Description of intervention(s) / exposure
Approximately 6-8 subjects with advanced solid tumors will be enrolled to receive one cycle of PIN-2 treatment (administered intravenously) consisting of 300 µg PIN-2, 3x per week (Day1, Day3 and Day5 of the week) for 2 weeks followed by a one week rest period. Patient who do not experience >grade 2 toxicity and in the opinion of the Investigator may benefit from a second course can receive a second course of 2 weeks treatment following a one week rest period on the same schedule as above, apart from tumor biopsies which may be performed at the discretion of the investigator. The second cycle will be given at the same dose. No dose escalation or dose reduction is permitted. No more than 2 courses will be given. PD samples will be obtained on the last day of dosing. NCI CTCAE v4.0 toxicity grading scale will be used. No intervention adherence will be assessed.

Statistical methods / analysis
No preplanned statistical analysis is proposed because (a) the exploratory nature of the
study; (b) the small number of subjects; and (c) since each subject will be it’s own control
– post-treatment vs. pre-treatment to be evaluated.

Each subject will serve as his/her own control (single subject approach “SSA”).

Justification for the Choice Statistical Approach to Assess the Immune Response.
PIN-2 is a new and novel unique compound having demonstrated unique
immunomodulatory activity as determined from changes in the presence of immune
markers in the blood and immune cells in the tumor environment.
The intent of this study is to demonstrate a similar response (signals) in the human as
was observed in the mouse as well as in vitro studies with macrophages.
The SSA is a powerful research approach since it provides feedback quickly about the
effects of the treatment. The effects of treatment must be demonstrated in individual
subjects. This determines whether the treatment is working or not and permits the
observation of day to day changes. The SSA permits the investigator to draw
conclusions regarding the factors that control the dependent variable. To be an
acceptable evaluation of the treatment, the results for each subject must demonstrate
intra and inter subject replication.

Immunogenicity, Pharmacokinetics, Safety:
Analyses will be quantitative and will be focused on changes comparing post (following
administration of PIN-2) versus pre (baseline) of the immune response (changes in
immune cell population in the blood, changes in blood biomarkers and changes in
biomarkers (IHC) in the lymph node or tumor microenvironment or both) pre and post
administration of PIN-2 will be determined by the delta looking for the signal and trend.

Brief summary
The purpose of this study is to investigate whether a new drug called PIN-2 is safe and activates the immune system in patients with advanced solid tumours.

Who is it for?
You may be eligible to join this study if you are aged 18 years or above and have a histologic diagnosis of an advanced solid tumor.

Study details
All participants in this study will receive one cycle of chemotherapy treatment with the drug, PIN-2 (Precision Immune Stimulants). PIN-2 will be administered intravenously (i.e. directly into the vein) 3 x per week for 2 weeks followed by a one week rest period. If tolerated and deemed beneficial, a second identical course may be administered. No more than 2 courses in total will be given.

Participants will be regularly monitored for safety, and asked to provide a number of blood samples across a 5 week period to assess how the body processes and responds to the drug. Tissue samples (tumor and/or lymph node) will also be obtained, if possible, at pre-treatment and again at the conclusion of each treatment cycle for evaluation. Patients who are eligible for and agree to participate in the biopsy will have tumor biopsy prior to treatment and at week 3.

This study will help find new methods of treatment for the patients with solid tumors.
