Brief Title  ICMJE N-Acetyl Cysteine and Aspirin as an Adjunctive Treatment for Bipolar Disorder
Official Title  ICMJE A Double-blind Randomized Placebo-controlled Study of Aspirin and N-acetyl Cysteine as Adjunctive Treatments for Bipolar Disorder Patients (SMRI 11T-009)
Brief Summary

We propose to conduct a double-blind placebo-controlled trial with a widely available and prototypical non-steroidal anti-inflammatory agent, aspirin, and an antioxidant agent, NAC, involving symptomatic Bipolar Disorder type I and II patients having a depressive or mixed episode currently. This will be the first controlled study to test the hypothesis that aspirin and NAC, by themselves or in combination, will be beneficial in treating depression in bipolar disorder patients and in promoting mood stabilization.

Our study has the following Aims:

Aim I - Examine efficacy of aspirin in treating depression in bipolar patients in a double-blind placebo-controlled add-on design; Aim II - Examine efficacy of NAC in treating depression in bipolar patients in a double-blind placebo-controlled add-on design; Aim III - Examine efficacy of combined treatment with aspirin and NAC looking for synergistic, potentiating effects; Aim IV - Examine the role of markers of neuroinflammation, as possible mediators or modulators in therapeutic response in the treatment of depression in patients with Bipolar Disorder.

Detailed Description

study design: BD type I or II patients (n=160), on a depressive or mixed episode, who were on therapeutic doses of any of the commonly utilized mood stabilizing agents (lithium, anticonvulsants, atypical antipsychotics) for at least one month and who were still symptomatic (MADRAS >20) will be enrolled. Patients will be randomly assigned to orally receive one of 4 conditions: aspirin 1000 mg (2 capsules of 500 mg) qam, NAC 1000 mg (2 capsules of 500 mg) bid, combined aspirin and NAC at same doses as given individually or matched placebo, as an add-on medication to their ongoing treatment regimen, for an 16-week double-blind trial. After the first 8 week of the double blind treatment, the responders will keep taking the same study drug, whichever it is. And the non-responders will be re-randomized for one of the other three groups of study drugs they haven't tried yet.

Procedures to be used:

The study will be carried out at the outpatient clinics affiliated with the UT Health Science Center at Houston. After signing informed consent, patients will be submitted initially to a structure psychiatric diagnostic interview(SCID-I) to confirm the psychiatric diagnosis, followed by a physical examination and routine labs (CBC, liver function tests, electrolytes, kidney functions tests, thyroid function tests, urinalyses) to rule out relevant medical problems. Physically healthy BD patients on psychotropic medications or combinations will be enrolled and randomly assigned to receive, orally, aspirin 1000 mg qam, NAC 1000 mg bid, combination of aspirin 1000 mg qam and NAC 1000 mg bid, or placebo. The study drugs doses will remain the same for the duration of the study.

If patients qualify for the study initially based on SCID-I interview, physical examination, and routine labs (CBC, liver functions tests, electrolytes, kidney function tests, thyroid function tests, and urinalyses), but are not currently taking an approved psychotropic medication or combinations they are eligible to participate in a lead-in phase. This phase would be starting at their screening visit and last approximately 6 to 8 weeks depending on the patient's mood. During this lead-in phase, either the PI or Co-PI will evaluate the patient and prescribe either Lithium or Depakote. The patient will be monitored during this treatment phase by the PI or Co-PI and will return after two weeks for an evaluation. The evaluation will include the Columbia-Suicide Severity Rating Scale(CSSR-S) to assess risk of suicide, the Montgomery-Asberg Depression Rating Scale(MADRAS) to assess the severity of depression and the UKU side effects rating scale. If the patient is prescribed lithium, their lithium levels will be tested. The patient will continue to follow up every two weeks. At the 4 week visit, the patient will also come in for evaluation (CSSR-S MADRAS and UKU side effects rating scale).

At the 6 week visit, the patient will be re-evaluated for the double-blind study trial. If the patient has been on an adequate dose of the psychotropic medication for at least 4 weeks and score greater than 20 on the Montgomery-Asberg Depression Rating Scale (MADRS), then they will be enrolled.

If they do not meet inclusion criteria at the week 6 lead-in phase visit, they will return at Week 8 and be re-evaluated. PI and Co-PI will continue to prescribe the psychotropic medication throughout the lead-in phase (up to 8 weeks) and through the trial (up to 16 weeks).

During the lead-in phase participants will not be compensated. They will receive a voucher for their parking for each visit. They will be responsible for filling and paying for all prescriptions in both the lead-in phase and through the trial (up to 16 weeks).

Upon completion of the first 8-week double-blind trial, patients who responded to the active medication will continued on the same study drug for an additional 8 week double-blind treatment. The non-responders to one of the study drugs will be re-randomized for one of the other three groups of study not received and will remain in treatment for an additional 8 week double-blind treatment. Treatment response will be defined as improvement in the MADRS scores of at least 50%.

During the first 8-week trial, patients will be seen at weeks 0, 1, 2, 3, 4, 6 and 8 for clinical assessment and mood ratings. During the continuation trial, they will be seen at weeks 8, 10, 12, 14 and 16.

Routine labs (CBC, liver function tests, electrolytes, kidney functions tests, thyroid function tests, urinalyses) will be repeated at week 8 and week 16.

The main outcome measure for the study will be the scores on the Montgomery-Asberg Depression Rating Scale, MADRAS, which assess the severity of depressive symptoms. All patients will also be assessed with the Young Mania Rating Scale, YMRS,which assess the severity of manic symptoms. the Clinical Global Impression-Bipolar version,severity of illness, CGI-S,which is used to measure the severity of depressive, mania and severity overall. And, the UKU side-effects scale, which will assess all the side effects related or not to the study group treatments. In all visits, patients will be seen by the study psychiatrist and the research staff will complete mood ratings with the MADRAS, YMRS, CGI-BD, and the UKU side-effects scale.

At baseline (before randomization), week 8 and week 16 blood will be sampled for proinflammatory markers (C-reactive protein, soluble interleukin (IL)-2 receptor, IL-6 and tumor necrosis factor (TNF)-alpha), and oxidative stress markers (superoxide dismutase activity and catalase activity, serum thiobarbituric acid reactive substances (TBARS), which have been reported to be elevated in BD patients. These blood samples will be stored for possible future research on biomarkers or future genetic studies for up to 20 years, for use in pharmacogenetic research during this 20 year timeframe. The samples will be stored at the Wet Lab, in a double locked -80 degrees freezer, at BBSB, Department of Psychiatry at University of Texas Health Science Center at Houston. (1941 East Road, suite# 3170 Houston-TX 77054) for future use studying factors of Bipolar Disorder. When (or before) the 20 year period ends, the blood sample will be destroyed.

At the screening visit, week 8, and week 16 we will also be testing the Lithium levels in all patients that have been prescribed and currently taking the medication for study purposes. This extra test will be conducted for the safety of the patient and more Lithium level tests can be ordered under the PI's discretion throughout the 16 week trial.

Risks and potential benefits:

Aspirin is a safe medication for administration to humans and is approved by the FDA as an anti-inflammatory and analgesic agent. The dose proposed for this study is within the safety range as per medication package. Its side-effect profile is overall very favorable and it has met widespread use worldwide over the past decades. The main safety issues relate to the possibility of gastrointestinal complications, which are rare (and will be closely monitored in the weekly or biweekly visits that the study requires), and the propensity to interfere with coagulation and cause consequent bleeding (which will be prevented by excluding any individuals on use of anticoagulants or with active bleeding problems). There were a few case reports and small case series with other non-steroidal anti-inflammatory agents suggesting worsening of depressive symptoms related to treatment (e.g., indomethacin, ibuprofen, naproxen), but those were uncontrolled reports with individuals who suffered from other medical illnesses (rheumatologic diseases).

For our proposed trial, because some patients may be on lithium at the time they start on aspirin, we will exclude individuals with pre-existing cardiac and kidney disease. For patients on lithium, we will carefully monitor their serum lithium levels every two weeks during the course of the trial. Therefore, at the doses that are being proposed we do not anticipate any significant problems related to safety of the proposed intervention.

NAC is a safe compound that is commonly available and utilized over-the-counter. In a recent study the tolerability was excellent and main side effects included changes in energy level, headaches, heartburn and joint pain

Blood Draws: When the blood is drawn, there may be some minimal discomfort and/or bruising. Infection, excess bleeding, clotting, or fainting is also possible, although unlikely. All usual precautions will be taken to prevent these possibilities and these risks will be minimized by using trained staff to perform the blood draws

Subjects will be carefully monitored. If a subject's condition worsen to the point that he/she might become suicidal or severely depressed, we will terminate the subject's participation in the study and referred to his/her psychiatrist for psychiatric treatment.

Breach of Confidentiality: Every effort will be made to protect the subject identity and information during the study. All lab work and scan reports will be de-identified and the medical records will be protected. However, there is a small chance that the subject information may be viewed by someone that is not involved in the research study.

The study drug must be taken only by the person for whom it has been prescribed, and it must be kept out of the reach of children or persons of limited capacity to read or understand.

By sharing your sample with the study doctor, there is a risk of the possible loss of the subject privacy. Although no identifiable (name, address, etc.) information will be shared with others outside of this research project. The clinical information obtained from subjects will be part of their medical records and maintained at UT Center of Excellence on Mood Disorders, in the Department of Psychiatry at UTHSC-H, in facilities with adequate safeguards for the protection of confidentiality. The research data will be collected and recorded using only arbitrary code numbers for identification, in order to safeguard the confidentiality. All data will be kept in a secure area. Only the members of the UT Center of Excellence on Mood Disorders research group, who will get approval from CPHS, will have access to the data files, or to the master list for the codes. For publications purposes, the patients will be designated only by their assigned codes.

These blood samples, for use in pharmacogenetic research during this 15 year timeframe, samples will be stored at the Wet Lab, in a double locked -80 degrees freezer, at BBSB, Department of Psychiatry at University of Texas Health Science Center at Houston. (1941 East Road, suite# 3170 Houston-TX 77054) The possibility exists that the subject information may be taken and used for reasons outside of this project. The United States' Genetic Information Nondiscrimination, Act (GINA) of 2008, does not allow for employers or health insurance companies to discriminate against the research subject based on his/her genetic information. This means that health insurance companies or employers are NOT ALLOWED BY LAW to ask or use any of the subject genetic information (DNA, RNA, etc.) gained through testing to make decisions that affect the subject or hisher family's health coverage or income in a negative way

Importance of knowledge that may reasonably be expected to result:

The study will examine possible novel mechanism of actions with modulation of inflammatory mechanisms and oxidative stress and could result in the development of novel, low cost, safe and widely available treatments for BD patients who have not responded to other commonly utilized alternatives

If the subject is a female and able to become pregnant, a urine pregnancy test will be performed which must be negative prior to enrolling into the study, and the subject must agree not to become pregnant during the study. Urine pregnancy tests will be performed at Screening visit and week 8. The study staff will review adequate birth control methods with the subject and will remind her that she should not become pregnant during the study. Appropriate methods of birth control include: hormonal contraceptives (such as birth control pills, patches, and implants), barrier methods (such as a condom and diaphragms and spermicidal foam or jelly, surgical (hysterectomy or tubal ligation) or intrauterine device (IUD). The subject will be instructed to notify the study doctor immediately if there is a chance that she has become pregnant.

Also, if the subject is breast-feeding an infant or plan on breast-feeding an infant, she must notify the study doctor. It is not known if this drug is excreted in human milk; therefore, breast-feeding is not permitted during the study.
