Sugammadex (brand name Bridion) is marketed by Merck Sharp and Dohme, and was approved by the United States FDA on December 15, 2015.

Sugammadex sodium was first approved by European Medicine Agency (EMA) on July 25, 2008, then approved by Pharmaceuticals and Medical Devices Agency of Japan (PMDA) on Jan 20, 2010, and approved by the US. food and drug administration (FDA) on Dec 15, 2015. It was developed and marketed as Bridion® by Merck Sharp & Dohme.

Sugammadex is reversal of neuromuscular blockade without relying on inhibition of acetylcholinesterase. It is the first selective relaxant binding agent (SRBA). It is indicated in neuromuscular blockade induced by rocuronium or vecuronium in adults.

Bridion® is available as injection solution for intravenous use, containing 100 mg /mL of free Sugammadex. The recommended dose is 4 mg/kg for adults if recovery has reached at least 1-2 post-tetanic counts (PTC) following rocuronium or vecuronium induced blockade.

Sugammadex (Org 25969, tradename Bridion) is an agent for reversal of neuromuscular blockade by the agent rocuronium in general anaesthesia. It is the first selective relaxant binding agent (SRBA).

Sugammadex.png

Sugammadex Sodium is the sodium salt form of the biologically inert, selective relaxant binding agent (SRBA) sugammadex, a modified, anionic gamma cyclodextrinderivative containing a hydrophilic exterior and a hydrophobic core, with neuromuscular blocking drug (NMBD) reversal activity. Upon administration, the negatively charged carboxyl-thio-ether groups of sugammadex selectively and reversibly bind to the positively charged quaternary nitrogen of a steroidal NMBD, which was administered at an earlier time for anesthetic purposes. The encapsulation of the NMBD by sugammadex blocks its ability to bind to nicotinic receptors in the neuromuscular junction and thereby reverses the NMBD-induced neuromuscular blockade. Sugammadex binds rocuronium, vecuronium, and to a lesser extent pancuronium.

 Sugammadex is a selective relaxant binding agent indicated for reversal of neuromuscular blockade induced by rocuronium bromide and vecuronium bromide during surgery in adults. Rocuronium bromide and vecuronium bromide are neuromuscular blocking medications that cause temporary paralysis and are especially useful for general anesthesia, ventilation, or tracheal intubation that patients may require for surgery. Sugammadex provides a new treatment option to reverse the effects of those medications and possibly help patients recover sooner post-surgery. Sugammadex (brand name Bridion) is marketed by Merck Sharp and Dohme, and was approved by the United States FDA on December 15, 2015.

Sugammadex is used to reverse neuromuscular blockade after administration of non-depolarizing neuromuscular-blocking agentssuch as vecuronium or rocuronium.

Pharmacology

Pharmacodynamics

Sugammadex is a modified γ-cyclodextrin, with a lipophilic core and a hydrophilic periphery. This gamma cyclodextrin has been modified from its natural state by placing eight carboxyl thio ether groups at the sixth carbon positions. These extensions extend the cavity size allowing greater encapsulation of the rocuronium molecule. These negatively charged extensions electrostatically bind to the quaternary nitrogen of the target as well as contribute to the aqueous nature of the cyclodextrin. Sugammadex’s binding encapsulation of rocuronium is one of the strongest among cyclodextrins and their guest molecules. The rocuronium molecule (a modified steroid) bound within sugammadex’s lipophilic core, is rendered unavailable to bind to the acetylcholine receptor at the neuromuscular junction.

Right: Space-filling model of a sugammadex sodium molecule in the same orientation.

Sugammadex, unlike neostigmine, does not inhibit acetylcholinesterase so cholinergic effects are not produced and co-administration of an antimuscarinicagent (glycopyrronium bromide or atropine) is not needed. Sugammadex might therefore be expected to have fewer adverse effects than the traditional reversal agents.

When muscle relaxant with rapid onset and short duration of action is required, there has been little choice apart from suxamethonium but this drug has important contraindications; for example, it can trigger malignant hyperthermia in susceptible individuals, it has a prolonged duration of action in patients with pseudocholinesterase deficiency and it causes an increase in plasma potassium concentration which is dangerous in some circumstances. Rocuronium has a comparably quick onset in high dose (0.6 mg kg−1 to 1 mg kg−1) and can be rapidly reversed with sugammadex (16 mg kg−1), so this drug combination offers an alternative to suxamethonium.

‘Recurarisation’, a phenomenon of recurrence of neuromuscular block, may occur where the reversal agents wear off before a neuromuscular blocking drug is completely cleared. This is very unusual with all but the longest acting neuromuscular blocking drugs (such as gallamine, pancuronium or tubocurarine). It has been demonstrated to occur only rarely with sugammadex, and only when insufficient doses were administered.[1] The underlying mechanism is thought to be related to redistribution of relaxant after reversal. It may occur for a limited range of sugammadex doses which are sufficient for complex formation with relaxant in the central compartment, but insufficient for additional relaxant returning to central from peripheral compartments.[2]

Sugammadex has been shown to have affinity for two other aminosteroid neuromuscular blocking agents, vecuronium and pancuronium. Although sugammadex has a lower affinity for vecuronium than for rocuronium, reversal of vecuronium is still effective because fewer vecuronium molecules are present in vivo for equivalent blockade: vecuronium is approximately seven times more potent than rocuronium. Sugammadex encapsulates with a 1:1 ratio and therefore will adequately reverse vecuronium as there are fewer molecules to bind compared to rocuronium.[3] Shallow pancuronium blockade has been successfully reversed by sugammadex in phase III clinical trials.[4]

Efficacy

A study was carried out in Europe looking at its suitability in rapid sequence induction. It found that sugammadex provides a rapid and dose-dependent reversal of neuromuscular blockade induced by high-dose rocuronium.[5]

A Cochrane review on sugammadex concluded that “sugammadex was shown to be more effective than placebo (no medication) or neostigmine in reversing muscle relaxation caused by neuromuscular blockade during surgery and is relatively safe. Serious complications occurred in less than 1% of the patients who received sugammadex. The results of this review article (especially the safety results) need to be confirmed by future trials on larger patient populations”.[6]

Tolerability

Sugammadex was generally well tolerated in clinical trials in surgical patients or healthy volunteers. In pooled analyses, the tolerability profile of sugammadex was generally similar to that of placebo or neostigmine plus glycopyrrolate.[7]

History

Sugammadex was discovered by the pharmaceutical company Organon at the Newhouse Research Site in Scotland.[8] Organon was acquired by Schering-Plough in 2007; Schering-Plough merged with Merck in 2009. Sugammadex is now owned and sold by Merck.

The US Food and Drug Administration (FDA) initially rejected Schering-Plough’s New Drug Application for sugammadex in 2008,[9] but finally approved the medication for use in the United States on December 15, 2015.[10] Sugammadex was approved for use in the European Union on July 29, 2008.[11]

SYNTHESIS

Sugammadex (Trade name: Bridion) is first disclosed in US6670340 assigned to Akzo Nobel. Sugammadex sodium was approved in EMEA as an agent for reversal of neuromuscular blockade by the agent rocuronium in general anaesthesia in 2008 and is the first selective relaxant binding agent (SRBA).

Figure imgf000002_0001

Sugammadex sodium contains 8 recurring glucose units each with 5 asymmetric carbon atoms, in total 40 asymmetric carbon atoms for the whole molecule. Sugammadex is a modified γ-cyclodextrin, with a lipophilic core and a hydrophilic periphery. The gamma cyclodextrin has been modified from its natural state by placing eight carboxyl thio ether groups at the sixth carbon positions.

The US Patent 6670340 assigned to Akzo Nobel discloses a process for preparing Sugammadex sodium as depicted in Scheme-I:

Scheme-I

Figure imgf000003_0001

Sugammadex Sodium The first step in the process in the scheme-I involves the preparation of Vilsmeier Hack reagent by the reaction , of DMF, triphenylphosphine and Iodine. The triphenylphosphine oxide is formed as a byproduct of the first step. Removal of triphenylphosphine oxide from the product is very difficult from the reaction mass as it requires repeated washing with DMF under argon atmosphere, which leads to inconsistency in yield of final product Sugammadex. The second step involves the reaction of 6-perdeoxy-6-per-Iodo-Gamma cyclodextrin with 3-mercapto propionic acid in presence of alkali metal hydrides in an organic solvent to give 6-per-deoxy-6-per-(2-carboxyethyl)thio-y- cyclodextrin sodium salt.

The PCT publication WO2012/025937 discloses preparation of Sugammadex involving the reaction of gamma cyclodextrin with phosphorous halide in presence of organic solvent, thereby overcomes the formation of triphenyl phosphine oxide. The publication also discloses the use of 6-per deoxy-6-per- chloro-y-cyclodextrin in the preparation of the Sugammadex.

The purification techniques in the prior arts employ column chromatographic / membrane dialysis techniques which are costly and not convenient in large scale operations.

Figure imgf000002_0001

Sugammadex (designation Org 25969, trade name Bridion) is an agent for reversal of neuromuscular blockade by the agent rocuronium in general anaesthesia. It is the first selective relaxant binding agent (SRBA). This gamma cyclodextrin has been modified from its natural state by placing eight carboxyl thio ether groups at the sixth earbon positions. These extensions extend the cavity size allowing greater encapsulation of the rocuronium molecule. These negatively charged extensions electrostatically bind to the positively charged ammonium group as well as contribute to the aqueous nature of the cyclodextrin. Sugammadex’s binding encapsulation of rocuronium is one of the strongest among cyclodextrins and their guest molecules. The rocuronium molecule (a modified steroid) bound within Sugammadex’s lipophilic core, is rendered unavailable to bind to the acetylcholine receptor at the neuromuscular junction. Sugammadex sodium contains 8 recurring glucose units each with 5 asymmetric carbon atoms, in total 40 asymmetric carbon atoms for the whole molecule.

The Sugammadex was disclosed in US6670340 by Akzo Nobel. The process for preparing Sugammadex is there outlined as follows: (Scheme-I)

Scheme – 1 Suggamadex

above process step-1 involves the preparation of Vilsmeier Hack reagent by the reaction of DMF, triphenylphosphine and Iodine. Drawback associated with this step is formation of triphenylphosphine oxide as a byproduct. Removal of triphenylphosphine oxide is very difficult from the reaction; it requires repeated washing with DMF under argon atmosphere and leads to inconsistency in yield of final product. Due to this, process is lengthy and not feasible on commercial scale.

Scheme – IV

[0018] The alkali metal hydrides are selected from the group consisting of sodium hydride, lithium hydride, potassium hydride preferably sodium hydride. [0019] The advantage of the present process is there that there is no formation of by product such as triphenylphosphine oxide, as present in prior art process. So, purification is not required which leads to better purity and yields for the intermediate as well as for final product.

[0020] Another advantage of the present invention is the significant difference between molecular weight of 6-per deoxy-6-per-chloro-y-cyclodextrin (Mol. wt. 1444) and the final product (Mol. wt. 2178). The use of 6-per deoxy-6-per- chforo-y-cyclodextrin instead of 6-per deoxy-6-per-bromo-y-cyclodextrin (Mol. wt. 1800) in the final stage of the process would extend the scope of selection of appropriate dialysis membranes with precise molecular weight cut off and there by facilitate efficient purification of Sugammadex. The invention is further illustrated with following non-limiting examples:

Example: 1 Preparation of 6-perdeoxy-6-per-bromo Gamma Cyclodextrin

[0021] A portion of phosphorous pentachloride (256.5 g) was added in DMF (300 ml) at 0-5°C. Mixture was stirred at 20-25°C for lhr. A solution of gamma- cyclodextrin (50 g) in DMF (400ml) was added to above solution at 5-10°C under nitrogen. Mixture was stirred at 65 -70°C 14 hrs. The reaction mixture was cooled to 20 – 25°C and DMF was removed under vacuum. The viscous residue was diluted with water. 5M NaOH solution was added dropwise to the above solution at 5-10°C until PH=8, the resulting slurry was stirred for one hour at 20-25°C. The slurry was filtered under vacuum and washed with water and dried. The crude product was diluted with water and resulting slurry was stirred at 20-25uC for one hour. The slurry was filtered under vacuum and the solid dried at 55- 60°C under vacuum for 12hrs. (Yield – 94 – 98%, purity-98.5% by HPLC) Example: 2 Preparation of Sugammadax

[0022] To a mixture of sodium hydride (24.4 g) in DMF (150 ml) at 0-5°C, a solution of 3-mercapto propionic acid (23.7 ml, 10 eq) in DMF (50 ml) was added slowly under argon maintaining the temperature below 10 C. The resulting mixture was stirred at 20 -25°C for 30 mins. Then 6-deoxy-6-chloro gamma cyclodextrin (40 g) in DMF (400 ml) was added slowly at 5-10°C under argon and the resulting mixture was heated to 70-75°C for 12 hrs. Reaction mixture was cooled to 20 -25°C and DMF removed partially under vacuum and the reaction mixture is diluted with ethanol (600 ml). The resulting precipitate was stirred at 20 – 25°C for 1 hr and filtered under vacuum and the solid dried to afford the crude Sugammadex (wet) (100 g). The crude product was purified over silica gel and sephadex G-25 column using water as eluent. (Yield 60%)

    EXAMPLES Example: 1 Preparation of 6-perdeoxy-6-per-chloro Gamma Cyclodextrin

    256.8 g (0.62 Moles) of Phosphorous pentachloride was added to 400 ml of Dimethyformamide (DMF) at 25-30 °C and mixture was maintained for 1 hour at the same temperature. 100 g (0.04 Moles) of Gamma-cyclodextrin was gradually added to the reaction mixture at 25-30 °C under nitrogen. The temperature of the reaction mixture was raised to 65 -70 °C and maintained at the same temperature for 14 to 16 hrs. The reaction mixture was then slowly added to chilled water at 0- 15 °C. The pH of the reaction mass was adjusted to 7-8 with 30% solution of sodium hydroxide in water. The contents were stirred at 25-30 °C at 2 hours. The resultant solid was filtered and washed with water (200 ml). The wet solid was repeatedly washed with purified water at 25-30 °C and dried at 65-70 °C till the moisture level was reduced to less than 4.0%. The yield of the obtained product was 90% Example: 2 Preparation of Sugammadex sodium

    To a mixture of 1 10.2 g, (15 equ.) 3-mercapto propionic acid and 800 ml Dimethyl formamide (DMF) , a 30% solution of sodium methoxide (373.9 g, 30 equ) in methanol was added at 20-25°C and stirred for 1 hour at the same temperature. The compound from example- 1 (100 g) was added to the reaction mixture at 25-30°Cand heated to 75-80°C and maintained at the 75-80°C for 12 to 14 hours. After completion of the reaction, the reaction mass was cooled to 20- 25°C, then methanol (1000 ml) was added to the reaction mass and stirred for 2 hours at the same temperature. The resultant solid was filtered, washed with methanol (200 ml) and dried for 60-65°C for 8 hrs.

    The crude product was dissolved in water (294 ml) and methanol (294 ml), treated with activated carbon (39.2 g, 20 % w/w) and was filtered through celite, washed the carbon cake with purified water (98 ml). The filtrate was heated to 50-55°C and slowly methanol (2646 ml) was added at the same temperature. The contents were cooled to 20 to 25°C and stirred for 2 hours at the same temperature. The resulted solid was washed with methanol (200 ml) and dried under vacuum at 60-65°C for 14 hours. The obtained product had yield of 70.34% and HPLC purity of 99.43 %.

    Example-3

    The Sugammadex prepared from example-2 was, dissolved in water ( 150 ml) and methanol (1 50 ml), treated with activated carbon (20 g) and filtered the carbon cake through celite bed and the carbon cake was washed with purified water (50 mL). The filtrate was heated to 50-55°C and added methanol (1350 ml) at the same temperature. The contents were cooled to 20 to 25°C and stirred for 2 hours at the same temperature. The resultant solid was washed with methanol (200 ml) and dried in vacuum at 70 – 75°C for 24 hrs. The obtained yield was 63%.

Chemical formula is C 72 H 104 Na 8 O 48 S 8. “Su” stands for sugar and “gammadex” stands for structural molecule gamma-cyclodextrin. [1] Cyclodextrins are cyclic dextrose units joined through 1-4 glycosyl bonds that are produced from starch or starch derivates using cyclodextrin glycosyltransferase. The three natural unmodified cyclodextrins are α-, β-or γ-cyclodextrin. Compared with α-and β-cyclodextrins, γ-cyclodextrin exhibits more favorable properties in terms of the size of its internal cavity, water solubility and bioavailability. To have a better fit of the larger rigid structure of the aminosteroid muscle relaxant molecule (e.g., rocuronium or vecuronium) within the cavity of γ-cyclodextrin, the latter was modified by adding eight side chains to extend the cavity. This modification allowed the four hydrophobic steroidal rings of rocuronium to be better accommodated within the hydrophobic cavity. In addition, adding negatively charged carboxyl groups at the end of the eight side chains served two purposes. First, the repellent forces of the negative charges keep propionic acid side chains from being disordered, thereby allowing the cavity to remain open and maintain structural integrity. Second, adding these negatively charged carboxyl groups enhances electrostatic binding to the positively charged quaternary nitrogen of rocuronium [Figure 1]. Three-dimensional structure resembles a hollow, truncated cone or a doughnut. [9]

    Sugammadex (Bridion®)
    Schering-Plough’s sugammadex sodium, the first selective relaxant binding agent (SRBA), was approved last year
    in the European Union. Sugammadex is a drug-specific cyclodextrin designed specifically to reverse the effects of the muscle relaxant rocuronium bromide (Esmeron®/Zemuron®) when used as a component of general anesthesia during surgical procedures. Unlike other reversal agents, sugammadex can achieve reversal following rocuronium bromide administration within three minutes, regardless of the depth of block. Schering-Plough, which acquired the product via its acquisition of Organon BioSciences in late 2007, began marketing sugammadex in Sweden in September, 2008.
    There are several reports on the syntheses of sugammadex, all following a similar three-step procedure [72-74]. Bromination of 􀀁-cyclodexdrin 127 with the Vilsmeier-Haack reagent prepared by reaction of bromine with triphenylphospine in DMF gave the per-6-bromo-􀀁-cyclodextrin 128 in 95-98% yield [73]. Nucleophilic displacement of the bromines of 128 with methyl 3-mercaptopropionate (129) and cesium carbonate at 50 °C in DMF gave 6-perdeoxy-6-per(2-methoxycarbonylethyl) thio-􀀁-cyclodextrin 130 as a white powder.
    Saponification of the esters of 130 was accomplished by reaction with aqueous sodium hydroxide solution to provide
    sugammadex (XVII) as a glassy solid in 52% yield for the 2 steps [72,74].
