Study summary

This first-in-human study is designed to establish the safety and tolerability of ATR-101 in patients with advanced adrenocortical carcinoma whose tumor has progressed on standard therapy. Information will also be collected to determine how long ATR-101 stays in the blood, and if any effect on tumor progression is seen. Biomarkers (blood and urine tests) will determine if any effects on production of steroid hormones (cortisol, aldosterone, estrogen and testosterone) are seen.

What researchers measure

Primary outcomes

  1. Frequency of dose-limiting toxicity and determination of maximum tolerated dose

    Adverse events will be recorded and tabulated by grade and system organ class according to CTCAE v 4.03. Laboratory measures and ECGs will be assessed.

    Time frame: Occurrence of DLT at 28 days

Secondary outcomes

  1. Area under the plasma concentration versus time curve (AUC) of ATR-101

    Plasma levels of ATR-101 will be assessed after daily oral dosing and pharmacokinetic parameters will be calculated.

    Time frame: Day 1 and Day 22

  2. Change in plasma cortisol levels

    Time frame: Baseline and day 22

  3. Change in objective measurement of tumor size

    CT or MRI scans will be read according to RECIST 1.1

    Time frame: Baseline and 8 weeks
