Conditions: Lymphangioleiomyomatosis
Keywords: LAM TSC lymphangioleiomyomatosis
Allocation:  | Intervention model: SEQUENTIAL
Enrollment: 14
Healthy volunteers: no

Brief summary:
Specific Aim 1: To investigate whether, in Lymphangioleiomyomatosis (LAM) patients, the combination of sirolimus and hydroxychloroquine is safe and well tolerated

Specific Aim 2: To investigate whether, in LAM patients, 6 months of combination therapy with sirolimus and hydroxychloroquine results in improvement of indicators of disease, and whether the gains are sustained after stopping therapy.

Specific Aim 3: To investigate the potential role of a LAM-specific peripheral blood signature to predict rates of disease progression and determine responsiveness to combination therapy.

This will be a phase I dose escalation study of the combination of sirolimus (2 mg adjusted to keep trough levels between 5-15 ng/ml) and hydroxychloroquine (200 mg or 400 mg) taken orally daily. Up to 18 adult women with LAM will be enrolled.

Detailed description:
This will be a phase I dose escalation study of the combination of sirolimus (2 mg adjusted to keep trough levels between 5-15 ng/ml) and hydroxychloroquine (200 mg or 400 mg) taken orally daily for 6 months. The study is to be conducted at 2 sites. Up to 18 adult women with LAM will be enrolled, and each recruiting site will recruit between 8-12 subjects. The protocol will use the following eligibility criteria.

Arms:
arm 1: Subjects will take Sirolimus at an initial dose of 2mg followed by dose adjustment to keep Sirolimus trough levels between 5-15ng/ml consistent with the effective dose in the MILES trial. In addition to Sirolimus subjects will receive Hydroxychloroquine at 200 mg daily for 6 months. Once safety is established at the lower dose ("Sirolimus" and "Hydroxychloroquine" 200 mg), subjects enrolled henceforth will receive Sirolimus and Hydroxychloroquine 400 mg (200 mg twice a day) for 6 months.

Interventions: intervention 1: "Sirolimus" and "Hydroxychloroquine" 200 mg intervention 2: "Sirolimus" and "Hydroxychloroquine" 400 mg
Intervention descriptions: intervention 1: This will be a phase I dose escalation study of the combination of "Sirolimus" (2 mg adjusted to keep trough levels between 5-15 ng/ml) and "Hydroxychloroquine" 200 mg taken orally daily. intervention 2: Once safety is established with the lower dose, (Sirolimus and Hydroxychloroquine 200 mg), subjects will receive Sirolimus 2 mg (adjusted to keep trough levels between 5 to 15 ng/ml) and hydroxychloroquine 200 mg twice a day.
