What is DCA

Sodium Dichloroacetate (DCA), is a chemical compound, known since 1864, that improves human energy production (mitochondrial function) and promotes cancer cells to recede and commit suicide (apoptosis).

DCA is a white powder that easily dissolves in water. It is essentially odourless and tasteless.

Is DCA Safe?

is It safe to consume at least 12.5mg/kg of DCA a day.?

15 Month Treatment with DCA Revealed No Blood, Liver, Kidney or Heart Toxicity.
We treated patients with a starting dose of 12.5 mg/kg orally twice a day for 1 month, at which point the dose was increased to 25mg/kg orally twice a day. We then followed a dose de-escalation protocol, decreasing the dose by 50% when dose-limiting toxicity (temporary peripheral neuropathy) occurred. The patients were followed clinically [and administered DCA] for up to 15 months. None of the patients had hematologic, hepatic, renal, or cardiac toxicity. Peripheral neuropathy was the only apparent toxicity. Patients had variable dose-dependent degrees of peripheral neuropathy, which was reversible, confirming previous studies. When the dose was decreased to 6.25 mg/kg orally twice a day, none of the patients had clinically significant peripheral neuropathy.

DCA Promotes Cancer Cell Suicide (apoptosis) and Inhibits Cancer Growth
The unique metabolic profile of cancer (aerobic glycolysis) might confer apoptosis resistance and be therapeutically targeted. Compared to normal cells, several human cancers have high mitochondrial membrane potential (DeltaPsim) and low expression of the K+ channel Kv1.5, both contributing to apoptosis resistance. Dichloroacetate (DCA) inhibits mitochondrial pyruvate dehydrogenase kinase (PDK), shifts metabolism from glycolysis to glucose oxidation, decreases DeltaPsim, increases mitochondrial H2O2, and activates Kv channels in all cancer, but not normal, cells; DCA upregulates Kv1.5 by an NFAT1-dependent mechanism. DCA induces apoptosis, decreases proliferation, and inhibits tumor growth, without apparent toxicity.

Five Patients with Brain Cancer Treated with DCA
Five patients who had brain cancer (glioblastoma) were treated with oral DCA for up to 15 months. The dose-limiting toxicity was a dose-dependent, reversible peripheral neuropathy, and there was no hematologic, hepatic, renal, or cardiac toxicity. Indications of clinical efficacy were present at a dose that did not cause peripheral neuropathy.

Patients 1 to 3 had already failed Radio Therapy and Chemotherapy and were considered terminal prior to starting DCA. Patients 4 and 5 were newly diagnosed.

•Patient 1: Before and after tissue samples showed decreased proliferation and increased cancer cell death (apoptosis). Also evidence of tumour regression seen by MRI scan.

• Patient 2: Cancer no longer visible on MRI or PET scan

• Patient 3: Before and after tissue samples showed decreased proliferation and increased cancer cell death (apoptosis). However this patient had a very large tumour, with brain edema at the start. They continued to deteriorate and died 3 months into the trial from brain edema.

• Patient 4: Before and after tissue samples showed decreased proliferation and increased cancer cell death (apoptosis). Also evidence of tumour regression seen by MRI scan.

• Patient 5: No after tissue samples taken but evidence of tumour regression seen by MRI scan.
All patients, except patient 3, were clinically stable at month 15 and alive at a month 18 telephone follow-up.

Type of Response to DCA Treatment

Their treatment regimen is typically 20-25mg/kg/day with a cycle of two weeks on DCA and one week off

The Pharmacology of DCA
Dichloroacetate (DCA) exerts multiple effects on pathways of intermediary metabolism. It stimulates peripheral glucose utilization and inhibits gluconeogeneis, thereby reducing hyperglycemia in animals and humans with diabetes mellitus. It inhibits lipogenesis and cholesterolgenesis, thereby decreasing circulating lipid and lipoprotein levels in short-term studies in patients with acquired or hereditary disorders of lipoprotein metabolism. By stimulating the activity of pyruvate dehydrogenase, DCA facilitates oxidation of lactate and decreases morbidity in acquired and congenital forms of lactic acidosis. The drug improves cardiac output and left ventricular mechanical efficiency under conditions of myocardial ischemia or failure, probably by facilitating myocardial metabolism of carbohydrate and lactate as opposed to fat. DCA may also enhance regional lactate removal and restoration of brain function in experimental states of cerebral ischemia. DCA appears to inhibit its own metabolism, which may influence the duration of its pharmacologic actions and lead to toxicity. DCA can cause a reversible peripheral neuropathy that may be related to thiamine (B1) deficiency and may be ameliorated or prevented with thiamine supplementation.

DCA as Therapy for Blocked Arteries and Heart Failure
Short-term clinical and laboratory experiments demonstrate that intravenous DCA rapidly stimulates pyruvate dehydrogenase enzyme complex activity and, therefore, aerobic glucose oxidation in myocardial cells. Typically these effects are associated with suppression of myocardial long chain fatty acid metabolism and increased left ventricular stroke work and cardiac output without changes in coronary blood flow or myocardial oxygen consumption. Although long-term studies are lacking, short-term parenteral administration of DCA appears to be safe and capable of significantly improving myocardial function in conditions of limited oxygen availability by increasing the efficient conversion of myocardial substrate fuels into energy.

Is DCA safe?
DCA has been used in humans to treat a rare disease called “congenital lactic acidosis”, and found to have some mild to moderate side effects. Our experience so far suggests that DCA is safe to use in cancer patients under close medical supervision.

Some animal studies show that DCA can itself cause liver cancer. These studies used doses which are over 1000 times higher than what would be prescribed for cancer treatment.

We think that DCA can have 2 main categories of side effects:

Nerve injury in the hands and feet (“peripheral neuropathy”). Neuropathy typically takes several weeks to months to develop, and is reversible if it is caught early. In the existing literature, neuropathy from DCA appears to be age-related. We suggest vitamin B1 (benfotiamine or thiamine) and alpha lipoic acid to prevent and reduce the severity of peripheral neuropathy.

Sedation, confusion, hallucinations, memory problems, hand tremors. These side effects appear to be dose-dependent, and age-dependent which is consistent with existing human research on DCA.

We use sustained release alpha lipoic acid to prevent/reduce these side effects. Patient feedback suggests that this supplement is effective.

Heartburn, nausea, vomiting, indigestion. These side effects may occur with DCA,

Other Side Effects:
Some patients experience pain at the sites of their tumour(s) within the first few days of starting DCA. This may be an indicator of the effectiveness of DCA.

Most side effects reported so far have been mild or moderate. Patients experiencing moderate side effects are usually taken off DCA as a precaution. Most side effects typically resolve within days after stopping DCA. Neuropathy can take weeks or months to improve.

TLS (Tumour Lysis Syndrome)
This is a condition in which a large number of tumour cells are rapidly killed, causing a sudden release of the contents of the dead cells into the bloodstream. It can result in abnormal heart rhythms, and kidney failure. A detailed reference article can be found here. TLS occurs most commonly in patients with a large mass of tumour cells in the body who receive chemotherapy, especially with lymphomas or acute leukemia. Since DCA can enhance the effect of chemotherapy in certain cases, it may be more likely to occur if DCA is combined with chemotherapy (especially without medical supervision).

DCA-Drug Interactions
Drugs that can cause confusion or hallucinations have a potential to interact with DCA. This may include cannabinoids, benzodiazepines and other CNS drugs. Patients NEED to consult their physicians for potential drug interactions.


DCA and Caffeine
We have received a large number of inquiries about caffeine following some anecdotal reports of enhanced DCA effect with excessive tea/caffeine intake. After conducting a limited review of our DCA patients, we have noted that patients who have shown an excellent response to DCA do not take tea/coffee or caffeine or take it in minimal amounts (1-3 cups a day). Also a few patients with high tea/caffeine consumption (5- 10 cups per day) have shown no response to DCA.

There are a number of potential harmful effects of starting high dose caffeine including increased likelihood of seizures in brain tumour patients, abnormal heart rhythms, anxiety, and insomnia.

DCA and Chemotherapy
Until now, there has been no scientific evidence to support the use of DCA along with chemotherapy. For the first time in North America, Medicor and ORT are now conducting ChemoFit tests with DCA and chemo combined! What this means is eligible patients can have a sample of their own tumor analyzed to see if combinations of DCA and chemo will work, and if they will work better than chemo or DCA alone. Click here to see a sample ChemoFit test report with DCA. The accuracy of the ChemoFit test ranges from 85-99%.

We have already had some exciting results showing that DCA can, in some cases, dramatically enhance the cancer-killing effects of chemo. However, there is a possibility that DCA can antagonize chemo as well. This is similar to single agent chemo being better than combination chemo for some patients. If you are a patient who is thinking of combining DCA and chemotherapy, we recommend you review our ChemoFit web page here and discuss the test with your oncologist. We also have more detailed information for physicians here.

Malignant ascites fluid samples and malignant pleural effusion samples can now be tested with ChemoFit, eliminating the need for a biopsy in some patients.

What is the status of DCA clinical trials?
Two DCA clinical trials have begun in Alberta. One will examine the effects of DCA on a type of brain tumour (50 patients), and the other will look at patients with various cancers (35 patients). If you are in the Edmonton area, we recommend you consider enrolling in one of the clinical trials. We have no further information about these trials.

Even though we have seen conclusive evidence of DCA’s effectiveness in various cancers, Medicor believes that it is essential for DCA clinical trials to be conducted. DCA is different from other drugs that undergo clinical trials because it is not a “new” drug. It has already been used for decades in humans, and has a relatively safe profile.

This means that the trials may take less time, but may still take years. Many cancer patients cannot wait this length of time. We are hopeful that information obtained from our experiences with DCA will supplement clinical trials, and help patients and the medical community.

Can I take DCA on my own?
We are aware of many patients who are currently self-medicating with DCA. Due to the complexity of cancer and its treatment, we recommend DCA to be taken under medical supervision.


Note: With regards to cancer, DCA seems not to work with sarcomas
