Brief Summary:
This study is an open label, multicenter study in patients who have advanced, relapsed refractory GI cancer or are not relapsed/refractory but are intolerant to other therapies who, in the judgment of investigators, are candidates for fluoropyrimidine monotherapy.

Arm Intervention/treatment
Experimental: PCS6422 + Capecitabine
Fixed dose of PCS6422 combined with various doses of Capecitabine administered in 14 day cycles
Drug: PCS6422 and capecitabine
PCS6422 is an experimental drug that, when combined with capecitabine, may make the immune response more active against cancer. Capecitabine is a commonly used oral fluoropyrimidine.




Primary Outcome Measures :
  1. Number of participants with treatment-emergent Adverse Events as assessed by CTCAE v5.0 [ Time Frame: ~6 months ]
    Frequency, duration, and severity of treatment-emergent adverse events (AEs)

  2. Maximum Plasma Concentration (Cmax) of capecitabine [ Time Frame: ~14 days ]
    To evaluate the Maximum Plasma Concentration (Cmax) of capecitabine

  3. Maximum Plasma Concentration (Cmax) of PCS6422 [ Time Frame: ~14 days ]
    To evaluate the Maximum Plasma Concentration (Cmax) of PCS6422


Secondary Outcome Measures :
  1. Number of participants with Adverse Events of Special Interest as assessed by CTCAE v5.0 [ Time Frame: ~6 months ]
    Frequency, duration, and severity of adverse events of special interest (AESIs)
