The ExpeditionMedicine.co.uk crew has a very interesting post about a patient that suffered a splenic infarcture on a Peruvian trip. Something to remember, as this patient had no known history of sickle cell disease or trait.
Thanks for the info!

NICOSAN, FDA Orphan Drug for the Treatment of Sickle Cell Disease
I would like to make you aware that there is a
non-toxic viable treatment for sickle cell in the
world and awaiting application for approval in the
U.S. and E.U. In clinical trials 80% of patients had no
crises and in the refractory 20% crises were reduced
by half.
Through awareness there may come availability for
those who so desperately need it. All it is going to
take is the effort of a few individuals, patients and
doctors to make this drug a reality in the U.S. sooner
than later. Although this drug was developed in
Nigeria, the man behind it, Dr. Ramesh Pandey is a
distinguished biochemist who has worked for the
National Cancer Institute’s (NCI) Frederick Cancer
Research Center as a Senior Scientist, Head of the
Chemistry Section, Abbott Pharmaceuticals and
produced the first commercially viable generic version
of Vancomycin for Lyphomed Inc., a Visiting Professor
at the Waksman Institute of Microbiology at Rutgers,
the State University of New Jersey, holds patents for
biotechnology analysis and rare drug production
processes. He also holds several US and international
patents for paclitaxel and its new analogs. He is a
member of the Editorial Board of the International
Journal of Antibiotics and of several professional
societies. He has been awarded several grants from
NASA, NCI and NIH. The drug NICOSAN has been granted
Orphan Drug Status by both the FDA and E.U..
This new treatment for sickle cell is being produced in Nigeria
by an American pharmaceutical company, trade name NICOSAN®,
and it’s proprietary name is NIPRISAN® . It was developed on the
premise of traditional Nigerian plant based medicinal practices
for the treatment of sickle cell disease.
It has been tested through phase IIb clinical trials and
found to be highly efficacious. Phase III trials have yet
to be completed however it was approved for sale in Nigeria
based on phase IIb trials and toxicity studies which showed
it to be safe and non-toxic.

THE DEVELOPMENT OF NICOSANTM/HEMOXINTM
A DRUG FOR THE MANAGEMENT OF SICKLE CELL DISEASE.
HISTORICAL BACKGROUND

This drug is a major advancement in the treatment of sickle
cell disease unfortunately it is not available in the U.S..
Although the compound has been granted orphan drug status
by the FDA and the regulatory body of the European Union,
to date investigational drug applications for the approval
process have yet to be submitted. Getting a drug approved
in either area is extremely expensive. Until there is
funding available to proceed with the FDA and EU
applications it will be difficult for non-Nigerians to
obtain the drug.
I do say difficult but it is not impossible. If you have a
hematologist or hemoncologist who is willing to put fourth
the effort there are special dispensations available
through the FDA for the importation of unapproved drugs on
a compassionate use basis.
“Expanded access program (EAP). EAPs are typically designed
to provide widespread access to a drug that has proven
efficacy in clinical trials but is still awaiting FDA
approval. They’re similar to standard clinical trials with
a specific treatment plan and certain FDA requirements, but
they have looser patient eligibility criteria. More than
23,000 U.S. cancer patients enrolled in an EAP for Iressa
before it was FDA-approved, for example.”
“Single patient use. This program offers an experimental
drug to an individual patient, rather than a group. The FDA
approves these uses on a case-by-case basis. Decisions are
based on other treatments already available and information
about the drug’s efficacy and potential toxicities.”
http://www.curetoday.com/backissues/v3n3/departments/specialreport/index.html
To date I have no knowledge that anyone has sought any
single use or expanded access from the FDA for Nicosan.
Unfortunately regardless of the dissemination of this
information thus far no one has put forth the effort to
obtain the drug for use.
If just one person would start the ball rolling with a
caring and concerned medical practitioner it could open up
the drug for wide spread use by tens of thousands of
patients across the U.S. Unfortunately thus far the general
response I receive is that people don’t believe that their
physician would be interested in going to this sort of
effort nor do they themselves seem to be inclined to seek
the use of a treatment that could potentially end their
crises.
There has to be at least one physician out there who has
enough care and concern for his patients to be willing to
put forth the effort necessary to obtain this medication
legally. I urge anyone who is effected by sickle cell to
approach their physicians with this information and attempt
to obtain this treatment not only for themselves but for
all patients who could potentially benefit from it’s use.
We already know the benefits of the treatments available in
the U.S. and the E.U.. In many cases they are only
marginally effective or in the case of hydroxyurea cause
side effects so serious that many choose not to use it as
treatment. Here we have an opportunity to use a treatment
that has been shown to be highly effective, eradicating
crises in the majority of patients and reducing crises by
50% in the most refractory cases.
Although the clinical trial group was what the casual
reader might interpret as quite small it is common for
drugs which fall into the orphan drug category to use small
sample groups. Many orphan drugs have been approved based
on very small phase II and phase IIb clinical trials in the
U.S. In the case of FDA fast track status, a drug may be
approved during phase II trials if the drug shows
significant advantage over current approved therapies for
life threatening illness.
Fast Track Designation is a program that, if granted, is
designed to facilitate the development and expedite the
review of new drugs, thereby allowing the FDA to approve
drugs used to treat a serious condition or a
life-threatening disease with less safety data following
the conclusion of phase II studies, rather than phase III,
the normal practice.
The main criterion for a Fast Track Designated drug is the
potential to treat a life-threatening illness or fill a
major unmet medical need. Fast Track may be submitted with
the IND or at any time during the clinical development of
the drug. The Fast Track designation may allow a company’s
application to follow Priority Review, Standard Review, or
a Rolling Review of the application.

Nicosan by Western standards is an extremely inexpensive
drug. It is available in Nigeria without prescription at
$23/month for adults and child doses at $18/month.

I sincerely hope that you find this information helpful. I
would encourage you to forward and post this information
to any person, blog or website where persons effected by
sickle cell anemia can have access to this information.
Feel free to write me with any questions you may have.

About 70% of all sickle cell anemia (SCA) subjects reside in Africa, estimated at over 12 million. The prevalence of SCA is estimated at over 2% while infant mortality is about 8% and survival rate of SCA babies in rural areas by five years of age is about 20%. These statistics indicate that SCA is probably the most neglected (and sometimes forgotten by health authorities) serious public health disorder with serious mortality and morbidity rates in Africa. The objective was to undertake pre-clinical and clinical assessments of a herbal extract vis-à-vis management of sickle cell anemia using Good Laboratory Practice and Good Clinical Practice principles respectively. In Africa, there is no standard treatment for sickle cell anemia, only palliative management is generally available. In view of this situation, most
SCA subjects use herbal medicines. NIPRISAN is a standardized extract from four medicinal/food plants: Piper guineenses seeds, Pterocarpus osun stem, Eugenia caryophyllum fruit and Sorghum bicolor leaves. Short term toxicity study indicated that NIPRISAN was safe in laboratory animals. Bio-activity guided fractionation show that vanillin and aromatic aldehydes may be the bioactive moieties. NIPRISAN reversed sickled red blood cells and
protected them from being sickled when exposed to low oxygen tension. NIPRISAN dose- dependently delayed polymer formation of haemoglobin S. NIPRISAN induced 85% increased solubility of deoxy haemoglobin S. The in vivo efficacy study was undertaken at Children Hospital of Philadelphia, USA. Histological examination of lungs of control Tg transgenic mice carrying human sickle haemoglobin showed entrapment of massive numbers
of sickled cells in alveolar capillaries. NIPRISAN significantly cleared the lungs of sickled cells. Furthermore, NIPRISAN induced profound effect on the survival time of Tg mice under hypoxic conditions (p<0.0001). The phase II clinical data indicated that all the subjects benefited from NIPRISAN with no serious adverse effect. About 80% of the subjects did not experience any crisis during the study (12 months). The subjects experienced significant
reduction in hospital admission while attendance at school profoundly increased. Furthermore, there was no evidence of kidney or liver damage. NIPRISAN has been patented, licensed to an American company, registered and being manufactured at Abuja for
global market.

Elevation in Peru is ….very high….lack of oxygen = body working overtime…especially if body is dealing with sickled cells….
see my blog http://sicklecell-ourvoice.blogspot.com/ I too deal with this illness.
