Advanced Formulations/Drug Delivery Systems for Subcutaneous Delivery of Protein-Based Biotherapeutics. J Pharm Sci 2022; 111:2968-2982.

Abstract
Multiple advanced formulations and drug delivery systems (DDSs) have been developed to deliver protein-based biotherapeutics via the subcutaneous (SC) route. These formulations/DDSs include high-concentration solution, co-formulation of two or more proteins, large volume injection, protein cluster/complex, suspension, nanoparticle, microparticle, and hydrogel. These advanced systems provide clinical benefits related to efficacy and safety, but meanwhile, have more complicated formulations and manufacturing processes compared to conventional solution formulations. To develop a fit-for-purpose formulation/DDS for SC delivery, scientists need to consider multiple factors, such as the primary indication, targeted site, immunogenicity, compatibility, biopharmaceutics, patient compliance, etc. Next, they need to develop appropriate formulation (s) and manufacturing processes using the QbD principle and have a control strategy. This paper aims to provide a comprehensive review of advanced formulations/DDSs recently developed for SC delivery of proteins, as well as some knowledge gaps and potential strategies to narrow them through future research.

Abstract
While peptide and protein therapeutics have made tremendous advances in clinical treatments over the past few decades, they have been largely hindered by their ability to be effectively delivered to patients. While bolus parenteral injections have become standard clinical practice, they are insufficient to treat diseases that require sustained, local release of therapeutics. Cyclodextrin-based polymers (pCD) have been utilized as a platform to extend the local delivery of small-molecule hydrophobic drugs by leveraging hydrophobic-driven thermodynamic interactions between pCD and payload to extend its release, which has seen success both in vitro and in vivo. Herein, we proposed the novel synthesis of protein-polymer conjugates that are capped with a "high affinity" adamantane. Using bovine serum albumin as a model protein, and anti-interleukin 10 monoclonal antibodies as a functional example, we outline the synthesis of novel protein-polymer conjugates that, when coupled with cyclodextrin delivery platforms, can maintain a sustained release of up to 65 days without largely sacrificing protein structure/function which has significant clinical applications in local antibody-based treatments for immune diseases, cancers, and diabetes.

Abstract
A hallmark of the pancreatic hormone amylin is its high propensity toward the formation of amyloid fibrils, which makes it a challenging drug design effort. The amylin analogue pramlintide is commercially available for diabetes treatment as an adjunct to insulin therapy but requires three daily injections due to its short half-life. We report here the development of the stable, lipidated long-acting amylin analogue cagrilintide (23) and some of the structure-activity efforts that led to the selection of this analogue for clinical development with obesity as an indication. Cagrilintide is currently in clinical trial and has induced significant weight loss when dosed alone or in combination with the GLP-1 analogue semaglutide.

Gradinati V, Baruffaldi F, Abbaraju S, Laudenbach M, Amin R, Gilger B, Velagaleti P, Pravetoni M. Polymer-mediated delivery of vaccines to treat opioid use disorders and to reduce opioid-induced toxicity. Vaccine 2020; 38:4704-4712. [PMID: 32439214 DOI: 10.1016/j.vaccine.2020.05.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 05/05/2020] [Accepted: 05/09/2020] [Indexed: 11/15/2022]
Abstract
Vaccines offer a potential strategy to treat opioid use disorders (OUD) and to reduce the incidence of opioid-related overdoses. Vaccines induce opioid-specific polyclonal antibodies that selectively and effectively bind the target opioid and prevent its distribution across the blood-brain barrier. Because antibody-mediated reduction of drug distribution to the brain reduces drug-induced behavior and toxicity, vaccine efficacy depends on the quantity and quality of the antibody response. This study tested whether polymer-mediated delivery could improve vaccine efficacy against opioids as well as eliminate the need for booster injections normally required for a successful immunization. A series of novel biodegradable biocompatible thermogelling pentablock co-polymers were used to formulate a candidate vaccine against oxycodone in mice and rats. Polymer-based delivery of the anti-oxycodone vaccine was equally or more effective than administration in aluminum adjuvant in generating oxycodone-specific antibodies and in reducing oxycodone-induced effects and oxycodone distribution to the brain in mice and rats. The composition and release kinetics of the polymer formulations determined vaccine efficacy. Specifically, a formulation consisting of three simultaneous injections of the anti-oxycodone vaccine formulated in three different polymers with slow, intermediate, and fast release kinetics was more effective than an immunization regimen consisting of three sequential injections with the vaccine adsorbed on aluminum. The novel three-phased polymer vaccine formulation was effective in blocking oxycodone-induced antinociception, respiratory depression and bradycardia in rats.

A candidate drug administered subcutaneously to rodents as drug particles showing hepatic recirculation which influenced the sustained release process. Int J Pharm 2020; 581:119252.

Abstract
The aim of the present study was to evaluate and interpret the pharmacokinetic profiles after subcutaneous (s.c.) administration of crystalline AZ'72 nano- and microsuspensions to rodents. Both formulations were injected at 1.5 and 150 mg/kg to rats. For the lower dose, the profiles were similar after s.c. injection but extended as compared to oral administration. The overall exposure was higher for nanoparticles compared with microparticles during the investigated period. For the higher dose, injection of both suspensions resulted in maintained plateaus caused by the drug depots but, unexpectedly, at similar exposure levels. After addition of a further stabilizer, pluronic F127, nanosuspensions showed improved exposure with dose and higher exposure compared to larger particles in mice. Obviously, a stabilizer mixture that suits one delivery route is not necessarily optimal for another one. The differences in peak concentration (Cmax) between nano- and microparticles were mainly ascribed to differences in dissolution rate. Plasma profiles in mice showed curves with secondary absorption peaks after intravenous and oral administration, suggesting hepatic recirculation following both administration routes. This process, together with the depot formulation, complicates the analysis of absorption from s.c. administration, i.e. multiple processes were driving the plasma profile of AZ'72.

Abstract
Presented here is a novel method for encapsulating proteins into biodegradable, thermoresponsive coacervate-type polyesters. Bovine serum albumin (BSA) was efficiently incorporated into coacervate droplets via a simple thermoresponsive encapsulation mechanism. Tunable modular systems for encapsulation such as the one presented here may be useful in a range of protein delivery applications.

Abstract
PURPOSE To investigate PTSgels (Pentablock copolymers) as an injectable formulation technology for sustained ocular drug delivery. Drug release profile, tolerability, and polymer degradation for one of the thermosensitive, biodegradable, and biocompatible compositions were investigated through intracameral (IC) injection in rabbits. METHODS New Zealand White rabbit eyes were injected IC (50 μL) with 100 μg near-infrared-immunoglobulin G (NIR-IgG) in balanced salt solution (BSS) or 20% PTSgel; or with PTSgel or BSS alone. Ocular irritation scoring, intraocular pressure (IOP), and corneal thickness (CT) measurement, as well as color and infrared photography, were performed for up to 28 days postinjection. Upon euthanasia at 7, 14, or 28 days, eyes underwent ex vivo imaging (Xenogen IVIS) followed by tissue fixation and histopathology. RESULTS IC injection of PTSgel (liquid at room temperature) was performed without difficulty using a 31G needle. The polymer quickly gelled in the IC space resulting in an inferior anterior chamber deposit. The tested PTSgel was well tolerated, with no significant changes in IOP or CT. Eyes injected with NIR-IgG in PTSgel had visible NIR-IgG through 9 days postinjection, and ex vivo imaging detected a strong NIR-IgG signal in the anterior chamber through day 28. The gel deposit steadily decreased in size over time and was nearly eliminated by 28 days. CONCLUSIONS The PTSgel released IgG for 28 days and was well tolerated. The polymer degraded in parallel with drug release. These results demonstrate the potential of intracameral PTSgel formulations for sustained delivery of biologic therapies to the ocular anterior segment.
