Eligibility:

Phase:
PHASE1
Brief Summary
The purpose of this study is to determine the maximum tolerated dose of nimodipine as well as the safety and tolerability of oral nimodipine in progranulin mutation carriers in preparation for longer ...
Detailed Description
8 people with a GRN gene mutation will be given escalating doses of oral nimodipine for four weeks, followed by the maximally tolerated dose for four weeks. To maximize enrollment, the trial will enro...
Eligibility Criteria
Inclusion
- Inclusion Criteria (all must be met):
- Signed and dated written informed consent obtained from the subject and/or the subject's caregiver in accordance with local IRB regulations
- Symptomatic GRN mutation carrier as defined by presence of known disease-associated GRN mutation confirmed by genetic testing and meeting international (2011) criteria for FTD (Rascovsky et al., 2011), Boeve (2003) criteria (B. F. Boeve, Lang, \& Litvan, 2003) for CBS, or Gorno-Tempini criteria (2011) for primary progressive aphasia (Gorno-Tempini et al., 2011) (gene carrier status known) OR
- Asymptomatic GRN mutation carrier (gene carrier status known) from family with known disease-associated mutation;
- Age: \>30
- MMSE ≥ 10 at screening visit.
- Judged by investigator to be able to comply with all study procedures
- In the opinion of the investigator, the patient will be compliant with the protocol and have a high probability of completing the study
- Lack of other recent, severe medical conditions.
- Exclusion Criteria(Any one of the following will exclude a subject from being enrolled into the study):
- Hypersensitivity or other contra-indication to nimodipine use
- Systemic autoimmune disease (such as rheumatoid arthritis, thyroid disease, or diabetes) that might alter progranulin levels.
- Regular use of systemic corticosteroids or other anti-inflammatory medication. NSAID use acceptable if on a stable dose for 30 days prior to screening and agrees to remain on same dose for duration of trial.
- Subject is pregnant, plans to become pregnant during course of study or has a positive urine pregnancy test.
- Unwilling to use two forms of contraception if not surgically sterile for duration of study.
- History of cancer (other than basal cell CA of skin) within 5 years.
- History of myocardial infarction, cardiac conduction block, arrhythmia or other significant cardiac illness in the opinion of the investigator (in consultation with a board certified cardiologist).
- History of peptic ulcer.
- Metabolic disease such as gout or poorly controlled diabetes.
- History of alcohol or substance abuse within 1 year prior to screening, if deemed clinically significant by investigator.
- Any current malignancy, or any clinically significant hematological, endocrine, cardiovascular, renal, hepatic, gastrointestinal or neurological disease. If the condition has been stable for at least the past year and is judged by the investigator not to interfere with the patient's participation in the study, the patient may be included.
- CT or MRI evidence of any of the following: hydrocephalus, stroke, space-occupying lesion, cerebral infection or any clinically significant CNS disease other than FTD, CBS, or progressive aphasia.
- Systolic blood pressure greater than 180 or less than 90 mm Hg. Diastolic blood pressure greater than 105 or less than 50 mm Hg.
- Abnormal ECG at screening and judged to be clinically significant by the investigator and/or board certified cardiologist.
- Use of investigational drugs or participation in investigational drug study within 30 days of screening or 5 half lives of the previous investigational drug, whichever is longer.
- Use of nimodipine within the 4 weeks prior to start of trial.
- Within 4 weeks of beginning or during the course of the study, concurrent treatment with calcium channel antagonists, blood thinners (e.g. clopidogrel, warfarin), or statin medication in combination with niacin.
- Clinically significant lab abnormalities at screening, including creatinine ≥ 1.7, B12 below laboratory normal reference range, or TSH above site's laboratory normal reference range. Subjects with abnormal B12 or TSH levels at screening may be included per investigator's discretion.
- Contraindication to MRI examination for any reason (e.g., severe claustrophobia, ferromagnetic metal in body).
