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.

Percentage of Participants Developing Diarrhea (Grade 1 to 4)
6 month overall

The percentage of patients developing diarrhea (incidence of grade 1 to 4) during treatment, considering only the worst grade of diarrhea for each patient. Diarrhea was graded according to Common Toxicity Criteria where Grade 0=None, 1 = Increase of \<4 stools/day over pretreatment, Grade 2 = Increase of 4-6 stools/day, or nocturnal stools, Grade 3 = Increase of ≥7 stools/day or incontinence; or need for parenteral support for dehydration and Grade 4= Physiologic consequences requiring intensive care; or hemodynamic collapse.

Mean GH and IGF-I at baseline, week 12, 24 and 48
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.

Frequently asked questions about Octreotide Long Acting Release

What is Octreotide Long Acting Release?

Octreotide Long Acting Release is an injectable somatostatin analog developed by Novartis AG (ticker NVS). It is being studied in Phase 3 clinical development for chemotherapy-induced diarrhea, a gastrointestinal condition in which cancer treatment causes frequent loose stools. The long acting release formulation is designed to provide sustained drug exposure after administration.

What is Octreotide Long Acting Release used for in chemotherapy-induced diarrhea?

Octreotide Long Acting Release is being evaluated for the prevention of chemotherapy-induced diarrhea in adults aged 18 years and older. A completed Phase 3 trial, NCT00582426, studied the drug for this indication in Brazil with 139 enrolled patients. It remains an investigational use rather than an established approved indication.

What does Octreotide Long Acting Release target?

Octreotide Long Acting Release is an agonist that binds somatostatin receptors, specifically SSTR1, SSTR2, SSTR3, SSTR4, and SSTR5. Its highest affinity is for SSTR2 and SSTR5. Activation of these receptors reduces secretion and smooth muscle activity in the gastrointestinal tract, which is the basis for its study in chemotherapy-induced diarrhea.

Who makes Octreotide Long Acting Release?

Novartis AG, which trades under the ticker NVS, is the developer of Octreotide Long Acting Release. The company is responsible for the clinical program evaluating the drug in chemotherapy-induced diarrhea.

What phase is Octreotide Long Acting Release in?

Octreotide Long Acting Release is in Phase 3 clinical development for chemotherapy-induced diarrhea. The program includes one completed Phase 3 trial, and no trials are currently listed as active. The drug is investigational for this indication and has not been established as approved for chemotherapy-induced diarrhea.

What clinical trials is Octreotide Long Acting Release in?

Octreotide Long Acting Release has been studied in the Phase 3 trial NCT00582426, titled Evaluation of Octreotide LAR in Prevention of Chemotherapy-induced Diarrhea. The trial enrolled 139 adults aged 18 years and older in Brazil, used a controlled and randomized design, and has been completed.
