Filter by:Pharmacologic inhibition of RANKL attenuates the development of mammary carcinoma and inhibits metastatic progression in multiple mouse models. In a retrospective analysis it could be demonstrated that elevated expression of RANK was found in 14.5% of patients overall, with a significant predominance in patients with hormone-receptor-negative disease. Expression of RANK was associated with a higher pathological complete response rate but with a shorter disease-free and overall survival. The ABCSG-18 study showed that adjuvant denosumab reduces clinical fractures, improves bone health, and can be administered without added toxicity. It appears therefore reasonable to test denosumab, a clinically available antibody against RANKL in patients with hormone-receptor-negative primary breast cancer as an adjunct to neoadjuvant chemotherapy for its ability to increase pCR rate and improve outcome in relation to the expression of RANK.
Two regimen are currently considered to have highest efficacy for patients with high-risk early stage breast cancer: sequential treatment of high dose epirubicin, taxane, and cyclophosphamide concomitantly with a dual HER2-blockade, and weekly treatment with paclitaxel/non-pegylated liposomal doxorubicin with dual HER2-blockade or carboplatin. The aim of the GeparOcto study is to compare those two regimen/strategies. Both regimens are myelosuppressive with a significant incidence of chemotherapy induced anaemia. The second aim of the GeparOcto study is therefore to compare the use of parental ferric carboxymaltose versus physician's choice for the treatment of chemotherapy-induced anemia in patients with iron deficiency.
Current guidelines as those from the AGO-Breast commission recommend for neoadjuvant breast cancer patients either a sequence of 4 cycles EC followed by 4 cycles of a taxane or 6 cycles of TAC based on previous large scale studies. Treatment of patients with HER2-positive disease should include also simultaneous application of trastuzumab. Solvent-based taxanes (paclitaxel, docetaxel) cause severe toxicities not only by the active agents itself but also by the solvents like cremophor. Nab-paclitaxel (Abraxane®) is a solvent-free formulation of paclitaxel encapsulated in albumin. It does not require premedication with corticosteroids or antihistamines to prevent the risk of solvent-mediated hypersensitivity reactions. This new formulation improves safety profile, allows higher dosing with shorter infusion duration, and produces higher tumor drug concentration. As neoadjuvant treatment does not only allow to compare competing treatment approaches with a very high quality (homogenous treatment population, precise assessment of response by histological assessment), but also to identify predictive markers, this trial will compare weekly nab-paclitaxel with solvent-based paclitaxel at their currently optimal doses. In case of HER2-positive tumor status patients receive Pertuzumab and Trastuzumab additionally.
Study participants with primary breast cancer will receive a standard chemotherapy with an anthracycline and a taxane as well as trastuzumab in case of HER2-positive tumors at doses and duration in concordance to current treatment guidelines. Patients will be receive and benefit in addition currently not in the neoadjuvant setting registered medication as lapatinib or bevacizumab of which significant increases of cure (pCR) rates have been reported in previous phase III studies. Patients randomized to carboplatin will receive in addition to the described backbone therapies a potentially active agent which suggested synergy of efficacy with chemotherapies as well as targeted agents. Patients might have the risk of an increase in toxicities due to the added agents and will have additional burden due to investigations required for study participation. However, due to the severity of the underlying disease and the high risk of relapse and death due to the stage of disease, this increase in toxicity and burden appears less relevant compared to the potential higher efficacy and finally cure rate by the incorporated treatments.
