ACNU-Based Chemotherapy for Recurrent Glioma in the Temozolomide Era
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2009 ACNU-based chemotherapy for recurrent glioma in the temozolomide era Happold, C Abstract: No standard of care for patients with recurrent glioblastoma has been defined since temo- zolomide has become the treatment of choice for patients with newly diagnosed glioblastoma. This has renewed interest in the use of nitrosourea-based regimens for patients with progressive or recurrent dis- ease. The most commonly used regimens are carmustine (BCNU) monotherapy or lomustine (CCNU) combined with procarbazine and vincristine (PCV). Here we report our institutional experience with nimustine (ACNU) alone (n = 14) or in combination with other agents (n = 18) in 32 patients with glioblastoma treated previously with temozolomide. There were no complete and two partial responses. The progression-free survival (PFS) rate at 6 months was 20% and the survival rate at 12 months 26%. Grade III or IV hematological toxicity was observed in 50% of all patients and led to interruption of treatment in 13% of patients. Non-hematological toxicity was moderate to severe and led to interruption of treatment in 9% of patients. Thus, in this cohort of patients pretreated with temozolomide, ACNU failed to induce a substantial stabilization of disease in recurrent glioblastoma, but caused a notable hematotoxicity. This study does not commend ACNU as a therapy of first choice for patients with recurrent glioblastomas pretreated with temozolomide.

Intravenous Ascorbate and Oncologic Agents
© PAUL S. ANDERSON 2013 INTRAVENOUS ASCORBATE AND ONCOLOGIC AGENTS Updated Data Review and Policies for concurrent use at Anderson Medical Specialty Associates, Southwest College of Naturopathic Medicine Research Institute and Medical Center and Bastyr University Clinical Research Center Paul S. Anderson 05/01/2013 © Paul S. Anderson – All rights reserved – Reproduction and redistribution only allowed with proper attribution. Abstract: Intravenous application of ascorbic acid (IVAA) has a long history in adjunctive oncology communities. Its use has stimulated much debate regarding efficacy, safety and appropriate inclusion in oncologic practice. The potential for both antagonistic and synergistic interactions between IVAA and chemotherapies or radiation has existed for some time as an unanswered or confusing question in the naturopathic and allopathic oncology community. The purpose of this publication is to summarize and update the state of understanding of this complicated topic for clinicians employing either standard or integrative oncology care. INTRAVENOUS ASCORBATE AND ONCOLOGIC AGENTS Introduction: Intravenous ascorbate has been used in oncology practice by naturopathic and alternative allopathic physicians for decades. Published data regarding this therapy shows that it continues to be one of the most commonly employed alternative IV therapies. This popularity has both stimulated awareness of this therapy and concern regarding not only the safety and efficacy of IVAA in the oncology patient but also for the potential of antagonistic -

Methods Participants were stratified by IELSG risk score (low versus intermediate versus high) and randomly assigned (1:1) to receive four cycles of FTD or HD-MA regimen. Both regimens were administered every 3 weeks and were followed by whole-brain radiotherapy. The primary endpoints were overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). Results Between June 2012, and June 2015, 52 patients were enrolled, of whom 49 patients were randomly assigned and analyzed. Of the 49 eligible patients, no significant difference was observed in terms of ORR between FTD (n = 24) and HD-MA (n = 25) groups (88% versus 84%, respectively, P = 0.628). Neither the 2-year PFS nor the 3-year OS rate differed significantly between FTD and HD-MA groups (37% versus 39% for 2-year PFS, P = 0.984; 51% versus 46% for 3-year OS, P = 0.509; respectively). -

À2 À2 Clinical Studies cisplatin, 1000 mg m i.v. gemcitabine, and 2500 mg m i.v. treosulfan on days 1 and 8. Cisplatin, gemcitabine, and treosulfan therapy was repeated every 5 weeks until progression of disease occurred. A maximum of 11 CGT cycles (mean, two cycles) was administered per patient. Four patients (4%) showed a partial response; 15 (17%) patients had stable disease; and 72 (79%) patients progressed upon first re-evaluation. Overall survival of all 91 patients was 6 months (2-year survival rate, 7%). Patients with partial remission or stable disease exhibited a median overall survival of 11 months (2-year survival rate, 36%), while patients with disease progression upon first re-evaluation had a median overall survival of 5 months (2-year survival rate, 0%). Treatment with CGT was efficient in one-fifth of the pretreated relapsed stage IV melanoma patients achieving disease stabilisation or partial remission with prolonged but limited survival. -

Received: 18 June 2020; Accepted: 8 July 2020; Published: 9 July 2020 Abstract: The interaction of temozolomide (TMZ) (the main chemotherapeutic agent for brain tumors) with blood components has not been studied at the molecular level to date, even though such information is essential in the design of dosage forms for optimal therapy. This work explores the binding of TMZ to human serum albumin (HSA) and alpha-1-acid glycoprotein (AGP), as well as to blood cell-mimicking membrane systems. Absorption and fluorescence experiments with model membranes indicate that TMZ does not penetrate into the lipid bilayer, but binds to the membrane surface with very low affinity. Fluorescence experiments performed with the plasma proteins suggest that in human plasma, most of the bound TMZ is attached to HSA rather than to AGP. This interaction is moderate and likely mediated by hydrogen-bonding and hydrophobic forces, which increase the hydrolytic stability of the drug. -
