| NCT00358462 ↗ | Mycoplasma Genitalium Antibiotic Susceptibility and Treatment (MEGA) | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 3 | 2007-01-01 | The purpose of this study is to find out which of 2 different antibiotics, doxycycline or azithromycin, works best against germs that may cause nongonococcal urethritis. Study participants will include approximately 1200 men, 16 years of age or older, attending a sexually transmitted diseases clinic in Seattle, Washington with clinical signs of urethral inflammation (>=5PMNs/HPF on a Gram-stained slide prepared from urethral exudates and/or a visible urethral discharge upon examination). Urine specimens will be collected and tested for Mycoplasma genitalium and Ureaplasmas. Each participant will receive a blinded packet of study medication. Participants will answer an enrollment questionnaire and will also receive a log to complete between visits to record information about treatment adherence, side effects, symptoms, and sexual activity. All subjects will be asked to return for evaluation 3 weeks after the initial clinic visit. Subjects who test positive for M. genitalium and/or Ureaplasmas at the initial clinic visit will also be asked to return for a third study visit, 6 weeks following the initial clinic visit. During follow-up visits, participants will answer a follow-up questionnaire and will be re-evaluated for signs of urethritis. Those who were initially positive for M. genitalium and/or Ureaplasmas will be re-tested for these organisms. Study participants with signs and/or symptoms of urethritis or who test positive for M. genitalium or Ureaplasmas at the follow-up study visit will receive another blinded treatment packet containing the alternate medication. Those who require additional treatment at the 6-week visit will be asked to return for a fourth follow-up study visit at 9-10 weeks. Study participants who did not test positive for M. genitalium or Ureaplasmas at the initial clinic visit, but who continue to demonstrate signs and/or symptoms of infection at their single follow-up study visit will treated according to clinic standard of care (after the study clinician unblinds their randomly-assigned treatment regimen). |

| NCT00829764 ↗ | Doxycycline Monohydrate 25 mg (5mL) Oral Suspension Under Fasting Conditions | Completed | Teva Pharmaceuticals USA | Phase 1 | 2006-10-01 | The objective of this single-dose, open-label, randomized, two-period crossover study was to compare the rate of absorption and oral bioavailability of a test formulation of doxycycline monohydrate 1 x 25 mg (5mL) oral suspension manufactured by IVAX Pharmaceuticals, Inc. and distributed by TEVA Pharmaceuticals USA to an equivalent oral dose of the commercially available reference product, Vibramycin Monohydrate® manufactured by Pfizer, Inc. following an overnight fast of at least 10 hours. |
| NCT00829790 ↗ | Doxycycline Monohydrate 25 mg (5mL) Oral Suspension Under Fed Conditions | Completed | Teva Pharmaceuticals USA | Phase 1 | 2006-10-01 | The objective of this study was to compare the rate of absorption and the oral bioavailability of a test formulation of doxycycline monohydrate 1 x 25 mg (5mL) oral suspension manufactured by IVAX Pharmaceuticals, Inc. and distributed by TEVA Pharmaceuticals USA to an equivalent oral dose of the commercially available reference product, Vibramycin Monohydrate® manufactured by Pfizer, Inc. Following an overnight fast of at least 10 hours, subjects consumed a standard high-calorie. high-fat breakfast meal. This standard breakfast meal began 30 minutes prior to each dose. |
| NCT01087476 ↗ | Double-blind-randomized,Placebo Controlled Trial for Chemotherapy-associated Oral Mucositis Using Doxycycline Hyclate | Unknown status | Instituto Nacional de Cancerologia de Mexico | Phase 2 | 2010-05-01 | Background. Mucositis is a complication of chemotherapy with no effective treatment. Aim.To evaluate the efficacy of sub-microbial doses of doxycycline hyclate in preventing the development of oral mucositis in patients with acute leukemia (AL) treated with induction chemotherapy. Hypothesis. Doxycycline hyclate administration in sub-microbial dosage will reduce the incidence of oral mucositis in patients with AL who receive induction chemotherapy. Methods. Double-blind, randomized, placebo-controlled clinical trial. At the Cancer National Institute (INCan), adult patients (> 18 years of age) with acute leukemia of recent diagnosis, scheduled to receive induction chemotherapy will be enrolled in the study. Written informed consent from the patients will be obtained preceding inclusion in the study. At baseline and 3-times per week, during 21-days, patients will have an oral examination performed using the Oral Mucositis Assessment Scale (OMAS), oral pain, difficulty to swallow, and salivary flow measurements will be recorded. A sample size of 164 subjects has been calculated, 74 subjects in each arm of the study. The primary end point of this study to evaluate the efficacy will be the proportion of patients treated with doxycycline or placebo without oral lesions associated with OM, during the 21 days of follow-up. Efficacy will be evaluated if the proportion of complete response (CR) is significantly higher than the proportion of events in the placebo group. Additional secondary endpoints will be the partial resolution of the oral lesions, the incidence of infections and the mortality in the study groups during the 21 days of follow-up. Results will be analyzed by using Chi-squared test and Wilcoxon-Mann-Whitney rank sum test. |
