Definitions
- the invention relates to a new medical use for alosetron, a compound which act as an antagonist of 5-hydroxytryptamine (5-HT) at 5-HT 3 receptors.
- Alosetron is known to be useful for the treatment of a variety of conditions, including irritable bowel syndrome.
- PCT Publication No. WO 99/17755 published 15 April 1999, incorporated herein by reference, in particular discloses the use of alosetron and other
- 5-HT3 receptor antagonists for the treatment of irritable bowel syndrome in females. It has now been discovered that alosetron is useful for the treatment of functional (or "nonulcer") dyspepsia.
- Functional dyspepsia is a distinct type of dyspepsia.
- the term "dyspepsia” is defined as the general condition of indigestion and as such encompasses a variety of distinct dyspeptic conditions.
- There are several recognized types of dyspepsia the most common being acid-related dyspepsia which is associated with excess gastric acidity and may lead to peptic ulcers, gastroesophageal reflux disease (GERD), and other conditions characterized by excess gastric acidity.
- Functional dyspepsia (FD) is not associated with excess gastric acidity. Rather, the primary pathophysiological causative factor for FD is unclear.
- FD is a visceral hypersensitivity state characterized by chronic or recurrent upper abdominal symptoms in the absence of any identifiable organic pathology, such as peptic ulceration, gastric cancer, chronic pancreatitis or GERD.
- identifiable organic pathology such as peptic ulceration, gastric cancer, chronic pancreatitis or GERD.
- the absence of identifiable organic pathology is established using conventional techniques including endoscopy, radiography, histology, and other techniques known to those skilled in the art.
- the primary symptoms of FD include upper abdominal pain or discomfort (often aggravated by food or milk or occurring after meals), early satiety (which can lead to weight loss or anorexia), nausea and vomiting, bloating, belching, and post-prandial fullness.
- FD has been divided into subtypes based upon the predominant symptom(s) observed in the patient.
- "Ulcer-like” FD is characterized primarily by pain.
- "Reflux-like” FD is primarily characterized by heartburn that is often alleviated by acid-suppressing agents. It is believed that most cases of reflux-like FD can actually be attributed to GERD, and is not actually FD because the condition can be associated with an organic pathology.
- “Dysmotility-like” FD is characterized primarily by discomfort, bloating, nausea, vomiting, early satiety, and post-prandial fullness.
- "Unspecified” FD refers to FD patients having symptoms that do not fit into the above categories. Typically FD patients exhibit symptoms across the various sub-types.
- Symptoms exhibited by many FD patients have traditionally been erroneously associated with acid-related dyspepsia (i.e., heartburn, reflux of acid, etc.) and as a result antisecretory agents have been evaluated for their applicability in the treatment of FD.
- Efficacy studies with histamine H-2 receptor antagonists have produced conflicting results; several studies having failed to demonstrate an effect different from placebo.
- Patients with ulcer-like FD or coexistent symptomatic GERD were the most likely to respond positively to treatment with an H-2 receptor antagonist.
- the present invention provides a method for treatment of functional dyspepsia comprising administering an effective amount of alosetron or a pharmaceutically acceptable derivative thereof.
- the present invention provides a method of treatment for functional dyspepsia in females comprising administering an effective amount of alosetron or a pharmaceutically acceptable derivative thereof.
- the present invention provides a method of treatment for functional dyspepsia in subjects having normal gastric emptying comprising administering an effective amount of alosetron or a pharmaceutically acceptable derivative thereof.

- effective doses for the treatment of FD, the treatment of FD in females, and the treatment of FD in subjects with normal gastric emptying will lie in the range of 0.001 to 500mg, such as 0.01 to 100mg, preferably 0.05 to 50mg, for example 0.5 to 25mg per unit dose, which could be administered in single or divided doses, for example, 1 to 4 times per day.
- effective doses of alosetron for the treatment of FD, the treatment of FD in females, and the treatment of FD in subjects with normal gastric emptying will lie in the range of 0.01 to 100mg, such as 0.05 to 50mg, preferably 0.1 to 25mg, for example 0.5, 1 , 2 or 4mg of alosetron per unit dose, which could be administered in single or divided doses, for example, 1 to 4 times per day.
- 0.5 mg of alosetron is administered twice per day.
- 1 mg of alosetron is administered twice per day.
- 2 mg of alosetron is adminstered once per day.
- Three hundred and twenty (320) ambulatory outpatient male and female FD patients at least 18 years of age who have chronic or recurrent abdominal pain or discomfort centered in the upper abdomen were randomised for study comprising twelve (12) weeks of treatment: eighty one (81) were randomised to treatment with placebo BID, seventy seven (77) to 0.5 mg BID alosetron, seventy nine (79) to 1 mg BID alosetron, and eighty three (83) to 2 mg BID alosetron.
- Study participants included patients who have been diagnosed with FD and patients with symptoms that fulfilled the modified Rome criteria for FD for at least 6 months. Study participants were screened for two weeks prior to the testing phase, to confirm symptoms of sufficient severity for participation in the study.
- the primary endpoint was adequate relief of FD (upper abdominal) pain or discomfort.
- Secondary endpoints included 1) changes in daily upper abdominal pain severity ratings, 2) proportion of pain free days, 3) changes in self-ratings of nausea, early satiety, bloating or distension, post-prandial fullness and burping or belching, 4) changes in quality of life (Q0L) SF-36 scores, 5) changes in SCL-90R® scores, and 6) safety and tolerability with respect to the incidence of adverse events and changes in laboratory values.
- Subjects also responded daily to yes/no questions assessing whether early satiety, postprandial fullness and burping or belching were present.
- a "completed subject" is one who completed the screening phase, treatment phase and one-week follow-up phase of the study. Subjects who did not complete the three phases of the study were considered prematurely discontinued and were not replaced.
- the number of subjects per treatment group needed to detect a 20% difference in proportion of patients with adequate relief between alosetron and any dose of alosetron was 64 per group, assuming the proportion with adequate relief in the placebo group was 35%.
- a target sample size of 70 patients per treatment group was chosen to allow for an approximate 10% dropout rate.
- ITT Intent-to-Treat
- LOCF last observation carried forward
- Secondary efficacy measures included subject self-rating of pain severity, frequency and the FD symptoms of nausea, bloating/distension, burping/belching, early satiety and postprandial fullness.
- the percentage of pain-free days, days with nausea, bloating/distension, early satiety, post-prandial fullness and burping/belching were calculated at baseline (for the 2 week screening period), and for each week of the treatment and follow-up phases.
- average severity of pain, nausea and bloating/distension were calculated at baseline and for the same weekly intervals. For each parameter, changes from baseline in treatment groups were compared using a Wilcoxon rank sum test stratified by geographical cluster.
- Adverse events were coded and group by body system. Adverse events occurring after randomization were summarized separately from adverse events occurring during the screening phase. For each body system and over all body systems, the frequency of subjects reporting at least one adverse event was calculated by treatment group. In addition, the number of subjects reporting at least one drug-related adverse event and the number of subjects reporting serious adverse events were summarized by treatment group. The four treatment groups were compared using a correlation chi-square test; pairwise comparisons were made with Fisher's exact test.
- alosetron substantially improved abdominal pain and discomfort in FD patients, particularly female FD patients.
- Alosetron also substantially improved nausea, early satiety and post-prandial fullness in female patients and patients with normal gastric emptying.
- alosetron is an effective and well-tolerated therapy for the treatment of FD patients.
- the use of alosetron for the treatment of functional dyspepsia shows unexpected benefits in female patients.
