Monoclonal Antibody Therapy in Treating Patients With Advanced Colorectal Cancer

October 2, 2023 updated by: Ludwig Institute for Cancer Research

Phase I Study of Humanized 3S193 (Anti-Lewis-Y) Antibody in Patients With Advanced Colorectal Carcinoma

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.

PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have advanced colorectal cancer.

Detailed Description

OBJECTIVES:

  • Determine the toxicity, maximum tolerated dose, and pharmacokinetics of monoclonal antibody hu3S193 in patients with advanced colorectal carcinoma.
  • Determine the immune response in these patients treated with this regimen.

OUTLINE: This is a dose escalation study.

Patients receive monoclonal antibody hu3S193 (mAb hu3S193) IV over 30 minutes to 4 hours weekly for 8 weeks followed by 2 weeks of rest. Patients with stable or responding disease at week 10 receive maintenance mAb hu3S193 weekly. Courses repeat every 8 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of mAb hu3S193 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 3 of 6 patients experience dose limiting toxicities.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Hu3S193 10 mg/m2
Hu3S193 was administered weekly for 8 consecutive weeks. The antibody was diluted in physiologic saline containing 5% human serum albumin and infused intravenously at a maximum rate of 100 mg/hour. If patients were stable or responding, they were eligible to receive 8-week maintenance cycles of hu3S193 at 10 mg/m2 starting in week 10 and continuing until progression.
Experimental: Hu3S193 25 mg/m2
Hu3S193 was administered weekly for 8 consecutive weeks. The antibody was diluted in physiologic saline containing 5% human serum albumin and infused intravenously at a maximum rate of 100 mg/hour. If patients were stable or responding, they were eligible to receive 8-week maintenance cycles of hu3S193 at 10 mg/m2 starting in week 10 and continuing until progression.
Experimental: Hu3S193 50 mg/m2
Hu3S193 was administered weekly for 8 consecutive weeks. The antibody was diluted in physiologic saline containing 5% human serum albumin and infused intravenously at a maximum rate of 100 mg/hour. If patients were stable or responding, they were eligible to receive 8-week maintenance cycles of hu3S193 at 10 mg/m2 starting in week 10 and continuing until progression.
Experimental: Hu3S193 100 mg/m2
Hu3S193 was administered weekly for 8 consecutive weeks. The antibody was diluted in physiologic saline containing 5% human serum albumin and infused intravenously at a maximum rate of 100 mg/hour. If patients were stable or responding, they were eligible to receive 8-week maintenance cycles of hu3S193 at 10 mg/m2 starting in week 10 and continuing until progression.
Experimental: Hu3S193 200 mg/m2
Hu3S193 was administered weekly for 8 consecutive weeks. The antibody was diluted in physiologic saline containing 5% human serum albumin and infused intravenously at a maximum rate of 100 mg/hour. If patients were stable or responding, they were eligible to receive 8-week maintenance cycles of hu3S193 at 10 mg/m2 starting in week 10 and continuing until progression.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Patients With Dose-limiting Toxicities (DLTs)
Time Frame: up to 10 weeks.
Toxicity was graded in accordance with the Common Toxicity Scale developed by NCI (1998) where Grade 1 represents the lowest toxicity grade and Grade 5 death. Dose-limiting toxicity (DLT) was defined as Grade 3 and Grade 4 adverse events which were at least possibly related to study treatment.
up to 10 weeks.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Patients With Tumor Responses
Time Frame: 8 weeks
Complete response (CR); disappearance of all measurable disease lasting a minimum of 4 weeks. Partial Response (PR); 50% or greater decrease in the sum of the products of the perpendicular diameters or all measurable lesions, without development of new lesions or increase in size of any lesion, lasting a minimum of 4 weeks. Progressive disease (PD); Appearance of new lesions or increase by 25% or more in size of any measurable lesion. Stable disease (SD); Not meeting criteria for response or progression.
8 weeks
