Participant Flow

Recruitment Details
Pre-assignment Details	A protocol amendment (Update #02) removed the option for patients to be randomized to Placebo; the study went from being a randomized study to a single arm study. The discrepancy in the number of patients who 'Started' the study and the Protocol Enrollment number is due to there being 2 patients randomized to Placebo prior to Update #02.

Arm/Group Title	Efatutazone Dihydrochloride
Arm/Group Description	Patients receive efatutazone dihydrochloride PO BID continuously. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Period Title: Overall Study
Started	13
Completed	11

Outcome Measures

1. Primary Outcome

Title	Confirmed Overall Response Rate Per the RECIST 1.1 Criteria
Description	The response rate (percentage) is the percent of patients whose best response was Complete Response (CR) or Partial Response (PR) as defined by RECIST 1.1 criteria. Percentage of successes will be estimated by 100 times the number of successes divided by the total number of evaluable patients.
Time Frame	Up to 24 weeks (8 cycles)

Arm/Group Title	Efatutazone Dihydrochloride
Arm/Group Description:	Patients receive efatutazone dihydrochloride PO BID continuously. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Overall Number of Participants Analyzed	11
Measure Type: Number; Number (95% Confidence Interval); Unit of Measure: percentage of patients
	0; (0 to 28)

2. Secondary Outcome

Title	Progression Free Survival (PFS) Determined Based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
Description	Progression free survival (PFS) is defined as the time from study entry to the date of disease progression or death resulting from any cause, whichever comes first. Progression is defined according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. The median and 95% confidence intervals are estimated using the Kaplan-Meier estimator.
Time Frame	Time from study entry to the first of either disease progression or death from any cause, assessed up to 5 years

Measure Type: Count of Participants; Unit of Measure: Participants
at least one grade 3 or worse AE	6 54.5%
at least one grade 4 or worse AE	3 27.3%

Adverse Events

Time Frame	Adverse events are assessed weekly during cycle 1, and then on day 1 (+/- 4 days) for cycles 2-4; then day 1 (+/- 7 days) of every odd numbered cycle for Cycle 5 and beyond; up to 5 years.
Adverse Event Reporting Description	Each CTCAE term is a representation of a specific event used for medical documentation & analysis & is a single MedDRA Lowest Level Term (LLT). All graded AEs are reported for completed patients. Serious AE (SAE) reports may include any secondary serious or non-serious events considered related to the primary event (the reason for filing an expedited report); collectively, these events are referred to as Expedited AEs, & appear in the SAE table.
Arm/Group Title	Efatutazone Dihydrochloride
Arm/Group Description	Patients receive efatutazone dihydrochloride PO BID continuously. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
