Background: Cerebral palsy (CP) is a brain disorder that affects the development of movement and posture leading to limitation of Range of Movement (ROM) in the growing children. CP leads to deformities as equinus foot deformity. We aim to investigate the efficacy of different botulinum toxin (BTX) products with or without serial casting in reducing the muscle spasticity in equinus foot deformity in patients with CP. Methods: A systematic review of the literature was performed via searching of the different electronic databases. The following databases were used PubMed, Scopus, Web of Science (WOS), and GHL. We analyzed the extracted data by network meta-analysis method using R software package (version 3.5.0). Results: Regarding Modified Ashworth score (MAS), BTX-A was superior compared to placebo and BTX-A plus immediate casting (MD = −0.39, 95% CI [−0.60; −0.18]) and (MD = −0.50, 95% CI [−0.98; −0.02]) respectively. Concerning growth motor function movement Classification System (GMFM), Neuronox ranked above at 3 months (MD = −1.60, 95% CI [−2.87; −0.33]) and at six months (MD = −1.90, 95% CI [−3.48; −0.32]) compared to BTX-A. Regarding the Modified Tardieu scale (MTS) with knee flexion, BTX-A was superior to BTX-A plus immediate casting (MD = 8.60, 95% CI [1.76; 15.44]). Concerning passive range of movement (PROM) with Knee flexion or extension at 3 months, BTX-A showed a significant improvement compared to BTX-A plus immediate casting. Conclusion: BTX-A ranked best on physician rating scale (PRS), MAS, MTS with knee flexion and PROM (Knee flexion and extension) compared to Neuronox and Botulax. BTX-A alone was also better than BTX-A plus immediate casting.

Biosimilars are biological products that efficiently replicate the function of the originator products. They have changed the prognosis of millions of patients with many serious conditions. The main engine beyond their development is to bring competition into the marketplace, accordingly further the healthcare systems’ sustainability. Furthermore, by lowering financial obstacles to biological treatments, biosimilars play a critical role in budgetary redistribution and, hence, promote better allocation of scarce healthcare resources. Today, biosimilars have become a substantial component of effective biological therapies anywhere in the world. Alike, most Middle East and African countries are encouraging the domestic biosimilars industry, and the whole region is aware of the biosimilars’ importance. However, constraints to increasing biosimilars uptake should be addressed.
