Background and study aims
Food intolerance and lactose intolerance have common symptoms. Food intolerance, also known as non-IgE mediated food hypersensitivity or non-allergic food hypersensitivity, refers to a difficulty in digesting certain foods. In food intolerance, people can tolerate different amounts of the food, but when they eat too much (or too often) they get symptoms because their body cannot tolerate unlimited amounts. Symptoms such as fatigue, joint pains, dark circles under the eyes, night sweats, gastrointestinal symptoms such as diarrhoea and vomiting, bloating, irritable bowel, skin symptoms such as rashes, eczema are most common symptoms of food intolerance.
Lactose intolerance is the inability or the insufficient ability to digest lactose. It develops naturally as people grow older as the small intestine produces less lactase (which breaks down lactose). Certain digestive diseases such as irritable bowel syndrome, Crohn's disease, celiac disease (a digestive disease that damages the small intestine and interferes with absorption of nutrients from food), infections, and injuries to the small intestine can also reduce the amount of lactase available to process lactose properly.
It is not easy to initially determine whether an individual has a food intolerance or allergy because the signs and symptoms often overlap between food intolerance, lactose intolerance and food allergy.
Apart from lactose intolerance there is no accurate, reliable and validated test to identify food intolerance and usually the treatment consists of exclusion diets (removing certain foods from the diet). Lactose intolerance is also responsible for food intolerance. Maintaining tolerance is often a question of knowing how long to abstain, and how much of it to eat when it is being reintroduced
A diagnosis of food intolerance may be difficult and based on dietary exclusion. A number of methods are available but the lactose breath hydrogen test is considered a very simple, useful and most reliable test in subjects with suspected lactose intolerance. Recently a new genetic test has been proposed, complementing the role of breath testing.
Novintethical Pharma SA has developed a new formulation for treating the symptoms of lactose intolerance and intolerance called Lactosectan. It is intended for the reduction of the symptoms secondary to lactose maldigestion, reducing the discomfort related to lactose intake, such as bloating, flatulence, and abdominal pain. It is also thought to protect the intestinal lining.
The aim of this study is to assess the effectiveness of Lactosectan at reducing the symptoms of lactose intolerance in adult patients.

Who can participate?
Patients aged 18 to 64 years with a current or recently reported history of lactose intolerance of at least 1-month duration.

What does the study involve?
Participants are randomly allocated to take Lactosectan or a placebo orally three times per day for 7 days, then they swap and take the other treatment for 7 days. They will keep a journal with the type and quantities of the dairy products they consume over the treatment period. They will be advised not to consume more than 500 ml of dairy products per day.

What are the possible benefits and risks of participating?
This treatment could be very helpful for treating and relieving the symptoms of lactose intolerance or the inability to digest lactose. If no results are obtained according to the treatment plan, a gastroenterologist will decide whether or not to continue the treatment. There are no expected risks.

Where is the study run from?

Study acronymEFFECT
Study objectivesThis is a Phase IV, double-blind, cross-over, randomized, and parallel multicenter study to evaluate the safety and efficacy of LTS035 (Lactosectan) vs. placebo in adult patients with intolerance to certain foods, primarily lactose intolerant.
Ethics approval(s)Approved 28/11/2016, National Commission for Bioethics of Medicines and Medical Devices (Comisia Nationala de Bioetica a medicamentului si a Dispozitivelor Medicale, Stefan Cel Mare 19-21 Road, District 2, Bucharest, Romania; +40 (0)212102880; comisia.bioetica@adsm.ro), ref: 8DM/28.09.2016
Health condition(s) or problem(s) studiedLactose intolerance
InterventionSubjects meeting all eligibility criteria will be randomized using a 1:1 ratio (Lactosectan: placebo) based on the randomization sequence and documented in the study file.

Group A will receive treatment A for 7 days, and group B will receive treatment B for 7 days. After 7 days the groups cross over: group A will receive treatment B for the other 7 days, and group B will receive product A for another 7 days.

The treatments (Product A or Product B) will be administered by the oral route. During the 14-day treatment period, all subjects will be asked to keep a daily journal of the type and quantities of the dairy products they consume. All subjects will be advised not to consume more than 500 ml of dairy products per day.

Visit 1 - Patients will sign the informed consent form and they will undergo hydrogen breath tests (HBT)
Visit 2 - HBT test, randomization, treatment allocation, Group A will receive product A, Group B will receive product B
Visit 3 - HBT test to test the speed of action
Visit 4 - Group A will finish the treatment with product A according to the leaflet and Group B will finish treatment with product B, and crossover to the second line of treatment (Group A will receive product B and Group B will receive product A)
Visit 5 - HBT test to test the speed of action
Visit 6 - HBT final test
Intervention typeDevice
Pharmaceutical study type(s)
PhasePhase IV
Drug / device / biological / vaccine name(s)Lactosectan
Primary outcome measureEfficacy evaluated in terms of:
1. Tolerability of food intake assessed using a daily journal kept for the entire period of the study treatment
2. Symptom reduction (bloating, distension, pain) assessed by the Likert scale using a daily journal kept for the entire period of the study treatment
3. Speed of action assessed using the hydrogen breath test (HBT) on V2 (day 1 of treatment), V3 (day 2 of treatment), V4 (end of first-line treatment and crossover) to V5 (after cross-over the first day of the second-line treatment)
Secondary outcome measuresThe safety of the LTS035 study formulation evaluated by monitoring the occurrence of undesirable effects reported by the patient or observed by the physician during the whole study period
