SAN DIEGO, Aug. 14, 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 second quarter ended June 30, 2023. The Company will host a conference call and webcast today at 4:30 PM Eastern Time / 1:30 PM Pacific Time.

“We were pleased to collect the arbitration award of $22M, the initial net proceeds of which extend our cash runway into early 2024 and past expected full accrual of the ENVASARC pivotal trial,” said Charles Theuer, M.D., Ph.D., TRACON’s Chief Executive Officer. “We look forward to reporting the interim efficacy assessment from ENVASARC later this quarter, which includes a futility threshold that has already been achieved based on responses seen to date. In June, we reported that envafolimab treatment continues to generate a double-digit objective response rate (ORR) and has been well tolerated, and as such we believe that we remain on track to achieve the primary endpoint of the study, which is a minimum 11.25% ORR. Achieving a double-digit ORR with a well-tolerated safety profile positions envafolimab to become a potentially compelling treatment option for patients with the refractory sarcoma subtypes of UPS and MFS. The sole approved treatment for these patients is Votrient, which achieved a 4% ORR and carries a black box warning for fatal liver toxicity.”

Recent Corporate Highlights

• In June, we announced an ongoing double-digit ORR for single agent envafolimab in patients with two on-study scans in the ongoing ENVASARC Phase 2 pivotal trial without any > Grade 2 drug related toxicity. The single agent envafolimab ORR exceeded the futility rule that will be applied at the interim efficacy analysis expected later this quarter, and full ENVASARC accrual is expected in the fourth quarter.
  
  
• In July, we announced collection of the arbitration award of $22M from I-Mab Biopharma, with the initial net proceeds of $7.1 million expected to fund the Company’s operations, as currently planned, into early 2024.
  
  

Expected Upcoming Milestones

• 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 IDMC from 46 patients who receive envafolimab as a single agent, which we expect later this quarter as the ENVASARC trial has enrolled 180 patients to date, including 56 of the 80 expected patients in cohort C of single agent envafolimab treatment that is the basis for determination of the primary endpoint of the study, which is a minimum 11.25% ORR.
  
  
• Complete accrual of the ENVASARC pivotal trial in the fourth quarter of 2023.
  
  
• Leverage TRACON’s cost-efficient, CRO-independent product development platform to generate non-dilutive capital by the end of 2024.
  
  
• Final data from ENVASARC pivotal trial in mid-2024.
  
  

Second Quarter 2023 Financial Results

• Cash, cash equivalents and restricted cash were $1.9 million at June 30, 2023, compared to $17.5 million at December 31, 2022, which does not include the $7.1 million in initial net proceeds from the arbitration award that was received in July. TRACON’s pro forma cash position of $9.0 million is expected to fund the Company into the first quarter of 2024.
  
  
• An additional $4.4M of the arbitration award remains in a client trust account administered by our law firm at this time, the disbursement of which is predicated on discussions as to the amount of success-based deferred legal fees the firm is due.
  
  
• Collaboration revenue was $9.0 million for the second quarter of 2023, compared to nil for the second quarter of 2022. The increase was related to the termination of the TJ4309 license.
  
  
• Research and development expenses for the second quarter of 2023 were $3.5 million, compared to $2.9 million for the second quarter of 2022. The increase was primarily related to increased enrollment into the ENVASARC pivotal trial.
  
  
• General and administrative expenses for the second quarter of 2023 were $1.9 million, compared to $3.3 million for the second quarter of 2022. The decrease was primarily attributable to lower legal expenses.
  
  
• Net loss for the second quarter of 2023 was $6.3 million, compared to $6.2 million for the second quarter of 2022. In July we collected the arbitration award from I-Mab which will result in a one-time gain in the third quarter of 2023 of $13.0 million.

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.
