Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
42 patients were enrolled and entered the Titration Phase. 36 patients determined an effective dosage of sufentanil and were randomized to the Double-Blind Phase of the study. 2 patients then terminated from the study and did not take any doses after the Titration Phase. 34 patients participated in the Double-Blind Phase of the study.

Reporting Groups
  Description
Sequence 1

Open Label Titration Phase - Each patient determined the effective dosage of sufentanil for their pain (20, 30, 40, 60 or 80 mcg). Patients were then randomized to one of six sequences in the Double Blind Phase in which they took ten doses of study drug.

Double-Blind Phase/Sequence 1 - Patients took a dose of study drug, as needed for breakthrough pain, as follows: placebo treatments for the 2nd, 4th, and 7th episode of breakthrough pain and ARX-F02 (sufentanil) treatments for all other episodes of breakthrough pain (dosage of sufentanil determined in the Titration Phase).

Sequence 2

Open Label Titration Phase - Each patient determined the effective dosage of sufentanil for their pain (20, 30, 40, 60 or 80 mcg). Patients were then randomized to one of six sequences in the Double Blind Phase in which they took ten doses of study drug.

Double-Blind Phase/Sequence 2 - Patients took a dose of study drug, as needed for breakthrough pain, as follows: placebo treatments for the 2nd, 4th, and 8th episode of breakthrough pain and ARX-F02 (sufentanil) treatments for all other episodes of breakthrough pain (dosage of sufentanil determined in the Titration Phase).

Sequence 3

Open Label Titration Phase - Each patient determined the effective dosage of sufentanil for their pain (20, 30, 40, 60 or 80 mcg). Patients were then randomized to one of six sequences in the Double Blind Phase in which they took ten doses of study drug.

Double-Blind Phase/Sequence 3 - Patients took a dose of study drug, as needed for breakthrough pain, as follows: placebo treatments for the 2nd, 5th, and 9th episode of breakthrough pain and ARX-F02 (sufentanil) treatments for all other episodes of breakthrough pain (dosage of sufentanil determined in the Titration Phase).

Sequence 4

Open Label Titration Phase - Each patient determined the effective dosage of sufentanil for their pain (20, 30, 40, 60 or 80 mcg). Patients were then randomized to one of six sequences in the Double Blind Phase in which they took ten doses of study drug.

Double-Blind Phase/Sequence 4 - Patients took a dose of study drug, as needed for breakthrough pain, as follows: placebo treatments for the 3rd, 5th, and 7th episode of breakthrough pain and ARX-F02 (sufentanil) treatments for all other episodes of breakthrough pain (dosage of sufentanil determined in the Titration Phase).

Sequence 5

Open Label Titration Phase - Each patient determined the effective dosage of sufentanil for their pain (20, 30, 40, 60 or 80 mcg). Patients were then randomized to one of six sequences in the Double Blind Phase in which they took ten doses of study drug.

Double-Blind Phase/Sequence 5 - Patients took a dose of study drug, as needed for breakthrough pain, as follows: placebo treatments for the 3rd, 6th, and 8th episode of breakthrough pain and ARX-F02 (sufentanil) treatments for all other episodes of breakthrough pain (dosage of sufentanil determined in the Titration Phase).

Sequence 6

Open Label Titration Phase - Each patient determined the effective dosage of sufentanil for their pain (20, 30, 40, 60 or 80 mcg). Patients were then randomized to one of six sequences in the Double Blind Phase in which they took ten doses of study drug.

Double-Blind Phase/Sequence 6 - Patients took a dose of study drug, as needed for breakthrough pain, as follows: placebo treatments for the 3rd, 6th, and 10th episode of breakthrough pain and ARX-F02 (sufentanil) treatments for all other episodes of breakthrough pain (dosage of sufentanil determined in the Titration Phase).

  Description
Sufentanil Followed by Sufentanil and PBO

During the Titration Phase, patients titrated to the effective dosage of sufentanil NanoTab™(20, 30, 40, 60 or 80 mcg). One sufentanil NanoTab™ was taken as needed for breakthrough pain.

During the Double-Blind Phase, patients were then randomized to one of six treatment sequences, each of which included seven active (dosage determined in Titration Phase) and three placebo doses taken in random order per. One NanoTab™ was taken as needed for breakthrough pain.
