sEphB4-HSA with CRT

Arm Description

sEphB4-HSA: Loading dose at fixed dose of 10mg/Kg per below schema on D1 Concurrent dose per below schema D15-43 and given on an every other week basis Concurrent chemotherapy drug (either cisplatin or carboplatin): Per treating physician discretion, and treatment plan is based per NCCN guidelines. These can be administered in tri-weekly or weekly doses during the radiation period. The participant will receive the first infusion on Day 15 (+/- 3 days). Cetuximab: Loading dose 400 mg/m2 on D9 Concurrent dose 250mg/m2 weekly D15± 3 day window RT: 6930 cGy IMRT starting D15-D18

Outcomes

Primary Outcome Measures

The primary endpoint is whether a dose-limiting toxicity (DLT) occurs

Severe cetuximab-associated rash is defined as per Lacouture 2010 criteria69, namely > 20 papules or pustules OR > 5 areas of erythema or edema < 1 cm (this is grade 3A) or > 20 papules/pustules OR > 5 areas of erythema or edema < 1 cm AND pain, pruritus, or effect on emotions or functioning (this is a commonly used criteria for grading of rash specifically related to EGFR inhibitors, such as cetuximab).

Secondary Outcome Measures

To assess the effect of adding sEphB4-HSA to radiation and cetuximab in newly-diagnosed EGFR-expressing LAHNSCC and heavy smoking histories on Locoregional disease

Tumor response will be assessed in participants with measurable disease at start of therapy by measuring change in size (and/or FDG avidity) on CT (and/or PET/CT). LRC will be calculated as the time from completion of locoregional therapy until disease recurrence at the primary site or in the neck.

To assess the effect of adding sEphB4-HSA to radiation and cetuximab in newly-diagnosed EGFR-expressing LAHNSCC and heavy smoking histories on Distant Control

DC will be calculated as the time from completion of locoregional therapy until disease recurrence at a site other than the primary site or neck.

To assess the effect of adding sEphB4-HSA to radiation and cetuximab in newly-diagnosed EGFR-expressing LAHNSCC and heavy smoking histories on Disease Free Survival

DFS will be calculated as the time from completion of locoregional therapy until either disease recurrence at any site or until death.

Overall Survival

OS will be calculated as the time from diagnosis of LAHNSCC to death

5. Study Description

Brief Summary

This is a Phase I dose-escalation study of sEphB4-HSA in combination with chemotherapy, cetuximab and radiotherapy (RT). The purpose is to estimate the maximum tolerated dose (MTD) that can be administered concurrently with Cetuximab and radiation in patients with locally advanced, Stage III or IV A-B squamous cell carcinomas of the head or neck with a history of at least ten pack-years of smoking.

Detailed Description

RT combined with the EGFR-targeted agent cetuximab represents a valuable alternative to platinum-based CRT and is FDA-approved for initial treatment of LAHNSCC, but outcomes remain unfavorable. Recently, EphB4 has emerged as another rational target. While minimally expressed in normal tissue, it is highly expressed in LAHNSCC and has been implicated in resistance to both EGFR-targeted therapy and to RT. Suppression of EphB4 in the preclinical setting has enhanced tumor death and enhanced radiosensitivity. The novel agent sEphB4-HSA is a fusion protein that binds the ligand for EphB4 and leads to inhibition of tumor proliferation and angiogenesis. It was well-tolerated as monotherapy in a phase I trial but has yet to be explored in combination with radiotherapy or EGFR-directed treatments. A combined modality approach adding sEphB4-HSA to standard-of-care RT plus cetuximab represents a rational, targeted approach for investigation in patients with high risk LAHNSS p16-negative or any patient with heavy smoking histories. Moreover, a short window period of sEphB4-HSA monotherapy between baseline biopsy and repeat biopsy prior to initiation of cetuximab with RT will both minimize potential treatment delay and allow for the identification of potential biomarkers of response to sEphB4-HSA. Finally, a third optional biopsy, to be done if feasible after initiation of cetuximab-radiation, will allow us to identify radiosensitization markers and potential markers for treatment de-escalation.
