The Safety, Tolerability, and Pharmacokinetics of ALT-BB4 (A Novel Recombinant Hyaluronidase): A Randomized, Double-Blinded, Placebo-Controlled, Phase 1 Study in Healthy Volunteers.

ABSTRACT:

Introduction

Hyaluronidase has been used as an adjuvant to facilitate subcutaneous drug delivery by degrading hyaluronic acid, a viscoelastic barrier in subcutaneous tissue. However, traditional animal-derived hyaluronidases raise safety concerns, including risk of anaphylaxis and zoonoses. This study aimed to evaluate the safety, tolerability, and pharmacokinetics of ALT-BB4, a novel recombinant hyaluronidase derived from human hyaluronidase PH20, in healthy adults.

Methods

This first-in-human, multicenter, randomized, double-blinded, placebo-controlled phase 1 study included 244 participants who received single intradermal or subcutaneous injections of ALT-BB4 or placebo. The study was conducted in three parts: part I assessed drug allergy reactions, part II-A evaluated ph
