Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Parkinson's disease (PD) is a chronic neurodegenerative disease clinically characterized by bradykinesia, hypokinesia, rigidity, resting tremor, and postural instability. These motor manifestations are attributed to the degeneration and selective loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc), leading to a dopamine (DA) deficiency in the striatum.

The environmental factors are the most common risk factor for Parkinson's disease, while hereditary determinants have minor role for disease. Furthermore, the clinical diagnosis of PD rests on the identification of characteristics related to dopamine deficiency. However, nondopaminergic and nonmotor symptoms, including cognitive dysfunction and depression, which is one of the most common and persistent symptoms, are sometimes present at an earlier disease stage and, almost inevitably, emerge with the disease progression.

Neuroinflammation is considered one of the most important factors contributing critically to pathophysiology of PD . Recently, high mobility group box-1 (HMGB1) protein has been encoded as a potential inflammatory biomarker in PD. HMGB1 mediates immune response mostly through endothelial cells and macrophage activation via targeting two vital cell receptors; Toll-like receptor 4 (TLR4) and advanced glycation end products (RAGE). HMGB1 leads to a sequential cascade of inflammatory response through enhanced release of tumor necrosis factor-alpha (TNF-α) and interleukins (ILs), prominently IL-1β and IL-6. HMGB1 mediated also up-regulation of nuclear factor kappa-β (NF-κB) with subsequent flared pro-inflammatory storm.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

control group

control group ( levo-dopa group, n =25 ) who will receive levo-dopa/carbidopa (125/12.5) mg three times daily for 6 months.

Group Type ACTIVE_COMPARATOR

carbidopa-levodopa

Intervention Type DRUG

Levodopa is typically prescribed to a patient with Parkinson disease once symptoms become more difficult to control with other anti-parkinsonism drugs. The drug can also be used for postencephalitic parkinsonism and symptomatic parkinsonism due to carbon monoxide intoxication

PTX group

(Pentoxyifylline group, n= 25) will receive levo-dopa/carbidopa (125/12.5) mg three times daily plus pentoxifylline 400 mg two times daily for 6 months.

Group Type ACTIVE_COMPARATOR

carbidopa-levodopa

Intervention Type DRUG

Levodopa is typically prescribed to a patient with Parkinson disease once symptoms become more difficult to control with other anti-parkinsonism drugs. The drug can also be used for postencephalitic parkinsonism and symptomatic parkinsonism due to carbon monoxide intoxication

Pentoxifylline 400 MG

Intervention Type DRUG

Pentoxifylline (PTX) has a well validated immune modulatory and anti-inflammatory efficacy via suppression of the TLR4/NF-κB network signaling pathway. Moreover, Pentoxifylline has a potential antioxidant capacity mostly via nuclear erythroid 2-related factor 2 (Nrf2) activation with subsequent up-regulation and expression of several antioxidant enzymes

Celecoxib group

will receive levo-dopa/carbidopa (125/12.5) mg three times daily plus celecoxib 200 mg once daily for 6 months.

Group Type ACTIVE_COMPARATOR

carbidopa-levodopa

Intervention Type DRUG

Levodopa is typically prescribed to a patient with Parkinson disease once symptoms become more difficult to control with other anti-parkinsonism drugs. The drug can also be used for postencephalitic parkinsonism and symptomatic parkinsonism due to carbon monoxide intoxication

Celecoxib 200mg

Intervention Type DRUG

Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) used to treat mild to moderate pain and help relieve symptoms of arthritis
