Primary Outcome Measures:
  • Change From Baseline in Mean Pain Score on the Numeric Rating Scale (NRS). [ Time Frame: Baseline and 9 months ]
    The primary efficacy variable was the pain severity score measured on an 11 point NRS on which 0=no pain and 10=worst possible pain. The primary efficacy evaluation was the change from baseline in mean pain score on the NRS.

Enrollment: 237
Study Start Date: July 2006
Study Completion Date: January 2009
Primary Completion Date: January 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
DVS SR Open Label
Daily dose of 100mg or 200mg at the investigators discretion. Subjects already randomized at a dose of 400mg may continue at that dose level.
Drug: Desvenlafaxine Succinate Sustained-Release (DVS SR)
Other Name: DVS SR


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Outpatients who have completed double-blind treatment in study 322 (NCT01050218) for DPN. Subjects must have completed all scheduled evaluations, with no major protocol violations and no events that, in the opinion of the investigator, would preclude the subject's entry into the long-term open-label study.
  • Women of childbearing potential must have a negative serum pregnancy test on day 91 of the short-term study. A woman of childbearing potential is one who is biologically capable of becoming pregnant. "Biologically capable" includes women who are using contraceptives or whose sexual partners are either sterile or using contraceptives. Sexually active women participating in the study who are biologically capable of becoming pregnant must use a medically acceptable form of contraception during the study and for at least 15 days after the last dose of test article. Medically acceptable forms of contraception include oral contraceptives, transdermal, injectable, or implantable methods, intrauterine devices, or properly used double-barrier contraception, eg, condom plus diaphragm.

Exclusion Criteria:

  • Presence of any new and/or clinically important medical condition that might compromise subject safety (including, but not limited to, significant changes in glycemic control).
  • Pregnancy, lactation, or plans to become pregnant during the study.
  • Use of prohibited treatments.
  • Meets any of the exclusion criteria listed for study 322 (NCT01050218).
