion of patients demonstrating at least 10% weight loss. Up to 88% of patients in VK2735 treatment groups achieved ≥10% weight loss, compared with 4% for placebo. Observed Change in Body Weight Following 13 Weeks of Once-Weekly Dosing with VK2735 Safety and Tolerability VK2735 demonstrated encouraging safety and tolerability following 13 weeks of once-weekly dosing. Discontinuation rates in the VENTURE study were low and well-balanced among patients treated with VK2735 compared with placebo. A total of 23 patients (13%) discontinued treatment in the study, 5 (14%) in the placebo cohort and 18 (13%) among VK2735-treated cohorts. Among patients receiving VK2735, the majority (92%) reported drug related TEAEs as mild or moderate in severity. The majority of TEAEs that were gastrointestinal (GI) in nature (95%) were also reported as mild or moderate. Nausea was reported among patients receiving both VK2735 (43%) and placebo (20%). Among subjects receiving VK2735, the majority of reported nausea (68%) was characterized as mild (32% moderate, none severe). Vomiting was reported in 25/140 (18%) VK2735-treated patients compared with none reported among patients receiving placebo. GI-related adverse events were generally observed early in treatment, with decreasing frequency upon repeat dosing. Across the combined VENTURE study arms, the weekly rate of nausea did not exceed 5% at any point after the first week of treatment. One patient receiving VK2735 experienced a serious adverse event (SAE) of dehydration that was characterized as related to study drug. Discontinuation Rates and Common Gastrointestinal TEAEs Following 13 Weeks of Once-Weekly Dosing with VK2735 "We are excited to report the top-line results from this important Phase 2 study. VK2735 continues to demonstrate a promising efficacy and tolerability pro 13 weeks of repeat dosing in obese subjects," said Brian Lian, Ph.D., chief executive officer of Viking. "Notably, robust weight loss compared with placebo was observed early across all doses evaluated in the VENTURE study, and continued throughout the treatment period in all treatment groups. No evidence of a plateau was observed at Week 13 for any VK2735 dose, suggesting further weight loss might be achieved from extended dosing periods. We look forward to progressing this important therapy into further clinical development later this year. Separately, we remain on track to report data from a Phase 1 study of an oral formulation of VK2735 later this quarter." The Phase 2 VENTURE trial was a randomized, double-blind, placebo-controlled study intended to evaluate the safety, tolerability, pharmacokinetics, and weight loss efficacy of VK2735, administered subcutaneously, once weekly. The 13-week trial enrolled 176 adults who are obese (BMI ≥30 kg/m2), or adults who are overweight (BMI ≥27 kg/m2) with at least one weight-related comorbid condition. The primary endpoint of the study was the assessment of the percent change in body weight from baseline to Week 13 among patients treated with VK2735 as compared with placebo, while secondary and exploratory endpoints evaluated a range of additional safety and efficacy measures.

Conference call scheduled for 4:30 p.m. ET today Results for Phase 2 VENTURE Trial of GLP-1/GIP Agonist VK2735 in Obesity Expected in 1Q24 Histology Results for Phase 2b VOYAGE Study Evaluating VK2809 for the Treatment of NASH and Fibrosis Expected in 1H24 Results for Phase 1 Trial of Oral VK2735 Expected in 1Q24 Strong Year-End Cash Position of $362 Million SAN DIEGO, Feb. 7, 2024 /PRNewswire/ -- Viking Therapeutics, Inc. ("Viking") (NASDAQ: VKTX), a clinical-stage biopharmaceutical company focused on the development of novel therapies for metabolic and endocrine disorders, today announced its financial results for the fourth quarter and year ended December 31, 2023, and provided an update on its clinical pipeline and other corporate developments. Highlights from the Quarter Ended December 31, 2023, and Other Recent Events: "2023 was an event-filled year for Viking, with the company achieving significant progress with each of our four clinical programs," stated Brian Lian, Ph.D., chief executive officer of Viking. "In the first quarter, we reported results from the first Phase 1 trial of VK2735, our newest clinical program, for the treatment of obesity. This study demonstrated early signals of efficacy, as well as promising safety and tolerability. Last fall, we initiated the VENTURE Phase 2 trial to evaluate VK2735's longer term clinical benefits and completed enrollment in an upsized trial more rapidly than expected. In 2023 we also initiated a complementary Phase 1 clinical trial evaluating a novel oral formulation of VK2735, which we believe may expand the market opportunity for this therapeutic. We expect to report topline results from both the VENTURE Phase 2 study and the Phase 1 trial of oral VK2735 in the first quarter of 2024. An additional highlight for 2023 was the announcement of positive topline results from our Phase 2b VOYAGE study of VK2809 in patients with biopsy-confirmed non-alcoholic steatohepatitis with fibrosis. This study affirmed VK2809's best-in-class profile, demonstrating statistically significant liver-fat reduction, unique lipid-lowering properties, and favorable safety and tolerability profile. We look forward to reporting the 52-week biopsy data from this study in the first half of 2024. Importantly, we completed 2023 with a strong cash position that will support our objectives for 2024 and beyond. We look forward to an exciting year ahead and thank our shareholders and partners, as well as the investigators and patients participating in our clinical programs, for their continued support." Pipeline and Recent Corporate Highlights Results for Phase 2 VENTURE Trial of GLP-1/GIP Agonist VK2735 in Obesity Expected in 1Q24. VK2735 is a wholly owned dual agonist of the glucagon like peptide-1, or GLP-1 receptor, and the glucose dependent insulinotropic polypeptide, or GIP receptor, for the potential treatment of various metabolic disorders such as obesity, non-alcoholic steatohepatitis (NASH), and certain rare disorders. During the first quarter of 2023, Viking announced positive results from a Phase 1 single ascending dose (SAD) and multiple ascending dose (MAD) clinical trial of VK2735 following 28 days of weekly dosing in healthy volunteers. In the MAD portion of the study, VK2735 demonstrated encouraging safety and tolerability, and positive signs of clinical activity. All cohorts receiving VK2735 experienced reductions in mean body weight from baseline, ranging up to 7.8%. Cohorts receiving VK2735 also demonstrated reductions in mean body weight relative to placebo, ranging up to 6.0%. Statistically significant differences compared to placebo were maintained or improved at the Day 43 follow-up time point, 21 days after the last dose of VK2735 was administered. VK2735 also demonstrated encouraging safety and tolerability following repeated dosing. The majority of observed adverse events (98%) were reported as mild or moderate, and the majority of gastrointestinal-related adverse events (99%) were also reported as mild or moderate. This study also demonstrated VK2735's encouraging impact on liver fat and plasma lipids. Specifically, after four weekly subcutaneous doses of VK2735, subjects in the Phase 1 trial reported liver fat reductions of up to 47% from baseline. Among subjects with non-alcoholic fatty liver disease, placebo-adjusted reductions in liver fat reached approximately 59%. Though the sample size was limited, these results indicate VK2735's potential benefit in patients with various forms of fatty liver disease. With respect to plasma lipids, treatment with VK2735 produced encouraging reductions from baseline in total cholesterol of up to 21%, and reductions in LDL-cholesterol of up to 23%. In addition, plasma levels of apolipoprotein B were reduced by up to 21%. These findings are particularly interesting in light of the fact that these healthy volunteers began the study with normal baseline lipid levels. The results from this trial were featured in an oral presentation at ObesityWeek® in October 2023. During the third quarter of 2023, Viking initiated the Phase 2 VENTURE trial, evaluating VK2735 in patients with obesity. The VENTURE trial is a randomized, double-blind, placebo-controlled multicenter study to evaluate the safety, tolerability, pharmacokinetics, and weight loss efficacy of VK2735, administered subcutaneously, once weekly for 13 weeks. The trial was designed to enroll adults who are obese (BMI ≥30 kg/m2) or adults who are overweight (BMI ≥27 kg/m2) with at least one weight-related comorbid condition. Due to heightened clinician and patient interest, the trial size was increased to 176 patients, compared with the original target of 125 patients. The primary endpoint of the study will assess the percent change in body weight from baseline to Week 13 among patients treated with VK2735 as compared with placebo, with secondary and exploratory endpoints evaluating a range of additional safety and efficacy measures. The doses being evaluated range from 2.5 mg to 15 mg, compared to the 10 mg top dose evaluated in the prior Phase 1 MAD study. The company completed enrollment in VENTURE in 4Q23 and expects to report topline results from this study in 1Q24. Results for Phase 1 Trial of Oral VK2735 Expected in 1Q24. Concurrent with the 1Q23 announcement of results from the Phase 1 trial of the injectable formulation of VK2735, Viking announced the initiation of a Phase 1 clinical study to evaluate a novel oral formulation of VK2735. Viking believes the potential to provide both subcutaneous and oral dosage forms may represent an important option for patients, and may significantly expand the market opportunity for VK2735. This study is an extension of the SAD/MAD Phase 1 trial described above, and is a randomized, double-blind, placebo-controlled trial in healthy adults with a minimum BMI of 30 kg/m2. The primary objective of the study is to evaluate the safety and tolerability of VK2735 administered as an oral tablet once daily for 28 days. The secondary objective is to evaluate the pharmacokinetics of orally administered VK2735 in healthy subjects. Exploratory pharmacodynamic measures include assessments of changes in body weight and other metrics. The company expects to report the initial data from the oral formulation Phase 1 study in 1Q24. Histology Results for Phase 2b VOYAGE Study Evaluating VK2809 for the Treatment of NASH and Fibrosis Expected in 1H24. VK2809 is an orally available, small molecule agonist of the thyroid hormone receptor that is selective for liver tissue, as well as the beta isoform of the receptor. Viking is currently evaluating VK2809 in the Phase 2b VOYAGE study, in patients with biopsy-confirmed NASH and fibrosis. The VOYAGE study is a randomized, double-blind, placebo-controlled, multicenter, international trial designed to assess the efficacy, safety and tolerability of VK2809 in patients with biopsy-confirmed NASH and fibrosis. Enrollment included patients with at least 8% liver fat content as measured by magnetic resonance imaging, proton density fat fraction (MRI-PDFF), as well as F2 and F3 fibrosis. The study also allowed for up to 25% of enrolled patients to have F1 fibrosis, provided that they possess at least one additional risk factor, such as diabetes, obesity or hypertension. The primary endpoint of the study evaluated the change in liver fat content from baseline to Week 12 in patients treated with VK2809 as compared to patients receiving placebo. Secondary objectives include the evaluation of histologic changes assessed by hepatic biopsy after 52 weeks of treatment. During the second quarter of 2023, Viking announced positive topline results from the VOYAGE study. The trial successfully achieved its primary endpoint, with patients receiving VK2809 experiencing statistically significant reductions in liver fat content from baseline to Week 12 as compared with placebo. The median relative change from baseline in liver fat as assessed by MRI-PDFF ranged from 38% to 55% for patients receiving VK2809. Importantly, up to 85% of patients receiving VK2809 experienced at least a 30% relative reduction in liver fat content (p<0.0001), a level of reduction that is associated with greater likelihood of histologic improvement in NASH. Additionally, VK2809-treated patients demonstrated statistically significant reductions in LDL-cholesterol, triglycerides, and atherogenic lipoproteins, all of which have been correlated with cardiovascular risk. These results support prior data demonstrating that VK2809 may offer a cardio-protective benefit through its robust reduction in plasma lipids. The results for the primary endpoint of the VOYAGE Phase 2b study were highlighted in a November presentation at the annual meeting of the American Association for the Study of Liver Diseases (AASLD). A key takeaway from the presentation was the finding that treatment with VK2809 led to robust and comparable liver fat reductions among patients with or without type 2 diabetes, as well as in patients with either F2 or F3 fibrosis. Specifically, among patients with type 2 diabetes, reductions from baseline in liver fat were reported for all VK2809 cohorts, ranging from 36% to 54% at Week 12. This effect size was comparable to that reported for patients without type 2 diabetes. Among non-diabetics, reductions in liver fat from baseline ranged from 19% to 51%. These data suggest that activation of the thyroid hormone beta receptor remains effective at reducing liver fat in the presence of an important metabolic comorbidity commonly observed in patients with NASH. Consistent efficacy was also observed in patients with F2 or F3 fibrosis. Thus, it appears that neither the presence of type 2 diabetes nor the presence of F2 or F3 fibrosis meaningfully impacts VK2809's efficacy at reducing liver fat. As steatosis and lipotoxicity are believed to be underlying drivers in NASH, these data suggest benefits across important disease subgroups. The topline VOYAGE data also confirmed previously reported results demonstrating VK2809's encouraging safety and tolerability profile. After 12 weeks, 94% of treatment-related adverse events among patients receiving VK2809 were reported as mild or moderate. In particular, as observed in prior studies, VK2809 demonstrated excellent GI tolerability, with rates of nausea, diarrhea, stool frequency, and vomiting similar among VK2809-treated patients compared to placebo. The company expects to report data from the secondary and exploratory objectives of the VOYAGE study, including the evaluation of histologic changes assessed by hepatic biopsy after 52 weeks of treatment, in the first half of 2024. Results for Phase 1b Study of VK0214 in X-ALD Expected in 1H24. VK0214 is a novel, orally available thyroid hormone receptor beta agonist that is being evaluated as a potential treatment for X-linked adrenoleukodystrophy (X-ALD), a rare neurogenerative disease for which there are currently no pharmacologic treatment options. Results from a prior Phase 1 study of VK0214 in healthy volunteers successfully achieved its primary and secondary endpoints, demonstrating encouraging safety and tolerability, dose-dependent exposures, no evidence of accumulation, and a half-life consistent with once-daily dosing. No serious adverse events were observed, and no differences were reported for GI side effects such as nausea or diarrhea among subjects treated with VK0214 compared with placebo. Following completion of the Phase 1 study, Viking initiated a Phase 1b study of VK0214 in patients with the adrenomyeloneuropathy, or AMN, form of X-ALD, which is the most common form of the disorder. The Phase 1b trial is a randomized, double-blind, placebo-controlled multi-center study in adult male patients with AMN. The primary objectives of the study are to evaluate the safety and tolerability of VK0214 administered orally, once daily for 28 days. The study also includes an evaluation of the pharmacokinetics of VK0214 in AMN patients, as well as an exploratory assessment of changes in plasma levels of very long chain fatty acids. The company expects to announce results from the Phase 1b study of VK0214 in adrenomyeloneuropathy in 1H24. Strong Year-End Cash Position of $362 Million.
