TRACON Pharmaceuticals Reports Third Quarter 2020 Financial Results and Provides Corporate Update

SAN DIEGO, Nov. 10, 2020 (GLOBE NEWSWIRE) — TRACON Pharmaceuticals (NASDAQ:TCON), a clinical stage biopharmaceutical company focused on the development and commercialization of novel targeted cancer therapeutics and utilizing a cost efficient, CRO-independent product development platform to partner with ex-U.S. companies to develop and commercialize innovative products in the U.S., today announced financial results for the third quarter ended September 30, 2020. The Company will host a conference call and webcast today at 4:30 PM Eastern Time / 1:30 PM Pacific Time.

“We made great progress during the quarter by securing capital from dedicated healthcare funds that extends our runway past expected ENVASARC registration trial interim data and into 2022. We expect to enroll patients at multiple sites in the ENVASARC trial this year and also expect our partners to submit envafolimab for approval in China before the end of the year,” said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. “We are focused on enrolling the ENVASARC trial expeditiously so we may deliver interim data in 2021, final data in 2022, and assuming positive clinical data and regulatory approval, potentially commercialize envafolimab in 2023 and thereby address a high unmet need within sarcoma.”

Recent Corporate Highlights

Envafolimab

• In September, TRACON highlighted data from the registration trial of envafolimab in MSI-H/dMMR cancer that showed a 32% confirmed objective response rate (ORR) in patients (n=41) with MSI-H/dMMR colorectal cancer (CRC) who failed a fluoropyrimidine, oxaliplatin and irinotecan, and had at least two on-study tumor assessments. Twelve-month duration of response (DOR) was 75% and 12-month overall survival (OS) was 65%. The ORR in the overall population (n=103) was 43%, 12-month DOR was 92% and 12-month OS was 75%. Envafolimab demonstrated good tolerability and safety and there continued to be no infusion-related reactions. The 32% ORR is nearly identical to the 28% ORR reported for Opdivo and 33% ORR reported for Keytruda in separate trials of MSI-H/dMMR CRC patients who failed a fluoropyrimidine, oxaliplatin and irinotecan.

TRC102

• In October, TRACON announced orphan drug designation from the U.S. FDA for TRC102 in malignant glioma, including glioblastoma. TRC102 is a small molecule inhibitor of DNA base inhibitor repair being studied in Phase 1 and Phase 2 trials sponsored by the National Cancer Institute.

Corporate

• In August, TRACON announced financings of approximately $10.0 million in the aggregate with multiple healthcare focused institutional investors through private placements of its common stock and pre-funded warrants. The financings were completed at market price, and TRACON expects that the net proceeds will extend its cash runway into 2022.

Expected Key Upcoming Milestones

• Enroll patients at multiple sites into the ENVASARC registration trial during the fourth quarter of 2020.
• Submission of envafolimab for approval in MSI-H/dMMR CRC to the National Medicinal Products Administration (NMPA) in China by our corporate partners 3D Medicines and Alphamab Oncology.
• Independent Data Monitoring Committee review of ENVASARC safety data in 1H 2021.
• FDA decision on orphan drug designation for envafolimab in sarcoma in 1H 2021.
• Interim ENVASARC efficacy and safety data in mid-2021.

Third Quarter 2020 Financial Results

• Cash and cash equivalents were $26.5 million at September 30, 2020, compared to $16.4 million at December 31, 2019. We expect our current cash and cash equivalents to fund operations into the first quarter of 2022.
• Research and development expenses for the third quarter of 2020 were $1.8 million, compared to $3.1 million for the third quarter of 2019.
• General and administrative expenses for the third quarter of 2020 were $2.1 million, compared to $2.0 million for the third quarter of 2019.
• Net loss for the third quarter of 2020 was $4.0 million, compared to $5.2 million for the third quarter of 2019.

A live webcast of the conference call will be available online from the Investor/Events and Presentation page of the Company’s website at www.traconpharma.com.

After the live webcast, a replay will remain available on TRACON’s website for 60 days.

About Envafolimab

Envafolimab (KN035), a novel, single-domain antibody against PD-L1, is the first subcutaneously injected PD-(L)1 inhibitor to be studied in registration trials. Envafolimab is currently dosing in a Phase 2 registration trial as a single agent in MSI-H/dMMR advanced solid tumor patients and a Phase 3 registration trial in combination with gemcitabine and oxaliplatin in advanced biliary tract cancer patients in China sponsored by TRACON’s corporate partners, 3D Medicines and Alphamab Oncology. In the Phase 2 registration trial, the confirmed ORR in MSI-H/dMMR CRC patients treated with envafolimab who failed a fluoropyrimidine, oxaliplatin and irinotecan was 32%, which was similar to the 28% confirmed ORR reported in the Opdivo package insert in MSI-H/dMMR CRC patients who failed a fluoropyrimidine, oxaliplatin and irinotecan and the 33% confirmed ORR reported for Keytruda in MSI-H/dMMR CRC patients who failed a fluoropyrimidine, oxaliplatin and irinotecan in cohort A of KEYNOTE-164.

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 US FDA in malignant glioma, including glioblastoma.

About TRC253

TRC253 is a Phase 3 ready novel, orally bioavailable small molecule drug that is a potent, high affinity competitive inhibitor of the androgen receptor (AR) and AR mutations, including the F877L mutation. The AR F877L mutation results in an alteration in the AR ligand binding domain that confers resistance to therapies for prostate cancer. Therapies targeting the AR have demonstrated clinical efficacy by extending time to disease progression, and in some cases, the survival of patients with metastatic castration-resistant prostate cancer. However, resistance to these agents is often observed and several molecular mechanisms of resistance have been identified, including gene amplification, overexpression, alternative splicing, and point mutation of the AR. TRC253 recently completed a Phase 1/2 clinical trial in prostate cancer conducted by TRACON.   TRACON believes TRC253 can be developed and commercialized successfully in China and is actively seeking a strategic collaboration.

About TJ004309

TJ004309 is a novel, humanized antibody against CD73, an ecto-enzyme expressed on stromal cells and tumors that converts extracellular adenosine monophosphate (AMP) to adenosine, which is highly immunosuppressive.   TJ004309 is currently being studied in a Phase 1 trial 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.

About TRACON

TRACON develops targeted therapies for cancer utilizing a capital efficient, CRO independent, product development platform. 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; TRC253, a Phase 3 ready small molecule drug candidate for the treatment of prostate cancer; TRC102, a Phase 2 small molecule drug candidate for the treatment of lung cancer; and TJ004309, a CD73 antibody in Phase 1 development for the treatment of advanced solid tumors. TRACON is actively seeking additional corporate partnerships whereby it leads U.S. regulatory and clinical development and shares in the cost and risk of clinical development and leads U.S. commercialization.  In these partnerships TRACON believes it can serve as a solution for companies without clinical and commercial capabilities in the U.S.  To learn more about TRACON and its product pipeline, visit TRACON’s website at www.traconpharma.com.
