Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Placebo (0mg/day)

Intraspinal Placebo delivered continuously for 29 days via an implantable infusion system

Group Type PLACEBO_COMPARATOR

Intraspinal Gabapentin

Intervention Type DRUG

Surgical implantation of a drug infusion system with intrathecal (spinal) delivery of active drug (1 of 3 possible dose levels) or placebo (saline) for 22 days followed by 7 days of infusion at half dose level. Subjects may then continue in open-label treatment with study drug. Dosage in open-label may be adjusted to meet subject needs.

Gabapentin Low (1mg/day)

Intraspinal Gabapentin Low delivered continuously for 22 days via an implantable infusion system followed by 7 days infusion at half dose

Group Type ACTIVE_COMPARATOR

Intraspinal Gabapentin

Intervention Type DRUG

Surgical implantation of a drug infusion system with intrathecal (spinal) delivery of active drug (1 of 3 possible dose levels) or placebo (saline) for 22 days followed by 7 days of infusion at half dose level. Subjects may then continue in open-label treatment with study drug. Dosage in open-label may be adjusted to meet subject needs.

Gabapentin Medium (6mg/day)

Intraspinal Gabapentin Medium delivered continuously for 22 days via an implantable infusion system followed by 7 days infusion at half dose

Group Type ACTIVE_COMPARATOR

Intraspinal Gabapentin

Intervention Type DRUG

Surgical implantation of a drug infusion system with intrathecal (spinal) delivery of active drug (1 of 3 possible dose levels) or placebo (saline) for 22 days followed by 7 days of infusion at half dose level. Subjects may then continue in open-label treatment with study drug. Dosage in open-label may be adjusted to meet subject needs.

Gabapentin High (30mg/day)

Intraspinal Gabapentin High delivered continuously for 22 days via an implantable infusion system followed by 7 days infusion at half dose

Group Type ACTIVE_COMPARATOR

Intraspinal Gabapentin

Intervention Type DRUG

Surgical implantation of a drug infusion system with intrathecal (spinal) delivery of active drug (1 of 3 possible dose levels) or placebo (saline) for 22 days followed by 7 days of infusion at half dose level. Subjects may then continue in open-label treatment with study drug. Dosage in open-label may be adjusted to meet subject needs.
