Outcome measures
Primary outcome
Part A: healthy volunteers (n= up to 15)
Primary/safety objective:
- To assess the safety, tolerability and pharmacokinetics of a single IV dose of OTL78
Part B/part C: patients (n= up to 24)
Primary/safety objective:
- To assess the safety, tolerability and pharmacokinetics of a single IV dose of OTL78
Secondary outcome
Part A: healthy volunteers (n= up to 15)
Secondary objective:
- To assess the pharmacodynamics of OTL78 by measuring the temporal relationship of fluorescence of superficial
tissues (skin/veins and mucosa).
Part B/Part C: patients (n=24)
Secondary objectives:
- To estimate the Sensitivity (or True Positive rate, TP/(TP+FN)) of OTL78 for detection of tissues expressing PSMA or prostate cancer during near infrared imaging (NIR)
- To estimate the Specificity (or True Negative rate, TN/(TN+FP)) of OTL78 for detection of PSMA+ tissue and prostate cancer cells during near infrared imaging (NIR)
- To estimate the False Positive rate (FP/(FP+TN)) of OTL78 for detection of tissues expressing PSMA or prostate cancer during near infrared imaging (NIR)
- To estimate the False Negative rate (FN/(FN+TP)) of OTL78 for detection of PSMA+tissues prostate cancer cells during near infrared imaging (NIR)
- To evaluate the tumor to background ratio (TBR)
Exploratory Objective:
- To evaluate the surgeons' rating for the utility of OTL78 IV injection and imaging system in visualizing prostate cancer and/or lymph nodes during surgery
Background summary
Surgery is the mainstay in the initial treatment of many solid tumors. Complete resection has shown to be an important prognostic indicator for survival. However, this can be challenging when the surgical field is observed with the naked eye only. Therefore, agents that improve tumor identification and the likelihood of complete resection are being developed. These agents are directed towards tumor-specific targets and emit light at non-visible wavelengths. By using near-infrared (NIR) camera systems, they may enable detection of malignant tissues and distinguish them from normal tissue. OTL78 is an imaging agent that specifically binds to the PSMA (prostate specific membrane antigen) which is expressed on prostate cells, particularly cancer and possibly involved lymph nodes. Intra-operative identification of cancer tissue using real-time imaging modalities that could improve tumor identification and demarcation would provide a very useful tool to reduce the frequency of positive resection margins and increase complete removal of locally spread tumor and involved lymph nodes. Complete removal of cancer and metastases may in turn reduce rates of re- interventions and therefore morbidity to help improve patient outcomes. As there is no clinical experience with OTL78, the study drug will first be studied in healthy volunteers and subsequently in patients to assess the safety, tolerability and pharmacokinetics The performance of OTL78 in intraoperative imaging of prostate cancer will be assessed in (Part B/part C, proof of concept).
Study objective
OTL78 is safe for use in healthy male individuals and patients with prostate cancer. OTL78 binds to malignant prostate tissue and malignant lymph nodes.
