Efficacy Study of [F-18]RGD-K5 Positron Emission Tomography (PET) as a Tool to Monitor Response to an Anti-angiogenic Drug

2014-08-27 03:18:53 | BioPortfolio

Summary

A Pilot Phase II Study

The primary objective for this study is:

- To explore the usefulness of [F-18]RGD-K5 PET/CT to predict efficacy or early response to Avastin® (the anti-angiogenesis drug) plus chemotherapy treatment before the full course of treatment is completed

The secondary objectives for this study are:

- To continue safety evaluation by collection of safety data from all patients

- To gain experience with [F-18]RGD-K5 PET/CT in order to improve the study design and conduct of future studies

Design: An open label, non-randomized, uncontrolled, single group assignment, pilot efficacy study

Duration: Screening visit (3-4 hrs), pre-treatment imaging visit of [F-18]RGD-K5 PET/CT (~ 3-4 hrs) and the standard [F-18]FDG PET/CT (~ 3-4 hrs) or diagnostic CT, followed by two [F-18]RGD-K5 PET/CT scans, one after the second but before the third Avastin® treatment, and one after the fourth but before the fifth Avastin® treatment, and a follow up standard [F-18]FDG PET (~ 3-4 hrs) or diagnostic CT.

Procedures: Informed consent, collection of demographic information, medical history, blood labs, physical examination, vital signs, ECGs, three sets of [F-18]RGD-K5 dosing and imaging scans including pretreatment, early mid-treatment, and later mid-treatment, concomitant medication collection, adverse event monitoring, and assessment of tumor response to treatment

Patients: Approximately forty (40) patients with non-squamous non-small cell lung cancer, metastatic breast cancer, metastatic colon or rectum cancer who will receive chemotherapy plus Avastin®. This allows for approximately 30 evaluable patients to complete this study at approximately four to eight sites internationally

Description

The aim of this pilot study is to examine the utility of a new molecular imaging tracer, [F-18]RGD-K5 to monitor treatment responses in patients scheduled to undergo treatment with Avastin® (Bevacizumab) plus standard chemotherapy. The changes of [F-18]RGD-K5 PET/CT image scans between before treatment and after both mid-treatment cycles of Avastin® (Bevacizumab) will be evaluated. The hypothesis for this study is that changes in the uptake of [F-18]RGD-K5 PET in tumors may reflect changes in the level of integrin expression and/or angiogenesis. This pilot study will help to define if changes in uptake of [F-18]RGD-K5 are an early indicator of treatment efficacy to Avastin®.

A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
