This study evaluates the safety and tolerability of the investigational drug EF-022 in the treatment of adult patients with Recurrent Respiratory Papillomatosis (RRP). Patients will be administered EF-022, either intramuscular or subcutaneous, for a period of 6 months. Preliminary effect of the drug on the disease will be evaluated by following the number and severity of the lesions in the respiratory tract and the effect on voice changes.
The etiology of RRP is associated with local immune suppression at disease-involved sites.
EF-022, a Vitamin D-Binding protein Macrophage Activating Factor, modulates the innate arm of the immune system to alleviate immune suppression. The investigators hypothesize that EF-022 may modulate the immune response in a manner that might slow down or even prevent disease progression.
Adult subjects will be treated weekly with EF-022 for a period of 6 months by either intramuscular or subcutaneous administration.
The primary objective of the study is to evaluate the safety and tolerability of EF-022 administered to adult subjects with recurrent respiratory papillomatosis either IM or SC.
The main response assessment will be performed over the 6 months period by:
- Evaluating lesion size and/or number of disease-involved sites by Coltera-Derkay score
- Assessment of degree of voice disorder using the VHI-10 score
- Symptomatic assessment of dyspnea/stridor
Allocation: Non-Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

The vitamin K-dependent cofactor of activated PROTEIN C. Together with protein C, it inhibits the action of factors VIIIa and Va. A deficiency in protein S; (PROTEIN S DEFICIENCY); can lead to recurrent venous and arterial thrombosis.
An autosomal dominant disorder showing decreased levels of plasma protein S antigen or activity, associated with venous thrombosis and pulmonary embolism. PROTEIN S is a vitamin K-dependent plasma protein that inhibits blood clotting by serving as a cofactor for activated PROTEIN C (also a vitamin K-dependent protein), and the clinical manifestations of its deficiency are virtually identical to those of protein C deficiency. Treatment with heparin for acute thrombotic processes is usually followed by maintenance administration of coumarin drugs for the prevention of recurrent thrombosis.

A protein that plays a fundamental role in the Vitamin D mediated transport of calcium in reptiles, amphibians, birds and mammals. It is found in the intestine, kidneys, egg shell gland, brain, and possibly other organs. Its molecular weight is species dependent.
A 67-kDa sialic acid binding lectin that is specific for MYELOID CELLS and MONOCYTE-MACROPHAGE PRECURSOR CELLS. This protein is the smallest siglec subtype and contains a single immunoglobulin C2-set domain. It may play a role in intracellular signaling via its interaction with SHP-1 PROTEIN-TYROSINE PHOSPHATASE and SHP-2 PROTEIN-TYROSINE PHOSPHATASE.
A heat-stable, low-molecular-weight activator protein found mainly in the brain and heart. The binding of calcium ions to this protein allows this protein to bind to cyclic nucleotide phosphodiesterases and to adenyl cyclase with subsequent activation. Thereby this protein modulates cyclic AMP and cyclic GMP levels.
