On March 28, 2018 Molecular Templates, Inc. (Nasdaq:MTEM) ("Molecular"), a clinical-stage oncology company focused on the discovery and development of the company’s proprietary engineered toxin bodies (ETBs), which are differentiated, targeted, biologic therapeutics for cancer, reported financial results for the fourth quarter of 2017. As of December 31, 2017, cash and cash equivalents totaled $58.9 million (Press release, Molecular Templates, MAR 28, 2018, View Source [SID1234525039]). Molecular’s current cash balance is expected to fund operations into late 2019.

"We are excited by the continued progress of our pipeline as well as our partnership with Takeda," said Eric Poma, Ph.D., CEO and CSO of Molecular Templates. "We expect the remainder of 2018 to bring more data on our lead program MT-3724 in DLBCL, additional IND filings for other pipeline programs, and the potential for more business development transactions that would support additional programs with non-dilutive capital."
Company Highlights and Upcoming Milestones
Corporate
In 4Q17, Molecular expanded its senior management team with the additions of Adam Cutler as Chief Financial Officer; Barbara Ruskin J.D. Ph.D. as SVP, General Counsel and Chief Patent Officer; Nenad Sarapa M.D. M.S. as SVP of Clinical Development, and Conrad Jordaan as SVP of Finance and Corporate Controller.
On March 2, 2018, Molecular closed a $10 million debt facility with Perceptive Advisors. The proceeds were used to repay an existing debt facility with Silicon Valley Bank and will support Molecular’s build out of its GMP manufacturing facility, which should shorten the time from lead development to IND and better support Molecular’s own pipeline as well as partnerships.
MT-3724
MT-3724 (an ETB targeting CD20) is in an ongoing Phase Ib expansion study intended to better define the overall response rate to this candidate as a single-agent in heavily pre-treated diffuse large B-cell lymphoma (DLBCL) patients.
A brief update on the first three patients dosed in the MT-3724 Phase Ib expansion study was delivered at the World ADC Summit Europe today. Observations included the following:
One of the three patients achieved a partial response (PR) after a single dose of MT-3724. The PR was confirmed at the end of cycle 2 per protocol and the patient remains on study with continued dosing of MT-3724. The other two patients were assessed as having stable disease (SD) and progressive disease (PD).
A dose interruption and reduction was required in two of the first three patients in Phase Ib expansion. These patients had high body weights which resulted in high absolute doses of MT-3724 based on 75 mcg/kg dosing. The adverse events observed (grade 2 and 3) were reversible and dosing resumed at 50 mcg/kg, which has been generally well tolerated.
Based on these data, the deep and sustained clinical responses to MT-3724 observed at doses as low as 5 mcg/kg, as well as the near-complete peripheral B-cell depletion at doses up to 50 mcg/kg, the maximum tolerated dose (MTD) of MT-3724, has been defined as 50 mcg/kg with a maximum total drug per dose of 6,000 mcg, or 6 mg.
Enrollment in the Phase Ib expansion study continues, with further updates on results expected in 2Q18.
Nine DLBCL patients with low serum levels of rituximab have been treated at doses ranging from 5 mcg/kg to 75 mcg/kg in the Phase I dose-finding and Phase Ib expansion studies. In these nine patients, one complete response, two partial responses, three patients with stable disease (including one patient with a 48% reduction in tumor size), and three patients with progressive disease, were observed.
Based on the peripheral B-cell depletion observed at 50 mcg/kg and responses seen at doses as low as 5 mcg/kg, 50 mcg/kg appears to be an efficacious and well-tolerated dose.
Molecular also expects to initiate combination studies with MT-3724 in earlier lines of DLBCL therapy in 2Q18.
Takeda Collaboration
In December 2017, Takeda selected two targets for further research using Molecular’s ETBs. This has triggered $4 million in milestone payments to be paid by Takeda in 2018.
Takeda and Molecular are evaluating CD38 ETBs and could select a drug candidate for development by the end of 2Q18.
MT-4019
MT-4019, an ETB candidate that is designed to target CD38-expressing myeloma cancer cells, is progressing through IND enabling studies. If Takeda and Molecular do not select a joint candidate for development, Molecular anticipates filing an IND application for MT-4019 in mid-2018 to initiate a Phase I clinical trial in the United States in 2H18.
Research
Preclinical data for Molecular’s ETBs targeting PD-L1 (which incorporates Molecular’s Antigen Seeding Technology – a differentiated immune-oncology approach) and HER2 will be presented at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) annual meeting in April 2018
Molecular expects to file an IND application for an ETB targeting HER2 in 4Q18
Molecular expects to file an IND application for an ETB targeting PD-L1 (with antigen seeding) in 1Q19
Several other ETB candidates are in preclinical development targeting both solid and hematological cancers
Financial Results
The net loss attributable to common shareholders for the fourth quarter was $6.9 million, or $0.26 per basic and diluted share. This is compared to a net loss attributable to common shareholders for the same period in 2016, of $2.9 million, or $13.82 per basic and diluted share.
Revenues for the fourth quarter of 2017 were $0.8 million, compared to $0.4 million for the same period in 2016. Revenues in the fourth quarters of 2017 and 2016 were comprised of grant revenue from the Cancer Prevention & Research Institute of Texas ("CPRIT"). Total research and development (R&D) expenses for the fourth quarter of 2017 were $4.7 million, compared with $1.7 million for the same period in 2016. Total general and administrative (G&A) expenses for the fourth quarter of 2017 were $3.5 million, compared with $1.1 million for the same period in 2016.
Revenues for the year ended December 31, 2017 were $3.4 million, compared to $1.9 million for 2016. These revenues were primarily comprised of research and development revenues from our collaboration with Takeda of $1.9 million, and grant revenue from CPRIT of $1.0 million. Revenues for the same period in 2016 comprised of grant revenue from CPRIT. Total R&D expenses for the year ended December 31, 2017 were $9.5 million, compared to $8.0 million for 2016. Total G&A expenses for the year ended December 31, 2017 were $11.8 million, compared to $4.5 million for 2016.
The net loss attributable to common shareholders for the year ended December 31, 2017 was $24.1 million, or $2.11 per basic and diluted share, compared to a net loss attributable to common shareholders of $12.6 million or $59.04 per basic and diluted share, for 2016. As of December 31, 2017, cash and cash equivalents totaled $58.9 million. Molecular’s current cash balance is expected to fund operations into late 2019.
