A Phase 1/2 Study to Evaluate CHM-2101, an Autologous Cadherin 17 Chimeric Antigen Receptor (CAR) T Cell Therapy

Recruiting now · Phase 1/Phase 2

Conditions studied: Neuroendocrine Tumors, Colorectal Cancer, Gastric Cancer

In brief

The goal of this clinical trial is to evaluate CHM-2101, an autologous CDH17 CAR T-cell therapy for the treatment of advanced gastrointestinal (GI) cancers that are relapsed or refractory to at least 1 standard treatment regimen in the metastatic or locally advanced setting.

Who can join

Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Documented informed consent of the participant and/or legally authorized representative.
• Confirmed histologic diagnosis of one of the following solid tumors of GI origin:
• Gastric adenocarcinoma Note: for gastric adenocarcinoma patients only, central laboratory confirmation of CDH17+ tumor expression is required.
• Colon and/or rectal adenocarcinoma
• G1, G2, and well-differentiated G3 neuroendocrine tumors of the midgut and hindgut (ileal, jejunal, cecal, distal colonic, or rectal; with ≤ 55% Ki67 expression)
• Availability of unstained tumor tissue slides from archived tumor tissue or a new tumor biopsy, if medically feasible. Note: for gastric adenocarcinoma patients only, confirmation of CDH17+ is required prior to study inclusion.
• Have received at least 1 prior line of systemic anti-cancer treatment in the locally advanced or metastatic setting, as defined by National Comprehensive Cancer Network (NCCN) guidelines. Participants must have received or declined FDA-approved and available treatment options, including targeted therapies for disease mutation or antigen expression status.
• Age ≥ 18 years and ≤ 85 years.
• For Phase 1 Dose Expansion and Phase 2 only: Measurable disease as per RECIST v1.1 criteria (Note: Measurable disease is NOT required for Phase 1 Dose Escalation).
• Eastern Cooperative Oncology Group (ECOG) ≤ 1.
• Life expectancy ≥ 12 weeks.
• No known contraindications to leukapheresis, cyclophosphamide, fludarabine, or steroids.
• Baseline laboratory values as shown in the following table:
• Minimum Laboratory Values for Study Entry Laboratory Assessment Criteria White blood cell count > 4,000/mm3 Absolute neutrophil count (ANC) ≥ 1,500/mm3 Platelets ≥ 100,000/mm3 Hemoglobin ≥ 10 g/dL Total bilirubin ≤ 1.5 x upper limit of normal (ULN) Aspartate amino transferase (AST) ≤ 3 x ULN Alanine transaminase (ALT) ≤ 3 x ULN Creatinine clearance by Cockroft-Gault equation 60 mL/min Oxygen saturation ≥ 92% on room air Albumin ≥ 3 g/dL
• Left ventricular ejection fraction ≥ 50%.
• Seronegative for human immunodeficiency virus (HIV) by antigen/antibody (Ag/Ab) testing.
• Seronegative for hepatitis B and/or hepatitis C virus.
• Women of childbearing potential (WOCBP) must have a negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test is required.
• Agreement by women and men of childbearing potential to use an effective method of birth control or abstain from heterosexual activity through at least 3 months after the last dose of CHM-2101.

You may not qualify if…

• Previous treatment with CDH17-targeted therapies.
• Unresolved toxicities from prior therapy except for chronic toxicity no greater than Grade 1 and stable > 30 days (Note: alopecia of any grade is not exclusionary).
• Uncontrolled seizure activity and/or known central nervous system (CNS) metastases.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to study agent.
• Uncontrolled Crohn's disease, ulcerative colitis, or other autoimmune or inflammatory disorders of the GI tract. "Uncontrolled" is defined as requiring hospitalization, corticosteroids, or chronic medication increase (dosage or frequency) within the previous 6 months.
• Liver involvement ≥ 50%.
• Active infection requiring oral or IV antibiotics.
• Current diagnosis of pleural effusions, interstitial lung disease, or heart failure of New York Heart Association Classification of Heart Failure Class III or IV.
• Ongoing treatment with systemic corticosteroid therapy at doses of prednisone ≥ 20 mg/day or equivalent (lower doses of corticosteroid therapy are allowed until 7 days prior to leukapheresis).
• No prior malignancy within 5 years except for non-melanomatous skin cancer or cervical cancer treated with curative intent
• Currently breastfeeding or planning to become pregnant within 9 months of study enrollment.
• Any other clinically significant uncontrolled illness or other comorbid condition that would, in the investigator's judgment, contraindicate the participant's participation in the clinical study.
