Condition(s) targeted: HIV; AIDS

Intervention: EpivirĀ®, RetrovirĀ® and ViramuneĀ® (Drug); Lamivudine, Zidovudine and nevirapine (Drug); Lamivudine, zidovudine, nevirapine (Drug)

Phase: Phase 1

Status: Active, not recruiting

Sponsored by: Elim Pediatric Pharmaceuticals Inc.

Summary

The purpose of the study is to determine the bioavailability/bioequivalence of two pediatric formulations (tablet and reconstitutable suspension) of lamivudine/zidovudine/ nevirapine in comparison to an innovator product. Establishing the bioequivalence of a newly developed age-appropriate fixed dose combination of lamivudine/zidovudine/ nevirapine as an oral dispersible tablet or a reconstitutable suspension for children is invaluable for future product registration and availability of the products to children, thus filling the void in pediatric HIV/AIDS therapy.

Clinical Details

Official title: Phase I Three-way Crossover Bioequivalence Study of Pediatric Formulations of Lamivudine/Zidovudine/Nevirapine Using Healthy Adult Volunteers

Study design: Allocation: Randomized, Endpoint Classification: Bio-equivalence Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Bioequivalence between the tests and reference drugs

Detailed description: Volunteer Selection and Size: The International Conference on Harmonization (ICH) guideline E11 on clinical investigation of medicinal products in the pediatric population suggests that for relative bioavailability comparison of pediatric formulations, adult subjects may be used. Therefore, the study will be performed in a minimum of 24 healthy adult subjects. However, 29 healthy adults will be enrolled to allow for two possible drop-outs and for three subjects that may develop hypersensitivity to nevirapine which is known for its hypersensitivity side effect, in form of rashes. In anticipation of such reactions,10% more of the 26 subjects will be added to the group. This will make a total of 29 volunteers during the study. Advertisements announcing the study will be posted at the Bowen University Teaching Hospital two months before the commencement of the study to invite volunteers. Informed Consent Procedure: The volunteers will be screened using a questionnaire (see attached). The language of communication will be English or a local language used by the community. Researchers will explain to the volunteers on an individual basis, the nature of the study, what would be expected of them and their rights. Volunteers may choose to drop out of the study at any time without any restrictions. Volunteers will be informed that the screening procedure also includes physical examination and laboratory test. Following informed consent, using Consent to Participate Form (see attached) and counseling, volunteers may be enrolled for the study. A baseline laboratory tests for: packed cell volume, white blood cell count with differentiation, platelet estimation, liver function (aspartate aminotransferase [SGOT], alanine aminotransferase [SGPT]), renal function (serum creatinine), blood urea nitrogen (BUN), pregnancy test (females only), HIV/AIDS, and hepatitis B and C tests will be done two weeks prior to dosing. Volunteers may not consume alcohol, tobacco, caffeine containing products, herbal or other drugs during the study. Eligibility: The inclusion criteria are as follows: Adult males and females found normal on the basis of a pre-trial physical examination, medical history and the results of blood biochemistry and hematology tests; subject is competent and willing to sign informed consent form voluntarily after being given all the detailed information about the study; willingness to be hospitalized for a 24-hour intensive sampling period. Exclusion criteria:

- Hypersensitivity to study drugs, alcoholism, anemia, evidence of pregnancy

- Abnormal laboratory test; smokers;

- Any clinically significant diseases or findings during the screening medical history or

physical examination that, in the opinion of the investigator, may interfere with the study;

- Treatment with experimental or prescribed drugs within 30 days prior to the beginning

of the study Confidentiality: Volunteer's name as it appears on the questionnaire will be linked to an identification number. All other documents will have only the identification number instead of your name. The name will not be used in any public document. All written materials and consent forms will be stored in a locked file in the researcher's office. All materials will be destroyed by shredding five years after the completion of the research.
