Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to learn more about how a new study agent works inside the body. This study agent is a protein called 68Ga-F(ab')2-trastuzumab fragments (HERScan). This is a radioactive tracer that was developed at MSKCC to target the HER2 protein on cancer cells. By giving this tracer to patients whose cancers have the HER2 protein, we hope to be able to see the level of HER2 on the cancer cells using PET scanning.

Study Groups

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

1

Patients with invasive solid tumors

Group Type ACTIVE_COMPARATOR

PET Imaging with Ga-68 Labeled F(ab') 2- Trastuzumab

Intervention Type RADIATION

Pt will undergo one PET study following the i.v. administration of 10mCi of 68Ga-F(ab')2-trastuzumab fragments (HERScan). The PET study will be performed within 4 weeks of the patient's most recent imaging studies. A subset of 10 patients who have evidence of tumor uptake and localization with the 68Ga-F(ab')2-trastuzumab fragments will be asked to undergo follow-up PET scans (up to a maximum of 3) to examine the time course of HER-2 expression. These follow-up PET scans will be performed concurrently with the patient's standard imaging studies to evaluate response to their current therapy as per their treating physicians.

2

Patients with advanced solid tumors that express HER2 with tumors that are HER2 1+ by IHC or FISH.

Group Type ACTIVE_COMPARATOR

PET Imaging with Ga-68 Labeled F(ab') 2- Trastuzumab

Intervention Type RADIATION

Once safety and feasibility has been established in this group, then enrollment to the HER2 1+ cohort will commence. Pt will undergo one PET study following the i.v. administration of 10mCi of 68Ga-F(ab')2-trastuzumab fragments (HERScan). The PET study will be performed within 4 weeks of the patient's most recent imaging studies. A subset of 10 patients who have evidence of tumor uptake and localization with the 68Ga-F(ab')2-trastuzumab fragments will be asked to undergo follow-up PET scans (up to a maximum of 3) to examine the time course of HER-2 expression. These follow-up PET scans will be performed concurrently with the patient's standard imaging studies to evaluate response to their current therapy as per their treating physicians.

Patients will also have blood samples drawn prior to infusion and if possible, approximately at 5, 10, 30, 60 minutes and 3-6 hours after 68Ga-DOTA-trastuzumab F(ab')2 infusion. To assess for in-vivo stability of the radiopharmaceutical if possible, HPLC will be performed.
