Directed Research/ Directed Study Registration
Under the direction of a faculty member, students may earn Directed Research or Directed Study credits for special projects. Occasionally special topics classes are also offered under Directed Study course numbers. University guidelines indicate the following expectations for one credit of Directed Research or Directed Study:
- 15 hours/semester of meeting time with faculty director
- 2 hours/week outside of that meeting time
- Thus 1 credit = 3 hours/week = 45 hours/semester
Generally it would be difficult for a student to take more than 1 credit of Directed Research or Directed Study per semester, given the above time requirements.
Directed Research and Directed Study may be taken on the A/F or S/N grading basis. The student and faculty director should discuss which grading basis to use before the student registers.
Students may count Directed Research and Directed Study credits toward the required 10 credits of electives (even if taken on the S/N grading basis).
To register for Directed Research and Directed Study, students need faculty permission. After discussion with a faculty member who agrees to direct the research or study, the faculty member should email his or her permission to OSS: Amy Renne (Duluth campus) at firstname.lastname@example.org or Peter Haeg (Twin Cities campus) at email@example.com, who will register the student for the Directed Research or Study. The email should also specify the number of credits and the grading basis.

ESETT: Established Status Epilepticus Treatment Trial (Pharmacology Core)
ESETT is multicenter, randomized, blinded, comparative effectiveness study of fosphenytoin (FOS), valproic acid (VPA) or levetiracetam (LVT) in the emergency department treatment of patients with benzodiazepine (BDZ) refractory status epilepticus (SE). The main objective is to determine the most effective and/or least effective treatment of BDZ refractory SE among patients older than 2 years. The primary outcome is clinical cessation of status epilepticus, without recurrent seizures, life-threatening hypotension or cardiac arrhythmia, or use of additional anti-seizure medications within 60 minutes of the start of study drug infusion. The drug dosing regime in ESETT is weight-based, patients weighing < 75Kg receive FOS 20 mg/Kg, or VPA 40 mg/Kg, or LVT 60 mg/Kg, but those weighing more than 75 Kg receive fixed doses of 1500 mg FOS, 3000 mg VPA and 4500 mg LVT. As an ancillary study, we are proposing the evaluation of drug exposure and response relationships.

PK-PD of IV Allopregnalone in Dogs with Epilepsy
This project involves the use of dogs with epilepsy to characterize the pharmacokinetic and pharmacodynamic properties of approved and investigational antiseizure drugs (ASDs). The canine epilepsy model permits studies on the differential effects of ASDs on behavior, sleep, and EEG as well as the relationship between drug exposure (e.g. plasma drug concentrations) and effects such as changes in sleep or EEG patterns. Allopregnanolone is a naturally-occurring neurosteroid that is a positive allosteric modulator of synaptic and extrasynaptic GABAA receptors. A Phase III clinical trial is evaluating allopregnanolone administered by continuous intravenous (IV) infusion as a treatment for super-refractory status epilepticus (SE) in patients under general anesthesia in an intensive care setting. We hypothesize that allopregnanolone possesses the requisite pharmacokinetic (PK) and pharmacodynamic properties to support its use as an initial IV or intramuscular (IM) bolus treatment for SE. Our study objectives are to assess the tolerability and develop a PK model of allopregnanolone following a 5 minute IV infusion and an IM injection, both clinically applicable regimens for the initial treatment of SE.

Development of Water-Soluble Benzodiazepine/Converting Enzyme for Intranasal Delivery Systems for Treatment of Seizure Emergencies
The goal of this project is to develop a highly water-soluble benzodiazepine prodrug intended for nasal administration that undergoes rapid metabolism in nasal epithelium or blood to an active drug. Such a compound would permit formulation of a highly concentrated drug solution capable of delivering clinically-relevant doses in small volumes (i.e. < 200 microliters) and which would cause minimal local tissue irritation and injury. Target mechanisms for biotransformation are those mediated by enzymes known to be present in nasal tissue. Compounds will be evaluated for rate of biotransformation and permeation using in vitro cell cultures. Those showing the most promise will be studied in rats and then, in dogs with epilepsy that have implanted intracranial EEGs.

Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx)
Epileptogenesis is common after traumatic brain injury (TBI)2 and begins early, offering a window of opportunity to test the efficacy of potential antiepileptogenic therapies. In order to design economically feasible clinical trials of such therapies it will be necessary to identify reliable biomarkers that: 1) predict later Post traumatic Epilepsy (PTE), to enrich the subject population; 2) stage the epileptogenic process, to determine the timing of intervention; and 3) diagnose epilepsy, to provide surrogate markers of outcome. To date promising electrical, imaging, and other biomarkers of epileptogenesis after TBI in animal models, including patholgical high frequency oscillations (pHFO) and repetitive pathological high frequency oscillations (RpFHOs) have been identified. The primary aim of the study is to perform prospective multicenter combined scalp and depth cEEG monitoring in moderate-severe TBI patients to determine if the occurrence of specific EEG changes, such as seizures, pHFOs and RpHFOs, predict later PTE. Our aims are to evaluate using pharmacokinetic and pharmacodynamic modeling and simulation to evaluate potential therapeutic agents to treat PTE.

MicroRNAs as Novel Biomarkers in Prolonged Seizures: Potential for Early Identification of Epilepsy
In this study, we will use a “two-hit” mouse model of epileptogenesis to understand the effect of seizures on miRNA expression in different brain regions. Seizures in immature animals cause subtle functional changes without causing cell death; however, this first hit (early seizure) can drastically alter the response to repeated seizures (second hit) later in life. This mimics the clinical characteristics of children with prolonged seizures. Thus a “two-hit” approach is a clinically relevant model of epilepsy and examining microRNA expression in brain and blood can provide information on the utility of microRNAs as diagnostic and prognostic biomarker of epilepsy.

Circulating MicroRNAs as Potential Biomarkers for Epilepsy
The long term goal is to evaluate the potential use of circulating microRNAs as clinical biomarkers in epilepsies. In this project, we will examine the temporal variation in blood microRNA expression following seizures in canines with naturally occurring epilepsy. Towards this end we will collect blood samples from these dogs prior to and immediately after a seizure episode at different time points. Circulating microRNAs will be analyzed using small RNA sequencing approach to understand changes in expression following a seizure.

MicroRNAs as Clinical Biomarkers to Understand Phenotypic Heterogeneity in Tuberous Sclerosis Complex
Tuberous Sclerosis Complex (TSC) is a multisystem genetic disorder due to mutations in either TSC1 or TSC2 gene resulting in variable phenotypic expression. Epilepsy is the most common presenting symptom in TSC with approximately one-third of patients developing intractable epilepsy.The objective of this project is to determine circulating microRNA expression signatures in patients with TSC. We hypothesize that in comparison to healthy individuals, blood samples from patients with TSC have a unique miRNA expression signature. The dysregulated miRNAs can potentially cause differential gene expression contributing to the varied phenotypic spectrum in adults with TSC, including intractable epilepsy.

Development of IV Baclofen for Prevention and Management of Baclofen Withdrawal Syndrome
This project is directed at developing a new therapy to treat the symptoms associated with acute withdrawal of baclofen, a drug used to treat spasticity. The acute withdrawal syndrome can occur when spinal cord infusion of baclofen by pump is interrupted due to pump dysfunction, catheter dislocation, or site infection or when oral baclofen is interrupted because of a patient’s inability to take medications by mouth. Fewer than 5,000 patients per year experience baclofen withdrawal syndrome. In addition, there are circumstances when interruption of oral baclofen therapy is anticipated (such as elective major surgery), and substitution with intravenous medication would reduce the risk of developing withdrawal.

Lorenzo's oil in the Treatment of Adrenoleukodystrophy
X-linked adrenoleukodystrophy (ALD) is a genetic disorder leading to accumulation of saturated very long chain fatty acids (VLCFAs; mainly C26:0) in tissues. This accumulation causes demyelination of neurons in the brain and adrenal dysfunction. Childhood cerebral ALD (CCALD) is the most severe and devastating form of this disease and affects school-age boys, leading to death in 2-3 years. Lorenzo’s oil (LO) is believed to competitively inhibit the elongation of long chain fatty acids to VLCFAs and clinical studies have shown a reduction in plasma VLCFAs in patients receiving LO. Additionally, literature suggests LO may reduce the development of cerebral involvement in ALD children, but studies on outcomes are conflicting. This is partially due to variability in dosing across studies and a complete lack of information on the pharmacokinetics and pharmacodynamics that characterize the dose-response relationship. The primary objective of this project is to determine the pharmacokinetics of erucic acid (a component of LO) in patients with X-linked ALD. This information will help optimize LO dosing in order to obtain desirable outcomes.

Improved Therapy for Late-stage Adrenoleukodystrophy
Childhood cerebral adrenoleukodystrophy (c-ALD) is an X-linked peroxisomal disorder affecting approximately 20,000 boys that results in demyelination of the CNS and early death in affected boys. Hematopoietic stem cell transplantation (HSCT) halts disease progression and extends life when c-ALD is diagnosed and treated at an early stage. There is, however, no known effective therapy for late-stage c-ALD although HSCT is offered at some centers. Survival and neurological outcomes are significantly worse in late-stage as compared to early-stage disease. N-acetylcysteine (NAC) is an antioxidant that reduces free radicals and facilitates glutathione biosynthesis. Our research team administered NAC to reduce oxidative damage and potentially render late-stage disease amenable to HSCT. The results indicate that IV NAC therapy, in conjunction with a reduced intensity transplant, significantly improves survival of boys with late stage-disease as compared to HSCT alone. Our studies are focusing on NAC clinical pharmacology and include both clinical and cell-based in vitro research . The goal of our research is to develop safer, more effective therapies for c-ALD including use of NAC as preventive therapy in children with early-stage disease.

Validation of Testing for Emerging Cerebral Adrenoleukodystrophy to Enable Clinical Trial Readiness– Oxidative Stress
The primary objective of this project is to gain critical information regarding the early evolution of cerebral disease in adrenoleukodystrophy (ALD). Childhood cerebral ALD (ccALD) is a progressive, debilitating and ultimately lethal form of ALD. The University of Minnesota treats more patients with ccALD than any in the world, and it is clear that we need to improve outcomes for these patients. We have not previously had the opportunity to gather prospective data in a sufficiently large cohort of boys with ALD prior to the onset of cerebral disease to study the evolution of ccALD. However, with the emergence of newborn screening for ALD this will now prove feasible.

Oxidative Stress-related Biomarkers in Gaucher Disease: a Preliminary Study
The primary objective of this study is to evaluate oxidative stress in patients with Gaucher disease using a series of biomarkers and correlate with clinical diagnostic biomarkers. Additionally, the relationships between oxidative stress and variables including therapy or intervention (for example ERT, SRT) and disease severity will be evaluated. We hypothesize that compared to healthy individuals subjects with GDI will have increased oxidative stress which can be normalized by intervention.

Role of Oxidative Stress and Inflammation in Type 1 Gaucher Disease (GD1): Potential Use ofAntioxidant/Anti-inflammatory Medications
The primary objective of this study is to characterize oxidative stress and inflammation in the blood and brain of individuals with GD1 and determine whether these factors can be altered with orally administered N-acetylcysteine (NAC). Additionally, correlations between peripheral (plasma or red blood cell) concentrations of NAC, cysteine, and glutathione with central (brain) glutathione levels will be evaluated in subjects with GD1.NAC and glutathione pharmacokinetics will also be characterized in this population with the intent to construct models linking pharmacokinetics with biomarker changes.

Effects of Yoga on Oxidative Stress, Motor Function and Psychosocial Well-being in Individuals with Parkinson’s Disease
Parkinson’s disease (PD) is a progressive neurodegenerative condition, in which motor and nonmotor features are currently not being sufficiently managed. Although the pathology of PD is complex, oxidative stress is recognized as a potential factor in the pathogenesis of PD. Hatha yoga has been shown to reduce oxidative stress in people with chronic health problems such as hypertension and diabetes; and improve gait, physical function, and quality of life in people with neurological disorders such as stroke and multiple sclerosis, however, studies carried out on the effects of yoga in PD are sparse. It is crucial to assess whether yoga is able to improve symptoms and alter the underlying biology of PD. The purpose of this study is to assess the effect of yoga on measures of oxidative stress, motor function, and psychosocial well-being as well as the feasibility and acceptability of implementing a yoga program in PD subjects.

Oral UDCA in Parkinson’s disease
We are interested in understanding the bioenergetic impairments that underlie Parkinson’s disease (PD) and evaluating treatments that may improve abnormal mitochondrial function that is present in PD. High field - 7 tesla (T) - magnetic resonance spectroscopy (MRS) is able to non-invasively assess for changes in brain energetics and will be used to evaluate the effects that repeated oral doses of the mitochondrial enhancer ursodeoxycholic acid (UDCA) has on brain bioenergetics derived from MRS measurements. The primary aim of the study is to measure plasma UDCA levels in individuals with PD at baseline and after four weeks of repeated high doses of oral UDCA (50mg/kg/day) and combine results obtained using MRS brain scans along with peripheral measurements of bile acids (e.g., total UDCA). Secondary aim of the study is to characterize oral UDCA pharmacokinetics and develop a pharmacokinetic/pharmacodynamic model to characterize the relationship between peripheral measurements of UDCA (and associated conjugates) and peripheral measures and/or central (brain) bioenergetic measurements.

Intranasal naloxone for treatment of impaired awareness of hypoglycemia
Recurrent exposure to iatrogenic hypoglycemia in patients with insulin treated diabetes can lead to development of impaired awareness of hypoglycemia (IAH). Naloxone- an opiod receptor antagonist has been shown to modulate hormonal response during hypoglyceamia and may play a role in the treatment of impaired awareness of hypoglycemia (IAH).This is a single center, single blind randomized cross-over design trial to evaluate intranasal nalaxone therapy for prevention and treatment of IAH. Secondary objective of this project is to characterize naloxone pharmacokinetics following multiple administrations. A 4mg dose of Narcan (naloxone hydrochloride) intranasal spray will be administered every 8 hours in one day. The primary endpoint of the study will be the within person difference in epinephrine secretion during the morning episodes of hypoglycemia on days one and two under the two treatment conditions.

Post-PharmD Fellowship in Pharmacotherapy of Inherited Metabolic Diseases
Enzyme replacement therapy for rare inherited metabolic diseases such a Pompe, Hurler’s, and Gaucher are life-extending, but expensive. Individualized titration and careful management of these biologics can ensure optimal outcomes while minimizing costs. The investigators have designed a residency for pharmacists that will provide them with the training needed to provide exceptional clinical care of patients requiring enzyme replacement therapy as well as the opportunity to develop research skills related to the pharmacotherapy of rare disorders.

Oral N-acetylcysteine for treatment of hypoglycemia associated autonomic failure
The purpose of this project is to evaluate N-acetyl cysteine (NAC) as a therapy for the prevention and treatment of hypoglycemia associated autonomic failure (HAAF) in patients with type 1 diabetes. Impaired awareness of hypoglycemia occurs in approximately 25% of adults with type 1 diabetes and is associated with a six fold higher risk of having severe hypoglycemia that requires the assistance of another to recognize and treat. HAAF is also the primary barrier to achieving the level of glucose control necessary to prevent the microvascular complications of the disease and contributes to the mortality seen in patients with T1DM. This is a single center, double blind randomized cross-over design trial that will compare the impact of N-acetylcysteine (150 mg) vs. saline infusion during experimental hypoglycemia on day one on the responses to experimental hypoglycemia on day two. Primary endpoint will be the within person difference in epinephrine secretion during the morning episodes of hypoglycemia on days one and two under the two treatment conditions. As a secondary endpoint the exposure-response relationships will be explored.

Providing Hope for People with Rare Diseases
Providing Hope for People with Rare Diseases - Rare Disease Day
For decades, Americans diagnosed with rare diseases had little hope. Drugs used to treat such conditions – known as “orphan drugs” – often never made it out of the lab as prioritization was put on drugs that would help conditions affecting millions. Then, in 1983, Congress passed the Orphan Drug Act in order to stimulate the development of new treatments for rare diseases. The move worked; since 1983 more than 350 new drugs have been developed.
Today, the University of Minnesota Center for Orphan Drug Research is investing new resources into the development of orphan drugs and drug delivery systems that could impact the lives of millions of people both in Minnesota and across the United States.
