Outcome Measures

Primary Outcomes (1)

  • Number of participants that experienced a shift in bacterial community assessed by operational taxonomic units

    Shifts in the bacterial communities is based on clustering of operational taxonomic units (OTU) at 97% similarity

Study Arms (2)

Arm I (glucosamine sulfate/chondroitin sulfate tablet)

EXPERIMENTAL

Patients receive glucosamine sulfate/chondroitin sulfate tablet PO on days 1-14 in the absence of disease progression or unacceptable toxicity. Fourteen days later, patients crossover to Arm II.
