This study is designed to provide continued access to BEMA Fentanyl for those subjects who previously participated in FEN-202 and who wish to continue using BEMA Fentanyl for the treatment of their breakthrough cancer pain.

This was an open label, long-term, extension study designed to provide continued access to EMA Fentanyl to those patients with breakthrough cancer pain who were treated for at least 2 weeks in FEN-202, the long term safety study used for worldwide registration. Patients were followed in an outpatient setting. Use of BEMA Fentanyl and occurrence of serious adverse events (SAEs) were monitored. Throughout the study, all patients continued their background opioid regimen and were permitted to use their rescue medication if adequate pain relief was not realized within 30 minutes following application of BEMA Fentanyl.

Inclusion Criteria:

1. previously qualified for and participated in study FEN-202 for at least 2 weeks,
2. wish to continue using BEMA Fentanyl for treatment of breakthrough pain episodes, and
3. provide signed informed consent at screening prior to any study procedures.

Exclusion Criteria:

1. they have developed a new medical condition after initial enrollment in FEN-202 which, in the opinion of the investigator, would preclude safe and appropriate use of BEMA Fentanyl or participation in this study, or
2. there is evidence of improper use of the study drug.

Adverse events were not recorded in this study because non-serious AEs have already been assessed in FEN-201 and FEN-202.
