Don’t shortchange public trust in science
The need to address COVID-19 is placing huge demands on biomedical research and regulatory processes. Under
pressure, it is essential to uphold high bioethical principles and rigorous standards for the development and
approval of medicines.
T
here is a lot to be said about cutting
through red tape, especially when
human lives are at risk. However,
precisely because of the inherent danger for
human life, shortcuts in the development,
testing and regulatory approval process
for medicines can be extremely risky and
ethically questionable. The COVID-19
pandemic has highlighted this paradox
more than any other medical crisis in recent
memory, as the need for preventative and
therapeutic medications continues to push
against the cautious and strict procedures
that regulate biomedical research and drug
development. The pressure on science to
speed up has been escalating over the course
of the year, and understandably so — the
caseload and death toll of COVID-19 is
enormous, and the burden it poses on
all facets of human life is unprecedented.
Nine months into the pandemic, the world
is in dire need of some good news on the
therapy and vaccine fronts. However, the
persistent focus on speed and the dangerous
politicization of these biomedical efforts
threaten to undercut scientific rigor and
to erode public trust in science at a time
when they are needed most. At this critical
juncture, several recent regulatory approvals
in different countries have been met with
criticism and doubt.
In August, Russia announced that
a vaccine, developed at the Gamaleya
Research Institute in Moscow and
imaginatively named ‘Sputnik V’, received
domestic regulatory approval under a
“conditional registration certificate.”
Rather than expressing excitement
for the registration of the first vaccine
against COVID-19, the international
science world expressed skepticism and
alarm. The urgency of the COVID-19
crisis has led stakeholders to attempt to
condense the development and testing
of vaccines — a process that typically
takes years and necessitates large-scale
testing of safety and efficacy — to a year
or less. Accelerating the process should
not involve bypassing critical steps that
may ultimately jeopardize human life and
health. However, although large-scale phase
3 clinical trials are reportedly planned
for the Sputnik V vaccine, it received
approval after undergoing only rapid and
small-scale early-phase clinical trials. In
fact, the first data on the safety profile and
immune responses elicited by this vaccine
were published at the time of this writing.
This report included findings from two
open, non-randomized phase 1/2 studies
conducted at two hospitals with a total
of 76 participants1 and is already being
scrutinized by the community.
On the heels of this news came the
announcement that medical professionals
and state employees who were deemed to be
in high-risk professions in China had been
receiving inoculations of an experimental
vaccine developed by Sinopharm’s China
National Biotec Group Company since
July, under an “urgent use” process. In
this case also, phase 3 trials are underway,
and scientific results about safety and
efficacy are shrouded in secrecy. Earlier
this summer, China had authorized a
different experimental vaccine developed
by the Beijing Institute of Biotechnology
and CanSino Biologics specifically for
military personnel under a “military
specially-needed drug approval.” Given the
paucity of information on these vaccines,
questions remain about the risks they might
pose for the people receiving them.
In the USA, the Commissioner of the
Food and Drug Administration (FDA)
recently stated his agency’s willingness to
approve a vaccine before the completion
of phase 3 trials, if benefits outweighed
risks. Similar to the Russian “conditional
registration certificate” and the “urgent
use” protocol in China, the FDA can issue
an “emergency use authorization” for
medicines before clinical trials are complete,
and such authorizations can be revoked
if the medicines are deemed harmful or
not beneficial. However, the possibility
that the FDA might fast-track a vaccine
approval came as an additional hit to its
already shaken credibility after some key
missteps this year. When an emergency use
authorization of hydroxychloroquine and
chloroquine was issued in March on the
basis of limited data, it was welcomed as a
major breakthrough by the administration
and part of the media, only to be revoked
in June when the lack of clinical benefit
and serious safety concerns became clear.
This was followed by another debacle in
Nature Cancer | VOL 1 | September 2020 | 855–856 | www.nature.com/natcancer
August, this time involving the emergency
use authorization of convalescent plasma
that was announced amid great fanfare
at a White House press briefing and was
hailed by the FDA as “another achievement
in the administration’s fight against the
pandemic.” The criticism by the scientific
world, including the COVID-19 Treatment
Guidelines Panel of the US National
Institutes of Health, was sharp and swift.
Critics noted the overall limited and
inconclusive evidence to support this
decision, the grossly misleading statements
at the press briefing on the data in support
of the clinical benefits of plasma for patients
with COVID-19, and the highly political
tone of the announcement. It should also
be noted that such emergency measures in
the absence of a solid scientific and clinical
foundation can delay effective treatment
evaluation in the long term, as they may
undercut enrollment and completion of
phase 3 trials, given that participants would
face the possibility of receiving a placebo
rather than an already authorized therapy.
The FDA commissioner acknowledged
through social media that the criticism
about the description of convalescent
plasma data was justified and has repeatedly
defended his agency’s decisions and
dismissed concerns about political pressure.
On the topic of COVID-19 vaccines, he
stressed that decisions would be based on
science, medicine and data, rather than
politics, and committed to a transparent
process, noting that an independent group
of experts is tasked with advising the FDA
after reviewing data on COVID-19 vaccines.
Along the same lines, the chief executive
officers of nine drug companies have issued
a joint pledge to “stand with science” and to
submit their candidate vaccines for approval
or emergency use authorization only after
safety and efficacy have been demonstrated
through phase 3 clinical studies compliant
with the requirements of expert regulatory
authorities such as the FDA.
Such assurances are welcome, especially
as vaccines are administered to healthy
people as a preventative measure and thus
should be held to higher standards with
respect to potential risks and the rigor of
the testing and approval process. Recent
