- Data from the dose escalation phase of the EC1169 trial reported at ESMO in October showed that total target tumor burden reduction was observed in 4 of the 6 patients with measurable soft tissue disease treated at doses of 3.8 mg/m 2 and higher.
- One of these patients demonstrated the first confirmed radiologic partial tumor response (PR) as measured by RECIST 1.1 criteria.
- Two patients demonstrated confirmed prostate specific antigen reductions of greater than 50%, one of whom went on to demonstrate the PR.
- EC1169 was well tolerated without causing dose-limiting hematologic toxicity frequently associated with traditional chemotherapy. Primary toxicities included fatigue and gastrointestinal (GI) toxicity; predominantly grade 1 and 2, reversible and responsive to simple medication.
- The company has confirmed 6.5 mg/m 2 once per week, administered 2 weeks out of a 3 week cycle, as the maximum clinical dose and is moving into the expansion phase where 2 cohorts of metastatic castration resistant prostate cancer (mCRPC) patients will be evaluated. One cohort will include patients who previously received a taxane-based therapy and the other cohort will include taxane-naïve patients. Initial patients in this expansion phase have consented to participate and are expected to be treated this month.
- A dose of 6.0 mg/ m 2 was established as the maximum twice per week dose, administered 2 weeks out of a 3 week cycle, which is being used in the expansion phase of the trial where the company will evaluate EC1456 in select folate receptor (FR)-positive NSCLC patients, identified by the companion imaging agent etarfolatide.
- Patients included in this phase of the trial will have received first-line chemotherapy and may have also been treated with anti-PD-1 therapy.
- EC1456 was well tolerated during dose escalation, with primary toxicities including fatigue, GI toxicity, and electrolyte disturbance; predominantly grade 1 and 2, reversible and responsive to simple medication.
- In spite of the inclusion of patients in the dose escalation phase who were not selected as positive for the targeted FR, most patients demonstrated stable disease as best response and several patients demonstrated a reduction in target tumor volume.
- Efficacy and safety data from expansion cohorts for both EC1456 and EC1169 are expected to be reported at medical conferences.
- Data from an EC1456 surgical debulking study. This study is designed to assess various metrics related to cell targeting and intratumoral delivery of drug payload.
- Data from an EC1169 receptor occupancy study. This study is designed to provide insight into the drug's interaction with the target receptor.
- New pre-clinical data on the CAR-T program are expected to be reported at a scientific conference.
Research and development expenses were $6.0 million for the third quarter of 2016, compared to $6.6 million for the same period in 2015. The decrease was primarily attributable to a decrease in compensation expense and a decrease in expenses related to the TARGET trial, which is now complete. The net effect of these decreases was partially offset by increases related to the EC1456 and EC1169 dose escalation trials and increases in manufacturing and other research expenses related to EC1456 and EC1169.General and administrative expenses were $3.0 million for the third quarter of 2016, compared to $3.8 million for the same period in 2015. The decrease was primarily attributable to a decrease in compensation expense and a decrease in expenses related to professional fees and employee benefits. Cash, cash equivalents and investments were $146.7 million at September 30, 2016, compared to $180.3 million at September 30, 2015, and $173.6 million at December 31, 2015. Financial Expectations The company updated its financial expectations and now anticipates its cash balance at the end of 2016 to be above $135 million. About EC1456 and the Phase 1 Trial EC1456 is an investigational therapeutic SMDC constructed of a high affinity FR-targeting ligand conjugated through a spacer and bioreleasable linker system to a potent cytotoxic microtubule inhibitor, TubBH. Patient FR-status will be determined using the investigational companion imaging agent, etarfolatide. EC1456 and etarfolatide are currently being evaluated in a phase 1 study in patients with advanced solid tumors (ClinicalTrials.gov Identifier: NCT01999738). The open-label, multicenter, non-randomized, study is divided into two parts. The first part of the study was designed to determine the maximum clinical dose and recommended Phase 2 dose of EC1456 in patients with metastatic or locally advanced solid tumors. Endocyte has now initiated the expansion phase of the study which is designed to evaluate the efficacy of EC1456 in patients with NSCLC known to express the FR and treated with the maximum clinical dose of EC1456. The twice weekly (BIW) dosing schedule at a 6.0 mg/m 2 dose will be evaluated and then upon completion of this dosing schedule, additional patients will be enrolled in a once per week dosing schedule cohort. Single agent anti-tumor response will be evaluated, which will inform and may trigger additional work in combination therapies and indications such as triple-negative breast cancer, ovarian cancer and endometrial cancer. About EC1169 and the Phase 1 Trial EC1169 is an investigational therapeutic SMDC constructed of a high affinity prostate specific membrane antigen (PSMA)-targeting ligand conjugated through a bioreleasable linker system to a potent microtubule inhibitor, tubulysin B hydrazide (TubBH). Patient PSMA-status will be determined using the investigational companion imaging agent, EC0652. EC1169 and EC0652 are currently being evaluated in a phase 1 study in patients with mCRPC (ClinicalTrials.gov Identifier: NCT02202447). The open-label, multicenter, non-randomized, study is divided into two parts. The first part of the study, now complete, was designed to determine the maximum clinical dose and recommended Phase 2 dose of EC1169 in patients with prostate cancer.
Endocyte has now initiated the second part of the study which is designed to evaluate the efficacy of EC1169 in taxane-exposed and taxane-naïve mCRPC, with a primary study endpoint of radiographic progression free survival in patients selected as PSMA-positive.Conference Call Endocyte management will host a conference call today at 4:30 p.m. EST.

About Endocyte Endocyte is a biopharmaceutical company and leader in developing targeted therapies for the treatment of cancer and other serious diseases. Endocyte uses its proprietary drug conjugation technology to create novel SMDCs and companion imaging agents for personalized targeted therapies. The company's SMDCs actively target receptors that are over-expressed on diseased cells relative to healthy cells. This targeted approach is designed to enable the treatment of patients with highly active drugs at greater doses, delivered more frequently and over longer periods of time than would be possible with the untargeted drug alone. The companion imaging agents are designed to identify patients whose disease over-expresses the target of the therapy and who are therefore more likely to benefit from treatment. For additional information, please visit Endocyte's website at www.endocyte.com.
