General Information
714-X was developed more than 30 years ago in a privately funded laboratory in
Quebec, Canada, where it continues to be produced. The primary component of
714-X is naturally derived camphor that is chemically modified by the introduction
of a nitrogen atom. After modification, the camphor is combined with
water and sodium chloride (i.e., salt). Numerous trace elements have also been found
in batches of 714-X.[1] Reviewed in [2]
The private laboratory markets 714-X worldwide through its own distribution
company.[1] In Canada, this compound is legally available on compassionate grounds
only and must be obtained through a physician. [1] Reviewed in [2] Because the production of 714-X is not regulated, there is no
guarantee that rigorous quality control procedures are followed to ensure
manufacturing consistency or product safety. The U.S. Food and Drug Administration (FDA) has not approved 714-X for use as a treatment for cancer or any other medical condition. In addition, the FDA has placed an import ban on 714-X. At least one distributor has been convicted of violating this regulation and received a 1-year prison sentence.[3]
Before researchers can conduct clinical drug research in the United States, they must file an Investigational New Drug (IND) application with the FDA.
The IND application process is confidential, and information about an IND can
be disclosed only by the applicants. To date, no investigators have announced
that they have applied for an IND to study 714-X as a treatment for
cancer.
714-X is usually administered by injection near lymph nodes in the groin. It can also
be administered nasally, using a nebulizer. Nasal administration is used
for follow-up treatment and for the treatment of patients with lung or oral cancers. The producers of 714-X do not
recommend intravenous or oral
administration. A usual treatment cycle consists of a single daily injection
for 21 days followed by a 2- to 3-day rest period. Between 6 and 12
treatment cycles have been recommended by the producers. The producers of 714-X advise a 50%
reduction in dose for pediatric patients who weigh less than 30 kg (66 lb).[1] Reviewed in
[2]
It has been suggested that 714-X is more effective if administered early in
the disease process and before surgery, chemotherapy, or radiation therapy. The
producers claim, however, that 714-X can also be used in conjunction with conventional treatments. It
has been further suggested that the use of alcohol and treatment with
nonconventional therapies such as shark or bovine (i.e., cow) cartilage (and other angiogenesis inhibitors),
and vitamin B12 and vitamin E supplements be avoided during 714-X
treatment.[1] Reviewed in [2]

History
Little documentation exists regarding the development of 714-X and its
mechanism of action. It appears to have been developed in the 1960s on the
basis of earlier studies that used a high-magnification, dark-field microscope called
a somatoscope. Reviewed in [1,2] With the somatoscope, researchers were able
to examine living cells in samples of fresh blood and tissue taken from
healthy individuals and individuals with serious diseases, including cancer.
The study of living cells (as opposed to the dead cells examined with a
conventional light microscope or an electron microscope)
led to the theory that microorganisms distinct from bacteria, viruses, and fungus exist normally in the blood and play
a role in the development of cancer. These microorganisms, which were called
somatids, are said to exist in multiple forms, some of which appear only in
individuals affected by degenerative or malignant diseases. The forms associated
with degenerative diseases or cancer reportedly secrete growth hormones and toxic substances that disrupt
normal cellular metabolism and damage
the immune system. In this compromised environment, cells that have become cancerous are allowed to proliferate. It was also suggested
that cancer cells trap nitrogen, thereby depriving the rest of the body of the
nitrogen needed for normal cellular metabolism. In addition, it was proposed
that cancer cells secrete a toxic substance, cocancerogenic K factor, that
further inhibits the immune system. Reviewed in [1,2]
The producers of 714-X state that cancer can be diagnosed, and its
development and spread can be predicted by studying blood samples with the
somatoscope. No evidence has been published in peer-reviewed scientific
journals to support these proposals, and the somatidian theory of cancer
development is not widely accepted.
714-X reportedly works by protecting, stabilizing, and reactivating the
patient’s immune system, so the body can defend itself against cancer cell
growth and metastasis.[3] Reviewed in
[1,2] 714-X is said to accomplish this, in part, by helping to increase the
“fluidity” of lymph.[3] In addition, the camphor component of 714-X is purportedly attracted to cancer cells, where the
added nitrogen is released, thus preventing malignant cells from depleting the
nitrogen required by normal cells (including immune system cells) for proper
metabolism and function. Reviewed in [1,2]

Laboratory/Animal/Preclinical Studies
No laboratory study of the safety and/or effectiveness of 714-X has been
published in scientific literature. A few animal experiments have been
conducted, but the results of these experiments have not been reported in
peer-reviewed scientific journals. The animal studies utilized a lymphosarcoma tumor model in rats and lymphoma tumor models in dogs and cows.
714-X was not found to be effective as an anticancer treatment in these
studies. Reviewed in [1]
A few laboratory and animal studies have suggested that camphor is able
to enhance the response of the immune system to vaccine administration and to increase the sensitivity of tumor cells to radiation therapy.[2-6] In one series of
studies, investigators used camphor vapors as a conditioned stimulus to
promote an immune response.[2-5] These studies demonstrated that mice exposed
to camphor vapors at the same time they received an antilymphoma vaccine
showed decreased growth of transplanted lymphoma cells and increased survival
when they were re-exposed to camphor vapors plus the vaccine or to camphor
vapors alone, in comparison with mice re-exposed to only the vaccine.[2,3]
These investigators also demonstrated that exposure to camphor vapors led to
an increase in natural killer
cells [4] and an increase in tumor-specific cytotoxic T cells.[5] Another
study reported that breast adenocarcinoma cells transplanted
under the skin of mice responded better to local radiation therapy when small doses of camphor were administered by intraperitoneal injection before
the radiation treatment.[6]
Finally, researchers examined nine compounds, including a
camphor-containing compound, for their ability to inhibit the activity of
estrone sulfatase, an enzyme involved in the production of estrone, which is a
precursor of the various forms of estrogen. Estrogens are thought to
promote the growth of hormone -dependent breast cancer cells. The
camphor-containing compound showed only modest inhibition of estrone sulfatase
activity in human breast cancer cells grown in vitro.[7]

[PUBMED Abstract]
Overall Level of Evidence for 714-X
To assist readers in evaluating the results of human/clinical studies of complementary and alternative medicine (CAM) treatments for cancer, a scoring system has been devised that allows
studies of individual treatments to be ranked according to the strength of
their evidence (i.e., their level of evidence). Not all studies, however,
are given a level of evidence score. To be eligible, a study must:
- Evaluate
a therapeutic outcome(s), such as tumor response, improvement in
survival, or carefully measured improvement in quality of life.
- Be reported in
a peer-reviewed scientific journal.
- Have its clinical findings
published in sufficient detail that a meaningful evaluation can be made.
Evidence from studies that do not meet these requirements is considered extremely weak. In addition to scoring individual studies, an overall level of evidence assessment is usually made.
Because no study of the use of 714-X in humans has been reported in a
peer-reviewed scientific journal, no level of evidence analysis is possible
for this treatment. Therefore, at this time, the use of 714-X as a treatment
for cancer cannot be recommended outside the context of well-designed clinical trials.
