PREVAX: A Phase I Clinical Trial of an EGF-Based Vaccine in Moderate-to-Severe COPD Patients.

Background: EGFR has been suggested to contribute to COPD development and progression. Excessive ligand activation of the receptor leads to epithelial hyperproliferation and increased production of mucus, together with alterations in the primary cilia. The present study was designed to evaluate the safety and effect of depleting EGF in moderate-to-severe COPD patients, with an EGF-based vaccine.

Racotumomab in Non-Small Cell Lung Cancer as Maintenance and Second-Line Treatment.

Introduction: Racotumomab is a therapeutic vaccine based on a monoclonal anti-idiotypic antibody developed by the Molecular Immunology Center in Havana, Cuba, that is registered in Cuba and Argentina for treatment of non-small cell lung cancer. It induces a specific humoral and cellular immune response against the N-glycolyl GM3 (NeuGcGM3) ganglioside present in tumor cells, thereby provoking the death of these cells.

Objective: Evaluate racotumomab vaccine use as switch maintenance and second-line therapy for patients with inoperable non-small cell lung cancer in routine clinical practice, outside the framework of clinical studies, and assess the overall survival, stage-specific survival and safety in these patients.

CIMAvax EGF (EGF-P64K) vaccine for the treatment of non-small-cell lung cancer.

Epidermal growth factor receptor (EGFR) is overexpressed in many epithelial tumors and its role in the development of non-small-cell lung cancer (NSCLC) is widely documented. CIMAvax-EGF is a therapeutic cancer vaccine composed by recombinant EGF conjugated to a carrier protein and emulsified in Montanide ISA51. Vaccination induces antibodies against self-EGF that block EGF-EGFR interaction and inhibit EGFR phosphorylation.

Effect of blockade of the EGF system on wound healing in patients vaccinated with CIMAvax® EGF.

Background: The epidermal growth factor receptor (EGFR) signaling system is frequently unbalanced in human malignancies due to increased ligand production, receptor overexpression, receptor mutations, and/or cross-talk with other receptor systems. For this reason, the EGFR is an attractive target for anticancer therapy. The epidermal growth factor also plays an important role in regulating multiple facets of cutaneous wound healing, including inflammation, wound contraction, proliferation, migration, and angiogenesis.

Nimotuzumab plus radiotherapy for unresectable squamous-cell carcinoma of the head and neck.

The prognosis of patients with advanced head and neck cancer remain dismal. For this tumor type, elevated levels of EGFR are associated with a shorter disease free survival and time to treatment failure, reflecting a more aggressive phenotype. Nimotuzumab is a humanized monoclonal antibody that recognizes domain III of the extracellular region of the EGFR, within an area that overlaps with both the surface patch recognized by cetuximab and the binding site for EGF.

Phase II randomized controlled trial of an epidermal growth factor vaccine in advanced non-small-cell lung cancer.

Purpose: We show the result of a randomized phase II clinical trial with an epidermal growth factor (EGF)-based cancer vaccine in advanced non-small-cell lung cancer (NSCLC) patients, evaluating immunogenicity, safety, and effect on survival.

Patients And Methods: Eighty patients with stage IIIB/IV NSCLC after finishing first-line chemotherapy were randomly assigned to receive best supportive care or EGF vaccinations.

Results: Vaccination was safe.

Treatment of NSCLC patients with an EGF-based cancer vaccine: report of a Phase I trial.

Epidermal Growth Factor (EGF) promotes tumor cell proliferation and survival upon binding to its receptor. We have developed a new active specific immunotherapy based on EGF deprivation. In the present paper, we show the results of a Phase I trial in 43 patients with advanced non-small cell lung cancer (NSCLC) who received the EGF vaccine.
