A first-in-class, first-in-human, phase I trial of CIGB-552, a synthetic peptide targeting COMMD1 to inhibit the oncogenic activity of NF-κB in patients with advanced solid tumors.

CIGB-552 is a synthetic peptide that interacts with COMMD1 and upregulates its protein levels. The objectives of this phase I study were safety, pharmacokinetic profile, evaluation of the lymphocytes CD4+ and CD8+ and preliminary activity in patients with advanced tumors. A 3 + 3 dose-escalation design with seven dose levels was implemented.

Efficacy and safety of iorEPOCIM for chemotherapy- or radiotherapy-induced anemia in pediatric cancer patients.

Introduction: Recombinant human erythropoietin (RHuEPO) is an erythropoiesis stimulating agent (ESA) used to treat anemia in patients with total or relative erythropoietin deficit. In cancer patients, it is administered to optimize hemoglobin (Hb) levels, correct anemia and reduce the need for transfusions. Cuba produces a RHuEPO, registered in 1998 as iorEPOCIM, that is widely used in the national public health system, mainly to treat patients with anemia due to chronic kidney disease (CKD).
