Updated data will be presented on EC1456-01, a two part phase 1 dose escalation (Part A) and expansion (Part B) study. The presentation includes data for 87 Part A treated patients with advanced solid tumors and 6 Part B treated patients with FR-positive non-small cell lung cancer (NSCLC) as of the data cutoff on
An update also will be provided for EC1169-01, a two-part phase 1 dose escalation (Part A) and expansion (Part B) study in patients with metastatic castration-resistant prostate cancer (mCRPC). The presentation includes data for the expansion phase (Part B) for 24
taxane-exposed mCRPC patients and 16 taxane-naïve mCRPC patients as of the data cutoff on
The posters will be available on Endocyte's website following presentation at the conference.
Presentations are as follows:
|Title:||Phase 1 dose escalation study of the folate receptor-targeted small molecule drug conjugate EC1456|
|Session Title:||Poster Session: Developmental Therapeutics—Clinical Pharmacology and Experimental Therapeutics|
|Title:||Phase 1 study of the PSMA-targeted small-molecule drug conjugate EC1169 in patients with metastatic castrate-resistant prostate cancer (mCRPC)|

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, tubulysin B hydrazide (TubBH). Patient FR-status is determined using the investigational companion imaging agent, etarfolatide. EC1456 is currently being evaluated in a phase 1 study in patients with advanced solid tumors (Part A) and FR-positive NSCLC (Part B) (ClinicalTrials.gov Identifier: NCT01999738) and a phase 1 exploratory study in patients with ovarian cancer undergoing surgery (ClinicalTrials.gov Identifier: NCT03011320).
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, TubBH. Patient PSMA-status is determined using the investigational companion imaging agent, EC0652. EC1169 is currently being evaluated in a phase 1 study in patients with metastatic castration-resistant prostate cancer (mCRPC) (ClinicalTrials.gov Identifier: NCT02202447).
Endocyte Forward-Looking Statement
Certain of the statements made in this press release are forward looking, such as those relating to the company's development programs and upcoming milestones. Actual results or developments may differ materially from those projected or implied in these forward-looking statements. Factors that may cause such a difference include risks that the company may experience delays in the completion of its clinical trials (whether caused by competition, adverse events, patient enrollment rates, shortage of clinical trial materials, regulatory issues or other factors); risks that data from its clinical trials may not be indicative of
subsequent clinical trial results; risks related to the safety and efficacy of the company's product candidates; risks that early stage preclinical data may not be indicative of subsequent data when expanded to additional pre-clinical models or to subsequent clinical data; risks that evolving competitive activity and intellectual property landscape may impair the company's ability to capture value for the technology; estimates of the potential markets for its product candidates; estimates of the capacity of manufacturing and other facilities required to support its product candidates; projected cash needs; and expected future revenues, operations, expenditures and cash position.
