NCT04444622

Brief Summary

This is a Phase IIB multi-site, open label study of a next generation immunotherapy for third-line MSI-S metastatic colorectal cancer using an "off-the-shelf", non-genetically manipulated living immune cell product (AlloStim) derived from the blood of healthy donors.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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
