"We have been highly encouraged by the responses observed in the Phase I/Ib study of MT-3724 in heavily pretreated DLBCL patients," said Eric Poma, Ph.D., CEO and CSO of Molecular Templates. "This Phase II study largely replicates the Phase Ib expansion cohort, but with more clinical sites for enrollment, an independent data safety monitoring board, and independent central review for efficacy. Given the high level of unmet need in advanced DLBCL, we hope that this study will confirm that MT-3724 provides a meaningful benefit for this difficult to treat patient population."

The Phase II study will initially enroll patients at sites in the United States, Canada and Europe. MT-3724 will be given as 50 mcg/kg intravenous (IV) infusions, with a maximal per dose limit of 6,000 mcg. The primary outcome measure is tumor response, while secondary objectives include safety and other efficacy measures. The Phase II dose of 50 mcg/kg was selected based on safety data, tumor responses observed at dose levels as low as 5 and 20 mcg/kg, and pharmacodynamic effects of CD20+ B-cell clearance observed at various doses in the Phase I/Ib study. The Phase II study will exclude patients with high levels of serum rituximab, given CD20 binding competition of rituximab with MT-3724.

"Our ultimate goal at Forty Seven is to enable more patients to defeat their cancers by delivering a new class of therapies, which take advantage of the innate immune system as a powerful therapeutic target," said Mark McCamish, M.D., Ph.D., President and Chief Executive Officer of Forty Seven, Inc. "In 2018, we made important strides toward achieving this goal, announcing proof-of-concept data for 5F9 in a range of difficult-to-treat cancers and demonstrating its best-in-class safety profile, which is enabled by our proprietary priming and maintenance dosing regimen. In addition, we expanded our pipeline with FSI-189 and FSI-174, reinforced our intellectual property portfolio, and strengthened our corporate position, hiring Ann Rhoads as Chief Financial Officer, adding Kristine Ball and Ian Clark to our Board of Directors, creating a world-class Scientific Advisory Board and successfully completing our initial public offering.

Dr. McCamish continued, "As we move into 2019, we are building on this forward momentum, with a particular focus on executing our clinical plans. We expect to generate meaningful data across multiple programs this year, beginning with updated clinical data from our Phase 1b/2 trial of 5F9 plus rituximab in r/r NHL and our Phase 1b trial of 5F9 as a monotherapy and in combination with azacitidine in AML and MDS, all expected in the second quarter. We are also advancing four additional trials with 5F9 and expect to provide updated data in ovarian and colorectal cancer in the fourth quarter, while conducting investigational new drug-application enabling studies for FSI-189, an anti-SIRPα antibody, and FSI-174, an anti-cKIT antibody."

Fourth Quarter and Recent Business Highlights:

Pipeline:

In January 2019, Forty Seven announced FSI-174, an anti-cKIT antibody, as its third development candidate. Forty Seven plans to develop FSI-174 in combination with anti-CD47 antibodies as a non-toxic transplant conditioning regimen, as well as a treatment for targeted hematologic malignancies.

In December 2018, Forty Seven presented preclinical data at the 60th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting, providing additional mechanistic insight into why its proprietary 5F9 priming and maintenance dosing strategy mitigates the on-target anemia caused by the clearance of aged red blood cells (RBCs). The data show that the initial priming dose of 5F9 results in a near complete loss of CD47 on surviving, younger RBCs, making these cells less susceptible to phagocytosis and decreasing the risk of CD47 antibody-induced anemia during subsequent maintenance dosing.

Helping Patients Defeat Their Cancer

Also at ASH (Free ASH Whitepaper), Forty Seven presented new preclinical data supporting the development of 5F9 and azacitidine for the treatment of AML. The data show that the combination of 5F9 and azacitidine increases the phagocytic elimination of AML blast cells by human macrophages in vitro, enhances clearance of AML in vivo, and prolongs survival compared to single-agent treatment with either 5F9 or azacitidine alone.

In November 2018, Forty Seven announced that proof-of-concept data from the Phase 1b portion of its Phase 1b/2 clinical trial evaluating 5F9 in combination with rituximab in patients with r/r NHL were published in the New England Journal of Medicine.

Key Upcoming Milestones:

The company expects to achieve the following milestones by the end of 2019:

Report data from the Phase 1b/2 trial of 5F9 in combination with rituximab in patients with r/r NHL, including safety, efficacy and duration of response across various dosing cohorts, in the second quarter.

Report data from the Phase 1b trial of 5F9 as a monotherapy and in combination with azacitidine in patients with AML and MDS, including safety and initial efficacy data, in the second quarter.

Report data from the Phase 1b trial of 5F9 in combination with avelumab in patients with ovarian cancer in the fourth quarter.

Report data from the Phase 1b trial of 5F9 in combination with cetuximab in patients with colorectal cancer in the fourth quarter.

Report preclinical data and complete IND-enabling studies for FSI-174 in the second half.

Completing IND-enabling studies for FSI-189 in the second half.

Fourth Quarter and Full Year 2018 Financial Results:

Cash Position: As of December 31, 2018, cash, cash equivalents and short-term investments were $139.0 million, as compared to $88.1 million as of December 31, 2017. This increase reflects net proceeds of $116.3 million from Forty Seven’s initial public offering of common stock, which closed in July 2018. The company expects that its cash, cash equivalents and short-term investments will fund operating expenses and capital expenditure requirements through the first half of 2020.

R&D Expenses: R&D expenses were $13.9 million for the fourth quarter of 2018 and $56.7 million for the full year ended December 31, 2018, as compared to $10.0 million for the fourth quarter of 2017 and $37.2 million for the full year ended December 31, 2017. This increase was primarily due to an increase in third party costs associated with the continued advancement of the company’s clinical development efforts, an increase in personnel-related costs, including stock-based compensation, and non-recurring upfront payments of $8.8 million associated with two licensing deals. This increase was partially offset by $5.3 million in grant funding and cost sharing from the California Institute of Regenerative Medicine, the Leukemia and Lymphoma Society, and Merck KGaA.

G&A Expenses: G&A expenses were $3.8 million for the fourth quarter of 2018 and $15.4 million for the full year ended December 31, 2018, as compared to $2.6 million for the fourth quarter of 2017 and $8.1 million for the full year ended December 31, 2017. This increase was primarily due to an increase in personnel-related costs and expenses incurred in connection with operating as a public company.

Net Loss: Net loss was $17.2 million for the fourth quarter of 2018 and $70.4 million for the full year ended December 31, 2018, or a net loss per share of $0.56 and $3.75, respectively, as compared to $12.3 million for the fourth quarter of 2017 and $44.9 million for the full year ended December 31, 2017, or a net loss per share of $1.88 and $6.94, respectively.

Preclinical studies showed that OBI-888’s mechanism of action involves antibody-induced tumor lysis which may have substantial therapeutic potential. OBI-888 is currently in a Phase 1 clinical study in solid tumor patients at the MD Anderson Cancer Center in Houston, Texas (USA). For OBI-999, preliminary pharmacological studies in established animal tumor models showed potent and long lasting anti-tumor activity in multiple cancer types, including breast, pancreatic, lung and gastric cancer. A US FDA IND submission is planned for 2019. OBI Pharma owns global rights to OBI-888 and OBI-999.

About OBI-888

OBI-888 is a novel first-in-class monoclonal antibody, which selectively targets Globo H, an antigen expressed in up to 15 types of epithelial cancer. This Globo H targeting antibody has been shown to induce tumor-killing via antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cell-mediated phagocytosis (ADCP) and complement-dependent cytotoxicity (CDC).

OBI-888 is also anti-immunosuppressive and anti-angiogenic. In pre-clinical xenograft animal models in multiple tumor types (pancreatic, colon, lung, and breast), OBI-888 has demonstrated tumor shrinkage at various doses. In pre-clinical single and repeated dose toxicology studies, OBI-888 was well-tolerated with no adverse effects observed in all the doses tested.

About OBI-999

OBI-999 is an antibody-drug conjugate (ADC) treatment for cancer. OBI-999 uses a Globo H antibody to target cancer cells of high Globo H expression. By releasing a small molecule chemotherapeutic drug through the specificity of the antibody, it directly deploys cytotoxic therapy at the targeted cancer cells. Preliminary pharmacological studies and animal verification have already been completed and showed impressive and long lasting anti-tumor efficacy in multiple cancer types, including breast, pancreatic, lung and gastric cancer. It is currently undergoing Chemistry Manufacturing Control (CMC) planning and toxicology study design.
