Zydus Lifesciences announced the publication of two manuscripts detailing the DREAM-ND and DREAM-D Phase 3 study results of Desidustat, a novel HIF-PH inhibitor in the prestigious American Journal of Nephrology.
Desidustat’s development is based on the Nobel Prize in Medicine winning science on discoveries of the oxygen sensing mechanism of cells through hypoxia-inducible factor (HIF). Desidustat works by stabilizing the HIF complex and stimulating endogenous erythropoietin production in Chronic kidney disease (CKD) patients thereby improving haemoglobin levels and treating anemia. CKD patients irrespective of their dialysis status have been reported to develop anemia leading to significant morbidity, mortality, progression of kidney disease and higher blood transfusion rates. Chronic Kidney Disease patients are often on 8-13 different medications and are at safety risks of drug-drug interactions.
“We are pleased as the results of our DREAM-ND and DREAM-D trials are published in the American Journal of Nephrology”, said Mr. Pankaj R. Patel, Chairman, Zydus Lifesciences Ltd. “In our quest to develop a potential best-in-class HIF-PH inhibitor, our research team had envisaged to develop a candidate which achieves primary and secondary end-points, requires less frequent dosing and has a reduced potential for drug-drug interactions. The results published in American Journal of Nephrology demonstrates that Desidustat met all the primary and secondary end-points with thrice a week oral dosing regimen, was well-tolerated and also ensured a durable treatment effect in both non-dialysis and dialysis dependent Chronic Kidney Disease patients with anemia.”
In the DREAM-ND trial, Desidustat oral dose was administered thrice a week compared to Darbepoetin subcutaneous injection in 588 Chronic Kidney Disease patients not-on-dialysis (randomized 1:1). In the Desidustat group the mean baseline Hemoglobin level was 8.97 g/dL which improved to 10.90 g/dL in Weeks 16–24, and in the Darpepoetin group the mean baseline haemoglobin levels was 8.92 g/dL which improved to 10.77 g/dL, which met prespecified non-inferiority of Desidustat to Darbepoetin as per protocol. The hemoglobin responders were significantly higher in the Desidustat group compared to the Darbepoetin group. There was a statistically significant reduction in hepcidin and LDL-c in the Desidustat arm as compared to the injectable Darbepoetin arm. The safety profile of the Desidustat oral tablet was comparable with the Darbepoetin alfa injection in CKD patients not on dialysis.
In the DREAM-D trial, Desidustat oral tablets were administered thrice a week compared to Epoetin alfa subcutaneous injection in 392 Chronic Kidney Disease patients on dialysis (randomized 1:1). In the Desidustat group the mean baseline hemoglobin level was 9.57 g/dL which improved to 10.47 g/dL in weeks 16–24 and in the Epoetin group the mean baseline haemoglobin level was 9.46 g/dL which improved to 10.32 g/dL, which met prespecified non-inferiority of Desidustat to Epoetin as per protocol. The number of haemoglobin responders were significantly higher in the Desidustat group as compared to the Epoetin alfa group. There was a statistically significant reduction in hepcidin and LDL-c in the Desidustat arm as compared to the injectable Epoetin alfa arm. The safety profile of the Desidustat oral tablet was comparable with the epoetin alfa injection in CKD patients on dialysis.
Desidustat is currently approved only in India as OxemiaTM for patients with CKD induced anemia. It is currently undergoing Phase III clinical development in China for anemia in Chronic Kidney Disease Patients. Desidustat is under Phase I(b) clinical evaluation under a IND with the United States Food and Drug Administration (USFDA) for Chemotherapy Induced Anemia (CIA) in cancer patients.
Previously, results of multiple other studies on Desidustat have been published in international peer-reviewed scientific journals of repute such as European Journal of Pharmacology, Journal of Medicinal Chemistry, Drug Development Research, Drug Research (Stuttg), Xenobiotica, American Journal of Nephrology and Clinical Pharmacokinetics.
