What does it cost in time and money to run a crash vaccine program against a deadly but infrequent disease that occurs in uninsured and underserved people outside the US? The disease, of course, is Ebola, and the program was announced two weeks ago (GSK press release in FierceVaccines). The program’s goal is to complete safety and efficacy tests in about three months, and its costs will be met in part by a $4 million grant from private and government (UK) sources, GSK, and the US NIH. GSK will also receive funding to manufacture 10,000 doses of the candidate vaccine in parallel to be deployed by WHO if the trials are successful. Such success will not only save lives but may provide a model for crash vaccine development programs against other infectious diseases in the rest of the world which have no or limited vaccines like hepatitis C, malaria, and TB.

An effective drug for treating Ebola is also needed, and recently the US Biomedical Advanced Research and Development Authority announced commitment of up to $42 million (10x what is going into the vaccine program) to tiny Mapp Biopharmaceuticals, Inc. for further testing and manufacture of its candidate drug, ZMapp (FierceBiotech article).

At the other end of the funding spectrum, OncoSynergy, Inc. recently announced the start of a crowd-funding campaign to raise $5,000 to test an antibody it is developing to treat cancer against Ebola (FierceBiotech article FierceBiotech article, OncoSynergy press release, and funding page ). My skeptical side says “PR stunt” but I hope I’m wrong and the company has positive results in its in vitro demo.

In the “Nature doesn’t take a day off” category, FierceVaccines reported that an academic study of the polio virus associated with a 2010 outbreak in central Africa found a new, mutated form (FierceVaccines article). The scary part is that the mutated form was not neutralized in vitro by antibodies generated by the current vaccine. Even more scary was that the outbreak had a 50% mortality rate and it was estimated that half of those affected had been vaccinated. Of course, everyone knows that polio was common in the US with 35,000 cases per year in the 1950s and about 1% resulting in limb paralysis until almost universal vaccination was introduced (CDC Polio FAQ).

In the “lost in the noise” category, Gilead mentioned last week that it is in discussion with six generic drug companies about licensing its anti-hepatitis-C drug, Sovaldi (FiercePharma article and Bloomberg article). According to Gilead’s EVP Gregg Alton, the agreements will bring the drug to about 80 developing countries, and the licensing is in addition to Gilead’s plans to sell Sovaldi in India and other countries for $900 per treatment course. The noise, of course, is that Gilead has priced the same treatment in the US at $84,000 which has generated approbation by some payers and members of Congress. Alton noted, however, that this price is the same as that paid by the payers for the older, less effective regime. So I guess the payers are upset not by the cost of treating (and curing) a patient but by the potential demand for the drug. So the overall cost of the drug is the fault of patients and their doctors.

In the “emerging start-up opportunity” category, MIT reported that researchers of the Singapore-MIT Alliance for Research and Technology had built an MRI-like prototype device for detecting the malaria waste product, hemozoin, in blood (Fierce Diagnostics article and MIT press release). The team is starting a company to develop and test a cheaper, portable version that may be faster and more reliable than the current microscopy-based detection. Not mentioned was another diagnostics company founded by an MIT alum, Disease Diagnostics Group, that is using a simpler technology to detect hemozoin and that its prototype is in field testing (Boston Globe article).
