The highlights of the year 2015 for me begin with the discovery
of the iChip technology by Stava Epstein and his colleagues in Kim Lewis’ lab.
This technology allows the growth of previously non-cultivatable
antibiotic-producing organisms from soil by simply isolating them and placing
the back in the soil environment from which they came. Its elegant and holds
much promise for the discovery of novel natural product antibiotics in the
future. We are all awaiting further developments here.
The output of reports
from Jim O’Neill’s Review on Antimicrobial Resistance continues to amaze me even if I don’t
agree with all their conclusions. The idea that incentives for the discovery and development of antibiotics could
actually become reality in my lifetime is nothing less then a breath of air
after the stifling nightmare of the last 15 years. I have been so inspired that
I have joined the Drive-AB effort to help make
this dream come true.
This year finally saw the results of Astra-Zeneca’s efforts
to sell its antibiotic research, development and business franchise. Being unable to obtain the price they were
demanding (one presumes), they adopted a different strategy. This year they spun
out their discovery group into a company, Entasis, fully funded to the tune
of $40 million by the mother ship (AZ).
Shortly after that, they announced
the formation of an independent business unit within AZ that would encompass
their antibiotics business and as well as their clinical development group.
What will happen to them is still to be determined – but I will have more to say
about this in the next week or so.
A big highlight for me this year, and I hope for you, too,
was the appearance of my new book – The
Drug Makers. I have been gratified
by the many positive comments I have received from those within and from many
outside of the pharmaceutical industry.
On a down note, Tetraphase reported
that their phase III trial of eravacycline for complicated urinary tract
infection failed to meet its endpoint. I was especially disappointed in this
news because I helped them design the trial and thought that we had done
everything to assure its success. Luckily, I own no Tetraphase stock since it
crashed by about 80% with this news. I am still hoping that eravacycline will
make it to the marketplace since we desperately need an effective, oral
antibiotic for resistant Gram-negative infections. Eravacycline is the only drug fitting this
bill on the near term horizon.
On another low point, I discussed
the effect of increasing drug prices, especially for generic drugs, on public opinion and even on pharmaceutical company stock prices and on the political campaign. I suggested that the US should adopt two simple (but politically fraught) policies to deal with this issue. (1) We should subsidize alternative manufacturers for essential
medicines to prevent price gouging. (2) The US should finally begin to
negotiate drug prices nationally at least on a federal level just like
virtually every other country in the world.
This is guaranteed to control prices.
While some argue that it will reduce innovation globally and here in the
US, I remain unconvinced and believe we should do the experiment.
The recent announcement of the proposed merger between
Pfizer and Allergan was the subject of a blog
and a recent Lancet
article. My worry is that Allergan’s key antibiotic pipeline for North America
based on the beta-lactamase inhibitor, avibactam, will be in jeopardy because
of this merger. Pfizer is not known for its enthusiasm for antibiotics these
days.
A recent court ruling suggesting that the promotion of
off-label uses for drugs was protected speech raised
my hackles. If this ruling ever
becomes the law of the land, it will mean that companies can sell anything for
anything. Lets not go there – please.
Finally, the recent emergence of mcr-1, the plasmid-mediated
gene encoding resistance to our very last line Gram-negative antibiotic
polymyxin (colistin) scared
the hell out of me. The gene has now been found in Asia and in Europe after
having apparently emerged in China. Why
did this occur? Because in China (and
apparently here in the US) polymyxin can be used and has been used as a growth
promoting agent for pigs and/or cattle. In an editorial,
Josh Bloom and I suggested that this practice must stop and must stop globally.
With that, I wish you all a happy, productive and very safe
2016!
