Unum Therapeutics Reports Third Quarter 2019 Financial Results

965 Days ago

- Progress towards focusing on solid tumors remains on track with enrollment and early safety updates from Phase 1 trial of ACTR707 in HER2+ cancers expected by the end of this year-

CAMBRIDGE, Mass., Nov. 12, 2019 (GLOBE NEWSWIRE) -- Unum Therapeutics Inc. (NASDAQ: UMRX), a clinical-stage biopharmaceutical company focused on developing curative cell therapies for cancer, today reported financial results and corporate updates for the third quarter ended September 30, 2019, and provided recent activities.

“Our recently announced strategic focus towards addressing the challenge of treating solid tumor cancers is well underway with ACTR707, BOXR1030, and our BOXR platform that is designed to discover new product candidates aimed at improving the function of T cell therapies in the solid tumor microenvironment,” said Chuck Wilson Ph.D., President and Chief Executive Officer of Unum. “BOXR1030, which co-expresses the GOT2 transgene and is designed to improve T cell metabolism and reduce T cell exhaustion, generated complete tumor regressions under metabolically challenging conditions in preclinical studies as presented at the SITC meeting.  For ACTR707, our Phase 1 trial is progressing nicely and we remain on track to report enrollment and early safety updates from patients treated in the first dose cohort by the end of this year.”

Recent Program and Corporate Highlights

  • Announced strategic focus on developing best-in-class cellular therapies for solid tumor cancers: Unum is uniquely positioned to address the challenge of treating solid tumor cancers with its two platforms—ACTR and BOXR—having recently validated ACTR in the hematologic setting and with preclinical data recently emerging from BOXR1030, the first product candidate from BOXR. Unum’s ACTR platform enables selective T cell targeting for on-tumor attack while its BOXR platform is designed to improve T cell functionality in the solid tumor microenvironment (TME) through the co-expression of novel transgenes. Unum’s priorities in solid tumors include: 1) completing the ongoing ATTCK-34-01 Phase 1 trial of ACTR707 in HER2+ cancers, 2) advancing BOXR1030 towards the clinic with an anticipated IND filing in late 2020; and 3) expanding its BOXR platform to accelerate discovery of new product candidates across a broad range of immune cell therapies, including both autologous and allogeneic approaches. Five clinical trial sites are activated and Unum expects to report preliminary safety data from patients treated in the first dose cohort of the Phase 1 ATTCK-34-01 trial of ACTR707 combined with trastuzumab to treat advanced HER2+ solid tumor cancers by the end of this year, and to report safety and clinical response data from multiple dose cohorts in 2020.
  • Presented preclinical data for BOXR1030 at the Society for Immunotherapy of Cancer (SITC) Annual Meeting (November 6-10): BOXR1030 expresses a glypican-3 (GPC3) targeted chimeric antigen receptor (CAR) with the addition of the “bolt-on” transgene glutamic-oxaloacetic transaminase 2 (GOT2) to improve T cell function in the TME by enhancing T cell metabolism. As presented at the SITC conference, expression of the GOT2 mitochondrial enzyme in BOXR1030 increased the production of key amino acids and metabolites, improved the anti-oxidant balance of T cells, and prevented their dysfunction and exhaustion in preclinical studies using stringent animal xenograft models that simulate the TME. In vitro, BOXR1030 T cells were resistant to suppressive TME-like conditions, showing improved T cell proliferation under both hypoxic and low glucose conditions compared with control GPC3+ CAR-T cells. In vivo, BOXR1030 demonstrated superior activity compared to the control CAR-T with treated animals achieving complete tumor regressions under metabolically challenging conditions. Tumor infiltrating lymphocytes isolated from the tumors of treated animals revealed that BOXR1030 cells were more resistant to dysfunction, had fewer markers of exhaustion, and remained functional as compared to the control CAR-T cells.
  • Announced de-prioritized investment in hematologic programs. The clinical response and tolerability data recently generated from the ATTCK-20-03 Phase 1 trial in non-Hodgkin lymphoma established proof-of-concept for ACTR707, allowing the company to focus its efforts towards the ATTCK-34-01 Phase 1 trial in solid tumors, a clinical setting for which ACTR707 was originally developed. With favorable tolerability at relatively low doses explored to date, Unum announced plans to continue limited dose escalation to inform potential future development of the program in 2020.

Separately, Unum and its partner, Seattle Genetics, Inc., have suspended further dose-escalation of the ATTCK-17-01 Phase 1 trial of ACTR087 with SEA-BCMA in multiple myeloma pending a further review of this program. Two additional cohorts of patients have been treated in the Phase 1 trial in 2019, escalating doses of the SEA-BCMA antibody to 2.0 mg/kg and of the ACTR087+ T cells to 50M. No dose-limiting toxicities (DLTs) following ACTR087 administration were reported and no severe adverse events of cytokine release syndrome (CRS) or neurologic events have been observed to date.

  • Announced accepted oral and poster presentations at upcoming American Society of Hematology (ASH) Annual Meeting, December 7-10, Orlando, FL.

    • Title: “A Phase 1 Study of ACTR087 in Combination with Rituximab, in Subjects with Relapsed or Refractory CD20-Positive B-Cell Lymphoma
      Presenting Author: Javier Munoz, M.D., M.S., Banner MD Anderson Cancer Center, Gilbert AZ

Third Quarter 2019 Financial Results

  • Collaboration Revenue : Collaboration revenue recognized during the third quarter ended September 30, 2019 was $1.0 million, compared to $2.0 million in the same period of 2018. Collaboration revenue, which includes the recognition of a portion of the upfront payment received from Seattle Genetics, Inc. as well as reimbursements of research and development costs attributed to the Seattle Genetics, Inc. collaboration agreement, decreased as a result of fewer activities related to the programs under the collaboration agreement.
  • R&D Expenses: Research and development expenses were $10.3 million for the third quarter ended September 30, 2019 compared to $10.3 million for the same period of 2018. Research and development expenses relate to costs for the ongoing Phase 1 trials and preclinical programs, as well as personnel-related costs to support these programs.
  • G&A Expenses:  General and administrative expenses for the third quarter ended September 30, 2019 were $2.7 million, compared to $2.4 million for the same period of 2018. The increase is primarily related to increased headcount and personnel-related costs as well as expenses required to operate as a public company.
  • Net Loss: Net loss attributable to common stockholders was $12.0 million, or $0.39 per share, for the third quarter ended September 30, 2019 compared with a net loss attributable to common stockholders of $10.2 million, or $0.34 per share, for the same period of 2018.
  • Cash and Cash Equivalents: As of September 30, 2019, Unum had cash and cash equivalents of $45.9 million. Unum believes that its existing cash and cash equivalents will fund operating expenses and capital expenditure requirements into early 2021.
