Safety and Benefit Study of Droxidopa to Treat Patients With Intradialytic Hypotension
Completed · Phase 2 · Has a placebo group
Conditions studied: Intradialytic Hypotension
In brief
In clinical trials in Japan, droxidopa has been shown to be effective in affecting blood pressure changes upon orthostatic challenge in patients with autonomic dysfunction, as well as reducing the severity and frequency of symptoms of orthostatic hypotension in these patients. The efficacy of droxidopa in ameliorating symptoms in patients undergoing dialysis has also been demonstrated in the literature and clinical trials conducted in Japan. The current study will investigate the clinical efficacy of two different doses of droxidopa in patients with intradialytic hypotension over a 4 week treatment period with a placebo control. The clinical efficacy will be evaluated by changes in hypotension- related symptoms, as well as changes in blood pressure prior to, during and following, HD sessions as compared to their pre-treatment baseline values.

You may not qualify if…
- Currently taking ephedrine or midodrine;
- Patients taking ephedrine or midodrine may enroll after a minimum 7 day washout period
- Taking anti-hypertensive medication on the day of dialysis;
- Currently taking selective norepinephrine re-uptake inhibitors;
- Current known or suspected drug or substance abuse;
- Women of childbearing potential who are not using a medically accepted contraception;
- Subject Restrictions:
- Reproductive potential: Female subjects should be either post-menopausal (amenorrhea for at least 12 consecutive months), surgically sterile, or women of child-bearing potential (WOCP) who are using or agree to use acceptable methods of contraception. Acceptable contraceptives include intrauterine devices (IUDs), hormonal contraceptives (oral, depot, patch or injectable) and double barrier methods such as condoms or diaphragms with spermicidal gel or foam.
- For WOCP a urine/serum beta HCG pregnancy test must be conducted at screening and study termination, and a urine/serum pregnancy test must be conducted at baseline; the results must be negative at screening and at baseline. WOCP must be advised to use acceptable contraceptives throughout the study period and for 30 days after the last dose of investigational product. If hormonal contraceptives are used they should be taken according to the package insert. WOCP who are not currently sexually active must agree to use acceptable contraception, as defined above, if they decide to become sexually active during the period of the study and for 30 days after the last dose of investigational product.
- Sexually active males whose partner is a WOCP must agree to use condoms for the duration of the study and for 30 days after the last dose;
- Women who are pregnant or breast feeding;
- Known or suspected hypersensitivity to the study medication or any of its ingredients;
- Have active atrial fibrillation (within the last 6 months) or, in the investigator's opinion, have any other significant cardiac arrhythmia;
- Any other significant systemic, hepatic or cardiac illness;
- Have a history of closed angle glaucoma;
- Have a known or suspected malignancy (other than basal cell carcinoma);
- Patients with known gastrointestinal illness or other gastrointestinal disorder that may, in the investigator's opinion, affect the absorption of study drug;
- In the investigator's opinion, have clinically significant abnormalities on clinical examination or laboratory testing;
- In the investigator's opinion, are unable to adequately cooperate because of individual or family situation;
- In the investigator's opinion, are suffering from a mental disorder that interferes with the diagnosis and/or with the conduct of the study, e.g. schizophrenia, major depression, dementia;
- Are not able or willing to comply with the study requirements for the duration of the study;
- Have participated in another clinical trial with an investigational agent (including named patient or compassionate use protocol) within 30 days before the start of the study;
- Previous enrollment in the study.
