    The Novavax Vaccine Data, and Spike Proteins in General

    1. Novavax Clinical Data Word came yesterday that Novavax had very good safety and efficacy in the trial of their recombinant protein vaccine. This is good news. By this point, the vaccine is much less needed here in the US, but it could be a very important part of getting many other countries vaccinated, due to… Read More

    Blood Clots and the AZ Vaccine, Revisited

    Once again, what’s going on with vascular events and the AZ/Oxford vaccine? I last wrote about this situation a couple of weeks ago, and it’s taken some real turns since then. At that point several EU countries had suspended dosing, but over the next week several began administering the vaccine again after the European Medicines… Read More

    Cancer and Gene Therapy

    Update, March 10: Bluebird has reported data that makes it much less likely that this even was due to their lentivirus vector. Good news, and I hope it holds up. There’s news today that Bluebird has suspended its gene therapy work on sickle cell disease because of two cases of cancer in its treatment population. Read More

    What Might Go Wrong

    With all of my posts here about vaccines and antibodies, it’s only fair that I spend some time talking about the potential toxicology problems with both of those. I remain optimistic about both categories, but it’s for sure that not all the candidates being advanced are going to make it through. So what sorts of… Read More

    Crossing Fingers

    I’ve mentioned it in passing before, but it bears repeating: this is a really unusual moment in drug discovery. We have simultaneously more new modes of action for therapy coming on in the clinic than I can ever recall, and some older ones are getting reworked to join the action. This short overview is a… Read More

    Vitamin C and Immuno-oncology

    Linus Pauling was a fearsomely great scientist who is remembered by the general public for his advocacy of megadoses of Vitamin C, a favorite topic of his later in life. Infectious disease, cancer: Pauling advised gram amounts of ascorbic acid and had a lot of theorizing to offer about why that was beneficial. So while… Read More

    Idiosyncratic Tox

    It’s our high failure rate in clinical trials that makes the drug industry what it is. And two of the biggest factors in that failure rate are picking the wrong targets/mechanisms, and unexpected toxicity. The first is clearly a failure of our understanding of human biology, and the only remedy I can see for that… Read More

    N-Acetyl Cysteine: A Warning Shot

    I’ve highlighted several articles here over the years that cast doubt (to say the least) on the popular belief that Antioxidants Are Always Good For You. These other views do not seem to have penetrated the public consciousness yet, though, to judge by the way that foods and supplements are advertised. Today brings another example… Read More

    Unfolding the Unfolded Protein Response.

    When you look closely at cellular biochemistry, what you see are a lot of amazing processes that are surrounded by amazing amounts of redundancy, backups, patches, and accumulated tweaks and fixes. That’s evolution for you; these things have been piling up for a billion years or two, and we’re all the descendants of the critters… Read More

    No Pain, and No Worries?

    The FAAH (fatty acid amide hydrolase) enzyme system has provided a number of headlines over the years. FAAH itself is involved in the brain’s endocannabinoid system – it clears neurotransmitters like anandamide – and a number of other biologically important hydroxyethylamide and acyltaurines. So the potential for inhibitors of it… Read More
