Structure Therapeutics Inc

Previous wording

Our initial focus is on G-protein coupled receptors (“GPCRs”) as a therapeutic target class. GPCRs regulate numerous diverse physiological and pathological processes, and approximately one in every three marketed medicines targets GPCR-associated pathways. By leveraging our world-class GPCR know-how, we aim to design differentiated small molecule therapies to overcome the limitations of biologics and peptide therapies targeting this family of receptors. We are developing GSBR-1290, our oral small molecule product candidate targeting the validated glucagon-like-peptide-1 receptor (“GLP-1R”) for the treatment of type 2 diabetes mellitus (“T2DM”) and obesity. We completed our Phase 1 single ascending dose (“SAD”) study of GSBR-1290 in September 2022. GSBR-1290 was generally well tolerated and demonstrated dose-dependent pharmacokinetic (“PK”) and pharmacodynamic (“PD”) activity. We submitted an investigational new drug (“IND”) application to the U.S. Food and Drug Administration (“FDA”) to support initiation of a Phase 1b study in T2DM and obesity and received FDA allowance in September 2022. We initiated the Phase 1b multiple ascending dose (“MAD”) study of GSBR-1290 in January 2023 and completed dosing in otherwise healthy overweight subjects in March 2023. In May 2023, we submitted a protocol amendment to the FDA and initiated dosing of the Phase 2a proof-of-concept study in T2DM and obesity. We reported topline data for the 28-day Phase 1b MAD study in September 2023, in which GSBR-1290 was generally well- tolerated with no adverse event-related discontinuations and demonstrated an encouraging safety profile and significant weight loss of up to 4.9% placebo-adjusted, supporting once-daily dosing. In December 2023, we reported clinically meaningful topline data from our Phase 2a T2DM cohort, interim results from our Phase 2a obesity cohort and topline data from a Japanese ethno-bridging study of GSBR-1290. These data demonstrated that GSBR-

1290 was generally well-tolerated, with no treatment-related serious adverse events (“SAEs”) over 12 weeks, with only one participant discontinuing the study due to adverse events in the T2DM cohort and none in the obesity cohort. GSBR-1290 also showed significant reduction in weight in the obesity cohort at 8 weeks, and significant reductions in hemoglobin A1c (“HbA1c”) and weight in the T2DM cohort. In June 2024, we reported positive topline data from our Phase 2a obesity study, in which GSBR-1290 demonstrated a clinically meaningful and statistically significant placebo-adjusted mean decrease in weight of 6.2% at 12 weeks (p<0.0001, using least-squares means (“LSM”) and analyzed based on the primary efficacy estimand using a mixed model for repeated measures) and demonstrated generally favorable safety and tolerability results following repeated, daily dosing up to 120mg. Furthermore, we explored a new tablet formulation of GSBR-1290 in a capsule to tablet PK study, which demonstrated a placebo-adjusted mean weight loss of up to 6.9% with the tablet formulation at 12 weeks (p<0.0001, using LSM and analyzed based on the primary efficacy estimand using a mixed model for repeated measures). We are submitting an IND to the FDA in the third quarter of 2024 to support initiation of a trial in chronic weight management and expect to initiate a 36-week Phase 2b study for obesity in the fourth quarter of 2024. Details of the Phase 2 development plan in T2DM are expected to be determined in the second half of 2024.

In July 2024, we submitted an IND to the FDA to support initiation of a Phase 2b study in chronic weight management and received FDA allowance in August 2024. In the fourth quarter of 2024, we initiated the Phase 2b ACCESS study, a randomized, double-blind, placebo-controlled, dose-range finding study of GSBR-1290 in approximately 220 adult participants living with obesity (body mass Index ≥ 30 kg/m2), or overweight (body mass index ≥ 27 kg/m2) with at least one weight-related comorbidity. Participants will start at 5mg of GSBR-1290 (or placebo) with a 4-week titration schedule, reaching target doses of 45 mg, 90 mg and 120 mg. The primary endpoint is percent change in body weight from baseline to week 36. Secondary endpoints include safety and tolerability of the monthly titration scheme, as well as pharmacokinetics of GSBR-1290. A second randomized, double-blind, placebo-controlled dose-range finding Phase 2 study of GSBR-1290, known as ACCESS II, aims to enroll approximately 82 adult participants living with obesity or overweight with at least one weight-related comorbidity. The study is designed to evaluate two higher doses of GSBR-1290. Participants will start at 5mg of GSBR-1290 (or placebo) and will follow a 4-week titration schedule up to target doses of 120 mg, 180 mg and 240 mg. We expect to dose the first patient in the ACCESS II study by the end of 2024. We expect to report topline data from both the ACCESS and ACCESS II studies in the fourth quarter of 2025.

We are a Cayman Islands exempted company incorporated with limited liability. We were initially formed as a Delaware limited liability company in 2016 under the name ShouTi Inc., and reorganized as a Cayman Islands exempted company in February 2019. Our primary activities to date have included organizing and staffing our company, business and scientific planning, raising capital, conducting research and development activities, entering into strategic and corporate structuring transactions, enabling manufacturing activities in support of our product candidate development efforts, and establishing our intellectual property portfolio, and providing general and administrative support for these activities. We do not have any product candidates approved for sale and have not generated any revenue from our products. Since our inception, we have incurred net operating losses and negative cash flows from operations. We had net losses of $52.1 million and $41.3 million in the six months ended June 30, 2024 and 2023, respectively. As of June 30, 2024, we had an accumulated deficit of $258.6 million. Historically, prior to our IPO, we have financed our operations primarily through the private placement of equity securities. In February 2023, we completed our IPO of our ADSs, in which we issued and sold an aggregate of 12,351,000 ADSs (inclusive of 1,611,000 ADSs purs uant to the exercise by the underwriters of their option) at a price of $15.00 per ADS for net cash proceeds of approximately $166.7 million, net of underwriting discounts and commissions and estimated offering costs. Upon the closing of the IPO, all outstanding shares of redeemable convertible preferred shares automatically converted into 67,018,087 ordinary shares. Subsequent to the closing of the IPO, there were no shares of redeemable convertible preferred shares outstanding. In September 2023, we entered into a share purchase agreement with certain institutional investors (the “Purchasers”), pursuant to which we agreed to sell and issue to the Purchasers an aggregate of 21,617,295 ordinary shares and 2,401,920 newly designated non-voting ordinary shares at a purchase price of $12.49 per share (or the equivalent of $37.47 per ADS), the closing price of our ADS on the Nasdaq Global Market on September 28, 2023. We completed the Private Placement in October 2023 and received approximately $281.5 million in net proceeds after deducting placement agent fees and other private placement expenses. In June 2024, we closed our Follow-On Offering, in which we issued and sold 10,427,017 ADSs, including the full exercise of the Underwriters’ Option, and received $512.7 million in net proceeds, after deducting the underwriting discounts and commissions and estimated offering expenses.

We expect to continue to incur significant and increasing expenses and operating losses for the foreseeable future, particularly if and as we continue to invest in our research and development activities and initiate additional clinical trials, expand our product pipeline, hire additional personnel and invest in and grow our business, maintain, expand and protect our intellectual property portfolio, and seek regulatory approvals for and commercialize any approved product candidates. In addition, we expect to incur additional costs associated with operating as a public company, including significant legal, audit, accounting, regulatory, consulting, and tax-related services associated with being a public company, compliance with Nasdaq listing and SEC requirements, director and officer insurance premiums and investor relations costs that we did not incur as a private company. As a result, we will need substantial additional capital to develop our product candidates and fund operations for the foreseeable future. Moreover, we may in the future seek to acquire or invest in additional businesses, products, or technologies that we believe could complement or enhance our product, enhance our technical capabilities or otherwise offer growth opportunities, although we currently have no agreements or understandings with respect to any such acquisitions or investments. Until such time as we can generate significant revenue from our products, if ever, we expect to finance our operations through the public or private sale of equity, government or private party grants, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. If we are unable to obtain additional funding, we could be forced to delay, reduce or eliminate some or all of our research and development programs, product portfolio expansion or any commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations.

Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the public or private sale of equity, government or private party grants, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest may be diluted, and the terms of these securities may include liquidation or other preferences and anti-dilution protections that could adversely affect your rights as a holder of our ADSs. Additional debt or preferred equity financing, if available, may involve agreements that include restrictive covenants that may limit our ability to take specific actions, such as incurring debt, making capital expenditures or declaring dividends, which could adversely impact our ability to conduct our business, and may require the issuance of warrants, which could potentially dilute your ownership interest. If we raise funds through strategic collaborations or other similar arrangements with third-parties, we may have to relinquish valuable rights to our platform technology, future revenue streams, research programs or product candidates or may have to grant licenses on terms that may not be favorable to us and/or may reduce the value of our ordinary shares.
