SAN DIEGO, Feb. 28, 2018 (GLOBE NEWSWIRE) -- TRACON Pharmaceuticals (NASDAQ:TCON), a clinical stage biopharmaceutical company focused on the development and commercialization of novel targeted therapeutics for cancer and wet age‐related macular degeneration, today announced financial results for the fourth quarter and year ended December 31, 2017.
Fourth Quarter 2017 and Recent Corporate Highlights
- In February, TRACON’s partner, Santen Pharmaceutical Co. Ltd. (Santen), reported Phase I/II data for DE‑122 (carotuximab) in patients with refractory wet age-related macular degeneration (AMD) at the 15th Annual Angiogenesis, Exudation, and Degeneration meeting organized by Bascom Palmer Eye Institute. The study assessed the safety, tolerability and bioactivity of a single intravitreal injection of DE-122 at four dose levels in 12 subjects with wet AMD refractory to vascular endothelial growth factor (VEGF) inhibitors. Improvement was observed in mean change in central retinal subfield thickness (CST) based on the spectral domain optical coherence tomography (SD-OCT) suggesting bioactivity of DE-122 in these refractory wet AMD patients. No serious adverse events were reported. Based on these results, Santen previously advanced DE-122 into a Phase 2a randomized controlled trial assessing the efficacy and safety of intravitreal injections in combination with Lucentis® (ranibizumab) compared to Lucentis monotherapy in patients with wet AMD that continues to enroll subjects, and which resulted in TRACON receiving a $7.0 million milestone payment.
- In January, initial data from the ongoing open-label, non-randomized Phase 1b/2 study of TRC105 and Nexavar® (sorafenib) in patients with advanced hepatocellular carcinoma (HCC) were presented by Dr. Kanwal Raghav from the University of Texas MD Anderson Cancer Center at the 2018 ASCO Gastrointestinal Cancers Symposium. Partial responses by RECIST 1.1 occurred in 25% (2 of 8) of evaluable patients and a reduction of 50% or greater in alpha fetoprotein (AFP) concentration occurred in 38% (3 of 8) of evaluable patients, including both partial responses. Reduction in AFP, a tumor marker expressed in patients with HCC, in early treatment may help identify a favorable response to treatment. Adverse events typical of each drug were observed but did not increase in frequency or severity when the drugs were administered concurrently. The 25% response rate seen in this trial is consistent with the 25% (5 of 20) response rate reported in a Phase 1/2 trial of TRC105 and Nexavar conducted by the National Cancer Institute and published in Clinical Cancer Research in 2017. The response rates observed in both trials compare favorably with the 2% and 3% response rates in HCC patients reported for single agent Nexavar in its pivotal studies. The trial is currently ongoing, and we expect to complete the enrollment of approximately 33 patients by the end of 2018.
- In December, TRACON licensed development and commercialization rights outside of ophthalmology indications to TRC105 in China, Hong Kong, Macau, and Taiwan to Ambrx. Deal terms included a $3.0 million upfront payment to TRACON, up to $140.5 million in development and commercial milestones and potential high single digit to low teen royalties from net sales of TRC105 in the Ambrx territories. Ambrx is expected to file an IND later this year and to subsequently begin clinical development of TRC105 in China.
- In December, Brian Daniels, M.D., was appointed to TRACON’s Scientific Advisory Board. Dr. Daniels was Senior Vice President at Bristol-Myers Squibb until 2014, where he chaired the development investment committee and oversaw the development of Sprycel® (dasatinib), Ixempra® (ixabepilone), Yervoy® (ipilumumab), Empliciti® (elotuzumab), and Opdivo® (nivolumab). He is currently a venture partner at 5AM Ventures, and previously held senior level development-related positions at Merck and Genentech. In addition, Dr. Daniels previously served in multiple academic roles in the Department of Medicine at the University of California, San Francisco.
- In November, the first patient was dosed in a Phase 1b clinical trial of TRC105 in combination with Opdivo in patients with non-small cell lung cancer. The Phase 1b clinical trial is an open-label, dose-escalation and expansion cohort study of TRC105 and Opdivo in patients with non-small cell lung cancer that have received prior chemotherapy. The primary objectives of the Phase 1b study are to assess the safety of TRC105 when dosed with Opdivo, determine its recommended Phase 2 dose and evaluate the response rate. The trial incorporates tumor biopsy testing to determine if there is a correlation of tumor myeloid cell infiltration with response, in order to allow for potential biomarker-directed therapy in lung cancer patients.
- In November, TRACON presented updated data from the Phase 1b/2 study of TRC105 and Votrient® (pazopanib) in patients with soft tissue sarcoma, including angiosarcoma, at the Connective Tissue Oncology Society (CTOS) annual meeting. Median progression-free survival (PFS) was 7.8 months in 13 VEGF inhibitor naïve angiosarcoma patients treated with the combination of TRC105 and Votrient using either 10 mg/kg weekly dosing or the hybrid dosing schedule of TRC105. The reported median PFS compares favorably to the median PFS of 3 months reported in a retrospective study of single agent Votrient in patients with angiosarcoma. In the 17 patients who received prior treatment for metastatic disease, treatment duration on TRC105 and Votrient exceeded the duration of the most recent prior therapy in 7 of 12 VEGF naïve angiosarcoma patients and 2 of 5 patients who received a VEGF inhibitor as part of their most recent prior therapy. Treatment with the combination of TRC105 and Votrient continued to be well-tolerated and allowed for dosing of the combination for more than two years in the two patients who experienced complete responses to treatment.
- Enrollment continues in the Phase 1/2 trial of TRC253, TRACON’s product candidate for treating prostate cancer that was in-licensed from Janssen. The Phase 1/2 trial is designed to assess the safety, determine a recommended Phase 2 dose and assess response by prostate-specific antigen (PSA) levels. If Janssen opts to reacquire TRC253 prior to or following completion of the Phase 1/2 trial, TRACON is entitled to receive a $45.0 million opt-in payment, up to $137.5 million in potential milestone payments and a low single digit royalty.
“We achieved important progress across our pipeline and continued to position the Company well for long-term success during the fourth quarter and throughout 2017,” said Charles Theuer, M.D., Ph.D., President and CEO of TRACON. “Most importantly, our pivotal Phase 3 TAPPAS trial of TRC105 in angiosarcoma continues to enroll well across sites in the U.S. and now Europe, with the key interim analysis projected for later this year. Moreover, our recent partnership with Ambrx expands the development and potential commercial opportunity of TRC105 into China.”
Expected Additional 2018 Milestones
- Completion of the dose escalation portion of the Phase 1/2 trial of TRC253 in patients with prostate cancer is expected in mid-2018.
- Announcement of top-line data from the randomized Phase 2 TRAXAR trial of TRC105 in combination with Inlyta for patients with advanced or metastatic renal cell carcinoma is expected in mid-2018.
- Announcement of the results of the interim analysis from the Phase 3 pivotal TAPPAS trial of TRC105 in angiosarcoma is expected in the second half of 2018.
- Presentation of data from the Phase 1b trial of TRC105 in combination with Opdivo in patients with non-small cell lung cancer is expected in the second half of 2018.

About Carotuximab (TRC105)
TRC105 is a novel, clinical stage antibody to endoglin, a protein overexpressed on proliferating endothelial cells that is essential for angiogenesis, the process of new blood vessel formation. TRC105 is currently being studied in a pivotal Phase 3 trial in angiosarcoma and multiple Phase 2 clinical trials, in combination with VEGF inhibitors. TRC105 has received orphan designation for the treatment of soft tissue sarcoma in both the U.S. and EU. The ophthalmic formulation of TRC105, DE-122, is currently in a randomized Phase 2 trial for patients with wet AMD. For more information about the clinical trials, please visit TRACON’s website at www.traconpharma.com/clinical_trials.php.
TRC253 is a novel, orally bioavailable small molecule that is a potent, high affinity competitive inhibitor of the androgen receptor (AR) and AR mutations, including the F876L (also known as F877L) mutation. The AR F876L mutation results in an alteration in the AR ligand binding domain that confers resistance to therapies for prostate cancer. Activation of the AR is crucial for the growth of prostate cancer at all stages of the disease. 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.
TRACON develops targeted therapies for cancer and ophthalmic diseases. The Company’s clinical-stage pipeline includes: TRC105, an endoglin antibody that is being developed for the treatment of multiple cancers; DE-122, the ophthalmic formulation of TRC105 that is being developed in wet AMD through a collaboration with Santen Pharmaceutical Company Ltd.; TRC102, a small molecule being developed for the treatment of lung cancer and glioblastoma; and TRC253, a small molecule being developed for the treatment of prostate cancer.
