Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to establish the safety profile and maximum tolerated dose (MTD) of the anti-PDGFRα monoclonal antibody IMC-3G3 in patients with advanced solid tumors who no longer respond to standard therapy or for whom no standard therapy is available.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

IMC-3G3

All patients will receive intravenous infusions of IMC-3G3, with the dose depending on which cohort they are enrolled into.

Group Type EXPERIMENTAL

IMC-3G3

Intervention Type BIOLOGICAL

Intravenously, once every week for Cohorts 1 through 3 and once every other week for Cohorts 4 and 5. Starting dose will be 4mg/kg in Cohort 1, with dose doubling between cohorts. Dose escalation of 100% (2 x previous dose) Dose escalation increment reduced to 33% (1.33 x previous dose). Cohorts 4 and 5 will receive 15mg/kg and 20mg/kg, intravenously, once every other week.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Histopathological-documented, measurable, or non measurable, advanced primary tumor or recurrent solid tumor or lymphoma unresponsive to standard therapy or for which there is no standard therapy available.
2. Eastern Cooperative Oncology Group (ECOG) performance status score of ≤ 2 at study entry.
3. Able to provide written informed consent.
4. Age 18 years or older.
5. Life expectancy of \> 3 months.
6. Adequate hematologic function, as defined by: an absolute neutrophil count ≥ 1500/mm3; a platelet count ≥ 100,000/mm3
7. Adequate hepatic function, as defined by: a total bilirubin level ≤ 1.5 x the upper limit of normal (ULN); aspartate transaminase (AST) and alanine transaminase (ALT) levels ≤ 2.5 x the ULN or ≤ 5 x the ULN if known liver metastases
8. Adequate renal function, as defined by serum creatinine level ≤ 1.5 x the ULN.
9. Uses effective contraception (per the institutional standard), if procreative potential exists.
10. Adequate recovery from recent surgery, chemotherapy, and radiation therapy.
11. Accessible for treatment and follow-up, must be treated at the participating center.

Exclusion Criteria
