  • HODGKIN LYMPHOMA TREATMENT REGIMENS (Part 1 of 2)
    HODGKIN LYMPHOMA TREATMENT REGIMENS (Part 1 of 2) The selection, dosing, and administration of anticancer agents and the management of associated toxicities are complex. Drug dose modifications and schedule and initiation of supportive care interventions are often necessary because of expected toxicities and because of individual patient variability, prior treatment, and comorbidities. Thus, the optimal delivery of anticancer agents requires a healthcare delivery team experienced in the use of such agents and the management of associated toxicities in patients with cancer. The cancer treatment regimens below may include both FDA-approved and unapproved uses/regimens and are provided as references only to the latest treatment strategies. Clinicians must choose and verify treatment options based on the individual patient. NOTE: GREY SHADED BOXES CONTAIN UPDATED REGIMENS.

  • Seattle Genetics and Genmab Enter Into New Antibody-Drug Conjugate Collaboration
    Seattle Genetics and Genmab Enter Into New Antibody-Drug Conjugate Collaboration Company Announcement • Additional collaboration combines Genmab’s proprietary antibodies and Seattle Genetics’ ADC technology • New ADC program will target AXL expressed on multiple tumor types Bothell, WA and Copenhagen, Denmark; September 10, 2014 – Seattle Genetics, Inc. (Nasdaq: SGEN) and Genmab A/S (OMX: GEN) today announced that the companies have entered into an additional antibody-drug conjugate (ADC) collaboration. Under the new agreement, Genmab will pay an upfront fee of $11 million for exclusive rights to utilize Seattle Genetics’ auristatin-based ADC technology with Genmab’s HuMax®-AXL, an antibody targeting AXL which is expressed on multiple types of solid cancers. Seattle Genetics is also entitled to receive more than $200 million in potential milestone payments and mid-to-high single digit royalties on worldwide net sales of any resulting products. In addition, prior to Genmab’s initiation of a Phase III study for any resulting products, Seattle Genetics has the right to exercise an option to increase the royalties to double digits in exchange for a reduction of the milestone payments owed by Genmab. Irrespective of any exercise of option, Genmab remains in full control of development and commercialization. “This collaboration with Genmab further extends the reach of our industry-leading ADC technology for use with novel oncology targets, while providing us with a compelling financial value proposition as the program advances,” said Natasha

  • Homogeneous Antibody-Drug Conjugates Via Site-Selective Disulfide Bridging
    Homogeneous antibody-drug conjugates via site-selective disulfide bridging Nafsika Forte, Vijay Chudasama, and James R. Baker* Department of Chemistry, University College London, London, UK; email: [email protected] Antibody-drug conjugates (ADCs) constructed using site-selective labelling methodologies are likely to dominate the next generation of these targeted therapeutics. To this end, disulfide bridging has emerged as a leading strategy as it allows the production of highly homogeneous ADCs without the need for antibody engineering. It consists of targeting reduced interchain disulfide bonds with reagents which reconnect the resultant pairs of cysteine residues, whilst simultaneously attaching drugs. The 3 main reagent classes which have been exemplified for the construction of ADCs by disulfide bridging will be discussed in this review; bissulfones, next generation maleimides and pyridazinediones, along with others in development. Introduction In the past decades, the potential of monoclonal antibodies (mAbs) in targeted therapy against cancer has been realized, with the market of therapeutic antibodies currently being the fastest growing sector in the pharmaceutical industry. While unmodified antibodies have demonstrated unprecedented activities in the clinic, their action can also be synergistically improved by arming them with cytotoxic drugs to create a new class of targeted therapy, i.e. antibody-drug conjugates (ADCs).1,2 This strategy has great potential to dramatically reduce the side-effects observed with standard chemotherapy,

ADCs have made considerable progress in 10 years. While in 2009 only gemtuzumab ozogamicin (Mylotarg®) was used clinically, in 2020, 9 Food and Drug Administration (FDA)-approved ADCs are available, and more than 80 others are in active clinical studies. This review will focus on FDA-approved and late-stage ADCs, their limitations including their toxicity and associated resistance mechanisms, as well as new emerging strategies to address these issues and attempt to widen their therapeutic window. Finally, we will discuss their combination with conventional chemotherapy or checkpoint inhibitors, and their design for applications beyond oncology, to make ADCs the magic bullet that Paul Ehrlich dreamed of.

Among adults, for patients with advanced HL (stage III/IV disease) there are about 9,060 new cases with a reported death of recommend adriamycin, bleomycin, vinblastine, and 1,190 in 2012 (1). Current standard first-line regimens dacarbazine (ABVD), or escalated bleomycin, etoposide, include adriamycin, bleomycin, vinblastine, dacarbazine adriamycin, cyclophosphamide, vincristine, procarbazine, (ABVD), bleomycin, etoposide, adriamycin, cyclo- and prednisone (BEACOPP) as first-line regimens.

Escalated BEACOPP leads to a Food and Drug Administration (FDA)-approved agent for the greater progression-free survival but no difference in overall treatment of HL in over three decades, has been well-studied survival. Recent advancements in technology have enabled in many trials as a second-line agent after prior failed an exciting shift to molecular-targeted cancer therapy. chemotherapies. However, through our comprehensive Brentuximab vedotin, a CD30-directed antibody conjugate, literature research we did not find any study that reported the specifically targets malignant HL cells.
