Interventions
Living bioengineered, non-genetically manipulated, activated Th1-like immune cells differentiated and expanded from precursor cells purified from blood of healthy unrelated donors
Eligibility Criteria
You may qualify if:
- Adult males and female subjects aged 18-80 years at screening visit
- Pathologically confirmed diagnosis of colorectal adenocarcinoma
- Presenting with metastatic disease:
- Previous treatment failure of two previous lines of active systemic chemotherapy:
- Previous chemotherapy must have included an oxaliplatin-containing (e.g. FOLFOX) and an irinotecan-containing (e.g. FOLFIRI) regimen
- With or without bevacizumab
- Administered in adjuvant setting or for treatment of metastatic disease
- If KRAS wild type, must have at least one prior anti-EGFR therapy
- Treatment failure can be due to disease progression or toxicity
- Disease progression on second line therapy must be documented radiologically and must have occurred during or within 30 days following the last administration of treatment for metastatic disease
- ECOG performance score: 0-1
- Adequate hematological function:
- Absolute granulocyte count ≥ 1,200/mm3
- Platelet count ≥ 100,000/mm3
- PT/INR ≤ 1.5 or correctable to \<1.5 at time of interventional procedures
- +11 more criteria
You may not qualify if:
- high frequency microsatellite instability (MSI-H)
- Bowel obstruction or high risk for obstruction if tumors become inflamed
- Moderate or severe ascites requiring medical intervention
- Clinical evidence or radiological evidence of brain metastasis or leptomeningeal involvement
- Peritoneal carcinomatosis
- Symptomatic asthma or COPD
- Pulmonary lymphangitis or symptomatic pleural effusion (grade ≥ 2) that results in pulmonary dysfunction requiring active treatment; or, oxygen saturation \<92% on room air
- Bevacizumab (Avastin®) treatment within 6 weeks of baseline scheduled biopsy procedure
- Any of the following mood disorders: active major depressive episode, history of suicidal attempt or ideation
- Prior allogeneic bone marrow/stem cell or solid organ transplant
- Chronic use (\> 2 weeks) of greater than physiologic doses of a corticosteroid agent (dose equivalent to \> 5 mg/day of prednisone) within 30 days of the first day of study drug treatment
- Topical corticosteroids are permitted
- Prior diagnosis of an active autoimmune disease (e.g., rheumatoid arthritis, multiple sclerosis, autoimmune thyroid disease, uveitis).
- Well controlled Type I diabetes allowed
- Prior experimental therapy
- +9 more criteria
