TRACON Pharmaceuticals Reports Fourth Quarter and Year-End 2022 Financial Results and Provides Corporate Update

SAN DIEGO, March 08, 2023 (GLOBE NEWSWIRE) — 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, 2022. The Company will host a conference call and webcast today at 4:30 PM Eastern Time / 1:30 PM Pacific Time.

“The significant progress we achieved in the fourth quarter sets up 2023 to be a potentially transformational year for TRACON,” said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. “In December we announced interim efficacy results from the ongoing ENVASARC pivotal trial demonstrating that envafolimab achieved a double-digit objective response rate, both as a single agent and in combination with Yervoy, in 36 patients with refractory sarcoma. We also secured a non-dilutive non-recourse financing of up to $30 million related to the I-Mab arbitration award decision which we expect this month, of which $3.5 million was funded in December. Importantly, accrual in ENVASARC remains ahead of projections and we expect the second and final interim efficacy analysis of 92 patients in the third quarter, after each patient has had two on-study scans, and to complete accrual before year end, leading to final data in 2024.”

Recent Corporate Highlights

• In November 2022, we announced dosing of the first patient in a Phase 1/2 trial that studies envafolimab with our proprietary CTLA-4 antibody YH001 in combination with doxorubicin in front line sarcoma.
• In November 2022, we completed the Phase 1 study of the CD73 antibody TJ4309, triggering I-Mab’s right to reacquire the asset for a payment to TRACON of $9M.
• In December 2022, we announced positive interim results in the ENVASARC Phase 2 pivotal trial based on a double-digit objective response rate (ORR) by central radiographic review in the cohort of single agent envafolimab (N=18) and the cohort of envafolimab given in combination with Yervoy (N=18). The primary endpoint of the pivotal ENVASARC trial is achievement of an 11.25% ORR by central radiographic review in either 80 patient cohort.
• In December 2022, we announced a non-recourse non-dilutive financing of up to $30M related to the arbitration with I-Mab. We received $3.5M up front and the remainder will be available subject to the award exceeding a threshold and satisfaction of other conditions.

Expected Upcoming Milestones

• Report the binding decision of the International Chamber of Commerce Arbitration Panel on the ongoing arbitration involving the TJ4309 and bispecific antibody agreements with I-Mab Biopharma where we are seeking to recover over $200 million in damages, which we expect in the first quarter of 2023.
• Report the second and final interim efficacy analysis from the ENVASARC pivotal trial following the review of more than 12 weeks of efficacy data (including two on-study CT scans) by the independent data monitoring committee from 46 patients who receive envafolimab as a single agent and 46 patients who receive envafolimab in combination with Yervoy^®, which we expect in the third quarter of 2023.
• Complete full accrual of the ENVASARC pivotal trial before the end of 2023.
• Report Phase 1 data from the Phase 1/2 clinical trial of YH001 in combination with envafolimab and doxorubicin in patients with soft tissue sarcoma, which we expect in the second half of 2023.

Fourth Quarter 2022 Financial Results

• Cash and cash equivalents were $17.4 million at December 31, 2022, compared to $24.1 million at December 31, 2021, and is expected to fund the company into mid-2023.
• Research and development expenses for the fourth quarter of 2022 were $3.9 million, compared to $3.1 million for the fourth quarter of 2021.
• General and administrative expenses for the fourth quarter of 2022 were $2.0 million, compared to $4.6 million for the fourth quarter of 2021. The decrease was primarily attributable to legal expenses incurred in the fourth quarter of 2021 in connection with the arbitration with I-Mab.
• Net loss for the fourth quarter of 2022 was $7.0 million, compared to $7.7 million for the fourth quarter of 2021.

About Envafolimab

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 pivotal ENVASARC Phase 2 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 as well as multiple Phase 1 and Phase 2 clinical trials 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 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.

About ENVASARC (NCT04480502)

The ENVASARC 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 expects the trial to enroll more than 160 patients with UPS or MFS who have progressed following one or two lines of prior treatment and have not received an immune checkpoint inhibitor, with 80 patients enrolled into a cohort of treatment with single agent envafolimab at 600 mg every three weeks and 80 patients enrolled into a cohort of treatment with envafolimab at 600 mg every three weeks with Yervoy^®. The primary endpoint is objective response rate by central review with duration of response a key secondary endpoint.

About YH001

YH001 is an IgG1 antibody against CTLA-4 that has shown enhanced antibody dependent cellular cytotoxicity and complement dependent cytotoxicity in vitro. In preclinical studies YH001 demonstrated superior T cell activation and superior tumor growth inhibition activity compared to ipilimumab. YH001 also demonstrated superior activity compared to ipilimumab in human transgenic mouse tumor models when combined with a PD-(L)1 antibody. In these models, single agent YH001 depleted regulatory T cells and increased CD8+ T cells in tumor tissue. YH001 is being studied with envafolimab and doxorubicin in a Phase 1/2 clinical trial sponsored by TRACON (NCT05448820), and has been studied in multiple Phase 1 trials in China and Australia sponsored by TRACON’s corporate partner Eucure, a division of Biocytogen.

About TRC102

TRC102 (methoxyamine) is a novel small molecule inhibitor of the DNA base excision repair pathway, which is a pathway that causes resistance to alkylating and antimetabolite chemotherapeutics. TRC102 is currently being studied in multiple Phase 1 and Phase 2 clinical trials sponsored by the National Cancer Institute through a Cooperative Research and Development Agreement (CRADA) and has orphan drug designation from the FDA in malignant glioma, including glioblastoma.

About TJ004309

TJ004309 is a novel, humanized antibody against CD73, an ecto-enzyme expressed on stromal cells and tumors that converts extracellular adenosine monophosphate to adenosine, which is highly immunosuppressive.  TJ004309 was studied in a Phase 1 trial sponsored by TRACON (NCT03835949) to assess safety and preliminary efficacy as a single agent and when combined with the PD-L1 checkpoint inhibitor Tecentriq^® in patients with advanced solid tumors.
