Published Studies Related to Leena (Norethindrone / Ethinyl Estradiol)

Efficacy, cycle control, and safety of two triphasic oral contraceptives: Cyclessa (desogestrel/ethinyl estradiol) and ortho-Novum 7/7/7 (norethindrone/ethinyl estradiol): a randomized clinical trial. [2000.05]
The contraceptive efficacy, cycle control, and safety of a new low-dose, triphasic desogestrel/ethinyl estradiol oral contraceptive (CTR 77, Cyclessa(TM)) was compared to that of a marketed, triphasic norethindrone/ethinyl estradiol oral contraceptive (Ortho-Novum(R) 7/7/7).Cyclessa provides significantly improved cycle control with no weight gain.

Cycle control with oral contraceptives containing 20 micrograms of ethinyl estradiol. A multicenter, randomized comparison of levonorgestrel/ethinyl estradiol (100 micrograms/20 micrograms) and norethindrone/ethinyl estradiol (1000 micrograms/20 micrograms). [1999.03]
A randomized, open-label, multicenter study was undertaken to compare the effects of oral contraceptives (OC) containing 100 micrograms levonorgestrel (LNG)/20 micrograms ethinyl estradiol (EE) (Aless/Loette) and 1000 micrograms norethindrone acetate (NETA)/20 micrograms EE (Loestrin Fe 1/20) on menstrual cycle control over four cycles of use...

Multicenter randomized comparative trial of two low-dose triphasic combined oral contraceptives containing desogestrel or norethindrone. [1994.05]
OBJECTIVE: To compare a new triphasic oral contraceptive (OC) containing desogestrel and ethinyl estradiol (DSG/EE) with triphasic norethindrone/ethinyl estradiol (NE/EE) regarding effects on clinical efficacy, cycle control, and safety indices... CONCLUSION: Triphasic DSG/EE is an effective and safe OC with excellent acceptability and cycle control superior to that of triphasic NE/EE.

Pharmacokinetics of three bioequivalent norethindrone/mestranol-50 micrograms and three norethindrone/ethinyl estradiol-35 micrograms OC formulations: are "low-dose" pills really lower? [1989.09]
We have examined the pharmacokinetic parameters derived from the analysis of plasma ethinyl estradiol (EE) and norethindrone levels after administration of a single dose of three bioequivalent norethindrone-1mg/mestranol (ME)-50 micrograms formulations (Ortho-NovumR 1/50, NorinylR 1/50 and Norcept-MR 1/50) and three norethindrone-1mg/ethinyl estradiol-35 micrograms formulations (Ortho-Novum 1/35R, NorinylR 1/35, Norcept-ER 1/35) in a randomized crossover design involving 24 women for the 35 micrograms and 27 women for the 50 micrograms agents...

Bleeding patterns of women using Lunelle monthly contraceptive injections (medroxyprogesterone acetate and estradiol cypionate injectable suspension) compared with those of women using Ortho-Novum 7/7/7 (norethindrone/ethinyl estradiol triphasic) or other oral contraceptives. [2000.12]
Persistent and/or unpredictable bleeding is a common reason for discontinuation of hormonal contraceptive methods. An open-label, nonrandomized, parallel, controlled study compared the efficacy, safety, and cycle control of the new, highly efficacious monthly injectable contraceptive containing 25 mg medroxyprogesterone acetate (MPA) and 5 mg estradiol cypionate (E(2)C) (MPA/E(2)C) (Lunelle Monthly Contraceptive Injection) with that of the frequently used norethindrone 0.5, 0.75, 1.0 mg/0.035 mg ethinyl estradiol (NET/EE) triphasic oral contraceptive (Ortho-Novum 7/7/7)...

Study of Hsp90 Inhibitor, STA-9090 for Relapsed or Refractory Small Cell Lung Cancer [Active, not recruiting]
STA-9090 blocks Heat Shock Protein-09 (Hsp90), which is thought to be involved in regulating apoptosis or cell death in small cell lung cancer. In this research study, the investigators will look to see if STA-9090 has a therapeutic effect on small cell lung cancer. The investigators will also study the safety of STA-9090 and whether measuring circulating tumor cells may help in assessing response to treatment.

Effect of Consuming Food Cooked in Iron Utensils on Iron Status in Children With Iron Deficiency Anemia (IDA) [Completed]
Iron deficiency is a common problem in the world and more so in the developing countries with a prevalence of 64 % (using WHO cut-off values of Hb <11. 0 g/dl) among children, 9-36 months of age. The Pediatric population is especially vulnerable to iron deficiency anemia due to low intake of iron rich foods, rapid growth with high demand and losses of iron from body especially with the commonly found worm infestations in children. Mild to moderate iron deficiency is widely prevalent in children and can have several implications including failure to thrive, poor scholastic performance, repeated infections etc. Dietary measures along with therapeutic measures are recommended to combat Iron Deficiency Anemia (IDA). However, iron rich foods alone cannot be relied upon as a sole step to counter IDA. The utensil in which the food is cooked plays a major role in determining the final iron content of food. Several studies have documented that most of the foods (90%) contained significantly more iron when cooked in iron utensils depending on the acidity, moisture content, and cooking time of food. The daily dietary intake could vary from 11 to 6 mg of iron if iron utensil was used for cooking [3]. Food cooked in Aluminum (Al) utensils has a higher Al content which can be detrimental to healthy individuals and particularly to patients with chronic renal failure. In healthy persons, diseases of central nervous system, as well as of hematopoeitic system, skeletal system and respiratory system are described due to excess of Aluminium consumption. Aluminium utensils have fast replaced iron cooking pots from Indian kitchens, hence a study to know the effectiveness of iron cooking pot as a measure to combat IDA is necessary. Studies have shown the utility of cooking food in iron utensil in prevention of IDA but the investigators did not come across a study to document the use of this modality in treatment of IDA in children. Since the investigators anticipate that the improvement of iron status will be a gradual process, so the investigators decided to evaluate the utility of cooking food in iron utensils on iron status in children with non-severe IDA (Hb% < cutoff point for age but > 5 gm %. To test the following hypothesis "use of iron utensils for cooking food will result in improvement in iron status in Pediatric patients with nonsevere Iron Deficiency Anemia."
