NCT02902133 | Withdrawn Phase 2 FDA Drug

• 1 other identifier: 20150742
• Study Type: interventional
• Target: N/A
• Locations: 0 countries
• Sites: N/A

Brief Summary

The purpose of this research is to test the use of Acetazolamide in preventing post-operative cerebrospinal fluid leak in patients having endoscopic skull base surgery (it is a surgery performed through the nose and sinus).

Conditions

Cerebrospinal Fluid Leak

Outcome Measures

Primary Outcomes (1)

• Incidence of CSF Leakage

  Occurrence of postoperative CSF leak within 30 days of surgery confirmed on clinical exam as well as on CT scan, endoscopic visualization, or confirmation via beta transferrin testing.

  30 days

Secondary Outcomes (1)

• Incidence of suspected drug adverse events

  14 days

Study Arms (1)

Acetazolamide Arm

OTHER

Acetazolamide 500 mg twice per day for 5 consecutive days post standard-of-care endoscopic skull base surgery

Drug: Acetazolamide

Interventions

Acetazolamide DRUG

Acetazolamide 500 mg by mouth twice per day for 5 days

Also known as: Diamox

Acetazolamide Arm

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Elective transsphenoidal resection of a tumor expected to result in an intraoperative high flow CSF leak; such tumors include craniopharyngioma, meningioma, and Rathke cleft cyst.
• Elective transsphenoidal resection of a pituitary adenoma, with BMI \>25, or with observed low or high flow CSF leak during surgery, conferring an elevated risk of postoperative CSF leak.
• Patients who voluntarily sign Informed Consent
• Male subjects and female subjects of childbearing potential and at risk for pregnancy must agree to use a highly effective method of contraception during study treatment and for at least 1 month after stopping study treatment. Male subjects should refrain from donating semen during treatment and 1 month after stopping treatment.

You may not qualify if:

• Adults unable to consent
• Individuals who are not yet adults (infants, children, teenagers)
• Pregnant women
• Prisoners
• Patients with prior adverse reactions to acetazolamide or who are taking aspirin concomitantly (which may increase the risk of adverse reactions to acetazolamide)
• Patients with moderate to severe chronic obstructive pulmonary disease (which may increase the risk of adverse effects of acetazolamide)
• Acetazolamide therapy is contraindicated in situations in which sodium and/or potassium blood serum levels are depressed, in cases of marked kidney and liver disease or dysfunction, in suprarenal gland failure, and in hyperchloremic acidosis.
• It is contraindicated in patients with cirrhosis because of the risk of development of hepatic encephalopathy
• Sulfonamide allergy
• Pregnant females, breastfeeding females, and males and females of childbearing potential who are unwilling or unable to use a highly effective method of contraception
