Experiment 1 Reporting the Activity Date of This ADC [1]
Patients Enrolled
Eligible patients must have histologically confirmed, CanAg-positive (&ge;75% tumor cells with 2+/3+ staining) non-colorectal/pancreatic solid tumors that are inoperable/metastatic and refractory to standard therapy, excluding those with leptomeningeal or progressive brain disease. Key requirements include ECOG 0-2, adequate organ function (ANC &ge;1,500/mm <sup>3</sup>, platelets &ge;100,000/mm <sup>3</sup>, creatinine &le;1.5 mg/dL), no active infections, and &ge;4-week washout from prior therapies. Strict exclusion criteria address comorbidities, concurrent malignancies, and treatment-related restrictions to ensure patient safety.

Administration Dosage
Thirty patients were treated with huC242-DM4, receiving a single intravenous (IV) infusion once every three weeks. Cohorts of 3 patients initially were enrolled on each dose level. Patients have received huC242-DM4 at 18, 36, 60, 90, 126, 168, 223, and 297 mg/m2.

NCT Number NCT00352131  Clinical Status PHASE1
Clinical Description A Phase I Study to Assess the Safety and Pharmacokinetics of huC242-DM4 Administered as a Single Intravenous Infusion Once Every Three Weeks to Subjects With Solid Tumors
Primary Endpoint
The primary study objectives focus on assessing dose-limiting toxicities and determining the maximum tolerated dose of the investigational agent, with both measures being evaluated throughout the trial duration.
Other Endpoint
Secondary endpoints involve comprehensive evaluation of toxicity profiles, pharmacokinetic properties, and antitumor activity, all monitored continuously during the trial period to assess treatment safety and preliminary efficacy.
Experiment 2 Reporting the Activity Date of This ADC [2]
Patients Enrolled
ligibility requires histologically confirmed metastatic/locally advanced gastric/GEJ adenocarcinoma (AJCC IIIA-IV) with CanAg-positive expression, ECOG PS<1, one prior chemotherapy line failure, measurable disease per RECIST, and adequate organ function (ANC>1,500/mm <sup>3</sup>, platelets>100,000/mm <sup>3</sup>, creatinine&le;1.5xULN). Key exclusions include active infections, grade&ge;2 neuropathy, CNS metastases, recent malignancies (<2yrs disease-free except non-melanoma skin/cervical CIS/prostate cancer), concurrent anticancer therapies, and significant comorbidities (uncontrolled diabetes, recent MI, heart failure). Reproductive-age patients require negative pregnancy testing and contraception compliance.

Clinical Description A Phase II, Open Label, Multiple Center Study of huC242-DM4 Given as an Intravenous Infusion Once Every Three Weeks to Patients With Metastatic Gastric or Gastroesophageal Junction Carcinomas
Primary Endpoint
The primary endpoint of the study is assessment of objective response rate, with evaluation conducted annually throughout the trial period to determine treatment efficacy.
Other Endpoint
Secondary endpoints include duration of response, progression-free survival, safety/tolerability profile, pharmacokinetic analysis, and tumor FDG uptake effects-all monitored continuously during the study to characterize treatment durability, safety, pharmacologic properties, and metabolic impact.

Experiment 4 Reporting the Activity Date of This ADC [4]
Patients Enrolled
Metastatic or inoperable colorectal, pancreatic, and other CanAg-expressing tumors who have failed standard therapy (about 95% of pts. had received = 4 prior chemotherapy regimens).
Administration Dosage
A single intravenous (IV) infusion once every three weeks, 18, 36, 60, 90, 126, 168, 223, and 297 mg/m2.
