简要总结
Iron deficiency anaemia (Haemoglobin, Hb < 12gm/dl) is one of India's major public health problems particularly in women. Effective control of iron deficiency anaemia decreases the incidence of fatigue, bodyache, headache, lack of concentration and menstrual complications. Iron bisglycine chelate has been used successfully to treat iron deficiency anaemia and is also a well tolerated therapy. Use of ferrous bisglycinate chelate one tablet daily as a nutritional supplement is well established in India. For treatment of iron deficiency anaemia, some women may need 1 tablet/day, while some may need 2 tablets/day. In India, ferrous ascorbate, 1 tablet daily is a widely accepted form of treatment for iron deficiency anaemia. The primary purpose of this study is to demonstrate the efficacy and tolerability profile of ferrous bisglycinate chelate to support the registration of this product as a 'drug' in India. Comparative data between ferrous bisglycinate chelate and ferrous ascorbate will also augment our existing knowledge, which will further support appropriate use of ferrous bisglycinate chelate for the treatment of iron deficiency anaemia. Study design and patient population: This will be a multicentre, randomized, laboratory-blinded, parallel- group study. It is projected that the study will randomize 270 women (90 subjects in each treatment arm) with iron deficiency anaemia (Hb 6-9 gm/dl + serum Ferritin <15 μg/l) to either ferrous bisglycinate chelate 1 or 2 tablets/day, or ferrous ascorbate 1 tablet/day for 8 weeks. At fortnightly visits, blood will be collected for Hb (to evaluate efficacy), adverse events will be documented (to evaluate tolerability), the investigational drugs will be dispensed and reasons for non compliance will be recorded. Study endpoints: The primary endpoint is defined as the rise of Hb from baseline after 8 weeks of treatment in each ferrous bisglycinate chelate group (1 tablet/day and 2 tablets/day). The secondary endpoints include the difference in the average change in Hb, difference in the rate of rise of Hb, difference in the proportion of patients who achieve a target Hb ≥12gm/dl and difference in the % incidence of gastrointestinal side effects during 8 week therapy with 2 dosing regimens of ferrous bisglycinate chelate (1 tablet/day and 2 tablets/day) and ferrous ascorbate 1 tablet/day.
详细描述
Rationale Iron deficiency is the most common form of malnutrition globally. In India, nearly 70% of women are estimated to be iron deficient. Iron deficiency anemia (IDA, Hb <12gm/dl) is a very late manifestation of iron deficiency. IDA is a consequence of decreased iron intake, increased iron loss from the body or increased iron requirements Blood loss during menstruation can predispose women to have poor iron stores and the presence of excess menstrual bleeding can contribute to the development of IDA in women. Patients with IDA usually present with fatigue, headache, bodyache, paraesthesia and lack of concentration. IDA can cause menorrhagia, which in turn can aggravate IDA. With severe anemia, there may be amenorrhoea as well.
Iron deficiency anaemia is often treated with iron tablets such as ferrous sulphate, ferrous fumarate and ferrous gluconate. It usually takes about 6-10 weeks for Hb to return to normal after initiation of oral iron therapy. Although efficacious from a haematological point of view, most of these therapies are associated with limiting gastrointestinal side effects (e.g. nausea, vomiting, constipation, diarrhoea and abdominal pain), which eventually reduce patient compliance.
Among the recent alternatives, iron bisglycine chelate has been used successfully to treat iron deficiency anaemia and is also a well tolerated therapy.
Use of ferrous bisglycinate chelate (each tablet contains 60mg of elemental iron as ferrous bisglycinate chelate, 1 mg folic acid, 5 mcg cyanocobalamin and 15 mg zinc bis-glycinate), 1 tablet daily is well established as a nutritional supplement in India. However, for treatment of iron deficiency anaemia, some women may need 1 tablet/day, while some may need 2 tablets /day.
In India, ferrous ascorbate tablets (each tablet contains 100 mg elemental iron as ferrous ascorbate, with 1 mg folic acid) in the recommended dose of 1 tablet daily are a widely accepted form of treatment for iron deficiency anaemia.

结局指标
主要结局
Change From Baseline in Hemoglobin (Hb) After 8 Weeks of Treatment in Each Ferrous Bisglycinate Chelate Group (1 Tablet Daily and 2 Tablets Daily)
时间窗: Baseline and Week 8
At fortnightly visits, blood was collected for Hb. Baseline (Visit 0) was not more than 5 days from Week 1 or randomization. Change from Baseline was calculated by subtracting Baseline values from post-Baseline values.
次要结局
- Mean Change in Hb From Baseline to 8 Weeks(Baseline to Week 8)
- Percentage of Participants Who Achieved a Target Hb More Than or Equal to 12 gm/dL After 8 Weeks of Treatment(Up to Week 8)
- Difference in Percentage of Participants With Gastrointestinal Side Effects During 8 Weeks Treatment With Ferrous Bisglycinate Chelate and Ferrous Ascorbate(Up to Week 8)
- Mean Change in Hb During 8 Weeks Therapy(Up to Week 8)
