Helix BioPharma Corp. (Aurora, ON) has commenced patient screening for the sixth dose level cohort in its ongoing Phase 1/2 clinical study of LDOS47 in Poland. This follows completion of the first treatment cycle of the three patients enrolled in the fifth dose level cohort, in which L-DOS47 therapy was well tolerated as reviewed by the trial steering committee. The study is an open-label study to evaluate the safety, tolerability and preliminary efficacy of ascending doses of L-DOS47, initially as a monotherapy, in patients with inoperable, locally advanced, recurrent or metastatic, non-squamous, stage IIIb/IV NSCLC. The study commenced with a starting dose of 0.12 micrograms of L-DOS47 per kilogram of patient body weight in the first patient cohort. Patients to be enrolled in the sixth cohort will receive the next L-DOS47 dose level as planned in the study protocol, which is 0.78 micrograms of L-DOS47 per kilogram of patient body weight. Qu Biologics Inc. (Vancouver, BC) has been granted its second broad Australian patent for the targeted treatment of various cancers, including all common cancers. Australian Patent No.2007308721 involves the tissue-targeted activation of the immune response to treat cancers. The patent encompasses formulations of killed viruses to stimulate this site specific anti-tumour immune response. Qu Biologics develops immunotherapies called Site Specific Immunomodulators (SSIs), which are derived from inactivated bacteria and viruses aimed at stimulating the body’s own immune system against cancer and autoimmune disease. The company’s SSI platform represents a promising new approach to cancer and autoimmune disease. Qu Biologics has developed multiple SSIs, each of which targets a specific tissue/organ system.
