Da­ta sug­gest US, UK uni­ver­si­ties fall woe­ful­ly short on re­port­ing clin­i­cal tri­al re­sults

Clin­i­cal tri­al da­ta are used by pa­tients, doc­tors and pol­i­cy­mak­ers to make in­formed choic­es about the ben­e­fits and safe­ty of in­ter­ven­tions — while the meth­ods and re­sults of all tri­als are cru­cial to the pace and di­rec­tion of sci­en­tif­ic progress. How­ev­er, there is a large body of ev­i­dence that sug­gests that com­plet­ed clin­i­cal tri­als are com­mon­ly left un­re­port­ed, and ed­u­ca­tion­al in­sti­tu­tions in the Unit­ed States and the Unit­ed King­dom — ar­guably the two biggest re­gions that breed the bulk of med­ical in­no­va­tion — have emerged as one of the key cul­prits guilty of these vi­o­la­tions.

In the Unit­ed States, Con­gress passed a law in 2007 re­quir­ing tri­al spon­sors — in­clud­ing uni­ver­si­ties — to post the re­sults of cer­tain clin­i­cal tri­als on clin­i­cal­tri­als.gov with­in a year of tri­al com­ple­tion, and a decade lat­er in Jan­u­ary 2017 the rule was fi­nal­ized. Since 2017, 40 lead­ing US uni­ver­si­ties should have post­ed the re­sults of 450 clin­i­cal tri­als — but over a third (31%) of those re­sults are miss­ing, ac­cord­ing to an analy­sis by Uni­ver­si­ties Al­lied for Es­sen­tial Med­i­cines (UAEM) in part­ner­ship with non-prof­it re­search ad­vo­ca­cy group TranspariMED.

The vi­o­la­tors in­clude some of the most ac­tive tri­al spon­sors: For ex­am­ple the MD An­der­son Can­cer Cen­ter, which has on­ly re­port­ed 77% of due tri­als, Mayo Clin­ic (42%), UC San Fran­cis­co (37%), New York Uni­ver­si­ty (21%), and Co­lum­bia Uni­ver­si­ty (17%).

Over­all, 140 clin­i­cal tri­als are still miss­ing re­sults and five uni­ver­si­ties are re­spon­si­ble for half of the un­re­port­ed tri­als: Uni­ver­si­ty of Cal­i­for­nia San Fran­cis­co (17 tri­als with­out re­sults), Co­lum­bia (15 tri­als), Mayo Clin­ic (13), MD An­der­son Can­cer Cen­ter (12) and Chica­go (8), ac­cord­ing to the re­port.

These trans­paren­cy vi­o­la­tions are con­cern­ing con­sid­er­ing at least half of the valu­able med­i­cines that ex­ist to­day were orig­i­nal­ly de­vel­oped in uni­ver­si­ty labs with tax­pay­er fund­ing, in­clud­ing al­most all vac­cines, many HIV and tu­ber­cu­lo­sis drugs, and even in­sulin, the re­port not­ed. Be­tween 2010 and 2016, every sin­gle one of the 210 FDA-ap­proved med­i­cines can be traced back to fund­ing from the NIH, ac­cord­ing to a study pub­lished in the of­fi­cial jour­nal of the Na­tion­al Acad­e­my of Sci­ences.

Mean­while, these trans­paren­cy trans­gres­sions are echoed in the UK. Reg­u­la­tions in Eu­rope are sim­i­lar. Any tri­al of of any med­i­c­i­nal prod­uct con­duct­ed since 2004 in an EU coun­try has al­ready been re­quired to reg­is­ter on the Eu­ro­pean Union Clin­i­cal Tri­als Reg­is­ter (EU­C­TR) and since 2012, spon­sors must en­sure that all reg­is­tered tri­als since 2004 dis­close their re­sults to the EMA with­in 12 months of tri­al com­ple­tion. But the de­lays to the EMA’s soft­ware plat­form pushed the fi­nal date for re­sults post­ing by spon­sors to late De­cem­ber 2016.

Ben Goldacre

In a BMJ study pub­lished in 2018 — led by Ben Goldacre, a best-sell­ing au­thor, med­ical doc­tor and re­searcher who fo­cus­es on un­pack­ing the mis­use of sci­ence and sta­tis­tics in his books Bad Sci­ence and Bad Phar­ma — it was found that in Eu­rope, of the 7274 tri­als where re­sults were due, 49.5% re­port­ed re­sults. Tri­als with a com­mer­cial spon­sor (such as a drug de­vel­op­er) were sub­stan­tial­ly more like­ly to post re­sults than those with a non-com­mer­cial spon­sor (68.1% v 11.0%), the analy­sis sug­gest­ed.

Out of his labs at the Uni­ver­si­ty of Ox­ford, Goldacre set up an EU Tri­al­sTrack­er to con­tin­u­ous­ly mon­i­tor the re­port­ing of tri­als. As of 10 Jan­u­ary 2019, Goldacre and his team have iden­ti­fied 8,062 reg­is­tered tri­als that are ‘un­am­bigu­ous­ly’ due to re­port re­sults — but re­sults on just over half  (53.6%) have been post­ed to the reg­istry. The da­ta, which sug­gest­ed that UK uni­ver­si­ties were less re­li­able than drug de­vel­op­ers, sparked the in­ter­est of House of Com­mons Sci­ence and Tech­nol­o­gy Com­mit­tee. UK uni­ver­si­ties could be brought in front of the com­mit­tee if they fail to im­prove their track record, and the com­mit­tee will ask them to ex­plain them­selves in a fol­low-up ev­i­dence ses­sion if im­prove­ments are not made.

Trump’s HHS claims ab­solute au­thor­i­ty over the FDA, clear­ing path to a vac­cine EUA

The top career staff at the FDA has vowed not to let politics overrule science when looking at vaccine data this fall. But Alex Azar, who happens to be their boss’s boss, apparently won’t even give them a chance to stand in the way.

In a new memorandum issued Tuesday last week, the HHS chief stripped the FDA and other health agencies under his purview of their rule making ability, asserting all such power “is reserved to the Secretary.” Sheila Kaplan of the New York Times first obtained and reported the details of the September 15 bulletin.

Af­ter bruis­ing re­jec­tion, blue­bird and Bris­tol My­ers Squibb land ide-cel pri­or­i­ty re­view. But will it mat­ter for the CVR?

With the clock all but up, the FDA accepted and handed priority review to Bristol Myers Squibb and bluebird bio’s BCMA CAR-T, keeping a narrow window open for Celgene investors to still cash in on the $9 CVR from the $63 billion Celgene merger.

The acceptance comes five months after the two companies weres slammed with a surprise refuse-to-file that threatened to foreclose the CVR entirely. Today’s acceptance sets the FDA decision date for March 27, 2021 – or precisely 4 days before the CVR deadline of March 31. Given the breakthrough designation and strong pivotal data — 81.5% response rate, 35.2% complete response rate — priority review was largely expected.

Flag­ship's merged biotech Reper­toire nets ex-Pfiz­er CSO An­tho­ny Coyle as R&D chief

Flagship is building a big-name C-Suite at its new, $220 million merged biotech.

Repertoire Immune Medicines, which already boasts former Bioverativ chief John Cox as its CEO, announced yesterday that Anthony Coyle, the former Pfizer CSO and the founding CEO of Pandion, will join as their head of R&D.

“As we progress clinical trials for our multi-clonal T cell candidates in immuno-oncology, Tony’s deep expertise in cellular immunology and novel therapeutic development will help us achieve our vision of creating a new class of transformative medicines for patients,” Cox said in a statement.

Can a mag­net­ic cell ther­a­py re­place corneal trans­plan­ta­tion? As eight-year jour­ney leads to the clin­ic, two broth­ers un­veil bold vi­sion

Jeff Goldberg was getting acquainted with a brand new way to do corneal transplants when an even newer, even bolder idea hit him.

It was almost 10 years ago, and Goldberg was in his first faculty position at Bascom Palmer Eye Institute at the University of Miami. Scientists had developed a new way to do cornea transplants where instead of sewing a whole donor cornea — a decades-old practice — they were just engrafting the inner layer of cells.

News brief­ing: Tiny Vac­cinex's drug flops in PhII Hunt­ing­ton's tri­al, stock craters; Siol­ta nabs $30M Se­ries B to de­vel­op mi­cro­bio­me drug

Siolta Therapeutics, a microbiome company targeting allergic diseases, raked in a $30 million Series B to develop its lead candidate, STMC-103H. The drug, which has been FDA fast-tracked, is headed for proof-of-concept trials, according to the company. Its various indications include allergic asthma, food allergies, atopic dermatitis, allergic rhinitis, and allergy prevention.

The news comes just after the California-based biotech added a prominent biopharma veteran as an advisor: 20-year Gilead CEO John Martin. The biotech also gained Richard Shames as CMO, who came by way of Protagonist Therapeutics.

#ES­MO20: Push­ing in­to front­line, Mer­ck and Bris­tol My­ers duke it out with new slate of GI can­cer da­ta

Having worked in parallel for years to move their respective PD-1 inhibitors up to the first-line treatment of gastrointestinal cancers, Merck and Bristol Myers Squibb finally have the data at ESMO for a showdown.

Comparing KEYNOTE-590 and CheckMate-649, of course, comes with the usual caveats. But a side-by-side look at the overall survival numbers also offer some perspective on a new frontier for the reigning checkpoint rivals, both of whom are claiming to have achieved a first.

Signs of an 'Oc­to­ber Vac­cine Sur­prise' alarm ca­reer sci­en­tists. HHS con­tin­ues to claim Azar “will de­fer com­plete­ly to the FDA"

President Donald Trump, who seems intent on announcing a Covid-19 vaccine before Election Day, could legally authorize a vaccine over the objections of experts, officials at the FDA and even vaccine manufacturers, who have pledged not to release any vaccine unless it’s proved safe and effective.

In podcasts, public forums, social media and medical journals, a growing number of prominent health leaders say they fear that Trump — who has repeatedly signaled his desire for the swift approval of a vaccine and his displeasure with perceived delays at the FDA — will take matters into his own hands, running roughshod over the usual regulatory process.

#ES­MO20: Bris­tol My­ers marks Op­di­vo's sec­ond ad­ju­vant win — eye­ing a stan­dard of care gap

Moving into earlier and earlier treatment lines, Bristol Myers Squibb is reporting that adjuvant treatment with Opdivo has doubled the time that esophageal or gastroesophageal junction cancer patients stay free of disease.

With the CheckMate-577 data at ESMO, CMO Samit Hirawat said, the company believes it can change the treatment paradigm.

While a quarter to 30% of patients typically achieve a complete response following chemoradiation therapy and surgery, the rest do not, said Ronan Kelly of Baylor University Medical Center. The recurrence rate is also high within the first year, Hirawat added.

Covid-19 roundup: CDC ad­vi­so­ry com­mit­tee de­lays pri­or­i­ty dis­tri­b­u­tion vote; EU re­port­ed­ly in­dem­ni­fy­ing vac­cine mak­ers

A federal committee that advises the CDC was expected to hold a vote Tuesday on a plan regarding the distribution for initial doses of approved Covid-19 vaccines. But that vote has been scrapped.

The Advisory Committee on Immunization Practices, or ACIP, won’t be voting until the committee members learn more about which vaccines become available first, the Wall Street Journal reported. The vote could potentially wait until a specific vaccine is authorized before recommending how to dole out the first doses.
