Structure Therapeutics Inc. is a clinical-stage global biopharmaceutical company at the forefront of developing novel oral small molecule therapeutics to address chronic diseases with significant unmet medical needs. The company's differentiated technology platform leverages both structure-based drug discovery and computational chemistry expertise to design innovative treatments targeting G-protein coupled receptors (GPCRs), a family of receptors that regulate numerous physiological and pathological processes.
Business Overview and History
Structure Therapeutics was initially formed as a Delaware limited liability company in 2016 under the name ShouTi Inc. In February 2019, the company was reorganized as a Cayman Islands exempted company and changed its name to Structure Therapeutics Inc. The company's primary operating activities were carried out through its subsidiaries, including Structure Therapeutics USA Inc. (previously known as ShouTi Inc.), Annapurna Bio, Inc., and Gasherbrum Bio, Inc.
In April 2019, Structure Therapeutics entered into a share exchange agreement, as a result of which Annapurna, Gasherbrum, and Structure Therapeutics USA became wholly-owned subsidiaries of the company. Over the next few years, the company continued to expand its corporate structure, incorporating additional subsidiaries in Hong Kong, China, and the United States to support its research and development activities.
In the early years of the company's operations, it faced challenges in organizing and staffing the organization, as well as securing the necessary capital to fund its research and development programs. The company financed its operations primarily through the private placement of equity securities, raising approximately $198 million in gross proceeds prior to its initial public offering.
Despite these initial challenges, Structure Therapeutics made progress in building its intellectual property portfolio and advancing its pipeline of product candidates targeting G-protein coupled receptors (GPCRs), an important class of drug targets. The company's structure-based drug discovery platform and expertise in computational chemistry enabled it to develop a diverse portfolio of small molecule product candidates, including aleniglipron (GSBR-1290) for the treatment of obesity and related conditions, ACCG-2671 for obesity, and LTSE-2578 for idiopathic pulmonary fibrosis.
The company's primary focus is on developing treatments for metabolic, cardiovascular, and pulmonary diseases. Its most advanced product candidate is aleniglipron (GSBR-1290), an oral and biased small molecule agonist of the glucagon-like peptide-1 receptor (GLP-1R) that is currently in two Phase 2 clinical studies for the treatment of obesity, overweight, and related conditions. In June 2024, Structure Therapeutics reported positive topline data from its Phase 2a obesity study, in which aleniglipron demonstrated a clinically meaningful and statistically significant placebo-adjusted mean decrease in weight of 6.2% at 12 weeks.
The company's pipeline also includes ACCG-2671, an oral small molecule amylin receptor agonist development candidate for the treatment of obesity, which is expected to enter Phase 1 clinical development by the end of 2025. Additionally, Structure Therapeutics is developing ANPA-0073, an oral small molecule agonist targeting the apelin APJ receptor, for selective or muscle-sparing weight loss, and LTSE-2578, an oral small molecule antagonist of the lysophosphatidic acid 1 receptor (LPA1R) for the treatment of idiopathic pulmonary fibrosis (IPF).
Financial Performance
For the fiscal year ended December 31, 2024, Structure Therapeutics reported no revenue, as the company's product candidates are still in the clinical development stage. The company incurred a net loss of $122.53 million, with research and development expenses of $108.81 million and general and administrative expenses of $49.41 million.
In the most recent quarter (Q3 2024), Structure Therapeutics reported no revenue and a net loss of $36.48 million. The company has not generated any revenue to date, as its product candidates are still in various stages of clinical development.
The global obesity and metabolic disorder treatment market, in which Structure Therapeutics operates, is expected to grow at a compound annual growth rate (CAGR) of over 7% from 2023 to 2030. This growth is driven by the increasing prevalence of obesity and the development of novel therapeutics, presenting significant opportunities for companies like Structure Therapeutics.
Liquidity
As of December 31, 2024, the company had a strong cash, cash equivalents, and short-term investments position of $883.50 million, which it believes will be sufficient to fund its projected operations and key clinical milestones through at least 2027, excluding potential Phase 3 registrational studies for aleniglipron.
The company's financial position has been bolstered by several key financing events. In February 2023, Structure Therapeutics completed its initial public offering (IPO), raising $166.70 million in net proceeds. This was followed by a $281.50 million private placement in October 2023 and a $512.70 million follow-on offering in June 2024. These transactions have provided the company with the necessary capital to advance its robust pipeline of product candidates.
Structure Therapeutics' liquidity position is strong, with a debt-to-equity ratio of 0.004 as of December 31, 2024. The company's current ratio and quick ratio both stand at 24.74, indicating a high level of short-term liquidity. The company does not appear to have any available credit lines disclosed.
Product Segments
Structure Therapeutics' business is organized into the following key product segments:
GLP-1R Program: The company's most advanced product candidate, aleniglipron (GSBR-1290), is an oral small molecule selective glucagon-like-peptide-1 receptor (GLP-1R) agonist currently in two Phase 2 clinical trials for the treatment of obesity, overweight, and related conditions. In the Phase 2a obesity study, aleniglipron demonstrated a clinically meaningful and statistically significant placebo-adjusted mean decrease in weight of 6.2% at 12 weeks. A new tablet formulation of aleniglipron showed a placebo-adjusted mean weight loss of up to 6.9% at 12 weeks. The company has initiated a Phase 2b study in chronic weight management and expects to report topline data in the fourth quarter of 2025.
Amylin Receptor Program: Structure Therapeutics is advancing its oral small molecule amylin receptor agonist program and has declared ACCG-2671 as its development candidate. In preclinical studies, ACCG-2671 demonstrated potent and balanced in vitro activities toward amylin and the calcitonin receptors, as well as robust in vivo efficacy and a favorable PK and safety profile supporting once-daily oral dosing in humans. The company expects to initiate a Phase 1 clinical study of ACCG-2671 in the fourth quarter of 2025.
