Scientific title	A prospective randomised controlled phase III trial of gemcitabine and docetaxel compared with doxorubicin as first line treatment in previously untreated advanced unresectable or metastatic soft tissue sarcomas
Study acronym	GeDDiS
Study hypothesis	The proposed study aims to determine whether the combination of gemcitabine and docetaxel is associated with an improved clinical outcome compared with single agent doxorubicin.
Ethics approval(s)	Central London REC 2, Royal Free Hospital, London, 11/08/2010, ref: 10/H0713/54
Condition	Soft tissue sarcomas
Intervention	Standard arm: doxorubicin 75 mg/m^2 day 1 every three weeks for up to 6 cycles. Experimental arm: gemcitabine 675 mg/m^2 days 1 and 8, docetaxel 75 mg/m^2 day 8 every three weeks for up to 6 cycles with granulocyte-colony stimulating factor (GCSF) support days 8 - 15. Both arms consist of six, three weekly cycles, a total of 18 weeks of treatment. Following treatment, patients will be followed up two monthly with clinical evaluation and scanning until disease progression, or death.
Intervention type	Drug
Pharmaceutical study type(s)
Phase	Phase III
Drug / device / biological / vaccine name(s)	Gemcitabine, docetaxel, doxorubicin
Primary outcome measure	Progression-free survival, assessed using the RECIST Criteria every six weeks (after each set of two cycles); following treatment assessment will be 2-monthly.
Secondary outcome measures	1. Overall survival, time to progression and objective response rate assessed using the RECIST Criteria every six weeks (after each set of two cycles); following treatment assessment will be 2-monthly 2. Toxicity, continuously assessed and recorded using the NCI Common Terminology Criteria for Adverse Events v4.0 3. Quality of life, measured using the EORTC QLQ C30 for patients aged 16 years and greater and the PEDQOL questionnaire for patients aged less than 15 years. The EQ5D will also be used for health economic evaluation. Measured at baseline, prior to cycle 3 (6 weeks), prior to cycle 6 (15 weeks) and six weeks after the completion of treatment.
