ProtoKinetix Achieves Primary Objective Safety at Midpoint of Clinical Trial

Marietta, Ohio, June 7, 2019

ProtoKinetix, Incorporated (www.protokinetix.com) (the "Company" or "ProtoKinetix") (OTCQB:PKTX) today announced reaching the midpoint of a Phase-1 first-in-human clinical trial of AAGP™ PKX-001 treated islet cells used in conjunction with the Edmonton Protocol for the treatment of Type-1 diabetes. All six patients were recruited and treated under this protocol.  All primary safety objectives have been achieved at the midpoint in all study participants. As such, the protocol will now be amended to increase the number of participants in the trial with additional secondary objectives added including dose escalation to establish optimization criteria for efficacy testing. In order to satisfy the increased demand for the ongoing clinical trials and expanding research collaborations, the Company has ordered an additional 200 grams of GMP grade PKX-001 molecule. This represents the most significant scale-up of manufacturing in the Company’s history. Request for approval of the amendments will be submitted to Health Canada by the sponsor, the University of Alberta.

The trial is being led by Dr. James Shapiro, MD, PhD, FRCSC, MSM FCAHS, AHS Director of Clinical Islet and Living Donor Liver Transplant Programs, Canada Research Chair in Transplant Surgery and Regenerative Medicine, Professor of Surgery, Medicine and Surgical Oncology, University of Alberta.

About the Edmonton Protocol

"We found this anti-ageing glycopeptide (AAGP™) compound to have surprising efficacy in our preclinical testing with human islets. Working with ProtoKinetix we have been able to rapidly move forward to early pilot clinical testing in patients. Thus far, the treatment has proved to be remarkably safe, and we are now in the process of increasing the dose with the goal being to substantially improve islet engraftment and survival in our islet transplant patients. We are especially excited about this trial!" – Dr. James Shapiro

PKX-001 is the designation given to the lead drug product molecule of the AAGP™ family. Islet cell transplants are well recognized as a viable and effective treatment for Type-1 diabetes. The PKX-001 study will treat islet cells prior to transplantation into human test subjects. The clinical trials primary objective is the establishment of patient safety. The study will also be make observations related to indications of protection from tacrolimus toxicity and enhanced engraftment survival of the transplanted cells. The trial follows extensive preclinical evaluation in experimental models (to learn more, refer to this link: Diabetes).
