West Lafayette, Ind., Feb. 26, 2018 – Endocyte, Inc. (NASDAQ Global Market:ECYT), a biopharmaceutical company developing targeted therapeutics for personalized cancer treatment, today provided an update on its corporate strategy and announced financial results for the fourth quarter and full year ending Dec. 31, 2017.

“Following a successful End of Phase 2 meeting with the FDA, we are excited to launch the VISION trial, a phase 3 registration trial of 177Lu-PSMA-617 in patients with prostate cancer,” said Mike Sherman, president and CEO of Endocyte. “After extensive collaboration with prostate cancer specialists around the world, the robust and sophisticated VISION trial design will be attractive to patients and physicians when we begin enrollment in the second quarter of 2018.”

“In addition, we were pleased that Caryn Barnett and Theresa Bruce recently joined our team, both seasoned leaders with strong track records of executing late stage oncology development programs,” added Mr. Sherman. “We expect 2018 to be a critical year of execution for us, as we will not only initiate VISION, but also bring our adaptor-controlled chimeric antigen receptor t-cell (CAR T-cell) program into the clinic in the fourth quarter of 2018.”

177Lu-PSMA-617 Phase 3 VISION Trial Design Finalized

Following a successful End of Phase 2 meeting with the U.S. Food and Drug Administration (FDA), Endocyte finalized the phase 3 VISION trial design for 177Lu-PSMA-617. The trial will include two interim assessments of efficacy, which could potentially lead to an early approval for 177Lu-PSMA-617.

The VISION trial is an international, prospective, open-label, multicenter, randomized phase 3 study of 177Lu-PSMA-617 for the treatment of patients with progressive prostate specific membrane antigen (PSMA)-positive metastatic castration-resistant prostate cancer (mCRPC), who have received at least one novel androgen axis drug (NAAD) and at least one taxane regimen. VISION will enroll up to 750 patients with PSMA-positive scans, randomized in a 2:1 ratio to receive either 177Lu-PSMA-617 and best supportive care alone or in combination with a NAAD (physician’s choice), versus best supportive care alone or in combination with a NAAD (physician’s choice). Best supportive care alternatives are palliative in nature. Patients treated with 177Lu-PSMA-617 will receive 7.4 gigabecquerel (GBq) intravenously every six weeks for a maximum of six cycles. The trial will be stratified by the physician’s choice of using a NAAD or not, so the use of NAAD’s will be balanced between trial arms.

The primary endpoint of the study will be overall survival (OS). Secondary endpoints include radiographic progression free survival, response evaluation criteria in solid tumors (RECIST) response, and time to first symptomatic skeletal event. Interim efficacy analyses of OS will be conducted at 50% and 70% of the 489 targeted events.

Enrollment of the trial is expected to begin in the second quarter of 2018 and is expected to be completed in 18-24 months. The first interim assessment of OS could occur as early as the second half of 2019.

Announced Agreement for Clinical Supply of Lutetium with ITM

Endocyte also announced an agreement with ITM Isotopen Technologien München AG, which will provide clinical supply of no-carrier-added Lutetium for the manufacturing of 177Lu-PSMA-617.

Added Experienced Clinical Trial Professionals to Ensure Strong Execution

In addition, today Endocyte announced that it recently added key capabilities to support the success of its clinical programs.

Caryn Barnett joined Endocyte as Senior Director, Clinical Operations with global responsibility for Endocyte clinical trials. She has over 22 of years’ experience in the pharmaceutical industry, most recently as Director of Clinical Operations, North America Oncology at Eli Lilly and Company. Caryn’s accomplishments include her recent leadership in executing four simultaneous global oncology registration programs, each of which were subsequently approved by the FDA.

Theresa Bruce joined Endocyte as Head of European Clinical Operations following 25 years in the field of clinical research, with the last 20 dedicated to oncology. Theresa brings a significant understanding of the regulatory landscape, particularly in Europe. Additionally, she played a lead role in developing next generation prostate cancer therapeutics in these regions, with her involvement in the operational execution of several phase 3 prostate cancer studies including, most notably, the development of abiraterone (Zytiga®) from early-stage trials through registration.

CAR T-Cell Therapy Expected to Begin Clinical Development in the Fourth Quarter of 2018

Endocyte has also finalized plans for the clinical development of its adaptor-controlled CAR T-cell therapy in patients with osteosarcoma. Endocyte’s approach utilizes an autologous CAR T-cell targeting fluorescein isothiocyanate (FITC), an agent otherwise not present in the human body. With the administration of CAR T adaptor molecules (CAMs) which bind to tumor targets and to the CAR T-cells, the approach potentially enables controlled engagement of the CAR T-cells. This control over the antigen target differentiates the approach to earlier generation CAR T programs. In collaboration with Michael Jensen, MD of Seattle Children's Research Institute, pre-clinical evaluations have been completed and clinical evaluation is expected to begin in the fourth quarter of 2018.

In this trial, patients will be selected based on the presence of folate receptor positive disease. Following administration of the FITC-targeted CAR T-cells, the protocol provides for intra-patient dose escalation of CAMs. Patients will be monitored following each CAM dose to assess immune response, providing for rapid feedback on activity and safety of the therapy. This innovative design is intended to gradually build the immune response, thereby allowing for the potential to maximize antitumor activity with the intent to avoid severe cytokine release syndrome as well as CAR T-cell exhaustion.

Through Endocyte’s collaboration with Purdue University, multiple additional CAMs are in pre-clinical development, directed against distinct targets including, potentially, carbonic anhydrase 9, cholecystokinin-2 receptor (CCK2R), neurokinin-1 receptor (NK1R), among others.

Fourth Quarter 2017 Financial Results

Endocyte reported a net loss of $8.6 million, or $0.18 per basic and diluted share, for the fourth quarter of 2017, compared to a net loss of $11.1 million, or $0.26 per basic and diluted share for the same period in 2016.

Research and development expenses were $5.1 million for the fourth quarter of 2017, compared to $8.2 million for the same period in 2016. The decrease was primarily attributable to: a decrease of $1.4 million in compensation expense as a result of employee terminations since December 31, 2016, including those resulting from the company’s restructuring in June 2017; a decrease of $1.0 million in manufacturing expense for EC1169; a decrease of $0.7 million in expenses related to trial and manufacturing costs for EC1456; and a decrease of $0.6 million in expenses related to pre-clinical work and general research, including the development of EC2629. These decreases were partially offset by: an increase of $0.6 million in expenses related to consulting fees for PSMA-617 and in expenses related to our CAR T-cell therapy program.

General and administrative expenses were $3.7 million for the fourth quarter of 2017, compared to $3.1 million for the same period in 2016. The increase was primarily attributable to an increase in expenses related to legal and professional fees and an increase in compensation expense, including stock compensation expense.

Cash, cash equivalents and investments were $97.5 million at Dec. 31, 2017, compared to $103.1 million at Sept. 30, 2017, and $138.2 million at Dec. 31, 2016.

Financial Expectations

The company anticipates its cash, cash equivalents and investments balance at the end of 2018 to exceed $50 million. Endocyte has sufficient cash to fund its activities into the second half of 2019 through many important milestones.
