Oxemia (Desidustat) has received approval from the Drug Controller General of India. This was an incredible team effort by Zydans across the organization and I am so proud of what we have accomplished. Oxemia is a breakthrough treatment for Anemia associated with Chronic Kidney Disease in Patients either on Dialysis or Not on Dialysis, and will help improve quality of life for CKD patients. Team #zydus , on to our next effort!

Desidustat (INN, also known as ZYAN1) is a drug for the treatment of anemia of chronic kidney disease. This drug with the brand name Oxemia is discovered and developed by Zydus Life Sciences.[1] The subject expert committee of CDSCO has recommended the grant of permission for manufacturing and marketing of Desidustat 25 mg and 50 mg tablets in India,based on some conditions related to package insert, phase 4 protocols, prescription details, and GCP.[2] Clinical trials on desidustat have been done in India and Australia.[3] In a Phase 2, randomized, double-blind, 6-week, placebo-controlled, dose-ranging, safety and efficacy study, a mean hemoglobin increase of 1.57, 2.22, and 2.92 g/dL in desidustat 100, 150, and 200 mg arms, respectively, was observed.[4] The Phase 3 clinical trials were conducted at additional lower doses as of 2019.[5] Desidustat is developed for the treatment of anemia as an oral tablet, where currently injections of erythropoietin and its analogues are drugs of choice. Desidustat is a HIF prolyl-hydroxylase inhibitor. In preclinical studies, effects of desidustat was assessed in normal and nephrectomized rats, and in chemotherapy-induced anemia. Desidustat demonstrated hematinic potential by combined effects on endogenous erythropoietin release and efficient iron utilization.[6][7] Desidustat can also be useful in treatment of anemia of inflammation since it causes efficient erythropoiesis and hepcidin downregulation.[8] In January 2020, Zydus entered into licensing agreement with China Medical System (CMS) Holdings for development and commercialization of desidustat in Greater China. Under the license agreement, CMS will pay Zydus an initial upfront payment, regulatory milestones, sales milestones and royalties on net sales of the product. CMS will be responsible for development, registration and commercialization of desidustat in Greater China.[9] It has been observed that desidustat protects against acute and chronic kidney injury by reducing inflammatory cytokines like IL-6 and oxidative stress [10] A clinical trial to evaluate the efficacy and safety of desidustat tablet for the management of Covid-19 patients is ongoing in Mexico, wherein desidustat has shown to prevent acute respiratory distress syndrome (ARDS) by inhibiting IL-6.[11] Zydus has also received approval from the US FDA to initiate clinical trials of desidustat in chemotherapy Induced anemia (CIA).[12]. Desidustat has met the primary endpoints in the phase 3 clinical trials and Zydus had filed the New Drug Application (NDA) to DCGI in November, 2021.[13]\

Zydus receives DCGI approval for new drug Oxemia; what you need to know
The new drug is an oral, small molecule hypoxia-inducible factor-prolyl hydroxylase (HIF-PH) inhibitor, Zydus said in a statement.

Gujarat-based pharma company Zydus Lifesciences on Monday received the Drugs Controller General of India (DCGI) approval for its new drug application for a first-of-its-kind oral treatment for anemia associated with Chronic Kidney Disease (CKD) – Oxemia (Desidustat).
The new drug is an oral, small molecule hypoxia-inducible factor-prolyl hydroxylase (HIF-PH) inhibitor, the drug firm said in a statement.
Desidustat showed good safety profile, improved iron mobilization and LDL-C reduction in CKD patients in DREAM-D and DREAM-ND Phase III clinical trials, conducted in approximately 1,200 subjects. Desidustat provides CKD patients with an oral convenient therapeutic option for the treatment of anemia. The pharma major did not, however, declare the cost per dose if the drug is available in the market.
“After more than a decade of research and development into the science of HIF-PH inhibitors, results have demonstrated that Oxemia addresses this unmet need and additionally reduces hepcidin, inflammation and enables better iron mobilization. This advancement offers ease of convenience for the patient and will also reduce the disease burden by providing treatment at an affordable cost, thereby improving the quality of life for patients suffering from Chronic Kidney Disease,” Chairman of Zydus Lifesciences Pankaj Patel said.
Chronic Kidney Disease (CKD) is a progressive medical condition characterised by a gradual loss of kidney function and is accompanied by comorbidities like anemia, cardiovascular diseases (hypertension, heart failure and stroke), diabetes mellitus, eventually leading to kidney failure.
