Infertility clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Effect of Low Level Laser Therapy on Endometrial Cells: An In Vitro Study

LLLT

Start date: n/a
Phase: N/A
Study type: Expanded Access

The human endometrium is an extremely sensitive target. LLLT can enhance the proliferation rate of various cell lines, it produces higher rates of ATP, RNA, and DNA synthesis in stem cells and other cell lines. Thus, LLLT improves the proliferation of the cells without causing any cytotoxic effects. The aim of this work is to assess the ability of low level laser therapy in enhancing endometrial proliferation and increasing endometrial receptivity. A number of 120 human endometrial samples will be studied, and will be collected from 40 infertile women attending the infertility clinic at NRC. Each human endometrial sample will be divided into 3 plates, in order to establish 3 main groups of 40 culture plates for single laser exposure group versus 40 culture plates for multiple laser exposure group and 40 tissue culture plates for control samples, thus a total of 120 tissue culture plates will be studied, the study groups will be exposed to low level laser therapy and compared to their matched controls.. Assessment of number and size of cells after LLLT as a marker of normal proliferation and b) The expression of Integrin aVB3 "alpha v B3", MUC-1 and LIFand the development of pinopodes on the surface of epithelial cells as markers of endometrial receptivity and the detection of PTEN tumor suppressor gene as a marker of abnormal proliferation or premalignant condition will be performed to assess the effect of LLLT on the endometrial cell culture. This study might offer a new therapeutic modality which might increase endometrial thickness and enhance receptivity .
