Operational Highlights of the First Quarter

Share purchase plan "shortfall" placementProceeds of approximately A$6.8 million were received during July and August 2013 as a result of share purchase plan "shortfall" placements to sophisticated investors.

CAN-003 analysis and the ovarian cancer clinical research program. On September 18, 2013, Prima reported top-line analysis of the CAN-003 phase 2 study evaluating the effects of CVac, as compared to an observation-only control arm, in epithelial ovarian cancer patients in complete remission after first or second line treatment. Prima's management delivered a presentation of the top-line analysis via webcast and teleconference on October 2.

As advised, Prima will continue monitoring patients from the CAN-003 trial for overall survival data. It is expected that this data will be mature enough for evaluation by approximately the end of calendar year 2014. Further detailed analysis of immune monitoring is ongoing.

To date, the intracellular cytokine staining data indicate that CVac increases T cell activity directed at mucin 1. Prima believes that stimulating mucin 1-specific T cells will result in clinical benefit for ovarian cancer patients. A strong trend of improved progression-free survival in second remission patients was observed; although in the combined data of all patients on the trial, there was no observed PFS improvement.

CAN-004 ("CANVAS") clinical trial. Because the phase 2/3 CANVAS trial was designed to evaluate progression-free survival as the primary endpoint, Prima suspended enrollment of new patients on to this trial as of September 18. As of that time, 113 patients had been screened at 34 sites in seven countries. Of those patients, 76 patients had met all study criteria, had been randomized, and are in various stages of their first-line treatment. According to the trial design, patients should complete first-line therapy and achieve complete remission prior to entering the dosing stage of the trial. Thirteen patients have completed their first-line therapy and moved on to the dosing part of the CANVAS trial.

Termination of Oncothyreon Inc. License. As of October 2, Prima and Oncothyreon Inc. (previously Biomira, Inc.) agreed to terminate a License and Development Agreement, and all subsequent amendments thereto (collectively "Agreements"), related to a purported license of mucin 1 technology for use in CVac. The now terminated Agreements could have been construed as requiring Prima to pay up to US$8.5 million in research milestones and continued royalties on commercial sales of CVac. The termination clarifies that Prima has no ongoing obligations to Oncothyreon Inc.

In the event that CVac would be approved for sale in the United States prior to 2018, when certain patents related to mucin 1 controlled by Oncothyreon Inc. expire, Prima may need to obtain a license from Oncothyreon Inc. related to use of mucin 1. Mucin 1 patents expire in Canada in 2014 and are already expired in all other countries.
