Glaxo seeks buyer for two of its older antibiotics / AMR podcasts to share

Heads-up … numerous changes in the meeting calendar: Lots of new events as well as rescheduling of previously announced events.

Dear All, A busy start to the week!

First, I’ve received notes expressing concern regarding news that Glaxo is trying to find a buyer for (some of) its antibiotics. With all the angst about the exit of large pharma from the area, this news item looks disturbing on initial glance. But, the news is not what it seems:

  • Here’s a typical version of the news story (link): “Glaxo Revives Sale of Some Antibiotic Treatments”
  • Reading closely, here’s what happening:
    • Glaxo (GSK) has two off-patent cephalosporins (ceftazidime, cefuroxime) for which a buyer has been sought since 2017 (link).
    • GSK is not seeking a buyer for Augmentin.
    • GSK is not stopping its Phase 3 program for gepotidacin: Per (link), the gepotidacin Phase 3 program started 2H19 with a 1200-patient uncomplicated UTI trial (NCT04020341, link) and a 600-patient uncomplicated gonorrhea trial (NCT04010539, link). There is also a 2nd 1200-patient uUTI trial shown starting this month (NCT04187144, link)
  • Putting it all together with a bit of personal speculation:
    • Those two cephalosporins are likely suffering from generic entry.
    • At a corporate level, these two antibiotics are selling at ~$200m/year, an amount that is ~0.5% of GSK’s annual sales of ca. $40b.
    • At a societal level, these two antibiotics are fading in utility due to the rise of resistance (ESBLs in particular)
  • So, this is not a major retreat but rather the kind of business decision that needs to be made on a regular basis.
    • No panic or alarm is needed!
    • But, we can have a good discussion about maintaining supply chain continuity for older antibiotics. I don’t want to go further on this today, but supply chain continuity is one of the 4 incentives proposed by the DRIVE-AB project (link).

Second, the Uppsala Antibiotic Center (UAC, started a podcast series on AMR about 18 months ago. I recorded an interview for their series during the 2019 ICARe course with Eva Garmendia (the coordinator for UAC as a whole) and the podcast has just gone live here. Eva and her colleague Jenny Jagdmann gave me room to talk for about 20 minutes on everything from fire extinguishers (no surprise there!) to non-inferiority trials, after which the two of them carry on a lively 40-minute discussion of both the interview and some relevant current papers.

But my podcast is not the point … rather, I’d draw your eye (rather, ear) to the UAC project’s very multidisciplinary perspective and its messages for the broader antibiotic R&D community. As I have learned time and time again, the best insights come from debates that cross boundaries: learning to see through other eyes is incredibly powerful! My favorite personal example of this is that the phrase “antibiotics are the fire extinguishers of medicine” arose during a spirited hallway discussion between a lawyer (Kevin Outterson) and a medic (me) at a DRIVE-AB meeting in Sweden.  

Thus, I was delighted to see that UAC’s podcast episodes have featured a wide array of disciplines: lawyers, scientists, historians, economists, ethicists, and more. Go to for a full list of prior episodes and have fun broadening your horizons. 

And if you want to dig even more deeply into the social science aspects of addressing the problem of AMR, check out the International Network for AMR Social Science (INAMRSS), an open consortium of international academic centers focused on social science research and policy on AMR (link). INAMRSS is a network of networks and seeks to foster international research collaboration by tying together research leaders from diverse regional, national, and international AMR research centers. Perhaps you can join them … see the link above for more details.

All best wishes, –jr
