Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Does doxycycline prevent matrix metalloproteinase dependent tissue destruction in lymphangioleiomyomatosis (LAM) thus preserving lung function, exercise capacity and quality of life in LAM?;Secondary Objective: (1) determine the optimum dose of doxycycline needed to suppress MMP production (2) define the safety profile of doxycycline in LAM (3) provide evidence of efficacy and size of effect (4) determine the optimum design and logistics of future trials. ;Primary end point(s): Mean rate of change of FEV1/year over 24 months on doxycycline compared with placebo. | — |
