K0706 for Patients Diagnosed With Dementia With Lewy Bodies

A Randomized, Double Blind, Placebo-controlled Study to Evaluate the Impact of K0706 on Safety, Tolerability, Pharmacokinetics and Pharmacodynamics and Clinical Outcomes in Dementia With Lewy Bodies (DLB)

This study evaluates the safety and tolerability of treatment with K0706 in Dementia with Lewy Bodies (DLB).

The hypothesis is that K0706 will be safe and tolerable and that this drug will alter CSF and plasma biomarkers in DLB. Clinical assessments of cognitive, behavioral and motor functioning will also be evaluated. A total of 45 participants will be randomized 1:1:1 into 3 groups (n=15/per group) to be treated with sachet of 192 mg powder of K0706 ( equivalent to 96 mg capsule of K0706) or sachet of 384 mg powder of K0706 (equivalent to 192 capsule of K0706) or sachet of matching placebo ( equivalent to a capsule of placebo) for 12 weeks, followed by 4-week wash-out period.

Detailed Description

Dementia with Lewy Bodies (DLB) is an alpha-synucleinopathy and the second most common form of dementia in the elderly. DLB shares striking neuropathological and clinical similarities with both Parkinson's disease (PD) and Alzheimer's disease (AD). DLB and PD are characterized by death of dopaminergic (DA) neurons in the nigro-striatal system and formation of intra-neuronal alpha-synuclein inclusions known as Lewy bodies (LBs). Misfolded alpha-synuclein aggregates within LBs and apha-synuclein (SYN) is the highest genetic risk factor for PD and DLB followed by the microtubule associated protein tau (MAPT) . At autopsy alpha-synuclein, hyper-phosphorylated tau (p-tau) and amyloid plaques are all detected in the brains of individuals with DLB. Therefore, the neuropathology of DLB overlaps with both PD and AD, and includes alpha-synuclein accumulation in LBs, p-tau and beta-amyloid deposition . Potential cerebrospinal fluid (CSF) biomarkers, including alpha-synuclein, dopamine metabolites homovanillic acid (HVA) and 3,4-Dihydroxyphenylacetic acid (DOPAC) , total tau and p-tau and amyloid beta peptides (Abeta 40/42) may be commonly shared in AD, PD and DLB. The core clinical features of DLB, include dementia and Parkinsonism in addition to hallucinations, cognitive fluctuations and rapid eye movement (REM) sleep behavior disorders (RBD) . L-Dopa replacement therapies and acetylcholinesterase inhibitors may partially control motor and cognitive symptoms, respectively in DLB. Selective Serotonin Re-uptake Inhibitors (SSRIs) and antipsychotics manage the behavioral but worsen motor symptoms in DLB. There is a major unmet medical need for further research into DLB to identify potential therapies for this disease and provide significant insights into the treatment of other Parkinsonian and memory disorders. A major challenge facing DLB is to develop a therapy that can halt neuronal death and alleviate cognitive, motor and behavioral symptoms. No therapeutic approach exists to alter the levels of neurotoxic proteins such as alpha-synuclein and halt DA and other neuronal death in DLB. One mechanism to degrade neurotoxic proteins is autophagy , which is a process by which the cell can degrade its own contents. There is evidence that autophagy is impaired in neurodegeneration , leading to failure of degradation of protein aggregates, including misfolded alpha-synuclein. Importantly, autophagy is exploited therapeutically in several diseases, including adult chronic myeloid leukemia (CML). Tyrosine kinase inhibitors (TKIs) induce autophagy, leading to destruction of rapidly dividing tumor cells in CML and degradation of neurotoxic proteins, including alpha-synuclein, beta-amyloid and p-tau in PD and AD models. Sun Pharma Advanced Research Company Limited (SPARC Ltd.) is developing K0706, for the treatment of adult patients with chronic phase, accelerated phase, or blast phase chronic myeloid leukemia (CML) that is resistant or intolerant to prior TKI therapy or Philadelphia positive acute lymphoblastic leukemia (Ph+ ALL) that is resistant or intolerant to prior TKI therapy; and its ability to slow down progression of PD. Using allometric scaling and an average human body weight of 70kg an oral dose of 15-30mg/kg once daily in mice corresponds to an oral human equivalent dose (HED) of 85-160 mg which is within the tolerated dose in both CML and PD. Therefore, the effects of a sachet of 192 mg powder of K0706 (equivalent to 96 mg capsule of K0706 ) and a sachet of 384 mg powder of K0706( equivalet to 192 mg capsule of K0706) and a sachet of matching placebo taken daily by mouth for 12 weeks, followed by a 4 week wash-out period will be evaluated in individuals diagnosed with DLB. The data obtained from this study will serve as a proof of concept for future placebo-controlled, double-blind studies in patients diagnosed with DLB, AD, or PD.

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Measurement of the effects of K0706 on Cognition using the Montreal Cognitive Assessment (MoCA)	The MoCA is designed as a rapid screening instrument for mild cognitive dysfunction. It assesses different cognitive domains, including attention and concentration, executive functions, memory, language, visuo-constructional skills, conceptual thinking, calculations and orientation. Scores range between 0 and 30 where 30 is the highest score and 0 is the lowest score.	12 weeks
Measurement of the effects of K0706 on Cognition using the Trail Making Test (TMT)	The Trail Making Test (TMT) is a neuropsychological test of visual attention and task switching. It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. The test can provide information about visual search speed, scanning, speed of processing, mental flexibility, as well as executive functioning. The time to complete the test is measured.	12 weeks
Measuring the effects of K0706 on Cognition using the Alzheimer's Disease Assessment Scale - cognitive (ADAS-cog).	ADAS-cog aims to evaluate cognitive impairment in Alzheimer's disease. ADAS-cog was included in this LBD study to better capture potential changes in activities of daily living (ADL) and non-ADLs and severity of cognitive impairment. Points for errors in each task are added up and the greater the dysfunction, the greater the score.	12 weeks
Measuring the effects of K0706 on Behavior using the Alzheimer's disease Cooperative Study-Activity of Daily Living scale.	ADCS-ADL is an activity of daily living inventory to assess functional performance. Using a structured interview format, study partners are queried as to whether participants attempted each item in the inventory during the prior 4 weeks and their level of performance. The ADCS-ADL includes some items from traditional basic ADL tests as well as instrumental (complex) activities of daily living. It is a 23 item scale that provide a total score from 0-78 with a lower score indicating greater severity.	12 weeks
Measuring the effects of K0706 on Behavior using the Neuropsychiatric Inventory (NPI)	The NPI is a multi-item instrument to assess psychopathology in Azheimer's disease based on interview with the study partner. The NPI evaluates both the frequency and severity of 10 neuropsychiatric disturbances. Frequency assessments range from 1 (occasionally, less than once per week) to 4 (very frequently, once or more per day or continuously) as well as severity (1=mild, 2=moderate, 3=severe). The overall score and the score for each subscale are the product of severity and frequency.	12 weeks
Measuring the effects of K0706 on Behavior using the Clinical Assessment of Fluctuation (CAF)	The CAF consists of seven items of confusional behavior (falls, fluctuation, drowsiness, attention, disorganized thinking, altered level of consciousness, communication), scores for which are summed to provide a severity score for fluctuating confusion ranging from 0 to 21.	12 weeks
Measuring the effects of K0706 on Behavior using the Irritability-Apathy Scale (IAS)	The IAS measures apathy and irritability in patients with dementia. The IAS is a 28-item self-administered questionnaire collecting information about different aspects of irritability and apathy utilizing a 0-3 scale for each item to indicate severity. Both a patient and a study partner version can be administered. The IAS will be completed separately by Subjects and Study Partners. A higher total score indicates higher severity.	12 weeks
Measuring the effects of K0706 on Behavior using the Problem Behaviors Assessment short form (PBA-s)	PBA-s is a structured interview in which a trained interviewer rates the frequency and severity of neuropsychiatric symptoms through observation and the reporting of the Subject and Study Partner. Symptoms rated include depressed mood, suicidal ideation, anxiety, irritability, angry or aggressive behavior, apathy, perseverative thinking or behavior, obsessive-compulsive behaviors, delusional or paranoid thinking, hallucinations, and disoriented behavior. Each behavioral problem is rated for both severity and frequency on a 0-4- point scale; severity and frequency ratings are then multiplied to provide an overall score for each symptom.	12 weeks
Measuring the effects of K0706 on Motor Function by using the Unified Parkinson's Disease Rating Scale (UPDRS)-I-III.	UPDRS-I-III is used to follow the longitudinal course of Parkinson's disease. The UPDRS is made up of these sections: Part I: evaluation of mentation, behavior, and mood. Part II: self-evaluation of the activities of daily life (ADLs) Part III: clinician-scored monitored motor evaluation. Part IV: complications of therapy. Part V: Hoehn and Yahr staging of severity of Parkinson's disease. Part VI: Schwab and England ADL scale.	12 weeks
Measuring the effects of K0706 on Motor Function by using the Timed-Up-And-Go (TUG).	Timed Up and Go (TUG) is an assessment of mobility, balance, walking ability, and fall risk. It measures the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down.	12 weeks
