Rare fat disorder drug under microscope: new safety data emerges

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Provision of informed consent prior to any study specific procedures. If \<18 years of age, has a parent or guardian able to read, understand, and sign the Informed Consent Form (ICF) and a Child Assent form, communicate with the Investigator, and understand and comply with protocol requirements. Adolescent patients must also read and understand the Child Assent Form. If the child is too young or unable to read, then the Child Assent form must be explained to the child. 2. Female and/or male patients ≥1 years of age. 3. Physician-confirmed diagnosis of congenital or acquired generalized lipodystrophy and will begin treatment with MYALEPT for the first time. 4. Negative pregnancy test (urine or serum) for female patients of childbearing potential. 5. Female patients of childbearing potential must be 1 year postmenopausal, surgically sterile, or be willing to use an acceptable method of contraception (an acceptable method of contraception is defined as a barrier method in conjunction with a spermicide) for the duration of the study (from the time they sign consent). In addition, oral contraceptives, approved contraceptive implant, long-term injectable contraception, intrauterine device, or tubal ligation are allowed. Oral contraception alone is not acceptable; additional barrier methods in conjunction with spermicide must be used. 6. Male patients must be surgically sterile or be willing to use an acceptable method of contraception (defined as barrier methods in conjunction with spermicides) for the duration of the study (from the time they sign consent). 7. Patients who are blood donors should not donate blood during the study and for 3 months following their last dose of metreleptin. Exclusion Criteria: 1. Involvement in the planning and/or conduct of the study (applies to both Aegerion staff and/or staff at the study site.) 2. Previous treatment with metreleptin. 3. Participation in another clinical study with an investigational product during the last 6 months. 4. Patients with prior severe hypersensitivity reactions to metreleptin or to any of the product components. 5. Known to have tested positive for human immunodeficiency virus, are immunocompromised, or are receiving immunomodulatory drugs. 6. Known history of drug or alcohol abuse within 1 year of screening. 7. Creatinine clearance \<30 mL/min using institutional standards: e.g., calculated using Cockcroft-Gault formula for patients ≥18 years of age; calculated using Schwartz equation for patients \<18 years of age. 8. For women only - currently pregnant (confirmed with positive pregnancy test) or breast-feeding. 9. Any condition where, in the opinion of the Investigator, participation in this study may pose a significant risk to the patient or could render the patient unable to successfully complete the study.
