Overview
Brief Summary
This is a randomized, double blind, placebo controlled, multicentre, phase 3 clinical trial to evaluate the efficacy and safety of Desidustat oral tablets for treatment of chemotherapy induced anemia in patients with solid tumor malignancy. The study consists of screening period of up to 4 weeks, treatment period of 12 weeks, and end of the study visit at Week 14. The total duration of the study will be 126 days including screening period of 28 days.
Informed consent will be obtained from all eligible participants before any study related activity according to the applicable regulatory requirements. After signing the informed consent form, participants will be screened for eligibility to participate in the study based on clinical history, physical examination, vital signs, ECG, and laboratory parameters (hematology, biochemistry, urine analysis, Serum Hepcidin, VEGF, Vitamin B12 and Folic acid, serum beta-HCG, iron profile, and virology tests for HIV type 1 and type 2, HBsAg and Anti-HCV antibody). Eligibility criteria will be assessed at screening (Visit 1) and verified at randomization visit (Visit 2).
Eligible participants will be randomly assigned to either test arm (Desidustat) or comparator arm (matching placebo) with an allocation ratio of 2 and 1. Study drug (test or placebo) will be administered three times a week for a period of 12 weeks with a goal to achieve hemoglobin level within the target of 11 g/dL.
Assessment of hemoglobin level for dose interruption will be done at the site by calibrated HemoCue instrument.
During the study period, dose review and interruption will be permitted every 3 weeks, from visit-3 (Day 21). Dose interruption will be based on hemoglobin level as assessed by change in hemoglobin level compared to previous visit.
If at any visit hemoglobin level is greater than or equals to 12 gm/dl, Desidustat treatment will be interrupted for 21 days, after which hemoglobin assessment would be done with Hemocue, and if the hemoglobin level falls below 11 gm/dl, Desidustat treatment would be re-initiated. if not therapy would be interrupted till next scheduled visit.
During the study, participants will be followed up at the study sites for 7 scheduled visits.
At screening visit (Visit 1 - Day - 28)
Randomization visit (Visit 2 - Day 0)
Follow-up visits during the treatment period
Visit 3 (Day 21 plus or minus 3 days), Visit 4 (Day 42 plus or minus 3 days), Visit 5 (Day 63 plus or minus 3 days), Visit 6 (Day 84 plus or minus 3 days)
Safety follow-up (Visit 7, Day 98 plus or minus 3 days) will be conducted after 2 weeks (within allowable window period) of EOT period.
During the follow-up visits, participants will be evaluated for efficacy and safety.
Evaluation of efficacy will be done by assessing mean change in hemoglobin level from baseline to Week 12 in Desidustat arm compared to placebo arm.
Additional efficacy assessment will be done by assessing mean of maximum increase in hemoglobin level in Desidustat arm from baseline to Week 12 without rescue therapy in comparison to placebo arm.
Efficacy will be assessed by proportion of participants achieving Hemoglobin response and requiring rescue therapy.
Median time to achieve target hemoglobin level ( greater than or equals to 11 g/dL) and mean change from baseline to Week 12 in serum hepcidin level, serum VEGF level will also be evaluated.
To evaluate the safety, participants will be assessed by physical examination, vital signs, ECG, and safety laboratory parameters as described in the schedule of assessments.
All the participants will be evaluated for adverse events throughout the study period. If further investigations are required in case of any AE, investigator is advised to assess the AE and take necessary action. Participants are advised to contact the investigator for any discomfort.
To ensure the safety of the trial participants, an oversight on interim safety data was provided by the independent data and safety monitoring board (DSMB ). Interim safety data of first 24 participants up to 21 days after randomization was presented to the independent DSMB in blinded manner. Unanimous decision of continuation of the trial was provided by DSMB members on 24th December 2025.
