Peptilogics | January 11, 2022
Peptilogics, a biotech company that engineers peptide therapeutics to radically improve the treatment landscape for patients with life-threatening diseases, announced that the U.S. Food and Drug Administration as accepted the company's Investigational New Drug Application for PLG0206 to treat periprosthetic joint infection allowing the Phase 1b study to proceed.
Peptilogics will evaluate the safety and efficacy of PLG0206 in a Phase 1b open-label, dose-escalating study in patients undergoing debridement, antibiotics and implant retention surgery for the treatment of PJI occurring after total knee arthroplasty.
“PJI is a devastating condition with limited treatment options, since systemic antibiotics frequently fail to eliminate the infection and surgery to remove the infected hardware is then required. Based on our promising preclinical efficacy and healthy volunteer Phase 1 study data with PLG0206, we are excited to explore its safety and efficacy as a potential treatment for patients with PJI.”
Jonathan Steckbeck, Ph.D., Founder and CEO of Peptilogics
PLG0206 is an investigational broad-spectrum, anti-biofilm, anti-infective peptide therapeutic. The current standard of care for PJI includes numerous high-risk surgical procedures coupled with systemic antibiotic treatment, which are often ineffective due to device-associated biofilms. PLG0206 was designed with a unique mechanism of action that allows it to directly addresses biofilm bacteria and persistent pathogens that evade standard of care antibiotics by targeting and disrupting bacterial membranes to trigger bacterial cell death. PLG0206 has demonstrated best-in-class, rapidly bactericidal, broad-spectrum activity against a variety of pathogens, regardless of resistance phenotype, identified by the World Health Organization and the Centers for Disease Control as critical, urgent or high priority targets. PLG0206 has previously been granted FDA Orphan Drug Designation for the treatment of PJI and has been designated as a Qualified Infectious Disease Product (QIDP) as well.
In December, Peptilogics announced the publication of two peer-reviewed studies on PLG0206. Data from a first-in-human Phase 1 study of PLG0206, published in Antimicrobial Agents and Chemotherapy, showed the investigational therapeutic was safe and well tolerated and has favorable pharmacokinetics when intravenously administered as a single dose. These data were presented in September at ID Week. Data from a clinical proxy study of PLG0206, published in Microbiology Spectrum, showed the investigational therapeutics’ ability to reduce bacteria on chronically infected prosthetic knee joints, which may translate to improved clinical outcomes.
About Periprosthetic Joint Infection (PJI)
More than one million total joint replacements are performed annually in the U.S., a number that is expected to grow to four million annual procedures by 2030 due to an aging and active population. Following joint replacement, 1-2% of patients will develop a PJI, a serious life-threatening condition which often necessitates continuous antibiotic usage and high-risk surgical procedures with limited ability to resolve the infection. The current standard of care has up to a 60% failure rate and results in a substantial number of patient deaths, evidenced by a 25% five-year mortality rate.
Peptilogics engineers peptide therapeutics to radically improve the treatment landscape for patients with life-threatening diseases. Through biological and pharmaceutical expertise, novel artificial intelligence algorithms, and purpose-built super-computing, Peptilogics is developing an extensive therapeutic pipeline and accelerating discovery efforts at a pace and scale that was previously impossible. Peptilogics is backed by visionary investors in life science and technology including Peter Thiel, Presight Capital, CARB-X, and Founders Fund.
CELL AND GENE THERAPY
Vipergen | February 18, 2021
Vipergen ApS announced today a published study depicting a ground-breaking new medication revelation approach that empowers, interestingly, screening DNA-encoded small-molecule libraries (DELs) inside living cells. The study, published in the peer-reviewed Journal of the American Chemical Society, highlights the potential of Vipergen's Cellular Binder Trap Enrichment® (cBTE) technology to significantly grow the ability to discover novel small molecules, including against difficult-to-drug targets, and reduce attrition rates in drug discovery. Vipergen is offering its cBTE DNA-encoded library drug disclosure platform as a service to biotechnology and pharmaceutical company partners to accelerate and improve their drug discovery processes.
"This research validates the potential for Vipergen's Cellular Binder Trap Enrichment platform to become a revolutionary tool in small-molecule drug discovery based on its ability to successfully screen DELs against drug targets inside living cells, with no requirement for purified active target protein," said Nils Hansen, Ph.D., Chief Executive Officer of Vipergen. "We expect the ability to perform DEL screening under the more physiologically relevant conditions of a living cell to significantly lower attrition rates in drug discovery. Furthermore, by uniquely allowing us to eliminate the requirement for highly purified active target protein, this technology will improve timelines and bring about new options for novel drug development by allowing us to screen many more targets, prioritize those giving the most promising screening results, and screen DELs against challenging targets that are difficult to express and purify in an active form. We look forward to providing this new tool to biotechnology and pharmaceutical partners to substantially improve the efficiency and success of their small-molecule drug discovery efforts."

Vipergen ApS, Anavo Therapeutics | May 18, 2021
Vipergen, a leading supplier of small-molecule drug discovery services focused on DNA-encoded library (DEL) technologies, has signed a drug discovery service agreement with Anavo Therapeutics. Vipergen will use its patented high-fidelity DNA-encoded library (DEL) technology platforms to provide novel small-molecule drug leads against selected Anavo discovery targets, according to the terms of the agreement. The agreement's financial terms were not disclosed.
"Vipergen's novel solutions to DNA-encoded libraries are useful components for ramping up our patented drug development activities against a chosen portfolio of innovative goals," said Anavo CEO Birgit Zech, Ph.D. "We are excited to collaborate with Vipergen to kick-start Anavo's proprietary drug development activities as we strive to create a comprehensive and secure platform for phosphatase drug discovery against all valuable targets in the space."
"We are delighted to have been chosen by Anavo, a new company focusing on understanding the full therapeutic potential of human phosphatase biology in the development of new cancer therapies," said Nils Hansen, Ph.D., Chief Executive Officer of Vipergen. "Phosphatases are a rich target space that has been thought to be impenetrable for decades. We are excited to use our DNA-encoded library technology to quickly produce high-quality hits and leads as part of Anavo's comprehensive approach to finding and improving small-molecule phosphatase activity modulators."
