Melbourne, Australia; 14 January, 2013: Patrys Limited (ASX: PAB; “the Company”), a clinical stage
biopharmaceutical company, is pleased to announce that it has received approval to progress its
Phase I/IIa PAT-SM6 multiple myeloma trial based on safety data from its first group of patients.
The first group of three patients was treated in the Department of Haematology and Oncology,
University Hospital of Würzburg, Germany. Each patient in this group received four doses of Patrys’
lead antibody PAT-SM6, at a dose level of 0.3 mg/kg.
No significant adverse events were reported from the patient group. Accordingly, the independent
board monitoring the trial has given approval for the trial to progress to the second patient group.
Full data from this first cohort will be available in the first quarter of 2013.
The recruitment of the second group of three patients has commenced. Each of the patients in the
second group will initially receive four doses of PAT-SM6, at a dose level of 1 mg/kg.
Professor Max Topp and Dr. Leo Rasche, both from the University Hospital of Würzburg, are
responsible for recruiting and treating patients in the trial. The specialist clinic is headed by
Professor Dr. Hermann Einsele who is also a Member of the Medical Advisory Board for the European
Network of Myeloma Patient Groups, a non-profit network organisation of multiple myeloma patient
groups dedicated to raising the awareness of multiple myeloma.
The trial is an open-label multi dose escalation trial in relapsed and multi-resistant patients with
multiple myeloma who have failed all currently marketed drugs and have a very poor prognosis.
Initially, twelve patients will be enrolled in four dosing groups and will receive a minimum of two
cycles (four doses) of treatment. If a patient shows a partial response to treatment with PAT-SM6 an
additional cycle (two doses) of treatment will be offered. The primary objective of the study is to
evaluate the safety and tolerability of escalating doses of PAT-SM6 and the secondary objective is to
measure efficacy as determined by a series of well-established laboratory assays. As the trial is an
open-label multi dose escalation study data will be released on an ongoing basis.
Patrys CEO, Dr. Marie Roskrow, said: “We are delighted that having received this approval we are
now able to move into the second cohort. We will be releasing full data in respect of this first cohort
as soon as possible.”

About Patrys Limited:
Based in Melbourne, Australia, Patrys (ASX: PAB) is focused on the development of natural human antibody
therapies for cancer. More information can be found at www.patrys.com.
The natural human antibody PAT-SM6 has been shown to have potent anti-cancer properties in a large number
of laboratory and animal studies. More specifically, Patrys has now screened PAT-SM6 against more than 200
tumours from individual patients with various cancers, and the product binds to over 90% of the tumours
screened regardless of cancer type or patient age, gender or disease stage. With respect to multiple myeloma
PAT-SM6 has shown particularly strong promise. Patrys has filed patent applications to cover the PAT-SM6
antibody molecule, disease target, and the mechanism of action. Patrys has successfully completed a Phase I
clinical trial to evaluate PAT-SM6 as a therapy for melanoma.
About Multiple Myeloma:
Multiple myeloma is a type of bone marrow cancer arising from plasma cells, and new therapies are desperately
needed to treat patients who become resistant to established chemotherapeutics. There is an estimated
200,000 cases worldwide and the incidence is increasing. The five-year survival of patients is approximately
30% (at 10 years ~20%). Despite new marketed therapies, multiple myeloma remains largely incurable and
fatal. The multiple myeloma market is dominated by three major products: Revlimid, Velcade and Thalidomide
with combined net sales greater than US$3 Billion in 2010.
