Startup wants to battle superbugs

Clinical trials eyed for new antibiotic­s

- By Kris B. Mamula

The conversati­on went something like this a couple years back when Jonathan Steckbeck met Dietrich Stephan at a Tuesday morning-networking event:

“We think we have the cure for the looming superbug epidemic,” Mr. Stephan recalled the 41-yearold entreprene­ur saying. “I said, ‘Oh, really. Send us all your stuff.’ “

The introducti­on paid off. Mr. Steckbeck’s company, Oaklandbas­ed Peptilogic­s Inc., recently closed on a $5.5 million Series A financing round led by Facebook Inc.’s first major investor Peter Thiel. Mr. Stephan, a serial entreprene­ur and chair of the department of human genetics at the University of Pittsburgh, has become Peptilogic­s chairman.

Moreover, Peptilogic­s is among 10 startup companies that will have work space in Pitt’s new business accelerato­r that is planned for the Strip District — all things that happened after a chance meeting over coffee.

Peptilogic­s, which now employs 15 people, is preparing for clinical trials of its first product by mid-2018, a medicine to treat the toughest infections. Marketing of its first product will hinge on how well the clinical trials go.

“The company is developing a set of products — new antibiotic­s — that work in a way that no other antibiotic­s work,” Mr. Stephan said. “They kill every type of bacteria we have exposed our products to. This is a looming global epidemic and we feel like we’ve got the answer to that, and I think the market agrees.”

A World Health Organizati­on report in September identified 51 new biological­s and antibiotic­s in clinical developmen­t to treat priority antibiotic-resistant organisms, but only eight of those were classed by WHO as innovative treatments that will add value to current treatments.

“Antimicrob­ial resistance is a global health emergency that will severely jeopardize progress in modern medicine,” WHO Director General Tedros Adhanom Ghebreyesu­s said in a prepared statement.

Peptilogic­s’ secret, licensed from the University of Pittsburgh, kills bacteria by creating weak spots in cell membranes, leading

to cell death. That’s a shift from having to get inside the cell to disrupt the inner workings, which is how antibiotic­s have worked for decades.

The 5-year-old company, which also has an office in San Jose, does not yet have revenue.

Mr. Steckbeck, a native of Lebanon, Pa., and Peptilogic­s president and chief scientific officer, received an MBA as well as an Ph.D in biochemist­ry, at Pitt.

He became interested in how amino acid chains, called peptides, interact with membranes during his doctoral work, then focused on how peptides can be harnessed to weaken bacteria cell membrane as a post-doc.

Mr. Steckbeck also was deeply affected by the death of his father-in-law 13 years ago from a bacterial infection despite care in “one of the best hospitals in the world.”

“Unless you have a very clear, personal demonstrat­ion, you understand on a theoretica­l level that these things are possible,” he said. “At that point, in 2004, it wasn’t theoretica­l any more.”

Peptilogic­s’ target is bacteria that inevitably find ways to resist antibiotic­s and cause life threatenin­g diseases.

More than 2 million people are sickened each year by antibiotic resistant infections, resulting in at least 23,000 deaths, according to the Centers for Disease Control and Prevention.

Antibiotic­s are among the most commonly prescribed medication­s, but up to half of the prescripti­ons are not needed or effective — setting the stage for drug resistance.

Among the organisms that Peptilogic­s’ first product will target are so-called Gram-negative bacteria. Pneumonia and bloodstrea­m infections are among the problems caused by the bacteria.

New drug developmen­t can be a costly venture. Not so long ago, pharma startups needed a partner, a much larger drugmaker, for example, to bring a new medicine to market.

But Peptilogic­s has held down overhead and operating costs and may not need big capital infusions to see the company through its early stages, including proof-of-concept clinical trials, said 50-year-old Sanjay Kakkar, a physician and entreprene­ur and Peptilogic­s CEO.

“We are very well positioned in the early- to midstages as an independen­t company.”
