Study summary

What the protocol is testing.

The purpose of this study was to determine whether monthly deep subcutaneous (s.c.) injections of lanreotide Autogel (Somatuline Depot) were effective and safe in controlling diarrhoea and flushing by reducing the usage of s.c. short-acting octreotide as a rescue medication to control symptoms in subjects with carcinoid syndrome.

Full detailed description

This study consisted of a Screening period, conducted up to 4 months before randomisation, followed by three phases: a 16-week, double blind (DB), randomised, placebo-controlled phase; a 32-week initial open label (IOL) phase; and a long term open label extension (LTOLE) phase. The DB phase evaluated lanreotide Autogel versus placebo in subjects with a history of carcinoid syndrome (flushing and/or diarrhoea). This was followed by a 32-week IOL phase in which all subjects received lanreotide Autogel 120 mg every 4 weeks. Subjects in countries where lanreotide Autogel had not been approved for the treatment of carcinoid syndrome, who were well-controlled at the end of the 32-week IOL phase and chose to continue to receive lanreotide Autogel, were given the option of participating in a LTOLE phase. The LTOLE phase of the study was planned to end at least 2 years after the last subject had completed his/her participation in the 32-week IOL phase or when marketing approval for the treatment of symptoms of carcinoid syndrome had been obtained in the respective countries (whichever occurred first) or at any time the study was terminated by the Sponsor. The actual overall duration of the study was 6.5 years. During the LTOLE phase all subjects continued to be treated with lanreotide Autogel 120 mg every 4 weeks. The study planned to enrol approximately 100 adult subjects worldwide. Screening continued until 115 subjects were enrolled in the study.

Outcomes

What the study measures.

Primary outcomes

Percentage of Days With Subcutaneous Octreotide as Rescue Medication

Time frame · 16-week DB phase

Use of s.c. octreotide required to control symptoms associated with carcinoid syndrome, measured as the percentage of days that s.c. octreotide was used as rescue medication, based on subject Interactive Voice Response System (IVRS) or Interactive Web Response System (IWRS) diary records.

Secondary outcomes

Average Frequency of Diarrhoea Events (Per Day) Based on Subject Diary Records.

Time frame · 16-week DB phase

Average Frequency of Flushing Events (Per Day) Based on Subject Diary Records.

Time frame · 16-week DB phase

Percentage of Days of Use of Other Rescue Medication

Time frame · 16-week DB phase

Usage of other concomitant rescue medications for diarrhoea and/or flushing events, measured as the percentage of days that the medications were used as rescue medication based on subject IVRS/IWRS diary records. Subjects were required to record the use and dose of s.c. octreotide, if any, as well as the use of other concomitant rescue medications (e.g. loperamide 2 mg tabs, and/or tincture of opium).

Proportion of Subjects Who Rolled Over Into the IOL Phase Before Completing the DB Phase of the Study

Time frame · 16-week DB phase

Subjects who rolled over early were those who received less than four DB injections before receiving the first IOL injection.

Changes From Baseline in "Global Health Status/Quality of Life (QoL)" Score (Based on Items 29 and 30 of the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire [EORTC-QLQ] C30)

Time frame · Baseline and Week 12 of DB phase

Baseline is defined as the last non-missing observation obtained prior to the initiation of study treatment. Q29 and Q30 range from 1 (Very poor) to 7 (Excellent) with 1 being worst case and 7 the most favourable answer. Scores were derived according to the rules contained within the EORTC scoring manual. All of the scores range in score from 0 to 100. A high score for global health status/QoL represents high QoL. The principle for scoring the scale is: Estimate the average of the items (I1, I2, ..., In) that contribute to the scale; this is the raw score. Raw score = RS = (I1 + I2 +…+ In)/n. For global health status/QoL: Score = {(RS - 1)/range} x 100, where range is the difference between the maximum possible value of RS and the minimum possible value of RS.

Changes From Baseline in "Gastrointestinal (G.I). Symptoms" Subscore (Based on Items Q34, Q35, Q36, Q37 and Q38 of EORTC G.I. Neuroendocrine Tumour [NET] 21]

Time frame · Baseline and Week 12 of DB phase

Baseline is defined as the last non-missing observation obtained prior to the initiation of study treatment. The QLQ-G.I.NET21 questionnaire contains 21 single items (Q31 to Q51) which are supplemental items to the EORTC QLQ-C30 questionnaire. Q31 to Q51 range from 1 to 4 with 1 being the most favourable answer and 4 the worst case (1 = Not at all, 2 = A little, 3 = Quite a bit, 4 = Very much). Based on these items the scores were generated. All of the scores range in score from 0 to 100. A high score for a symptom scale represents a high level of symptomatology. The principle for scoring the scale is: Estimate the average of the items (I1, I2, ..., In) that contribute to the scale; this is the raw score. RS = (I1 + I2 +…+ In)/n. For symptom scales: Score = {(RS - 1)/range} x 100, where range is the difference between the maximum possible value of RS and the minimum possible value of RS.

Changes From Baseline in QoL in "Endocrine Symptoms" Subscore (Assessed Based on Items Q31, Q32 and Q33 Using EORTC QLQ-G.I.NET-21 Questionnaires)

Time frame · Baseline and Week 12 of DB phase

Baseline is defined as the last non-missing observation obtained prior to the initiation of study treatment. The QLQ-G.I.NET21 questionnaire contains 21 single items (Q31 to Q51) which are supplemental items to the EORTC QLQ-C30 questionnaire. Q31 to Q51 range from 1 to 4 with 1 being the most favourable answer and 4 the worst case (1 = Not at all, 2 = A little, 3 = Quite a bit, 4 = Very much). Based on these items the scores were generated. All of the scores range in score from 0 to 100. A high score for a symptom scale represents a high level of symptomatology. The principle for scoring the scale is: Estimate the average of the items (I1, I2, ..., In) that contribute to the scale; this is the raw score. RS = (I1 + I2 +…+ In)/n. For symptom scales: Score = {(RS - 1)/range} x 100, where range is the difference between the maximum possible value of RS and the minimum possible value of RS.

Absolute Changes From Baseline in Biochemical Markers (Plasma Chromogranin A [CgA])

Time frame · Baseline and Week 12 of DB phase

Baseline is defined as the last non-missing observation obtained prior to the initiation of study treatment.

Absolute Changes From Baseline in Biochemical Markers (Urinary 5-hydroxyindoleacetic Acid [5-HIAA])

Time frame · Baseline and Week 12 of DB phase

Baseline is defined as the last non-missing observation obtained prior to the initiation of study treatment.
