Description of intervention(s) / exposure
EARLI-001 is a recombinant DNA nanoplasmid that uses the human survivin promoter to drive cancer-activated expression of secreted embryonic alkaline phosphatase (SEAP) to act as a biomarker for the detection of cancer. EARLI-001 is given as a single intravenous dose.
This is a phase 1 open-label study to assess the safety, tolerability, pharmacodynamics and pharmacokinetics of two single ascending doses of EARLI-001 in healthy participants at a single site in Australia. Up to 10 participants will receive the study drug at one of two dose levels (0.003mg/kg or 0.013mg/kg) via an intravenous infusion at a rate of ~1ml/minute. The following is how the participants will be dosed:
Cohort 1 (first 5 participants): 0.003mg/kg
Cohort 2 (last 5 participants): 0.013mg/kg
Participants will stay confined in the clinical unit to complete safety assessments for 24 hours post-dosing and will then return to the clinical site on Days 3,5,7, 14 and 28 days post-dose for follow-up assessments. The study drug will be administered to participants by trained nurses in adherence to the strict study protocol.

Outcomes
Primary outcome [1] 333326 0
To evaluate the safety and tolerability of EARLI-001 in healthy volunteers.
Safety assessments include the monitoring of the incidence and severity of adverse events. The participant will report these to site staff. Open-ended and non-leading verbal questioning of the participant will be used to enquire about AE occurrences.. The same doses of EARLI-001 used in this study (0.003mg/kg and 0.013mg/kg) have been trialled in cancer patients. Some of the cancer patients who were dosed with EARLI-001 experienced a mild to moderate post-infusion reaction (fever and or chills) after dosing. These symptoms resolved after the patients were treated with ibuprofen.
Clinically significant changes from baseline will also be monitored in:
- laboratory evaluations (haematology, chemistry, coagulation and urinalysis)
- electrocardiograms (ECG): using a 12 lead ECG machine
- vital signs including; oral temperature, pulse rate, respiratory rate and blood pressure. Temperature, blood pressure and pulse rate are assessed using a vitals machine. Respiratory rate is assessed using a 30-second manual count.
- physical examinations include examinations of the following; general appearance, head, ears, eyes, nose, throat, neck, skin, cardiovascular system, respiratory system, gastrointestinal system, musculoskeletal system, lymph nodes and nervous system. This will be performed by a study-delegated registered physician.

Safety
Statistical methods / analysis
This is an open-label, early development study, and therefore no statistical considerations were involved in the sample size determination. It is expected that the sample size of 10 subjects in 2 cohorts should be adequate for the evaluation of safety, tolerability and pharmacokinetics in this single-dose study.

Statistical Analysis Plan:
Adverse events: will be summarized by the Medical Dictionary for Regulatory Activities (MedDRA) system organ class and preferred term. All subjects in the safety analysis set will be included in the summaries. Events will be summarized on the basis of the date of onset for the event. No statistical testing will be performed. All AEs collected during the study will be presented in a listing.
Clinical Laboratory data Summaries of clinical laboratory results and change from baseline will be performed using descriptive statistics by scheduled visit. All subjects in the safety population will be included in these summaries. No statistical testing will be performed.
Other safety evaluations: Individual data for physical examination findings, prior and concomitant medications and medical history will be provided. Twelve-lead ECGs and vital signs measurements will be listed by subject and summarized by the incidence of events/abnormalities or descriptive statistics as appropriate. No statistical testing will be performed.

Summary
Brief summary
The purpose of this study is to determine the assess the safety, tolerability, pharmacodynamics and pharmacokinetics of EARLI-001, a product developed to asses with the detection of cancer.

Who is it for?
You may be eligible for this study if you are a healthy adult under the age of 55.

Study details

Participants will receive the study drug via an infusion in the vein and be required to stay at the testing clinic for 24 hours for observation. They will then be required to attend follow-up assessments on days 3,5,7, 14 and 28.

As part of this study, we will be collecting blood samples for both safety and research purposes. During the study, the estimated total blood volume to be collected will be approximately 140 mL (approximately 0.6 cups or 7 tablespoons). As a reference, a standard blood donation is 470 mL in any 12-week period. At follow-up visits, participants will also undergo physical examinations, vital sign assessments (blood pressure, pulse rate, breathing rate and temperature) and electrocardiograms for the assessment of safety.

It is hoped that this research will help determine if this product is safe for use, to then be used further in future studies to determine whether this product can be used to assist cancer detection.
