January 25—Administrative Core. Only Project leaders involved. Discussion included budget and possible additional nursing or research personnel.

February 1—break

February 8—Biomarkers core. Garry Buettner discussed mechanisms and resources available to all P01 members for measuring redox metabolism and measurement of ascorbate levels in all of the clinical trials.

February 15—Clinical trials core. Discussion need for blood draws and measurement of GSH/GSSG in blood and serum in the clinical trials. In addition, correlation with ROS measurements with PET scans. Project 2 clinical trial creatinine levels and re-evaluation of the protocol. Discussion centered on current accrual in all the clinical trials for Projects 1-3.

February 22—Project 2. NAMPT inhibitors combined with standard of care chemotherapy in NSCLC. Repurposing Disulfiram and copper metabolism in cancer. FLASH radiation changes in metabolism.

March 1—Project 1. Discussed different approaches to investigate P-AscH- inhibition of metastatic disease in pancreatic cancer. Discussed recent data demonstrating P-AscH- pretreatment vs. posttreatment, following splenic injections.

March 8—Discussion of clinical trials and BEACON in the electronic medical record.

March 15—start of spring break

March 22—Spring break

March 29—Project 3. MRI based T2* mapping in orthotopic murine gliomas as a method of probing iron metabolism in vivo. T2* mapping in patients receiving P-AscH and chemoradiation for glioblastomas.

April 5—Discussed dose modification for PACMAN 2.1 regarding dosing of gemcitabine + Abraxane.

April 19—Clinical trials Core C update. Discussion of xACT lung trial and use of PET CT scan in demonstrating metastatic disease. Already have 7 patients enrolled in this trial. Current accruals were examined. All trials are accruing at an acceptable rate except for PACMAN 2.1. This trial has enrolled 2 and should be at 7.5. Discussed ways to increase accrual including adding Henry Ford and Penn State as enrolling sites. The two new sites will be under the University of Iowa IRB which is a first for the UI.  Discuss Dan Xi email. “As we discussed in Dec web meeting, if you need additional funds to screen additional molecular signatures of the tumor or treatment, e.g. Kras/Braf , IDH1 or epigenome, please write the budget request and justification.  I will try to make the request from NCI for the possibility of adding additional funds.”

April 26—No meeting due to out of town absences

May 3—Doug Spitz speaking about Flash irradiation. Potential benefits due to fundamental metabolism between normal and tumor cells.

May 10—Discussed date and program for external advisers in the fall.

May 31–Discussion of lente virus transfected cell lines (small cell lung, pancreatic, lung and brain with mitochondrial-targeted catalase, light and heavy ferritin) and the design of a mouse experiment combining ascorbate with small molecule superoxide scavenger GC, in small cell lung cancer.

June 7—Project 3, Allen group. T2* mapping of orthotopic mouse gliomas as an in vivo method of probing tumor iron metabolism. Announced and discussed external advisors meeting will be October 30-31 which includes Dr. Wicha (University of Michigan) and Dr. Hauer-Jensen (University of Arkansas).

June 14—Discussion of budget and renewal and progress report for the P01. Also discussed plans for the external advisor meeting.

June 28—Presentation by new Immunology group and immunology core in the Cancer Center. Presentation of immunological studies (CD8 t cells) in lung cancer patients (xACT lung cancer trial, Project 2) receiving pharmacological ascorbate. Discussion of amendments to protocols, specifically at other sites other than UIHC.
