Entertaining Engineer: Prud’homme


Gathered to hear Bob Prud’homme speak at the Princeton Chamber breakfast was a contingent from Princeton United Methodist Church. In this quickie snap, from left: Bruce Henry, Barbara Fox, Prudhomme in back, Jamileh Gerber in front, Dana Dreibelbis in back, Daniel Shungu in front. Also attending from Princeton UMC: Ed Sproles and Doug Fullman.

Scientific “war stories” were on the agenda today, as Bob Prud’homme entertained members of the Princeton Regional Chamber at the Nassau Club. Some of the twists and turns of his 40-year career at Princeton University revealed good news, some not so good.

In the disheartening category was the realization that, since virtually no drugs are manufactured in the United States, the U.S. stands to lose significant intellectual capital re drug development.

Why? A therapy doesn’t leap from lab to assembly line. It undergoes translation from research to retail in a “pilot” manufacturing plant, where veteran managers and supervisors can keep close tabs on quality control. Until recently the major pharmas built those pilot plants in the U.S., supervised by U.S. managers. If all the pilot plants move overseas, technical managers in the other countries will acquire that extremely valuable expertise.

On the heartening side, Prud’homme says he often finds himself working with research scientists in Asia whom he knows – because they were his students and collaborators at Princeton. Surely this answers any chauvinistic assertions that U.S. schools should limit the number of students from abroad.

IMG_4615In the good news category, Prud’homme and his collaborators get money from the Bill and Melinda Gates Foundation to develop drugs for global health. (UFAR founder Daniel Shungu, seen chatting with Prud’homme before the breakfast, is also the recipient of Gates funds.) What can sell in a blister pack at CVS won’t work for a third world country, which needs drugs to be packaged in jars that will last for six months in a hot damp climate. Princeton’s engineering quad leads the industry in meeting the need for these opportunities in drug delivery.

Only inexpensive drugs can be brought to poor countries. In contrast, cancer therapies are so costly that they can’t be used in the Third World. Prud’homme worries that cancer therapies will even be too expensive for OUR country’s insurance capacity, and that our healthcare business plans are in danger. Either our healthcare insurance will topple, or it will be outrageously unequally distributed, or the people will make decisions about what gets covered and who doesn’t.

One fix would be to deny $60,000 immunotherapy if it won’t prolong life by at last a year. Another way is to adopt the single-payer system used in Australia and make the hard decisions. “I worry about the future of our healthcare system,” says Prud’homme, “and that we will have an unjust society. What problems are we willing to live with?”

Prud’homme memorably described the ins and outs of nanotechnology in clear terms. The challenge for using nano in injectable drugs is that the drug might disperse too quickly, before it reaches the target site. The difficulty with using nano molecules in oral therapies is that many molecules are hydrophobic. They do not live comfortably in water.

His lab, successful in conquering both challenges, has been selected as the “academic lab of choice” by the major pharmas. The story behind that reinforces MY conviction that our town is ever so fortunate to have this university and these research labs at our doorstep.

Many complain that because the university has “deep pockets” it should pay more in lieu of taxes. Exactly because Princeton University has those deep pockets, it can afford to offer generous terms to potential partners. Someone asked how scientists can get molecules through the patent process without revealing secrets to competitors. The answer, says Prud’homme, lies in the university’s motto “Princeton in the Nation’s Service.”

Nobody has approved this metaphor, but here’s how I would explain it. You have five pirates at your door for Trick or Treat, almost identically costumed. One has a face mask, Pirate X. When a big pharma (BASF, GSK, Pfizer, Merck – all Princeton collaborators) wants to secretly develop a molecule, Princeton sends all five to the patent office, revealing the identity of four, leaving one unidentified. This gives the big pharma lead time to develop Molecule X. (Somebody please comment if this comparison doesn’t work.)

Princeton University came late to the entrepreneurial market becauase. as Prud’homme acknowledged, research suitable for the commercial market used to be scorned by the academics. Princeton was one of the most hoity-toity of universities in condemning research that results in a salable product.  He credits the philosophy of John Ritter  (in charge of technology licensing) and the success of two researchers – Steve Forrest and Edward C. Taylor – with changing the university’s attitudes about the inviolable sanctity of basic research. Forrest (now at the University of Michigan) channeled his research on organic light -emitting diodes (OLEDs) into a start-up, Universal Display Corporation that leads the market for displays for smart phones and has revenues of more than $300 million. Taylor developed the cancer-fighting drug, Alimta, and the proceeds from that virtually paid for the university’s new chemistry building.

With its generous endowment, the university does not have to nickel-and-dime its collaborators, and its scientists and engineers can be “in the nation’s service.”


Eric Newton: Cancer Survivor



Here is a link to my story in this week’s U.S. 1 Newspaper, on stands until Wednesday, December 16.  It’s about Eric Newton, pictured above with his daughter Jasmine. He had the same kind of cancer that my husband had — George’s was diagnosed early and he is fine now. And the same kind of cancer that my cousin had, but hers was not diagnosed early enough. Eric’s prognosis was grim until he entered a Phase II clinical trial of an immuno therapy drug similar to the one that has given Jimmy Carter a new lease on life. It’s an exciting development.
