From the latest update:
". Our collaboration on antimicrobials is progressing, with Genentech continuing to evaluate the leads it has received before determining, by the end of this year, whether to license or extend its option over the peptides."
The following feb article by Eric Brown, Genentech's VP for Immunology and Infectious Diseases, shows the direction Gen is heading with antibiotic research (PYC not mentioned).
PYC's candidates could end up, linked to an antibody that delivers the candidates to immune cells.

We’ve all heard about the growing threat of multi-drug resistant bacteria, or so-called “superbugs” – and it’s pretty scary. These pathogenic (disease-causing) bacteria cause serious and sometimes deadly infections and they can become resistant to even antibiotics of ‘last resort’.
One of these pathogenic bacteria is methicillin-resistant
Staphylococcus aureus or MRSA for short. MRSA can cause serious and sometimes fatal bloodstream or tissue infections, often when someone is in the hospital.
In a paper published in
Nature, Genentech scientists answer a nagging question about treating MRSA infections - namely why are these infections so hard to treat, even when the bacteria are sensitive to the antibiotics?
It’s long been suspected that a small number of MRSA hides in a compartment of our own immune cells protected from antibiotics. The bacteria then use our own immune system as a “Trojan horse” to spread the infection after the course of antibiotics is over. The
Nature paper finally proves this long-standing theory with elegant science. Importantly, the paper also describes a way to take advantage of this phenomenon to strike MRSA where it hides.
Inspired by work in oncology, the team developed a first-in-class antibody drug platform to deliver a potent antibiotic inside the human immune cell. In principle this approach could be applied to combat a variety of pathogens in addition to MRSA.
