$PMCB PharmaCyte Biotech, Inc. (OTCQB:PMCB), a clinical stage biotechnology company focused on developing targeted treatments for cancer and diabetes using its signature live-cell encapsulation technology, Cell-in-a-Box®, today announced that it has advanced into a new and promising phase of research at the University of Northern Colorado (UNCO) in its quest to develop targeted cannabinoid-based chemotherapy utilizing the Cell-in-a-Box® technology.

"The work at UNCO is just one of the programs actively underway at PharmaCyte," commented the Chief Executive Officer of PharmaCyte, Kenneth L. Waggoner. "With our preliminary work complete, we are now looking forward to the possibility of making significant progress in the development of targeted cannabinoid-based chemotherapy. The approach being used for our cannabinoid-based chemotherapy is the same as we are using for our pancreatic cancer therapy."

Utilizing data collected from recently-completed preliminary studies, a new research protocol has been undertaken to deliver anti-cancer cannabinoid molecules like cannabidiol (CBD) and tetrahydrocannabinol (THC) to solid tumors in a targeted fashion. PharmaCyte has identified a naturally-occurring enzyme that it believes is capable of converting specific cannabinoid prodrugs into cancer-fighting forms. The exact gene code of this enzyme has been sequenced.

Knowing the gene code, it is possible to synthesize the gene. The gene may then be inserted or "transfected" into the genetic code of live human cells. The bioengineered cells may then be grown in culture and tested for their cannabinoid prodrug activating ability. This work is currently in progress. If sufficient prodrug activation is detected, PharmaCyte plans to move directly to live-cell encapsulation using its Cell-in-a-Box® platform technology and pre-clinical testing with various cancer models.

The goal is to implant encapsulated bioengineered cells at the site of a tumor and then to administer the cannabinoid prodrug into a blood vessel near the tumor. The enzyme produced by the live cells within the capsules would activate the prodrug in a targeted fashion, initiating cancer cell death. Such an approach should maximize effectiveness and minimize side effects from this form of chemotherapy.

"We are quite pleased with the progress UNCO has made and to have all the necessary components in place to advance our research," commented cannabinoid medicine expert and member of PharmaCyte's Medical and Scientific Advisory Board, Dr. Mark L. Rabe. "Having a candidate enzyme and knowing the gene behind it is huge. It is now a matter of completing a series of steps and making sure everything we have planned works. If so, it is a fairly straight line to the clinic. Our initial goal is to tackle glioblastoma, an almost untreatable form of brain cancer."

About PharmaCyte Biotech

PharmaCyte Biotech is a clinical stage biotechnology company developing therapies for cancer and diabetes based upon a proprietary cellulose-based live cell encapsulation technology known as "Cell-in-a-Box®." This technology will be used as a platform upon which therapies for several types of cancer and diabetes are being developed. PharmaCyte's therapy for cancer involves encapsulating genetically engineered human cells that convert an inactive chemotherapy drug into its active or "cancer-killing" form. These encapsulated cells are implanted as close to the patient's cancerous tumor as possible. Once implanted, a chemotherapy drug that is normally activated in the liver (ifosfamide) is given intravenously at one-third the normal dose. The ifosfamide is carried by the circulatory system to where the encapsulated cells have been implanted. When the ifosfamide comes in contact with the encapsulated cells they act as an artificial liver and activate the chemotherapy drug at the source of the cancer. This "targeted chemotherapy" has proven effective and safe to use in past clinical trials and results in no side effects.

In addition to developing a novel therapy for cancer, PharmaCyte is developing a therapy for Type 1 and insulin-dependent Type 2 diabetes. PharmaCyte plans to encapsulate a human cell line that has been genetically engineered to produce, store and release insulin in response to the levels of blood sugar in the human body. The encapsulation will be done using the Cell-in-a-Box® technology. Once the encapsulated cells are implanted in a diabetic patient they will function as a "bio-artificial pancreas" for purposes of insulin production.

$PMCB PharmaCyte Biotech Requests Pre-IND Meeting with FDA for its Pancreatic Cancer Clinical Trial
PharmaCyte Biotech, Inc. (OTCQB:PMCB), a clinical stage biotechnology company focused on developing targeted treatments for cancer and diabetes using its signature live-cell encapsulation technology, Cell-in-a-Box®, today announced that it has submitted a request for a pre-IND meeting with the U. S. Food and Drug Administration (FDA) for its planned clinical trial in locally advanced, inoperable pancreatic cancer (LAPC).

PharmaCyte has submitted questions to the FDA as part of a pre-IND meeting request where aspects of the content of the Investigational New Drug (IND) application itself (CMC section, clinical trial description, etc.) will be discussed. After the FDA has responded to the questions and issued comments, PharmaCyte must address them to the FDA’s satisfaction. A review of PharmaCyte’s responses by the FDA will then take place at the formal pre-IND meeting where final agreement between PharmaCyte and the FDA on all aspects discussed will be reached. With this information, the IND will be submitted by PharmaCyte and reviewed by the FDA. Once the IND is found to be acceptable to the FDA, patients can be enrolled in PharmaCyte’s clinical trial.

PharmaCyte’s Chief Executive Officer, Kenneth L. Waggoner, said of the meeting request, “We are pleased that PharmaCyte has taken the first step towards regulatory approval in the United States of its therapy for LAPC. When I started to lead this company in January 2014, my first goal was to surround our technology with the best of the best in the biotech sector. I believe we have more than accomplished this goal as we have compiled an internationally renowned team that will lead PharmaCyte into what we expect to be a pivotal human clinical trial. My second goal was to get our therapy to the FDA, and with this pre-IND meeting request, we have accomplished this goal as well. My ultimate goal, of course, was and is to get our pancreatic cancer therapy into clinical trials and approved by the FDA. I feel we are well on our way to accomplishing this goal.”

PharmaCyte’s clinical trial in patients with LAPC is designed to meet a clear unmet medical need for those whose cancer no longer responds after 4-6 months of treatment with the combination of Abraxane® plus gemcitabine. The trial will be open-label and multi-site in nature, with sites in the U.S. and Europe. Patients with LAPC will be randomized equally into two groups. One group will receive gemcitabine chemotherapy alone, and the other group will receive PharmaCyte’s pancreatic cancer therapy (encapsulated genetically modified live human cells that can activate the cancer prodrug ifosfamide plus low doses of the prodrug to eliminate side effects from the chemotherapy). In addition to comparing the anticancer activity and safety of the two therapies, a major aspect of the trial will be to determine if, and how well, PharmaCyte’s therapy can shrink inoperable tumors so that they become operable.

Hi K....vitamin supplements...

I like pterostilbene too.
Ive read ,maybe from Mercola, or somewhere else reputable, that latest research about Calcium ,problems, including calcium deposits in the arteries,has a lot more to do with Magnesium deficiencies....because Magnesium is the 'partner' mineral to calcium,and sometimes the calcium imbalance is more because of magnesium deficiency. that causes calcium to be leeched from the bones, etc... interesting reading. you can find it with some internet searching.
Vitamin C is good medicine when its taken in high dose, like what Linus Pauling did. working up gradually to 10 or 20 grams a day. I average 5 grams a day these days.
Centrum, ?? Karin...??! centrum is very weak.... its hardly any vitamins at all..... you could use a good vitamin coach. go to my forum if you want to have a good chat sometime.
Happy holiday to you.
