TCR² Therapeutics Reports Fourth Quarter and Full Year 2018 Financial Results and Provides Corporate Update

Apr 01, 2019
- U.S. Food and Drug Administration (FDA) cleared TCR2's investigational new drug (IND) application for its lead solid tumor candidate TC-210; Company initiated Phase 1/2 clinical trial
- Initial public offering completed in February raised approximately $80.2 million in net proceeds
- Held pre-IND meeting with FDA for lead hematology candidate TC-110
- Patent issued with claims covering TCR2's TRuC™-T cells that express anti-mesothelin T cell receptor fusion proteins including TC-210

CAMBRIDGE, Mass., April 1, 2019 /PRNewswire/ -- TCRTherapeutics Inc. (Nasdaq: TCRR), a clinical-stage immunotherapy company developing the next generation of novel T cell therapies for patients suffering from cancer, today reported financial results for the fourth quarter and full year ended December 31, 2018 and provided a corporate update.

"TCR2 has achieved important scientific, clinical, and operational milestones over the past year," said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR2 Therapeutics. "Although adoptive T cell therapies have made significant progress in the fight against cancer, our TRuC platform has the potential to both improve upon existing options and expand their use. TC-210 has cleared its IND and we have initiated our Phase 1/2 clinical trial, with initial data expected later this year. We also remain on track to submit an IND for TC-110 in the second half of 2019. In February, we successfully completed our initial public offering, a significant step for the Company which further strengthened our financial position."

2018 Corporate Highlights

  • Advanced TC-210, TCR2's lead T cell receptor (TCR) Fusion Construct T cell (TRuC™ T cell) product candidate, to investigational new drug (IND) application submission in December 2018 and IND clearance by the U.S. Food and Drug Administration (FDA) in January 2019. TCR2 engineered TC-210 T cells to target and kill mesothelin-expressing cancers while engaging the entire TCR, independent of human leukocyte antigens (HLA). In preclinical studies, TC-210 has demonstrated better anti-tumor activity, longer persistence, and lower cytokine release compared to chimeric antigen receptor (CAR)-T cells engineered with the same mesothelin binder. TCR2 initiated a Phase 1/2 clinical trial for TC-210 to treat patients with mesothelin-positive solid tumors, including non-small cell lung cancer (NSCLC), ovarian cancer, malignant pleural/peritoneal mesothelioma, and cholangiocarcinoma. TCR2 expects to generate its first clinical data for TC-210 in the second half of 2019.
  • Expanded the TCR2 pipeline, initiating IND-enabling studies for TC-110 and TC-220 product candidates, and building next-generation enhancements into the TRuC platform.
    • TC-110 is a CD19 targeted TRuC-T cell product candidate designed to treat patients with CD19-positive B-cell hematological malignancies, including diffuse large B-cell lymphoma (DLBCL), adult acute lymphoblastic leukemia (aALL), follicular lymphoma (FL), and other non-Hodgkin lymphoma (NHL) subtypes. In preclinical studies, TC-110 has shown better anti-tumor activity and persistence compared to CD28 and 4-1BB CAR-T cells engineered with the same CD19 binder, while also exhibiting lower levels of cytokine release.
    • TC-220 is a MUC16 (Mucin 16, Cell Surface Associated)-targeted TRuC-T cell product candidate designed to treat patients with MUC16-positive solid tumors. MUC16 is highly expressed in many solid tumors, including ovarian, pancreatic, gastric, and colorectal cancers. TC-220 has shown strong anti-tumor activity in preclinical models of MUC16-positive ovarian cancers. TCR2 plans to file an IND for TC-220 in the first half of 2020.
    • TCR2 is developing several additional tools that may be incorporated into future TRuC product candidates to overcome tumor defense mechanisms, including dual-antigen targeting and strategies to counter the immunosuppressive microenvironment of solid tumors. TCR2 is also evaluating multiple proprietary designs for allogeneic, or off the shelf, TRuC-T cells.
  • Established semi-automated Good Manufacturing Practice (GMP) manufacturing process. TCR2 currently manufactures GMP-grade clinical lots for TC-210 through third-party contractors. In December 2018, TCR2 entered into an agreement with Cell and Gene Therapy (CGT) Catapult Limited (Catapult), which will allow TCR2 to manufacture TRuC-T cells using its own personnel at CGT Catapult's facility in Stevenage, UK. The TCR2 CGT Catapult facility is expected to be operational in the second half of 2019. At full capacity, TCR2 estimates this facility would expand its manufacturing capacity to a total of approximately 400 treatments per year.
  • Raised $125 million in an oversubscribed Series B financing round in March 2018. The financing was co-led by 6 Dimensions Capital and Curative Ventures with participation from new investors Redmile and Arrowmark and all of TCR2's Series A investors.
  • Strengthened its management and board in 2018. This included adding Ian Somaiya as Chief Financial Officer, along with Neil Gibson Ph.D. and Andrew Allen M.D., Ph.D. to the Board of Directors.

Recent Developments

  • In January 2019, the FDA cleared the IND for TC-210. TCR2 initiated its Phase 1/2 trial to treat patients with NSCLC, ovarian cancer, malignant pleural/peritoneal mesothelioma, and cholangiocarcinoma. TCR2 expects to generate initial data from the trial in the second half of 2019.
  • In February 2019, TCR2 completed an initial public offering pursuant to which it issued and sold 5,750,000 shares of common stock, including full exercise of the underwriters' over-allotment option, resulting in net proceeds of $80.2 million after deducting underwriting discounts and commissions and other offering expenses.
  • In February 2019, the FDA granted orphan drug designation to TC-210 for the treatment of mesothelioma.
  • TCR2 recently held a pre-IND meeting with the FDA and remains on track to submit an IND for TC-110 in the second half of 2019.
  • In February 2019, the United States Patent and Trademark Office issued U.S. Patent No.: 10,208,285, with claims covering TCR2's TRuC-T cells that express anti-mesothelin TCR fusion proteins, including TC-210.

Anticipated Milestones

TCR2 plans to advance its first three TRuC-T cell product candidates into clinical trials by the first half of 2020, while also establishing and expanding its manufacturing capabilities through its collaboration with CGT Catapult.

  • TC-210 - release initial Phase 1 data from the Phase 1/2 trial in 2H 2019.
  • TC-110 - IND submission in 2H 2019.
  • TC-220 - IND submission in 1H 2020.
  • Catapult manufacturing facility - operational in 2H 2019.

Financial Highlights

  • TCR2 ended 2018 with $123.2 million in cash, cash equivalents, and investments compared to $19.8 million as of December 31, 2017. Net cash from financing activities for the year ended December 31, 2018 was $123.0 million compared to $16.2 for the year ended December 31, 2017. Net cash used in operations was $18.8 million for the year ended December 31, 2018 compared to $12.0 million for the year ended December 31, 2017.
  • Net loss for the year ended December 31, 2018 was $24.3 million compared to $13.1 million for the year ended December 31, 2017.
  • Research and development expenses were $19.7 million for the year ended December 31, 2018 compared to $9.6 million for the year ended December 31, 2017. The increase in R&D expenses is primarily related to increase in headcount and preclinical development of our lead solid tumor product candidate, TC-210.
  • General and administrative expenses were $6.8 million for the year ended December 31, 2018, compared to $3.6 million for the year ended December 31, 2017. The increase in general and administrative expenses was primarily due to an increase in personnel costs.
