Study Evaluating the Efficacy and Safety of Subcutaneous Methylnaltrexone (MOA-728) for the Treatment of Opioid-Induced-Constipation
A Multicenter, Randomized, Double-Blind, Placebo-Controlled, And Parallel-Group Study Of Subcutaneous Methylnaltrexone (MOA-728) For The Treatment Of Opioid-Induced Constipation In Adult Subjects
Tutkimuksen yleiskatsaus
Yksityiskohtainen kuvaus
Subjects received subcutaneous methylnaltrexone (also referred to as MOA-728 or MNTX) or placebo every other day beginning on Day 1 up to a maximum of 7 doses during the 2-week double-blind period.
Inclusion criteria for this study included subjects with advanced illness or subjects with chronic nonmalignant pain. The actual study population included only subjects with cancer-related advanced illness.
All subjects who completed the double-blind treatment phase of this study could elect to receive methylnaltrexone during a 12-week open-label extension study, provided eligibility criteria were met. Subjects who did not continue in the open-label extension study had a follow-up visit 2 weeks after their last dose of test article.

Aikaikkuna |
|---|---|---|

The Proportion of Subjects Having a Rescue-free Bowel Movement (RFBM) Within 4 Hours After the First Injection.
Aikaikkuna: Up to 4 hours after the first injection
|
There were 2 co-primary endpoints for this study.
This measurement is the first of the 2 co-primary endpoints.
This endpoint measures the percentage of patients who had an RFBM within 4 hours after the first dose of test article during the double-blind period; data are expressed as percentages of patients for the MNTX and placebo groups.
To qualify as rescue free, the bowel movement could not occur within 6 hours after a rectal intervention (ie, rectal suppository, enema, manual disimpaction).
Note that efficacy results (primary and secondary outcomes) are presented for the double-blind period only.
Therefore, no efficacy results are presented for the open-label period.

The Proportion of Subjects Having a Rescue-free Bowel Movement (RFBM) Within 4 Hours After Each Dose During Double-blind Period.
Aikaikkuna: Within 4 Hours After Each Dose During the 2 weeks Double-Blind Period
|
This measurement is the second of the 2 co-primary endpoints.
This endpoint measures the percentage of patients who had an RFBM within 4 hours after each dose of test article during the double-blind period; data are expressed as percentages of patients by dose (first, second, third, fourth, etc.) for the MNTX and placebo groups.
The definition of RFBM is described above (see first co-primary endpoint).

Percentage of Injections Resulting in RFBM Within 4 Hours After Test Article Administration.
Aikaikkuna: Within 4 Hours After Each Dose During the 2 weeks Double-Blind Period
|
This endpoint measures the percentage of injections resulting in RFBMs within 4 hours after test article administration during the double-blind period.
The percentage of injections resulting in RFBMs is calculated for each patient and then data are expressed as the mean (± standard deviation) percentage for the MNTX and placebo groups.
The definition of RFBM is described above (see first co-primary endpoint).
