Study Endpoints

Primary Endpoints

Change from Baseline in muscle derived protein synthesis rate
Baseline and Day 21

Muscle protein synthesis will be assessed by measuring the fractional synthetic rate of muscle-derived proteins in both muscle biopsy samples and in blood after subjects have ingested deuterated water. The FSR of several muscle-derived proteins will be analyzed at baseline and during the period of testosterone treatment using deuterium labelling of these proteins by the incorporation of deuterium from D2O.

Secondary Endpoints

Change from Baseline in lower extremity strength using the 1-repetition maximum (1-RM) leg strength, FSRs from muscle proteins derived from muscle biopsies and serum samples
Baseline, Day 7, 14, and 21
Changes in FSR in muscle and serum derived muscle proteins

Treatment Arms

ArmTypeDescription
Arm 1EXPERIMENTALRun-in Phase: All participants will receive oral deuterated water (D2O) for 3 weeks prior to the Treatment Phase of the study. The participants will consume 50mL 70% D2O three times per day (TID) for 7 days, followed by a 50ml 70% D2O dose twice daily (BID) for the next 2 weeks. Treatment Phase: Subjects will receive testosterone matching placebo IM injection one per week and 50 mL 70% D2O dose BID for 3 weeks.
Arm 2PLACEBO_COMPARATORRun-in Phase: All participants will receive oral D2O for 3 weeks prior to the Treatment Phase of the study. The participants will consume 50 mL 70% D2O TID for 7 days, followed by a 50mL 70% D2O dose BID for the next 2 weeks. Treatment Phase: Subjects will receive testosterone IM injection one per week and 50 mL 70% D2O dose BID for 3 weeks

Frequently asked questions about Deuterated Water

What is Deuterated Water used for?

Deuterated Water is an investigational small molecule being studied for cachexia, a condition of severe weight loss and muscle wasting. It is in Phase 1 clinical development. The drug is being evaluated in a clinical trial that includes healthy male volunteers aged 60 years and older.

Who makes Deuterated Water?

Deuterated Water is being developed by GSK plc, a biopharmaceutical company. GSK's ticker symbol is GSK. The drug is currently in Phase 1 clinical development for cachexia.

What phase is Deuterated Water in?

Deuterated Water is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. One Phase 1 trial has been completed, and the drug is not yet available for clinical use.

What clinical trials is Deuterated Water in?

Deuterated Water has one completed clinical trial, NCT01962454, titled "A Study to Evaluate a Skeletal-muscle Microbiopsy Technique With Dynamic Proteomic Measurement in Healthy Male Volunteers." The trial enrolled 20 participants in the United States and was placebo-controlled.

Is Deuterated Water the same as heavy water?

Deuterated Water is a form of water in which the hydrogen atoms are replaced by deuterium, a heavier isotope of hydrogen. It is sometimes referred to as heavy water. In the context of this clinical development, it is being studied for its potential effects on cachexia.
