Overview
Brief Summary
This is a randomised, double-blind, placebo-controlled, therapeutic confirmatory multicentre trial with 4 parallel treatment groups. The design is adaptive group-sequential with two interim analyses, possible sample size re-estimation after the first or second interim analysis and drop-the-loser approach. The study design was primarily chosen to show superior efficacy of Tepilta® compared to the single components and to placebo. Evaluation of safety is a secondary objective.
Detailed Description
Tepilta® Suspension is indicated for treatment of pain in the upper digestive system induced by radiation therapy, in particular for radiation-induced oesophagitis.

Eligibility Criteria
Inclusion Criteria
- •Male or female ≥ 18 years.
- •Score = 0 on NRS for oesophageal pain.
- •Radiotherapy (RT) or combined radio-chemotherapy (RCT) of a solid tumour in head/neck/thorax region. A minimum length of 5 cm of the oesophagus must be included in high-dose radiation field.
- •Duration of RT 5 to 8 weeks.
- •Single radiation dosage of fractionated RT 1.8 to 2.0 Gy/day, of intensity-modulated RT (IMRT) 1.5 to 2.3 Gy/day, each for 5 days a week (single frequency deviations are allowed presuming that intended duration of RT remains 5 to 8 weeks).
- •First radiation in the intended radiation area.
- •Written informed consent.
- •Randomisation criteria:
- •Appearance of oesophageal pain as follows: Score ≥ 2 on Numeric Rating Scale (NRS) for pain during main daily meals is reached at least once.
- •At least 20 Gy of the dose of radiation therapy in oesophageal area remaining.
Exclusion Criteria
- •History of allergic reaction to the study medication or its excipients (i.e. aluminium or magnesium hydroxide, oxetacaine, any other ingredient of study medication).
- •Pregnancy, breast-feeding or planned pregnancy during the study.
- •Known hypermagnesaemia.
- •Known hypophosphataemia.
- •Clinically significant obstipation, as judged by the investigator.
- •Acute appendicitis.

- •Hyper-fractionated RT.
- •Intended naso-gastral tubes.
- •Primary tumour of the cranial base, brain, oral cavity, lips, naso-pharynx, para-nasal sinuses.
