Treatment Protocol

The Active Cancer Treatment Protocol

For people with active cancer. Evidence-ranked repurposed drugs, metabolic interventions, and adjunctive therapies to use alongside standard treatment. Not a replacement for oncology care.

This is not a substitute for standard cancer treatment. This protocol is designed to complement surgery, chemotherapy, radiation, and immunotherapy, not replace them. Every intervention here should be discussed with your oncologist. Drug interactions matter, especially with chemotherapy.

The Strategy

Active cancer requires a multi-target approach. This protocol hits cancer through four simultaneous angles: direct cancer cell killing (repurposed drugs that disrupt cell division), metabolic starvation (ketogenic diet cuts off glucose, cancer's primary fuel), oxidative stress (IV vitamin C generates hydrogen peroxide in tumors), and immune support (melatonin, vitamin D, sleep). No single intervention is enough. The combination creates multiple points of failure for cancer cells.

Tier 1: Strongest Evidence (Grade A)

These have randomized controlled trial data showing benefit in cancer patients.

High-Dose IV Vitamin C (1.0-1.5 g/kg, 2-3x/week)

Grade A: Strong Evidence

The most evidence-backed repurposed cancer treatment. University of Iowa Phase II RCT doubled overall survival in metastatic pancreatic cancer when added to chemotherapy. Works by generating hydrogen peroxide in tumor tissue through Fenton chemistry. Cancer cells are selectively vulnerable because they have low catalase and high intracellular iron. Also inhibits HIF-1a, boosts immune function, and may reverse epithelial-mesenchymal transition.

Critical: Screen for G6PD deficiency before starting (simple blood test). G6PD deficiency can cause life-threatening hemolytic crisis with high-dose vitamin C. Typical infusion: 75-100g over 1.5-3 hours. Cost: $100-250 per infusion.

Tier 2: Promising (Grade B)

Human clinical trial data exists but is more limited. Strong mechanistic rationale.

Mebendazole 500mg twice daily (continuous)

🔬 Grade B: Promising

FDA-approved antiparasitic with Phase I/II trial data in glioblastoma and colorectal cancer. Disrupts microtubule polymerization (same mechanism as taxane chemo drugs), inhibits Hedgehog pathway, blocks VEGF (anti-angiogenic), and crosses the blood-brain barrier. The treatment dose (500mg 2x/day) is higher than the prevention dose. Must take with fatty food or absorption drops significantly.

Monitor: Liver enzymes at treatment doses, especially if combining with chemo. Bile duct cancer patients should be particularly careful given existing liver stress.

Ketogenic Diet (Calorically Restricted)

🔬 Grade B: Promising

Cancer cells are glucose-dependent (Warburg effect). That is what PET scans detect: radioactive glucose concentrating in tumors. A ketogenic diet keeps blood glucose low and ketones elevated. Normal cells adapt to burning ketones. Cancer cells with damaged mitochondria cannot efficiently use ketones, creating differential metabolic stress. The Press-Pulse Protocol (Seyfried, Boston College) takes this further by also targeting glutamine, cancer's second fuel source.

Protocol: Restrict carbohydrates to under 30g/day. Moderate protein (0.8-1.2g/kg). High healthy fats. Aim for blood glucose under 70 mg/dL and ketones over 2.0 mmol/L. Consider 20-30% calorie restriction if weight allows. Extended fasts (3-5 days) can amplify the metabolic stress periodically.

Disulfiram 250mg + Copper Gluconate 2mg (daily)

🔬 Grade B: Promising

Antabuse, the alcoholism drug. Kills cancer stem cells through cuproptosis (copper-dependent cell death). Reverses multidrug resistance by inhibiting NF-kB. JAMA Network Open RCT in glioblastoma confirmed safety with concurrent temozolomide. Must be taken with copper to work against cancer. Absolute alcohol avoidance required (severe reaction).

Tier 3: Early Evidence (Grade C)

Strong preclinical data but limited or no human cancer trial data. Use as adjuncts, not standalone.

Ivermectin (dose varies)

🔶 Grade C: Early / Limited

Impressive preclinical breadth: inhibits Wnt/beta-catenin, PI3K/Akt/mTOR, PAK1, and STAT3. Kills cancer stem cells (rare property). Reverses multidrug resistance by inhibiting P-glycoprotein. Strongest breast cancer data (especially triple-negative). The problem: anticancer concentrations in test tubes (5-20 micromolar) may not be achievable at safe human doses. No completed cancer-specific clinical trials.

Anecdotal protocols: 1mg/kg daily or every other day (5x the standard antiparasitic dose). Safety at this level is unestablished for cancer use. CYP3A4 substrate, many drug interactions possible.

Fenbendazole 222mg (1g Panacur C) 4 days on / 3 days off

🔶 Grade C: Early / Limited

The "Joe Tippens Protocol." Real mechanism (microtubule disruption) but zero human clinical trials. Tippens was simultaneously on Keytruda immunotherapy, making it impossible to credit fenben alone. Veterinary drug with no human safety data at anticancer doses. If you want a benzimidazole, mebendazole is the evidence-based choice: FDA-approved, human trial data, known safety profile.

Itraconazole (dose varies by cancer type)

🔶 Grade C: Early / Limited

Antifungal with Hedgehog pathway inhibition and anti-angiogenic properties. Phase II data in prostate cancer. Reverses drug resistance. Generally well-tolerated but watch for liver toxicity and drug interactions (potent CYP3A4 inhibitor).

Supportive Base (Daily)

These carry over from the prevention protocol and apply equally during active treatment.

Melatonin 20mg at bedtime

🔬 Grade B: Promising

At treatment doses, melatonin has direct anticancer activity: inhibits proliferation, induces apoptosis, and enhances immune surveillance. Meta-analysis of 8 RCTs: 34% reduction in one-year cancer mortality. Also improves sleep quality during chemo. Safe at high doses. Start at 5mg and work up.

Vitamin D3 5000 IU + K2 200mcg

🔬 Grade B: Promising

Higher dose than prevention protocol. VITAL trial showed 25% reduction in cancer mortality. Low vitamin D is associated with worse outcomes across most cancer types. Target serum level: 60-80 ng/mL during active treatment (vs. 50-60 for prevention). Monitor levels quarterly.

Omega-3: 3g EPA+DHA

🔬 Grade B: Promising

Higher dose during treatment. Reduces inflammation, may reduce chemotherapy-induced peripheral neuropathy, and supports immune function. VITAL trial: 40% reduction in fatal cancer.

Fasting 13+ hours overnight

🔬 Grade B: Promising

Suppresses IGF-1, activates autophagy. Some evidence that fasting before chemotherapy reduces side effects and enhances efficacy (differential stress resistance). Do not fast during chemo without oncologist approval if experiencing significant weight loss.

Common Combinations

How people typically stack these. These are from clinical trial protocols and published research, not random internet forums.

With Chemotherapy

IV Vitamin C 2-3x/week + mebendazole 500mg 2x/day + ketogenic diet + melatonin 20mg. This is the strongest evidence-based stack. The Iowa trial used IVC + chemo. Mebendazole has RCT data alongside chemo. Ketogenic diet has case reports with chemo. Melatonin has RCT data alongside chemo.

Without Chemotherapy (or between rounds)

Mebendazole 500mg 2x/day + ivermectin (anecdotal: 1mg/kg every other day) + ketogenic diet + extended fasts 3-5 days monthly. This is less evidence-backed but has the strongest preclinical rationale. The combination of mebendazole (microtubule disruption) + ivermectin (cancer stem cell targeting, drug resistance reversal) targets different vulnerabilities simultaneously. Track progress with regular imaging.

What to Track

Imaging (most important)

CT/MRI every 6-8 weeks initially. This is the only way to know if what you are doing is working. Tumor markers (CEA, CA 19-9, etc.) are useful supplements but imaging is ground truth.

Labs (monthly)

Liver panel (especially on mebendazole), complete blood count, metabolic panel, vitamin D level, fasting glucose and ketones, IGF-1, hsCRP. These tell you if the protocol is stressing your body or the cancer.
