TRACON Pharmaceuticals Reports Fourth Quarter and Year-End 2023 Financial Results and

San Diego, CA – March 5, 2024 – TRACON Pharmaceuticals, Inc. (Nasdaq: TCON), a clinical stage biopharmaceutical company utilizing a cost-efficient, CRO-independent product development platform to advance its pipeline of novel targeted cancer therapeutics and to partner with other life science companies, today announced financial results for the fourth quarter and year ended December 31, 2023. The Company will host a conference call and webcast today at 4:30 PM Eastern Time / 1:30 PM Pacific Time.

“We are on track to complete enrollment of 80 patients treated with single agent envafolimab in the ongoing pivotal ENVASARC trial later this quarter. We expect to report updated response rate data shortly thereafter and before the end of this quarter, with final data anticipated in the second half of 2024,” said Charles Theuer, M.D., Ph.D., TRACON’s Chief Executive Officer. “We also expect to leverage our Product Development Platform to generate non-dilutive capital through either an additional license or by replacing a CRO and executing clinical trials for partners at a lower cost compared to a CRO but still at a premium to our costs using a pay for performance model.”

•

In December, we announced updated interim data from the ENVASARC Phase 2 pivotal trial in the initial 46 patients treated with single agent envafolimab. The objective response rate (ORR) was 15% by investigator review and 8.7% by blinded independent central review (BICR), all of which were confirmed responses. Envafolimab monotherapy was generally well tolerated and median duration of response by BICR was greater than six months. The primary endpoint of the study is achievement of an ORR by BICR in nine of 80 patients (11.25%) treated with envafolimab and median duration of response of greater than six months is a key secondary endpoint.

•

In November, we licensed our Product Development Platform (PDP) to a clinical stage biotech company for an upfront payment of $3.0 million.

•

Complete accrual of the ENVASARC pivotal trial this quarter and report updated response rate data shortly thereafter and before the end of the quarter.

Cash, cash equivalents and restricted cash were $8.6 million at December 31, 2023, compared to $17.5 million at December 31, 2022.

•

License revenue for the fourth quarter of 2023 was $3.0 million and was due to the license of our PDP to a clinical stage biotech company.

•

Research and development expenses for the fourth quarter of 2023 were $1.5 million, compared to $3.9 million for the fourth quarter of 2022. The decrease was primarily related to enrollment into only cohort C in the ongoing ENVASARC pivotal trial.

•

General and administrative expenses for the fourth quarter of 2023 were $1.1 million, compared to $2.0 million for the fourth quarter of 2022. The decrease was primarily attributable to lower legal expenses.

•

Net income for the fourth quarter of 2023 was $0.4 million, compared to a net loss of $7.0 million for the fourth quarter of 2022.

Envafolimab (KN035), a single-domain antibody against PD-L1 invented by Alphamab Oncology and licensed by TRACON, is the first approved subcutaneously injected PD-(L)1 inhibitor. Envafolimab was approved by the Chinese NMPA in November 2021 in adult patients with MSI-H/dMMR advanced solid tumors who failed systemic treatment and have no satisfactory alternative treatment options. In December 2019, Alphamab Oncology, 3D Medicines and TRACON entered into a collaboration whereby TRACON has the right to develop and commercialize envafolimab in soft tissue sarcoma in North America. Envafolimab is currently being studied in the ENVASARC Phase 2 pivotal trial in the United States sponsored by TRACON and a Phase 3 pivotal trial in combination with gemcitabine and oxaliplatin in advanced biliary tract cancer patients in China sponsored by TRACON’s corporate partners, Alphamab Oncology and 3D Medicines. TRACON has received orphan drug designation from the U.S. Food and Drug Administration for envafolimab for patients with soft tissue sarcoma and fast track designation from the U.S. Food and Drug Administration for envafolimab (KN035) for patients with locally advanced, unresectable or metastatic undifferentiated pleomorphic sarcoma (UPS) and myxofibrosarcoma (MFS) who have progressed on one or two prior lines of chemotherapy.

The ENVASARC Phase 2 pivotal trial is a multicenter, open label, randomized, non-comparative, parallel cohort study at 30 top cancer centers in the United States and the United Kingdom that began dosing in December 2020. TRACON is enrolling patients in ENVARSAC with UPS or MFS who have progressed following one or two lines of prior treatment and have not received an immune checkpoint inhibitor. A total of 80 patients will receive treatment with single agent envafolimab at 600 mg every three weeks. The primary endpoint is objective response rate by central review with duration of response a key secondary endpoint.

TRACON is a clinical-stage biopharmaceutical company utilizing a cost-efficient, CRO-independent, product development platform to advance its pipeline of novel targeted cancer therapeutics and to partner with other life science companies. The Company’s clinical-stage pipeline includes: Envafolimab, a PD-L1 single-domain antibody given by rapid subcutaneous injection that is being studied in the pivotal ENVASARC trial for sarcoma; YH001, a potential best-in-class CTLA-4 antibody in Phase 1 development; and TRC102, a Phase 2 small molecule drug candidate for the treatment of lung cancer. TRACON is actively seeking additional corporate partnerships through a profit-share or revenue-share partnership, or through franchising TRACON’s product development platform. TRACON believes it can serve as a solution for companies without clinical and commercial capabilities in the United States or who wish to become CRO-independent.
