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

CAMBRIDGE, Mass., April 1, 2019 /PRNewswire/ -- TCR(2) Therapeutics 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.

"TCR(2 )has achieved important scientific, clinical, and operational milestones over the past year," said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR(2) 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, TCR(2)'s lead T cell receptor (TCR) Fusion Construct T
        cell (TRuC(TM) 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. TCR(2)
        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. TCR(2) 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. TCR(2) expects
        to generate its first clinical data for TC-210 in the second half of
        2019.
    --  Expanded the TCR(2) 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. TCR(2) plans to file an
            IND for TC-220 in the first half of 2020.
        --  TCR(2 )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.
            TCR(2) is also evaluating multiple proprietary designs for
            allogeneic, or off the shelf, TRuC-T cells.
    --  Established semi-automated Good Manufacturing Practice (GMP)
        manufacturing process. TCR(2) currently manufactures GMP-grade clinical
        lots for TC-210 through third-party contractors. In December 2018,
        TCR(2) entered into an agreement with Cell and Gene Therapy (CGT)
        Catapult Limited (Catapult), which will allow TCR(2) to manufacture
        TRuC-T cells using its own personnel at CGT Catapult's facility in
        Stevenage, UK. The TCR(2) CGT Catapult facility is expected to be
        operational in the second half of 2019. At full capacity, TCR(2)
        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 TCR(2)'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. TCR(2) initiated
        its Phase 1/2 trial to treat patients with NSCLC, ovarian cancer,
        malignant pleural/peritoneal mesothelioma, and cholangiocarcinoma.
        TCR(2) expects to generate initial data from the trial in the second
        half of 2019.
    --  In February 2019, TCR(2) 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.
    --  TCR(2) 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 TCR(2)'s TRuC-T cells
        that express anti-mesothelin TCR fusion proteins, including TC-210.

Anticipated Milestones

TCR(2 )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

    --  TCR(2) 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.
