Progress Report: New Antibacterials In the Fight against MDR Bacteria

Since the beginning of this millennium we have seen antibiotic R&D dwindle year after year.

Most Anti-Infective Guidelines Don’t Get No Respect (Let Alone Use!)

It is no secret that most existing antibiotic guidelines are not getting much use these days.  The only indications pursued with any regularity are the feasible ones: ABSSSI, cUTI, and cIAI, much less CABP.  Yes, the occasional HABP/VABP trial is Continue reading Most Anti-Infective Guidelines Don’t Get No Respect (Let Alone Use!)

No Such Thing as a Free Ride…

..when it comes to FDA review of antibiotic NDAs.  Some seem to have forgotten the dismal record of antibiotic approvals in the last 15 years, and the long list of failed submissions.  Many failed not because of lack of efficacy Continue reading No Such Thing as a Free Ride…

A GO / NO GO decision:  Delafloxacin Stumbles in Gonorrhea Study

The treatment history of N. gonorrhoeae makes for fascinating reading.  This organism has always been able to keep the upper hand in the war of bug versus drug.  Once susceptible to sulfa drugs, to penicillin, tetracyclines and fluoroquinolones, it sequentially Continue reading A GO / NO GO decision:  Delafloxacin Stumbles in Gonorrhea Study

Why Some Did Not Make It

The Circuitous Route to Phase 3:  Another Chapter in the Fitful Development of PTK-0796

When antibiotics change hands, it can be a good thing.  Small companies are often desperate to attract a partner with ‘deep pockets’ to help them finance an expensive late phase development but often have to give up control once the honeymoon Continue reading The Circuitous Route to Phase 3:  Another Chapter in the Fitful Development of PTK-0796

The Difficult Transition Into Phase 3

Preclinical and early clinical development is expensive enough already for VC companies but it gets really expensive in Phase 3.  Hence, not surprisingly, few small companies tackle Phase 3 programs on their own.  Unless an ‘angel investor’ with deep pockets Continue reading The Difficult Transition Into Phase 3

Here They Are: Dalbavancin and Oritavancin – The New Long-Acting Lipoglycopeptides

The development history of glycopeptide drugs is anything but normal.  Daptomycin (Cubicin®) was abandoned by Lilly but resurrected by Francis Tally at Cubist by adjusting the dosing schedule to once daily and careful uptitration.  The drug did superbly in a Continue reading Here They Are: Dalbavancin and Oritavancin – The New Long-Acting Lipoglycopeptides

FDA Adboard on Tedizolid – Why?

FDA’s Advisory Board session for tedizolid (3/31/2014) was a foregone affair:  Looking at the reviewer’s slides, there was really no question about the drug’s efficacy.  Did tedizolid cure as many patients as linezolid?  Yes, it did.  Did the sponsor follow Continue reading FDA Adboard on Tedizolid – Why?
