La Jolla Pharmaceutical Company Acquires Rights to Next-Generation Gentamicin Derivatives
SAN DIEGO–(BUSINESS WIRE)–La Jolla Pharmaceutical Company (Nasdaq: LJPC) (the Company or La Jolla), a leader in the development of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases, today announced that it has entered into an exclusive option agreement to acquire the Indiana University Research and Technology Center’s (IURTC) intellectual property rights covering next-generation gentamicin derivatives. Gentamicin has become one of the most commonly prescribed hospital antibiotics, despite causing kidney toxicity. Gentamicin consists of a mixture of distinct but closely related chemical entities that may contribute differentially to the product’s toxicity profile. IURTC’s technology covers the use of next-generation, parenteral gentamicin derivatives as antimicrobial agents with the potential for reduced toxicity.
La Jolla also entered into a second option agreement with IURTC and the University of Alabama at Birmingham (UAB) for the use of these next-generation compounds for the treatment of certain rare genetic diseases, such as cystic fibrosis and Duchenne muscular dystrophy. Gentamicin’s ability to induce a lack of fidelity in gene transcription, intrinsic to its antimicrobial mechanism of action, can be leveraged in the correction of certain human genetic mutations that lead to rare genetic disorders. In spite of favorable short-term clinical proof-of-efficacy data in cystic fibrosis, development of gentamicin as a chronic treatment for these genetic diseases has been limited by its toxicity profile.
La Jolla has initially selected two lead development candidates from the technology, LJPC-30Sa and LJPC-30Sb, which are purified components of the currently marketed gentamicin product. LJPC-30Sa and LJPC-30Sb retain the biologic activity of gentamicin, yet appear to lack the traditional kidney toxicity associated with it. La Jolla plans to pursue a dual development strategy in serious bacterial infections and rare genetic disorders characterized by stop codon mutations, such as cystic fibrosis and Duchenne muscular dystrophy. Following a pre-Investigational New Drug application (IND) meeting with the U.S. Food and Drug Administration, La Jolla has received guidance that it may proceed with its proposed Phase 1 clinical trial following the submission of an IND.
“We are very pleased to gain access to this intellectual property covering next-generation gentamicin derivatives,” said George F. Tidmarsh, M.D., Ph.D., President and Chief Executive Officer of La Jolla. “The use of aminoglycoside antibiotics has been limited primarily by treatment-related toxicity. We believe that our next-generation gentamicin derivatives may retain the activity of gentamicin, but improve the therapeutic window, thereby improving the outcome for patients requiring antimicrobial agents and potentially creating new opportunities for the treatment of rare genetic disorders.”

The Company will hold an investor conference call and webcast at 8:00 AM Eastern Time/5:00 AM Pacific Time on Friday, May 8, 2015. You can participate on the call by either dialing (877) 359-9508 pin: 44727023 or click here for the webcast.
About Gentamicin and Aminoglycoside Antibiotics
Gentamicin is an FDA-approved aminoglycoside antibiotic that is commonly used in infections in pregnancy and end-stage renal disease, urinary tract infections, endocarditis, serious Staphylococcus infections, and a wide range of other infections. Aminoglycosides are a broad-spectrum class of Gram-negative antibiotics that are a mainstay in the hospital setting. They are also used to potentiate the activity of certain classes of Gram-positive antibiotics. The use of the aminoglycoside class has increased over the last 10 years due to its broad spectrum activity against resistant bacteria, concentration-dependent killing, and prolonged duration of action, but its usage has been limited by dose-dependent and cumulative kidney toxicity and ototoxicity, which is toxicity to the ear. Current prescription data for aminoglycosides as antimicrobial agents represent over a $500 million market opportunity in the U.S., adjusted for branded pricing of comparable hospital antimicrobials.
A product manufactured through fermentation, gentamicin consists of a mixture of distinct but closely related chemical entities. While these distinct chemical entities appear to all retain antimicrobial activity, they may contribute differentially to toxicity. In particular, gentamicin’s kidney toxicity appears to be associated with some but not all of its constituent chemical entities. A gentamicin derivative that retains antimicrobial activity but had reduced kidney toxicity would represent a major advance for patients.
Gentamicin’s ability to induce a lack of fidelity in gene transcription, intrinsic to its antimicrobial mechanism of action, can be leveraged in the correction of certain human genetic mutations that lead to rare genetic disorders, such as cystic fibrosis and Duchenne muscular dystrophy. In spite of favorable short-term clinical proof-of-efficacy data in cystic fibrosis, development of currently marketed gentamicin as a chronic treatment for these genetic diseases has been limited by its toxicity profile.
