Just 11 people work inside a 150-sq.m. rented prefab building in the “Hi-Tech
Village” on the edge of the Hebrew University of Jerusalem’s Givat Ram campus.
The Oramed Pharmaceuticals company, which until a few weeks ago occupied an
even-smaller space a few steps away, buys only secondhand furniture – not
because CEO Nadav Kidron and chief scientific officer Miriam Kidron – his
biochemist mother – are cheapskates. They are just modest, and Oramed is a
public company with stockholders and investors behind it.
Kidrons’ eight-year-old biotech firm is currently the world’s best hope for an
oral insulin capsule, which could improve the lives and health of 400 million
diabetics – both type 2 and type 1 – around the world.
Jerusalem company has for years been issuing press releases about its progress
in producing such a revolutionary capsule and the product is estimated at being
around five years away – if all goes well, the Kidrons predict that 2014 will be
the most important year in its history.
“We asked the US Food and Drug
Administration (FDA ) for permission to conduct phase 2 clinical
They said we first needed a safety study, so we did it on 30
people in Orange County, California, at the Integrium company. We are waiting
for results. If they are proven successful, as we expect, we can go into phase
2-b trials,” said the chief scientific officer in an interview at the company.
“We can always make changes if necessary.”
While it has fewer than a
dozen employees including the Kidrons, the company boasts a very prestigious
scientific advisory board that includes Nobel Prize laureate Prof.
Hershko; former Pfizer pharmaceuticals executive Dr. Michael Berelowitz; former
Bausch & Lomb CEO Gerald Ostrov; and Mount Sinai School of Medicine diabetes
expert Prof. Derek LeRoith.
Injected insulin was first produced in 1921
by Canadian surgeon Dr.
Frederick Banting and his assistant, medical
student Charles Best, and it saved victims of type 1 diabetes, an autoimmune
condition in which the islands of Langerhans in the pancreas were destroyed by
the body, and that was inevitably fatal.
From that early event,
scientists searched for an oral insulin pill to make the self-injections several
times a day unnecessary.
Although there are oral pills to treat type 2
diabetes, which usually results from lack of physical activity, overweight and
poor diet, and sometimes as a result of emotional stress, they gradually lose

“The best animal model is the pig, but when we offered proof
that our delivery system worked on healthy people, we no longer had to try it on

said. “We introduced a substance that delays action of proteolytic activity and

got interested in it because I worked with Hanoch. But already in 2006, when we
founded the company, we knew what a plague diabetes would be, as the obesity
epidemic had long been underway,” said Miriam.
“Since then, our capsule
has gotten a lot of attention at medical conferences.
We have published
numerous articles in prominent medical journals, and we were very visible at the
American Diabetes Association’s meetings.”
The Oramed team experimented
with their oral delivery system for type 1 and type 2 diabetes of ordinary
insulin on rats and then dogs, but the experiments were for some reason not
reproducible. “But then we added an oil, and suddenly, the good results could be
repeated,” Miriam continued. “It’s the same white capsule for both types, but
different indication. The type 2 pill would be given once daily before going to
sleep and vastly improve insulin-blood sugar balance,” Miriam said, while for
insulin-dependent (type 1) diabetes, patients would not stop injecting
themselves but they would need fewer shots. For this, the capsule would be taken
before meals three times a day.

Meanwhile, Nadav received a degree in law and a master’s degree
in business administration and was instrumental in the founding of Oramed and
running it since then.

NovoNordisk has been working on its own oral insulin capsule –

say Oramed is at the most advanced stage and has its own delivery-system patents
in Israel, Europe, Japan, New Zealand and elsewhere. “We hope to have patent
protection in the US in 2014. We are like David and Goliath,” Miriam suggested
with a smile. “NovoNordisk is only completing phase 1 studies. The two companies
also work independently and are not working cooperatively.”
staff seems to be exceedingly small. “We outsource other jobs such for medical
writing, dealing with regulatory authorities and consultancy,” Nadav explained.
“We have the same philosophy about diabetes as Pfizer had about cholesterol. It
developed its Lipitor pill to bring down blood cholesterol and thus
significantly reduce the risk of heart disease.

less likely to need insulin injections. The savings are huge, as more than half

insulin is absorbed and can be seen in the blood, so their blood sugar level

They continued giving themselves injections, but the

‘WE KNOW the capsule, simply called

Oramed has investors from New York, including the Sabby
Healthcare Fund and The AWM investment company. The chief scientist’s office of
the Economy Ministry invested NIS 6.5m. in 2009 as well.
Oramed was first listed on NA SDA Q. The stock value has almost doubled to $13
per share in that time.
“Of around $40m. invested in us, we have more
than $20m. in the bank. We spent the money on pre-clinical and clincial trials,
production, regulation work and patents,” said the lawyer. “The CEO of a large
American pharmaceutical company told me, ‘You managed to do everything so far at
only 10% the amount it would cost a US company.’ The huge international
pharmaceutical company Pfizer abandoned its nasal-spray insulin delivery system
in 2007 and lost a great deal of money.”

It has also developed an oral GLP1 analog, oral exenetide.
At present, the hormonal drug for diabetes, known commercially as Byetta, must

preparation could minimize such a side effect and make exenitide much more
attractive to patients. A third product being developed is a combined oral
insulin and oral exenatide capsule.
Oramed has a third product in the
pipeline that combines oral insulin and oral exenatide. So far, only animal
studies and not human trials have been performed, but the results have been
promising, Miriam said.
Modest through it all, the Kidrons make great
efforts not to make promises.
“We haven’t even considered a commercial
name yet for our insulin capsule. Five years away for production is realistic.
We learned that we can’t exaggerate or make promises,” said Miriam.
