Study Endpoints

Primary Endpoints

Progression Free Survival (PFS) centrally assessed by Blinded Independent Review Committee (BIRC)
After observing approximately 88 PFS events as per BIRC assessments, expected after approximately 33 months from study start

PFS is defined as the time from randomization to the first occurrence of progression (centrally assessed by Blinded Independent Review Committee (BIRC) according to RECIST v1.1) or death due to any cause.

Progression Free Survival (PFS) as Per Adjudicated Central Radiology Review
Time from randomisation to dates of disease progression, death from any cause or last tumor assessment, reported between day of first patient randomised, 10 January 2007, until cut-off date 02 April 2010

Progression free survival (PFS) is defined as the time from randomization to the date of first documented disease progression or death from any cause. The primary analysis of PFS was based on the independent central adjudicated assessment using Kaplan-Meier method.

Change in Growth Hormone (GH) Level From Screening to End of Study (Week 24)
Screening to end of study (Week 24)

Growth hormone (GH) level was the average value measured in 3 blood samples collected at 15 minute intervals at each visit. GH was measured with an automated immunometric assay in a central laboratory.

Change in Insulin-like Growth Factor 1 (IGF-1) Level From Screening to End of Study (Week 24)
Screening to end of study (Week 24)

Insulin-like growth factor 1 (IGF-1) level was measured in a blood sample with an automated immunometric assay in a central laboratory.

Overall Survival
Number of Participants With Treatment Success From Day 10 to Day 13
Day 10 to Day 13

Treatment Success was defined as: less than 2 episodes of vomiting on average per day for the 4 days prior to Day 14 \[from Day 10 to Day 13\] and no use of an Nasogastric Tube (NGT) since at least Day 10 and no use of an anticholinergic agent until Day 14. Treatment Failure is defined as: 2 or more episodes of vomiting per day on average for the 4 days prior to Day 14 or use of an NGT after Day 9 or use of an anticholinergic agent before Day 14 or withdrawal from the trial between Day 1 and Day 14 (included), whatever the cause.

Shrinkage of tumor size and diameter of 3 respectively 6 months

Octreotide+ EverolimusEXPERIMENTALEverolimus was administered in accordance with a 10-mg daily dosing regimen (two 5-mg tablets) in conjunction with octreotide 30 mg intramuscularly (i.m.) every 28 days. Patients were treated until progression or unacceptable toxicity. Each treatment cycle lasted 28 days. Patients received their first dose of everolimus at Cycle 1, Day 1. Administration of octreotide was performed every 28 days (± 4 days) starting on Cycle 1, Day 1.
Octreotide+ PlaceboPLACEBO_COMPARATORMatching placebo was administered in accordance with a 10-mg daily dosing regimen (two 5-mg tablets) in conjunction with octreotide 30 mg intramuscularly (i.m.) every 28 days. Patients were treated until progression or unacceptable toxicity; Each treatment cycle lasted 28 days. Patients received their first dose of matching placebo at Cycle 1, Day 1. Administration of octreotide was performed every 28 days (± 4 days) starting on Cycle 1 Day 1.
Octreotide 30 mg every 21 daysEXPERIMENTALPatients received octreotide 30 mg every 21 days intramuscularly (im) for 6 months, a total of 8 doses. At each study visit, octreotide was administered only after completion of all scheduled efficacy and safety evaluations for that visit. Octreotide was injected im into the right or left gluteal regions. The injections were initially administered by a trained and authorized member of the investigational team. When no study visit at the investigational site was required, the injections were given by a trained nurse or the family doctor.
Octreotide 60 mg every 28 daysEXPERIMENTALPatients received octreotide 60 mg every 28 days intramuscularly (im) for 6 months, a total of 6 doses. Octreotide mg was administered as two 30 mg injections. At each study visit, octreotide was administered only after completion of all scheduled efficacy and safety evaluations for that visit. Octreotide was injected im into the right or left gluteal regions. The injections were initially administered by a trained and authorized member of the investigational team. When no study visit at the investigational site was required, the injections were given by a trained nurse or the family doctor.

Frequently asked questions about SMS995

What is SMS995 used for?

SMS995 is an investigational small molecule being developed for Irritable Bowel Syndrome (IBS), a gastrointestinal condition. It is currently in Phase 1 clinical development and is not yet approved by regulatory authorities.

Who makes SMS995?

SMS995 is being developed by Novartis AG, a multinational pharmaceutical company traded on the New York Stock Exchange under the ticker NVS. The drug is currently in Phase 1 clinical trials for Irritable Bowel Syndrome.

What phase is SMS995 in?

SMS995 is in Phase 1 clinical development. It is an investigational drug for Irritable Bowel Syndrome and has not been approved by the FDA or other regulatory agencies. One Phase 1 trial has been completed.

What clinical trials is SMS995 in?

SMS995 has one completed Phase 1 clinical trial, registered under NCT00584298. The trial, titled 'Feasibility and Reproducibility of Barostat Assessments of Colorectal Sensation During Colorectal Distention and Its Pharmacological Modulation Using Octreotide,' enrolled 50 female participants with Irritable Bowel Syndrome across the United States, Canada, Sweden, and the United Kingdom.

Is SMS995 the same as octreotide?

No, SMS995 is not the same as octreotide. The completed Phase 1 trial NCT00584298 used octreotide as a pharmacological modulator to assess colorectal sensation, but SMS995 is the investigational drug being developed for Irritable Bowel Syndrome. The trial was designed to evaluate the feasibility of barostat assessments.
