WebGivosiran’s Phase III trial did not include an arm for patients that received hemin prophylaxis and no studies directly compare givosiran and hemin prophylaxis. Therefore, in the absence of comparative evidence, the efficacy of givosiran versus hemin prophylaxis in reducing acute attacks was assumed to be equivalent. A lyophilised form of hemin is used as a pharmacological agent in certain cases for the treatment of porphyria attacks, particularly in acute intermittent porphyria. Administration of hemin can reduce heme deficits in such patients, thereby suppressing the activity of delta-amino-levulinic acid synthase (a key enzyme in the synthesis of the porphyrins) by biochemical feedback, which in turn reduces the production of porphyrins and of the toxic precursors of heme. In such pharmacologi… the highway band kc https://ecolindo.net
