TTI-621 is an antibody-like fusion protein that blocks the inhibitory activity of CD47, a molecule that is overexpressed by a wide variety of tumors. CD47 binds to SIRPa on macrophages and delivers a "do not eat" signal that inhibits the ability of macrophages to engulf and destroy cancer cells. Preclinical studies have shown that TTI-621 has anti-tumor activity across a range of hematologic tumors.

"This is an exciting time for Trillium as we now emerge as a clinical stage oncology company evaluating a novel immune checkpoint inhibitor," commented Dr. Eric Sievers, Trillium’s Chief Medical Officer. "At a fundamental level, a cancer patient’s ineffective immune response allows the tumor to propagate unchecked. By blocking CD47, a key cell-surface protein that inhibits phagocytosis, we hope to summon a durable anti-tumor response in patients who are beset by cancer."

The two-part clinical trial is designed as a multi-center, open-label Phase 1a/1b trial, evaluating TTI-621 as a single-agent in patients with relapsed or refractory hematologic malignancies. During the dose escalation phase set to enroll up to 36 subjects, the safety, tolerability, pharmacokinetics and pharmacodynamics will be characterized to determine the optimal dose for subsequent enrollment in the expansion phase. In this second part of the trial, the safety and preliminary antitumor activity of TTI-621 at the optimal dose identified in the escalation phase will be explored in 12-15 subjects per hematologic malignancy type: indolent B-cell lymphoma, aggressive B-cell lymphoma, T-cell lymphoma, Hodgkin lymphoma, chronic lymphocytic leukemia, multiple myeloma, acute myeloid leukemia, and myelodysplastic syndrome.

Trillium has proposed five trial sites including the Mayo Clinic, Columbia University Medical Center, City of Hope National Medical Center, The Colorado Blood Cancer Institute, and Tennessee Oncology.

Second Quarter Fiscal 2016 Results

Total revenues for the second quarter of fiscal year 2016, which ended on December 31, 2015, were $0.7 million, as compared to total revenues of $1.0 million for the same quarter last fiscal year. The decrease of $0.3 million in total revenues this quarter was primarily the result of $0.2 million lower LeukoScan product sales, due equally to unfavorable currency fluctuations and lower sales volume in Europe, and a $0.1 million decline in research and development revenues from fewer number of government funded research grants.

Total costs and expenses for the current quarter were $16.4 million, as compared to $12.5 million for the same period in 2014, representing an increase of $3.9 million or 31%. This increase was driven primarily by $3.9 million increased research and development expenses from higher product development expenses related to the Phase 3 PANCRIT-1 registration study of yttrium-90-labeled clivatuzumab tetraxetan for the therapy of patients with advanced pancreatic cancer and the Phase 2 antibody-drug conjugates’ clinical trials. The increase in research and development expenses was partially offset by a $0.2 million lowered legal and professional expenses, principally related to the arbitration proceedings with Takeda-Nycomed, which concluded during the 2015 fiscal year.

Interest expense this quarter related to the 4.75% Convertible Senior Notes due 2020 was $1.4 million, which included the amortization of $0.2 million debt issuance costs. There was no interest expense for the same quarter last fiscal year.

An income tax benefit of $3.2 million was recorded during the current quarter, the result of cash proceeds received for the sale of a portion of our New Jersey State tax net operating losses and research and development tax credits. There were no similar tax benefits during the previous quarter.

Net loss attributable to our stockholders this quarter was $13.7 million, or $0.15 per share, compared with a net loss attributable to our stockholders of $11.4 million, or $0.12 per share, for the same quarter in fiscal 2015. The $2.3 million increase in net loss this quarter was primarily due to the increase in research and development expenses and interest expense for the Convertible Senior Notes, which was partially offset by the $3.2 million tax benefits received.

First Half Fiscal 2016 Results

For the first half of fiscal year 2016, total revenues were $1.4 million, as compared to total revenues of $2.1 million for the same period last fiscal year. The decrease of $0.7 million in total revenues was primarily due to a $0.4 million reduction in research and development revenue from a decline in the number of government funded research grants and $0.3 million lowered LeukoScan sales, due to unfavorable currency fluctuations and lower sales volume in Europe.

Total costs and expenses for the six-month period ended December 31, 2015 were $31.2 million, as compared to $26.0 million for the same period in 2014, representing an increase of $5.2 million or 20%. This increase was driven primarily by $7.4 million higher research and development expenses for product development expenses related to the Phase 3 PANCRIT-1 and the Phase 2 antibody-drug conjugates’ clinical trials. The increase in research and development expenses this period was partially offset by the $2.4 million decrease in general and administrative expenses attributable primarily to reduced legal and professional fees related to the arbitration proceedings with Takeda-Nycomed.

Interest expense this period related to the 4.75% Convertible Senior Notes was $2.8 million and included the amortization of $0.4 million debt issuance costs. There was no interest expense for the same period last fiscal year.

An income tax benefit of $3.2 million was recorded for the current period, the result of cash proceeds received for the sale of a portion of our New Jersey State tax net operating losses and research and development tax credits. No tax benefits were received during the previous period.

Net loss attributable to our stockholders this period was $29.1 million, or $0.31 per share. This compares to net loss attributable to our stockholders of $23.8 million, or $0.26 per share, for the same period last fiscal year. The $5.3 million increase in net loss this period was primarily due to increased research and development costs related to clinical trials and interest expense for the Convertible Senior Notes, partially offset by the income tax benefits received and lower legal and professional fees, as described above.

As of December 31, 2015, cash, cash equivalents and marketable securities totaled $76.0 million. On January 21, 2016, the Company received another $1.9 million in proceeds as a result of a second sale of our New Jersey State net operating losses and research and development tax credits.

"The $5.1 million total cash proceeds that the Company received from the State of New Jersey’s Technology Business Tax Certificate Transfer Program has allowed us to continue to advance our key clinical programs according to plan, as exemplified by the recent Special Protocol Assessment for a future Phase 3 trial for sacituzumab govitecan in patients with triple-negative breast cancer," commented Peter P. Pfreundschuh, Vice President Finance and Chief Financial Officer. "We are pleased with the current enrollment into the ongoing pivotal Phase 3 PANCRIT-1 study in patients with advanced pancreatic cancer, which is expected to complete enrollment this calendar year," added Mr. Pfreundschuh.

The Company’s key clinical developments and future planned activities:

Sacituzumab Govitecan (IMMU-132)

The Company has reached agreement with the U.S. Food and Drug Administration regarding a Special Protocol Assessment (SPA) on the design of a Phase 3 trial of sacituzumab govitecan for the treatment of patients with metastatic triple-negative breast cancer.

Improved progression-free survival (PFS) with an interim median PFS of 7.0 months was reported at the 2015 AACR (Free AACR Whitepaper)-NCI-EORTC Molecular Targets and Cancer Therapeutics Conference in patients with triple-negative breast cancer (TNBC) treated with sacituzumab govitecan.

The abstract, titled "PV-10 Induces Potent Immunogenic Apoptosis in Colon Cancer Cells," was presented by N. M. Kunda of the University of Illinois at Chicago, Division of Surgical Oncology, Department of Surgery, College of Medicine, Chicago, IL, USA. The research team is led by Dr. A.V. Maker, and co-authors in addition to Drs. Kunda and Maker are: J. Qin, G. Qiao also of UIC, Division of Surgical Oncology, Department of Surgery. The team of authors also includes B. Prabhakarof the University of Illinois at Chicago, Department of Microbiology & Immunology, College of Medicine, Chicago, IL, USA. Dr. Maker belongs to both Departments.

In the presentation, Dr. Kunda noted that in vitro testing of PV-10 on colon cancer (murine CT-26 cells) showed cytotoxicity consistent with immunogenic apoptosis. Further, he stated that the researchers observed cell arrest, apoptosis, autophagy and endoplasmic reticulum (ER) stress. He concluded that these results are consistent with immunologic cell death caused by PV-10.

Dr. Eric Wachter, CTO of Provectus, said, "The work reported in Dr. Kunda’s presentation further expands our understanding of the mechanism of action of PV-10 as an ablative immunotherapy for solid tumors, and parallels immunologic signaling noted upon ablation of melanoma with PV-10."

TapImmune Granted Fast Track Designation by U.S. Food & Drug Administration for its Lead Vaccine TPIV 200 in the Treatment of Ovarian Cancer

On February 3, 2016 TapImmune, Inc. (TPIV), a clinical-stage immuno-oncology company specializing in the development of innovative peptide and gene-based immunotherapeutics and vaccines for the treatment of cancer & metastatic disease, reported that the U.S. Food & Drug Administration (FDA) has granted Fast Track Designation for its cancer vaccine TPIV 200 in the treatment of ovarian cancer (Press release, TapImmune, FEB 3, 2016, View Source;drug-administration-for-its-lead-vaccine-tpiv-200-in-the-treatment-of-ovarian-cancer-567496381.html [SID:1234508964]).

The FDA has designated the investigation of multiple-epitope Folate Receptor Alpha Peptide Vaccine (TPIV 200) with GM-CSF adjuvant for maintenance therapy in subjects with platinum-sensitive advanced ovarian cancer who achieved stable disease or partial response following completion of standard of care chemotherapy, as a Fast Track Development Program.

Under the FDA Modernization Act of 1997, designation as a Fast Track product for a new drug or biological product means that the FDA will take such actions as are appropriate to expedite the development and review of the application for approval of such product.

"We believe that the FDA’s decision to grant Fast Track designation to TPIV 200 for the treatment ovarian cancer significantly expedites our clinical development program. We look forward to starting Phase II trials in the near future to address this highly aggressive cancer", commented Dr. Glynn Wilson Chairman & CEO of TapImmune. "We believe that TPIV 200 has the potential to improve outcomes for ovarian cancer patients for whom current treatment modalities offer a relative short time to recurrence and a poor overall prognosis".

Approximately 21,290 women were diagnosed with ovarian cancer in 2015 and an estimated 14,180 will die from the disease according to the American Cancer Society. Because ovarian cancer tends to be detected at a later stage of the disease, the five-year survival rate for ovarian cancer is 45%. Current treatment options are surgery, radiation and chemotherapy. There is currently no FDA approved cancer vaccine available for ovarian cancer.
