HAART Antivirals? Atorvastatin dosage?



My dad is on valtrex (valaciclovir/valacyclovir) daily and I noticed it is a guanosine analogue. I was wondering if anyone is taking HIV HAART treatment, such as tenofovir as well? It is a adenosine analogue and therefore I would imagine would work well to bind to Cytosine and Valtrex to Thymine in the cancer DNA? I would imagine antiviral drugs are limited if only 1 of 4 potential DNA base analogues is used? I know the CUSP9 protocol is using ritonavir but it is just used by itself - perhaps a cocktail of antivirals need to be used to combine with the cancer DNA?

Also we were wondering about Atorvastatin dosage as he is on 20mg a day but Care Oncology seem to recommend people are on 80mg a day? Do people get side effects on this dosage? Should we increase the dosage?

Background on my dad:
My father was diagnosed with Grade 4 GBM after a grand mal seizure 24th Feb 2019. Located in the left temporal lobe. 
He had a successful craniotomy on the 7th of March 2019

He completed the 30 sessions and then 3 months of 5/23 TMZ chemo. In September 2019, there was alot of swelling/looked like the tumor was very active by MRI and due to MGMT unmethylation the hospital stopped the TMZ and have now been giving him Avastin on Mondays every 2 weeks.  Bloods are all normal and within range.


He was having trouble with speach and twitching in September time but this is now gone and he is back to 100% after adding Phenytoin, Clobazam and Dexamethasone

Daily:
Seizure drugs: 1.5g x 2 Keppra ; Phenytoin; clobazam daily. 
He carries around Midazolam injections in case he was ever to have a seizure but has only had 2 occassions this year.
2 x 2 mg Dexamethasone daily

Experimental Drug Cocktail (Ben Williams):
1g x 2 Valtrex (valaciclovir/valacyclovir); Chloroquine (155mg active ingredient); Celebrex 200mg; metformin 500mg x 2; 20mg Atorvastatin; ramipril; ranitidine 75 mg;  melatonin 20mg; 100mg mebendazole (1 month on/1 month off); 100 mg x 2 minocycline (1 month on/1 month off);

Daily supplements of multivitamin; 16 strain Probiotics; PSK; Maitake D; ; Mushroom supplement mix for brain (lions mane 300mg; bacopa 250 mg; reishi 150 mg; gotu kola 130 mg; ginko 120 mg); curcumin (longvida); vitamin D; ECG; Milk Thistle; Berberine; Boswellia; Resveratrol; Omega 3-6-9; Soy Falvonoids (geinistein); Astragalus; Artemisinin

Antioxidant use in IDH1 mutant tumors

I'd like to open a topic up for debate here regarding antioxidant use in IDH1 mutant tumors. My understanding is that IDH1 mutant tumors are characterized by generally low Glutathione (antioxidant) levels, significantly sensitizing them to ROS generation. Some researchers speculate that this is the primary reason for superior OS stats for IDH1 mutant tumors, e.g.:


Given this particular dynamic, should I conclude that use of antioxidants which stimulate Glutathione (e.g. Alpha Lipoic Acid, Green tea, Cinnamon,...) should better be avoided in the case of IDH1 mutant tumors?

I am particularly interested in this question as my tumor is IDH1 mutated, and I recently started taking the Metabloc protocol (Alpha Lipoic Acid + Hydroxycitrate), since it seems to deliver very promising synergy with Metformin use. After investigating a bit, I am contemplating skipping the Alpha Lipoic Acid, however. 

Any thoughts on this topic? Thanks!

study on the usage of Metformin

Hi everyone,

I just found this survey that says there were no significant relation between metfomin and OS or PFS of glioblastoma patients, unlike those with grade III.

http://sci-hub.tw/10.1002/ijc.31783

What do you think? Is there still any hope that they might not consider some aspect, dosage, etc that could challenge their data? I mean, is it still logical to include it in the cocktail?

Combining DCA and metformin

New study called Influence of metformin, sodium dichloroacetate and their combination on the hematological and biochemical blood parameters of rats with gliomas C6 published in Experimental Oncology.

https://www.ncbi.nlm.nih.gov/pubmed/30284997  (pubmed abstract)

http://exp-oncology.com.ua/wp/wp-content/uploads/2018/10/2507_01.pdf?upload=   (PDF download)

 "The administration of DCA did not significantly affect the life span
of rats with C6 glioma"

Average lifespan of rats was increased by 19% with metformin alone

Combination treatment with metformin and DCA increased average lifespan of rats by 50%

"the expressed antitumor effect of combination therapy with DCA and MTF [metformin] was associated with a decrease (p < 0.05) in glucose and lactate levels in blood plasma of rats with C6 glioma by 10% and 41.4%, respectively, compared to tumor control."

"Analysis of blood parameters showed that the growth of C6 glioma was accompanied by the development of leukopenia, anemia and thrombocytopenia."

"MTF [metformin] alone and in combination with DCA positively influenced the number of white blood cells and caused complete thrombocytopenia correction, increasing platelet count by more than 200%"

Drug Cocktail for Newly Diagnosed GBM


Hi Everyone,

I'm new to the blog and blogging in general. My brother is 3 weeks post op craniotomy for removal of 2cm brain tumor in left frontal lobe - complete resection was not possible but approximately 80% removed. Otherwise Joe is a healthy 35 yo male

Pathology report came back:
Grade IV Glioblastoma, wild type
Negative IDH1/2
Negative MGMT methylation
No amplification of EGFR gene

He will be part of a clinical trial with proton therapy radiation at MGH in Boston.  Joe is gripped by depression but committed to starting treatment - hopefully along with a drug cocktail. I've been helping him research and pull it together. When he starts radiation and chemo in a week or so I would like him to be on below meds / supplements


DrugDosage
Valproic Acid1000mg
Chloroquine250mg daily
Celebrex200-400mg daily
Fluoxetine40mg daily 


SupplementDose
CBD / THCgradually increasing dose
Boshwella 1000mg
Green Tea
Curcumin1000-2000mg +
Melatonin10-20mg
Maitake D 100mg
Fish Oil
Probiotic
Turkey Tail - ie PSK 3000mg
Vitamin D35000-10,000 UI
quercetin500mg
milk thistle 1000-2000mg
Reishi mushroom

This is not a complete outline as I'm using some supplements he purchased and some meds he is already on (valproic acid).  I would love to have any suggestions or thoughts.

I also have some questions for you all (I'm sure the first of many) 

1. How open are neuro oncologist to a cocktail approach? Joe is afraid of asking them about adding anything to the current standard of care 

2. Is it true that unmethylated MGMT tumors are not as responsive to TMZ? Should we ask about a metronomic everyday low dose? What is the current dosing of TMZ in standard of care?

3. Should we look into adding Antabuse, Metformin, or an ACE Inhibitor? 

Best, 

Jenna

First results of cocktail trial (memantine, metformin, mefloquine, temozolomide)

I'll be working on a review of the latest brain tumor news coming from the ASCO conference currently underway.  Since this is the brain tumor cocktails blog, thought I'd post these results to start off.

Phase I factorial study of temozolomide plus memantine, mefloquine, and metformin as post-radiation adjuvant therapy for newly diagnosed glioblastoma.
https://meetinglibrary.asco.org/record/164026/abstract

The abstract gives maximum tolerated doses for doublet therapy (TMZ + one of the other drugs), triplet, and quadruplet combinations.

2 year survival rate for the entire trial population (all combintions) was 43%, similar to the 2-year survival seen in the EF-14 trial for the Optune + TMZ arm.

Since some of the combinations were probably more effective than others, it will be interesting to see the results when separated by treatment arm.

Need suggestions to incorporate supplements in my mom's cocktail(GBM Patient)

Hi folks,

My mother(Age 47) was diagnosed with glioblastoma(IDH1/2 -ve, Methylated) in September 2017, and it has left me devastated ever since. She has completed her 6 weeks of radiation/chemo and her first cycle of 5/23 temozolomide. Her next cycle of temozolomide starts 5 days from now. I stumbled upon this blog just a week back, and have found this to be immensely helpful and resourceful.

I need help from you guys on what else should I incorporate in my mom's cocktail. Following are the supplements that are present in her cocktail per day already:

Metformin: 500 mg
Boswellia Serratta: 4000 mg
Resveratrol: 400 mg
Fish Oil: 3600 mg DHA+EPA + 400 mg of other omega 3 fatty acids
Curcumin with piperine: 5000 mg
Longvida: 400 mg
Quercetin: 5000 mg
Melatonin: 20 mg
Selinium: 200 mcg
Vitamin ADK supplement with 5000 IU Vitamin D3
Ashwagandha: 500 mg
Garlic: 6 cloves
Ginger: 6 cloves
Dendritic cell therapy: On the cards
Cannabis oil: Dropped because it was suppressing her WBCs

She is also on ketogenic diet and has done about 2 weeks of hyperbaric oxygen. We are looking at two more weeks of hyperbaric oxygen.

I'm looking for more supplements that are good adjuvants to temozolomide/standalone good adjuvants that I should definitely include in my mom's cocktail. It'd be great if you guys could help out in more supplements that I should include, I'm finding it very hard to self medicate my mom. Basis Ben Williams' book and reading several blogs, the following supplements have repeatedly been catching my attention:

1. DCA
2. Chloroquine
3. Care oncology clinic protocol(Metformin + Doxycline + Mobendezole + Atorvastatin)
4. Ruta 6 + Calceria Phos(Not sure if it is a good idea to use while on chemo)
5. Methadone
6. Veramapil
7. Low Dose Naltrexone
8. Disulfiram
9. Perilyl Alcohol
10. Methadone
11. Celebrex

She is already taking a total of 50 meds per day and I think she can take only 10-15 more. Would be great if you can help me from above list/any other supplement that should definitely be a part of her cocktail.

Thank you in advance!

One reason mouse studies don't translate to humans

I just came across a study that looked very interesting, showing increased survival in an orthotopic glioma mouse model when metformin is combined with temozolomide.

High-Dose Metformin Plus Temozolomide Shows Increased Anti-tumor Effects in Glioblastoma In Vitro and In Vivo Compared with Monotherapy



Especially interesting was the finding that the higher dose of metformin + temozolomide eliminated the expression of fatty acid synthase in the tumor specimens.



Fatty acid synthase (FASN) may be an especially good target in IDH1-mutant gliomas, as FASN is one of the most differentially overexpressed transcripts in G-CIMP (for the most part IDH mutant) gliomas versus non G-CIMP (for the most part IDH wild-type).



As is usually the case, the devil is in the details.

The study states several times that the metformin doses used in this study are clinically relevant, and this is true, except for the fact that the mice were injected with metformin intraperitoneally, rather than fed the metformin orally the way humans would take it.

From a different study, we know that intraperitoneal injections of metformin can lead to peak plasma levels 150-fold higher than what can be achieved with oral dosing.

"Notably, HPLC-ESI-QTOF-MS pharmacokinetic analysis showed that the plasma levels of metformin immediately after the last i.p. injection were ~150-fold higher than those obtained with the oral dosing schedule. Thus, mice that were treated with the i.p. dosing schedule achieved 679 ± 16 µmol/L (~87 µg/mL) metformin, a circulating dose of metformin that is within the lower limit observed in an individual with metformin poisoning..."

Pharmacokinetic differences between the methods of drug administration used in mouse studies (often intraperitoneal) and the methods used in humans, may account for some of the failures of mouse studies to translate into clinical results.

It would be interesting to investigate the anti-diabetes drug phenformin, a much more potent biguanide which was removed from the market in the 1970s due to increased risk of lactic acidosis, for cancer treatment.

Metformin in vivo, C6 glioma - Wistar rat model

This is the first study I've seen testing metformin in an orthotopic glioma model with oral (rather than intraperitoneal) administration.  The survival gain was modest, but threre was a gain nonetheless.

Metformin's Debilitating Side Effects

My sister stopped taking metformin as she could not tolerate its side effects. She complained from severe nausea, dizziness, and fatigue. Anyone knows some tricks to overcome this problem?

She currently is on Temodar, Keppra, Vitamin D3, Curcumin, and Memantine. 

Thank you.

Effects of metformin treatment on glioma-induced brain edema

http://www.ajtr.org/files/ajtr0024896.pdf

"Finally, metformin treatment dose-dependently reduced glioma induced vascular permeability and cerebral edema in vivo in rats. Thus, our results suggested that metformin may protect endothelial cell tight junction, prevent damage to the blood brain barrier induced by brain tumor growth, and alleviate the formation of cerebral edema."

The rats were fed metformin dissolved in their daily drinking water.

Metformin

Can you take metformin if you are unable to eat properly for GBM recurrence?

My daughter's recurrence means she is now stuck in bed can't swallow much.
I am trying to think of what medications would be best to try to get her to take if she can't eat much or swallow very easily?
I can't just leave her without meds to deteriorate even more.

Gbm from egypt Update

Dear all..
I am Sarah wife of Ahmad
I am not a very good follower of this blog as I used to be with the old one as I dnt get email notifications as I did..I know I's a simple issue so pls I give me a tip for that..

I posted Ahmad's cocktail earlier
He is on ccnu we are going to take our fourth round in 10 days..

With the ccnu he is taking:
Tamoxifen
clorocquine
Ppis
Accutane
Verapamil on chemo days

A cocktail so much like what Ben did..
Together with all the common supplements
Every one here is probably taking..
Our state:
We do struggle with our seizures..Ahmad is taking now 3000mg keppra divided twice daily and 1800 mg trileptal also divided..
I can not say that his seizures are fully controlled..a week ago he missed a dose and got 7 seizures in one night..
Right now he can get a really minor seizure just before the time of his medicine sometimes..I hope it gets better..and I have no idea why his seizures are that persistant..

His last MRI showed that the "spot" I sent u about earlier is not growing which is good news but still close monitoring is needed ..

There is also some short term memory problems and sometime problems in the ability of expression But not noticed..

Approaching our 4th round now and he began to feel very weak..he is nauseated all the time and always wants to sleep..this didn't happen before especially that we are away from ccnu last dose..is this normal??
If anyone have similar experience pls share..he can not take his cocktail when he is that weak..and nauseated and almost doesn't eat..

Ahmad is also on ketogenic diet..he was doing fine but now with the weakness and nausea I am thinking maybe he stops this diet and follow a less restricted one..and probably add 1500 mg metformin..what do you think?? Can he begin taking metformin while he is still on ketogenic diet??

Thank you all and I really hope you are all okay
Sarah

Matjaz's cocktail - grade 2 Oligodendroglioma


Hello all!


Ok, so here is my cocktail and a little backstory:


because of mild headaches at back of the head/in the neck that started in February 2015 I was sent to MRI (neurologist was suspecting some kind of vertebrae deformation) in May 2015. It unexpectedly showed tumor in right temporal lobe (premotor cortex, some of it in insula) - while I was waiting to get the MRI the headaches went away, so it was kinda incindental discovery.


Underwent awake surgery with 100% resection with small safety margin of healthy tissue around the tumor. Tumor volume around 8,5 cm^3, pathology showed "grade 2 oligodendroglioma, IDH mutated, cells do not express GFAP , Neu N, internexin a and p53. The expression of ATRX is retained. Absence of overexpression of cMet . The Ki67 proliferation index is estimated at 1%. 1p/19q codeletion and no EGFR overexpression"

Surgery and following MRIs:

1st December 2015 - Complete Resection which is also confirmed with MRI ~30 hours after surgery
March 2016 - Clear MRI, small area of scar tissue
September 2016 - No change


My cocktail (for long term maintenance) at the moment is:

5x 600mg Mushroom Science Coriolus Super Strength
1x 4,5mg LDN
1x 5000 IU Vitamin D3
2x 850mg Metformin

4x 500mg Nutrivene Longvida Curcumin
2x 1000mg Super Omega 3

1x 200 mcg Selenium
1x 10mg Melatonin
17 mg/kg/day DCA (discontinued for 6 months or so because of  neurotoxicity - on Visual Evoked Potentials exam there was significantly lower nerve conductivity as should be, probably because of ~9 months DCA administration).


The post is updated regularly after every MRI (every 6 months for now). Also I am verry happy to receive any suggestions or answer any questions!

Best regards,
Matjaz

Metformin and autophagy

Steven

I was doing a bit of information gathering on AMPK activators, of which metformin is one, and came across information that  metformin is an mTOR inhibitor and and autophagy inducer.  The autophagy inducer information I found interesting.  Any idea how potent this action is and whether it mitigates autophagy inhibition by chloroquine?

Looking for advice to get cocktail started for my mom with recurrent GBM

Hi everyone. First off thank you all for your thoughts, information and advice. You guys keep hope alive. I'm here to try and figure out what else we (my sister, brother and I) could be doing for my mom.

I'm hesitant to make this post because I do not know the make up of my moms tumor(s) however, I do know that we need to do more for her now, before it's too late. I can try to get the pathology report from UCLA and post more on that when I do. I couldn't tell you what methylated or IDH-mutated mean but I do know my moms situation seems to be getting worse.

Without a pathology report I will try to give a brief backstory so you get a picture of what's going on here. I hope this is the right place for this and I will try to keep it as brief as possible. 

Jan 2008: Ended up scraping off side mirror on the car and realized peripheral vision was gone. Eyes checked, no problem. MRI showed brain tumor. Surgery Jan 11, 2008 at UCLA with Dr. Daniel Kelly (Now at St. Johns Santa Monica) with complete (or as close to complete) resection as possible. Diagnosed at age 51 with Stage 4 GBM and received all the scary statistics about her being lucky to make it a year. She bounced right back from the surgery as if nothing every happened. Up and about within a day or so back to her normal routine. 2 years of Temedor 5 days out of the month and around 60 rounds of radiation later, life was good and stable MRI's became the norm although every MRI was never any less scary awaiting results. We thought perhaps she was in the clear. Her vision also came back :)

My dad, her caretaker passed away unexpectedly in June 2012. I only bring this up because I believe stress may have played a big factor in the next update.

Jan 2013 MRI was clear. In fact, we celebrated 5 years remission. She then missed a scan in Feb '13 due to an insurance mix up, and finally had a scan in March '13 which showed a pea sized recurrence in the original tumor location. Prior to this she was doing so well that the doctor was going to allow her to get MRI scans less often. She was off Temodar for 3 years before this recurrence. So she went right back to several more radiation treatments and another year of Temodar (one week each month) and MRI scans monthly. Her scans showed the tumor to be shrunken and the site to be stable with no new growth.  

March 2015 MRI showed new but small growth in a new location close to the original tumor site but a bit deeper in. Oncologist tried new chemo, CCNU and were to follow up in one month. We were told she has had her lifetime max of radiation so that was out. Next scan showed the Tumor almost tripled in size. Options were try another chemo, surgery if the Tumor Board deemed it appropriate and a clinical trial going on at UCLA, Toca 511 where they inject a virus into the tumor cavity directly after resection. The remaining virus was to infuse itself in remaining cancer cells later to be killed by pills she took. We got word that surgery was an option and were able to enroll in the clinical trial. Surgery was performed at UCLA on May 14th, 2015 with Dr. Linda Liau. MRI before surgery showed more growth. Surgery was as successful as possible and Dr. Liau was somewhat surprised as she said so much of the tumor she pulled out was "dead." My mom had more trouble recovering from this operation. Memory loss for a few days, permanent vision loss and basically a big blow to her spirits because she didn't bounce back. She was still very much interested in recovery and getting stronger. As part of the study every 6 weeks she got an MRI and she took pills that were I guess anti-fungal in nature however, they were to head to the implanted virus, that had infused itself in remaining tumor cells and form a chemotherapy to destroy left over cancer cells. My mom began recovering, walking more normal and getting back to normal life minus navigating differently due to a permanent visual field cut from surgery. 

Things were looking great until October 8th 2015 when a scan showed some "changes." We were told it was nothing to be concerned of yet and that they weren't sure what was going on actually. Not the most comforting news. We were to follow up in a month or sooner if things got worse. My mom began to walk more poorly (always veering to the left) and crashing into walls, her memory became worse, most scary she just started acting odd like throwing away her fork and knife and looking for things around the house that were in completely different areas like the telephone for instance. She is aware that she is getting worse and is depressed and spends most of her awake hours crying. (We saw my grandma die from a metastatic brain tumor from lung cancer and it was not pretty) We tried to get my mom in for a scan, this time they wanted to do a DOPA-PET scan, which we were told might be the future of monitoring brain tumors. Insurance went back and forth for around 2 weeks on approving and denying and then approving only to have UCLA "run out of the DOPA injection dye."

This brings us to now. Nov 3, 2015 new scan shows growth and not just one area. The larger area is the one that appears to be messing up her walking. Our oncologist stated there looked to be a lot of inflammation around the area along with necrosis. He states that surgery on that area is probably not an option and may do more damage than good. We will seek a second opinion of course.

Nov 3, 2015 she had an Avastin infusion and was put back on Temodar 5x per mo. The Toca 511 trial has been put on hold. Her spirits are destroyed.

Throughout the course of this she has taken many supplements (mostly the first few years) Lots of different mushroom powders and something called Ave, some type of wheat germ for boosting her immune system. March of this year she started the CBD/THC Cannabis oil off and on. She can't stand feeling "high."

As of now she's taking:
Temodar 
Avastin 
Keppra 750mg 2x daily 
AHCC mushroom supplements. 

She was taking Wellbutrin but I'm not sure how consistent she is. 

It's probably too early to tell if the new drugs have done anything however, prior to them we were seeing a steady decline. Since getting them a few days ago she at least doesn't appear to be any worse symptom wise. 

We were told if she responds to treatment, great. If not she could be gone in a few months. I'm hoping this could at least buy us some time to get her back on the right track. 

So, what would you guys recommend we add in immediately along with her Avastin and Temodar? 


I'm sorry this is long and thank you. If someone would like to email or talk on the phone I'm sure that could be arranged.

Metformin and temozolomide act synergistically

Metformin and temozolomide act synergistically to inhibit growth of glioma cells and glioma stem cells in vitro and in vivo  (click on this link)

Unfortunately this was another flank-injected, non-orthotopic mouse model, and used an overly high metformin dose of 400 mg/kg mouse body weight.  The mice were immunodeficient SCID mice.  Still, most of us here are using metformin anyway, so this is additional encouragement.  See especially figure 7A on page 10.

Metformin for Low Grade Maintenance or Not?

I have residual, yet stable low grade oligodendroglioma. I'm trying to decide whether Metformin is worth taking or whether it could potentially contribute to a resistant mutation in the future. I've looked for some research but can't find any. Anyone have a theory on this?
