Background summary
Background of the study:
The prognosis of Pulmonary arterial hypertension (PAH) associated with scleroderma continues to be poor with a 3-year survival of 56%, despite implementation of new therapies. Therefore, new therapeutic strategies are warranted. One such strategy could be pharmacological inhibition of the epidermal growth factor receptor (EGFR), as recent research shows that the EGFR plays an important role in the pathogenesis of both PAH and scleroderma. The chimeric monoclonal antibody Cetuximab (ErbituxĂ’) against the extracellular domain of the EGFR is registered for the treatment of colorectal cancer and SCCHN. In this study, we evaluate the use of Cetuximab in the treatment of scleroderma associated PAH.
Objective of the study:
The first objective is to evaluate the safety of cetuximab in patients with scleroderma associated PAH. The secondary objective is to assess efficacy.
Study design:
This will be a phase II study, open-labelled, in one hospital in the Netherlands. The first phase consists of the successive enrollment of three patients. After evaluation, enrollment will be enhanced to a total number of 20 patients.
Study population:
> 18-year-old patients with scleroderma-associated PAH
Intervention (if applicable):
Cetuximab, loading dose 400 mg/m2 week 1. week 2 t/m week 11 maintainance dose of 250 mg/m2.
Primary study parameters/outcome of the study:
To describe the safety of cetuximab in scleroderma associated PAH.
Secundary study parameters/outcome of the study (if applicable):
To explore the efficacy of cetuximab in terms of: stroke volume, 6 minute walk test, changes on HRCT, changes in nailfold microcirculation, changes in molecular parameters (NT-proBNP)
Nature and extent of the burden and risks associated with participation, benefit and group relatedness (if applicable):
Number of institutional visits: 15. Number of physical examinations 15. Number of blood samples: 15. Other invasive investigations: Right heart catheterization 1x; skin biopsy 2x.
Risks associated with investigations: risks associated with right heart catheterization (1:2000 major complications) and skin biopsies. Major risks associated with investigational product: 5% allergic side effects; severe infusion reactions 3% of subjects, fatal outcome < 1 in 1000; 5% conjunctivitis; 80% skin toxicity of which 15% severe (CTCAE Grade 3); 25 out of 100 patients report dyspnoea.
SSc-PAH is a severe disease with a poor prognosis, but this intervention methods may provide advantages over existing therapy in terms of efficacy and treatment burden compared with existing therapy.
Study objective
As EGFR plays a role in pathogenesis of both pulmonary arterial hypertension and systemic sclerosis, EGFR inhibition will lead to beneficial effects in disease course.
Intervention
All participants will receive cetuximab at a loading dose of 400 mg/m2 in week 1, followed by a weekly dose of 250 mg/m2 starting from week 2, up to a total of 12 weeks.
