I encourage you to review all of the company's filings with the Securities and Exchange Commission, concerning these and other matters. I'll now turn the call over to Brian Lian for his initial comments.
Brian Lian: Thanks, Stephanie, and good afternoon to everyone dialed in by phone or listening on the webcast. Today, we'll review our financial results for the fourth quarter and full year ended December 31, 2023 and provide an update on recent progress with our clinical programs and operations. 2023 was an exciting year for Viking, highlighted by important data releases from two of our four clinical programs. With respect to our obesity program, during the year, we announced positive results from a first-in-human Phase 1 clinical trial of VK2735, a dual agonist of the GLP-1 and GIP receptors. In this study, subjects dosed with VK2735 demonstrated statistically significant weight loss with favorable safety and tolerability. Following these results, we initiated the Phase 2 trial called VENTURE to further evaluate VK2735 in patients with obesity.
We expect to report top line results from this study later this quarter. During the year, we also initiated a Phase 1 clinical trial, evaluating an oral formulation of VK2735. We expect to report results from this study later this quarter. Viking made good progress with other pipeline programs during the year as well. In May, we announced positive topline results from the Phase 2b VOYAGE study of our thyroid hormone receptor beta agonist, VK2809 in patients with biopsy-confirmed non-alcoholic steatohepatitis and fibrosis. This trial met its primary endpoint with patients receiving VK2809 demonstrating statistically significant reductions in liver fat as well as other important measures compared with patients treated with placebo. We look forward to reporting the 52-week biopsy data from this study in the first half of 2024.
On the financial side, we completed 2023 with a strong balance sheet, thanks to our continued diligence in managing expenses, along with a successful public offering of common stock, which resulted in gross proceeds of approximately $288 million. These funds will be used to support the continued advancement of our pipeline programs through multiple clinical milestones. I'll provide further details on our operations and development activities after we review our financial results for the fourth quarter and full year 2023. With that, I'll turn the call over to Greg Zante, Viking's Chief Financial Officer.
Greg Zante: Thanks, Brian. In conjunction with my comments, I'd like to recommend that participants refer to Viking's Form 10-K filing with the Securities and Exchange Commission, which we expect to file today. I'll now go over our results for the fourth quarter and full year ended December 31, 2023, beginning with the results for the quarter. Research and development expenses for the three months ended December 31, 2023, were $20.5 million compared to $16.2 million for the same period in 2022. The increase was primarily due to increased expenses related to clinical studies, pre-clinical studies, manufacturing for our drug candidates, stock-based compensation, salaries and benefits and third-party consultants. General and administrative expenses for the three months ended December 31, 2023, were $8.8 million compared to $4.1 million for the same period in 2022.
The increase was primarily due to increased expenses related to legal and patent services, stock-based compensation and third-party consultants, partially offset by decreased expenses related to salaries and benefits. For the three months ended December 31, 2023, Viking reported a net loss of $24.6 million, or $0.25 per share, compared to a net loss of $19.6 million, or $0.26 per share, in the corresponding period in 2022. The increase in net loss for the three months ended December 31, 2023, was primarily due to the increase in research and development expenses and general and administrative expenses noted previously, partially offset by increased interest income compared to the same period in 2022. I'll now go over the results for the 12 months ended December 31, 2023.
Our research and development expenses for the year ended December 31, 2023 were $63.8 million compared to $54.2 million for the same period in 2022. The increase was primarily due to increased expenses related to preclinical studies, stock-based compensation, manufacturing for our drug candidates, salaries and benefits and services provided by third-party consultants, partially offset by decreased expenses related to clinical studies. Our general and administrative expenses for the year ended December 31, 2023 were $37 million compared to $16.1 million for the same period in 2022. The increase was primarily due to increased expenses related to legal and patent services, stock-based compensation, third-party consultants and salaries and benefits.
For the year ended December 31, 2023, Viking reported a net loss of $85.9 million or $0.91 per share compared to a net loss of $68.9 million or $0.90 per share in the corresponding period in 2022. The increase in net loss for the year ended December 31, 2023 was primarily due to the increase in research and development expenses and general and administrative expenses noted previously, partially offset by increased interest income compared to the same period in 2022. Turning to the balance sheet. At December 31, 2023, Viking held cash, cash equivalents and short-term investments of $362 million compared to $155 million as of December 31, 2022. This concludes my financial review and I'll now turn the call back over to Brian.
Brian Lian: Thanks, Greg. As I mentioned in my opening comments, in 2023, Viking made significant progress with each of our 4 clinical programs, positioning the company for an exciting year ahead. I'll now briefly review our 2023 accomplishments and preview key objectives for 2024. I'll begin with an update on our VK2735 program for obesity. VK2735 is Viking's newest clinical stage compound and is a dual agonist of the glucagon-like peptide-1, or GLP-1 receptor and the glucose-dependent insulinotropic polypeptide, or GIP receptor. In the first quarter of 2023, we announced positive results from a Phase 1 single ascending dose and multiple ascending dose study of VK2735. This study was designed to evaluate the compound's initial safety, tolerability and pharmacokinetic profile, as well as its potential impact on exploratory metabolic measures, including body weight and liver fat.
The single ascending dose portion of the study enrolled healthy men and women and demonstrated that, single subcutaneous doses of VK2735 were safe and well tolerated and displayed favorable pharmacokinetics. VK2735 demonstrated a half-life of approximately 170 hours to 250 hours and excellent therapeutic exposures. The multiple ascending dose portion of this study enrolled healthy men and women with a minimum body mass index of 30 kilograms per meter squared. These subjects received subcutaneous doses of VK2735 once weekly for 28 days. As in the single ascending dose date, the multiple ascending dose study demonstrated encouraging safety and tolerability and positive signs of clinical activity. All cohorts receiving VK2735 demonstrated reductions in mean body weight from baseline ranging up to 7.8%.
Cohorts receiving VK2735 also demonstrated reductions in body weight relative to placebo, ranging up to 6%. Statistically significant differences in body weight compared to placebo were also maintained or improved at the day 43 follow-up time point, 21 days after the last dose of VK2735 was administered. With respect to safety and tolerability, 98% of observed adverse events in the multiple ascending dose portion of the study were reported as mild or moderate and 99% of gastrointestinal-related adverse events were reported as mild or moderate. This study also demonstrated VK2735's encouraging impact on liver fat and plasma lipids. Specifically, after 4 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%. 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%. Plasma levels of apolipoprotein B were also reduced by up to 21%. These data are particularly interesting in light of the fact that these healthy volunteers began the study with normal baseline plasma lipid levels. These study results were featured in an oral presentation last October at Obesity Week and served as the basis for our decision to continue to advance this program further in clinical development.
To this end, in the third quarter of last year, Viking initiated the Phase 2 VENTURE trial to evaluate VK2735 in patients with obesity. The VENTURE trial is a randomized, double-blind, placebo-controlled multicenter study that is evaluating the safety, tolerability, pharmacokinetics and weight loss efficacy of VK2735 administered subcutaneously once-weekly for 13 weeks. This trial was designed to enroll approximately 125 adults with obesity or adults who are overweight with at least 1 weight-related comorbid condition. Due to higher-than-expected clinician and patient interest, this trial's enrollment was increased to 176 patients and completed ahead of schedule. The VENTURE trial is evaluating weekly subcutaneous doses of VK2735 of up to 15 milligrams compared to the 10-milligram top dose evaluated in the prior Phase 1 multiple ascending dose study.
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. Secondary and exploratory endpoints will evaluate a range of additional safety and efficacy measures. We expect to report the top line results from this study in the first quarter of this year. In addition to the subcutaneous formulation of VK2735, in the first quarter of last year, Viking announced the initiation of a Phase 1 clinical study evaluating a novel tablet formulation of this molecule. This study is an extension of the Phase 1 single ascending dose and multiple ascending dose study discussed a moment ago. The oral portion of the study is a randomized, double-blind, placebo-controlled study in healthy volunteers who have a minimum body mass index of 30 kilograms per meter squared.
Subjects in this portion of the study will receive once-daily oral doses of VK2735 for 28 days. The primary objective of the study is to evaluate the safety, tolerability and pharmacokinetics of VK2735 following 28 days of oral dosing. Exploratory endpoints include changes in body weight and other pharmacodynamic markers. We expect to report the results from this study in the first quarter of this year. I'll now provide an update on our VK2809 program for the treatment of NASH and fibrosis. 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. Last May, we announced positive top line results from the ongoing Phase 2b VOYAGE study of VK2809.
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 as well as F2 and F3 fibrosis. As we reported in May, this study successfully achieved its primary endpoint with patients receiving VK2809 demonstrating 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 ranged from 38% to 55% among patients receiving VK2809 Importantly, up to 85% of patients receiving VK2809 experienced at least a 30% relative reduction in liver fat.
This level of efficacy is associated with a greater likelihood of histologic benefit in NASH. As in prior studies, VK2809 treated patients also achieved statistically significant reductions in LDL cholesterol, triglycerides and atherogenic proteins. We believe these results indicate that VK2809 has the potential to provide long-term cardiovascular benefits. The initial VOYAGE data also served to further establish VK2809's promising safety and tolerability profile. 94% of treatment-related adverse events among patients receiving VK2809 were reported as mild or moderate, discontinuation due to adverse events low and balanced among placebo and treatment arms. In particular, VK2809 demonstrated excellent gastrointestinal tolerability. In the VOYAGE study, the rates of nausea, diarrhea, stool frequency and vomiting were similar among VK2809-treated patients compared to placebo.
In November, Viking presented new data from this study at the Annual Meeting of the American Association for the Study of Liver Diseases. These new data demonstrated robust liver fat reductions among patients with or without type 2 diabetes as well as those having F2 or F3 fibrosis. Among patients with type 2 diabetes at week 12, reductions from baseline in liver fat ranged from 36% to 54% which was comparable to the reductions reported among patients without type 2 diabetes. 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. Treatment with VK2809 also demonstrated potent reductions in liver fat among patients with F2 or F3 fibrosis.
Thus, neither the presence of type 2 diabetes nor the presence of F2 or F3 fibrosis meaningfully impacted VK2809's efficacy in reducing liver fat. As steatosis and lipotoxicity are believed to be underlying drivers in NASH, these results suggest important long-term benefits across key subgroups. We recently completed the final biopsies in the VOYAGE study and look forward to reporting data on histologic changes assessed after 52 weeks of treatment in the first half of 2024. Moving to our Orphan disease program. Our second thyroid hormone receptor beta agonist, VK0214, is currently being evaluated in Phase 1b trial in patients with X-linked adrenoleukodystrophy or X-ALD. Like VK2809, VK0214 is also an orally available small molecule that is selective for the beta isoform of the thyroid hormone receptor.
X-ALD is a rare and debilitating metabolic disorder that is caused by genetic patients that disable the function of peroxisomal transporter of very long-chain fatty acids. As a result, patients are unable to efficiently metabolize very long chain fatty acids and the accumulation of these compounds is believed to contribute to the onset and progression of X-ALD. In a prior Phase 1 study, VK0214 demonstrated dose-dependent exposures, no evidence of accumulation, and the half-life consistent with anticipated once-daily dosing. Subject to received VK0214 experienced reductions in LDL cholesterol, triglycerides, apolipoprotein B and lipoprotein A. VK0214 also demonstrated an encouraging safety and tolerability profile with no serious adverse events reported and no treatment or dose-related signals observed for GI side effects, vital signs or cardiovascular measures.
The ongoing Phase 1b study of VK0214 is being conducted in patients with the adrenomyeloneuropathy or AMN form of X-ALD, which is the most common form of the disorder. This trial is a randomized, double-blind, placebo-controlled multicenter study in adult male patients with AMN. The primary objectives of the study are to evaluate the safety, tolerability and pharmacokinetics of VK0214 administered orally once daily for 28 days. The study also includes an exploratory assessment of changes in plasma levels of very long chain fatty acids. We expect to report the top line results from this study in the first half of 2024. In conclusion, 2023 was an exciting and productive year for Viking, with the company achieving significant progress with each of our clinical programs.
During the year, we reported the results from the first Phase 1 trial of VK2735, which demonstrated early signals of efficacy as well as promising safety and tolerability. We also initiated the Phase 1 clinical evaluation of a novel oral formulation of VK2735, which we believe may expand the market opportunity for this compound. In the fall of 2023, we initiated and completed the upsized enrolment of the VENTURE Phase 2 trial to evaluate VK2735's longer-term clinical benefit in patients with obesity. We look forward to reporting the results from the VENTURE Phase 2 study later this quarter, along with the Phase 1 data from the oral formulation study. We also look forward to reporting data from the VOYAGE Phase 2b study of our thyroid beta receptor agonist, VK2809 in biopsy-confirmed NASH and fibrosis.
The initial data from this study successfully achieved the primary endpoint and affirmed VK2809's best-in-class effect on liver fat along with its favorable tolerability and safety profile. We expect to report the 52-week biopsy data from this study in the first half of 2024. The Phase 1b study of VK0214 for the treatment of adrenomyeloneuropathy also continues, and we look forward to announcing the results from this trial later in the first half. Finally, we completed 2023 with a strong balance sheet and a cash position that will support our objectives for 2024 and beyond. All of us at Viking are optimistic about the year ahead and would like to extend our thanks to our shareholders, partners, investigators and importantly, the patients participating in our clinical trials for their continued support.
This concludes our prepared comments for today. Thanks very much for joining us, and we'll now open the call for questions. Operator?
