Biotest starts combination therapy study with BT-062 in multiple myeloma
Whereas treatment of 32 patients within the first monotherapy study 969 is finished, Biotest continues to investigate BT-062 as monotherapy in study 975. In study 975 about 50 patients with relapsed or relapsed/refractory multiple will be treated at a more frequent dose schedule, receiving intravenous administration of BT-062 on days 1, 8, and 15 every 4 weeks. The patient recruitment of the first seven dose levels has been completed. So far BT-062 continued to be well tolerated. In addition, initial evidence of efficacy was confirmed.
Combination therapies are widely used to treat multiple myeloma and other cancers to improve overall response rates. Preclinical studies using in vitro and in vivo animal models show a strong increase of efficacy when BT-062 is combined with widely used multiple myeloma drugs such as lenalidomide, suggesting an additive or even synergistic anti-tumor effect of such combinations in patients.
Currently, Biotest expands the clinical development of BT-062 into combination therapy. The phase I/IIa study (study no. 983) investigates safety and efficacy of BT-062 when administered on days 1, 8, and 15 every 4 weeks in combination with lenalidomide and dexamethasone in patients with relapsed or relapsed/refractory multiple myeloma.A few days ago the first patient in study 983 started treatment.
Additionally, Biotest will receive funding to evaluate BT-062 in preclinical solid tumor models by the center of excellence cluster CI3 Rhein-Main 'Individualized ImmuneIntervention'. CI3 is a cluster initiative of more than 100 partners of universities, biotechnology start-ups and pharmaceutical industry, which is supported by the German Federal Ministry of Education and Research.
Biotest will continue to focus its resources on the development of BT-062 in the lead indication multiple myeloma. For further clinical development in solid tumor indications Biotest intends to collaborate with a strategic partner.
