Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This clinical study is aimed to evaluate the efficacy of a new food supplement called "Amixea" in improving muscle strength and body composition in cancer patients, when compared to placebo.
Amixea is a mixture of amino acids. It consists mainly of essential amino acids (EAA).

List of characterizing ingredients in Amixea:

L-leucine
L-lysine chloride
L-isoleucine
L-valine
L-threonine
L-histidine chloride monohydrate
L-cystine
L-phenylalanine
L-methionine
L-tyrosine
L-tryptophan


Each sachet will be of 6.6 mg (including active ingredients abov listed and excipients).
Amixea will be administered orally for 10 weeks: 3 sachets per day. Each sachet will be taken with approximately 150 ml of chilled water, 30 minutes after food.

The patients’ compliance to the treatment will be checked by the study staff by counting the number of used and unused sachets returned by the patients at Visit 3 and 4.

Sample size determination:
According to the literature, the expected mean fat free mass (FFM) as measured by DXA in the control group could be 49.06 kg, with a standard deviation of 10.38. Assuming that the minimum difference of interest between the comparison groups is 15%, the study group is expected to obtain a mean FFM of 56.42 kg. Under this hypothesis and considering a common standard deviation (ie. 10.38), 40 subjects per group (80 total subjects) will be required to detect this difference with 80% power, considering an alpha of 0.025 (two-tailed), to account for the two primary endpoints.
The literature review didn't provide data on quadriceps maximal voluntary contraction (QVMC) among lung cancer that enabled formal estimation of the sample size. However, with 80 subjects, a difference of 7 kg between the two treatment groups can be assessed with a power higher than 80%, considering an alpha of 0.025 and a common standard deviation of 9 kg.
Assuming a refusal rate of 20%, an attrition rate of 40% and allowing 15% extra for probable need to apply multivariable modelling techniques to adjust for confounding, we would need to approach 200 patients to enroll at least 160 subjects enabling 80 valid subjects at the end of the study. This sample size would be necessary not to lose the opportunity to detect clinically relevant differences in all primary and secondary outcomes.

Primary outcomes analysis:
For both continuous primary outcome variables, ANCOVA will be used to evaluate whether outcome means are equal between Amixea and control groups at 10 weeks while controlling for the effects of covariates including baseline values.
The improvement of lean body mass will be assessed by DXA. The improvement of QMVC force will be assessed by dynamometer.

Secondary outcomes analysis:
For all continuous secondary outcome variables, ANCOVA will be used to evaluate whether outcome means are equal between Amixea and control groups at 10 weeks while controlling for the effects of covariates including baseline values.
For categorical secondary outcome variables (i.e., PGSGA ratings), chi squared test will be used to evaluate the sampling distribution between Amixea and control groups at 10 weeks.
Energy-yielding metabolites will be analysed using overnight fasted blood metabolites.
Nutrition status will be assessed using global PG-SGA rating.
Nutrition risk will be assessed using PG-SGA score. Health Related Quality of Life (HRQoL) will be assessed using FAACT. Skeletal muscle mass area from L3 will be assessed in a subsample of patients who have CT scans within the prescribed timeframes.

Safety oucomes analysis:
Adverse events will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) to give a preferred term (PT) and a system/organ class term (SOC) for each event. The number of patients who experienced at least one AE, trial product-related AE, serious AE, severe AE and the number of patients withdrawn due to AE will be summarized by treatment arm.
Descriptive analysis of vital signs will be performed by treatment group and changes from baseline will be analyzed within each treatment group using paired T-test. Comparisons between treatment groups will be performed using ANOVA.

Exploratory outcomes evaluation:
The adherence to the assigned treatment will be assessed by sachet count at Visits 3 and 4. The percentage of treatment correctly assumed will be estimated and compared by treatment group using Student’s T-test.
Patient satisfaction will be assessed by a Likert Scale. The patient satisfaction will be compared by treatment group using t-test for normally distributed data or Mann-Whitney U test for non-normally distributed data, as appropriate.

Population analysed:
The intention to treat (ITT) and per protocol (PP) populations will be analysed under the following conditions:
- If less than 20% of the data are missing; both PP and ITT analyses will be conducted.
- If more than 20% of the data are missing; only a PP analysis will be conducted.
The ITT population will be used to evaluate the effectiveness of the treatment in the clinical setting. That is, all randomized patients will be included in the analysis. Any missing data will be coded as missing at random (MAR) or not missing at random (NMAR) and imputed using multiple imputation techniques.

The PP population will be used to evaluate the efficacy of the treatment. That is, all patients who have completed the entire treatment protocol as originally planned and with perfect compliance will be included in the analysis.
