Describe general toxicities for MoABs, and the more unique toxicities related to Blinatumomab and Inotuzumab . Compare and contrast current COG treatment options for patients with B-lineage ALL in 1st and 2nd relapse . Consider important components when developing a nursing care plan for patients receiving Blinatumomab and Inotuzumab 4 C211_A Tale of Two MoABs: Blinatumomab and Inotuzumab in COG Clinical Trials for Relapsed B-ALL 4 Thursday, September 13, 2018 COG Track at APHON 4:45PM-5:45PM Background of the Problem . Despite highly effective front-line therapies for ALL, there continues to be a subset of patients who remain at increased risk of relapse or who have refractory disease . Current standard regimens for relapsed ALL employ intensive cytotoxic therapy with potential for significant short and long-term toxicities ♦ Further dose escalation of therapy is unlikely to improve outcomes and may result in increased toxicities .

Despite early disappointments, monoclonal antibodies targeting CD38 (daratumumab) and signaling lymphocytic activation molecule F7 (SLAMF7) (elotuzumab) have become available for patients with multiple myeloma in the same year. Specifically, phase 3 clinical trials of combination therapies incorporating daratumumab or elotuzumab indicate both efficacy and a very favorable toxicity profile. These therapeutic monoclonal antibodies for multiple myeloma can kill target cells via antibody-dependent cell-mediated cytotoxicity, complement-dependent cytotoxicity, and antibody-dependent phagocytosis, as well as by direct blockade of signaling cascades.

These agents provide numerous benefits compared to traditional small molecule drugs, though their clinical use still requires optimization. The pharmacology of mAbs/ADCs is complex and because ADCs are comprised of multiple components, individual agent characteristics and patient variables can affect their disposition. To further improve the clinical use and rational development of these agents, it is imperative to comprehend the complex mechanisms employed by antibody-based agents in traversing numerous biological barriers and how agent/patient factors affect tumor delivery, toxicities, efficacy, and ultimately, biodistribution.

  • The Potential of Adoptive Transfer of Γ9δ2 T Cells to Enhance
    www.nature.com/scientificreports OPEN The potential of adoptive transfer of γ9δ2 T cells to enhance blinatumomab’s antitumor activity against B‑cell malignancy Yun‑Hsiang Chen1, Yun Wang2, Cheng‑Hao Liao3 & Shu‑Ching Hsu4,5,6,7,8,9* Blinatumomab, a bispecifc T cell engager (BiTE) antibody targeting CD19 and CD3ε, can redirect T cells toward CD19‑positive tumor cells and has been approved to treat relapsed/refractory B‑cell acute lymphoblastic leukemia (R/R B‑ALL). However, chemotherapeutic regimens can severely reduce T cells’ number and cytotoxic function, leading to an inadequate response to blinatumomab treatment in patients. In addition, it was reported that a substantial portion of R/R B‑ALL patients failing blinatumomab treatment had the extramedullary disease, indicating the poor ability of blinatumomab in treating extramedullary disease. In this study, we investigated whether the adoptive transfer of ex vivo expanded γ9δ2 T cells could act as the efector of blinatumomab to enhance blinatumomab’s antitumor activity against B‑cell malignancies in vivo. Repeated infusion of blinatumomab and human γ9δ2 T cells led to more prolonged survival than that of blinatumomab or human γ9δ2 T cells alone in the mice xenografted with Raji cells. Furthermore, adoptive transfer of γ9δ2 T cells reduced tumor mass outside the bone marrow, indicating the potential of γ9δ2 T cells to eradicate the extramedullary disease. Our results suggest that the addition of γ9δ2 T cells to the blinatumomab treatment regimens could be an efective approach to enhancing blinatumomab’s therapeutic efcacy. The concept of this strategy may also be applied to other antigen‑specifc BiTE therapies for other malignancies.

  • Antibody-Drug Conjugates of Calicheamicin Derivative: Gemtuzumab Ozogamicin and Inotuzumab Ozogamicin
    CCR FOCUS Antibody-Drug Conjugates of Calicheamicin Derivative: Gemtuzumab Ozogamicin and Inotuzumab Ozogamicin Alejandro D. Ricart Abstract Antibody-drug conjugates (ADC) are an attractive approach for the treatment of acute myeloid leukemia and non-Hodgkin lymphomas, which in most cases, are inherently sensitive to cytotoxic agents. CD33 and CD22 are specific markers of myeloid leukemias and B-cell malignancies, respectively. These endocytic receptors are ideal for an ADC strategy because they can effectively carry the cytotoxic payload into the cell. Gemtuzumab ozogamicin (GO, Mylotarg) and inotuzumab ozogamicin consist of a derivative of calichea- micin (a potent DNA-binding cytotoxic antibiotic) linked to a humanized monoclonal IgG4 antibody directed against CD33 or CD22, respectively. Both of these ADCs have a target-mediated pharmacokinetic disposition. GO was the first drug to prove the ADC concept in the clinic, specifically in phase II studies that included substantial proportions of older patients with relapsed acute myeloid leukemia. In contrast, in phase III studies, it has thus far failed to show clinical benefit in first-line treatment in combination with standard chemotherapy. Inotuzumab ozogamicin has shown remarkable clinical activity in relapsed/refractory B-cell non-Hodgkin lymphoma, and it has started phase III evaluation. The safety profile of these ADCs includes reversible myelosuppression (especially neutropenia and thrombocyto- penia), elevated hepatic transaminases, and hyperbilirubinemia. There have been postmarketing reports of hepatotoxicity, especially veno-occlusive disease, associated with GO. The incidence is 2%, but patients who undergo hematopoietic stem cell transplantation have an increased risk. As we steadily move toward the goal of personalized medicine, these kinds of agents will provide a unique opportunity to treat selected patient subpopulations based on the expression of their specific tumor targets.

POLICY CRITERIA | CODING | RELATED INFORMATION EVIDENCE REVIEW | REFERENCES | HISTORY ∞ Clicking this icon returns you to the hyperlinks menu above. Introduction An antibody is a blood protein. When the immune system detects an unhealthy cell, antibodies link to a molecule, known as an antigen, on the unhealthy cell. Monoclonal antibodies are produced in a laboratory. They are made to link to antigens usually found in high numbers on cancer cells. Antibody-drug conjugates combine monoclonal antibodies with certain chemotherapy drugs. The monoclonal antibodies find the cancer cells and the chemotherapy drug is released directly into those cells. The goal with this treatment is to target only cancer cells and spare nearby healthy cells. This policy describes when specific antibody-drug conjugates may be considered medically necessary. Note: The Introduction section is for your general knowledge and is not to be taken as policy coverage criteria. The rest of the policy uses specific words and concepts familiar to medical professionals. It is intended for providers. A provider can be a person, such as a doctor, nurse, psychologist, or dentist.

  • Antibody-Drug Conjugate Resurgence Continues with Lumoxiti
    September 14, 2018 Antibody-drug conjugate resurgence continues with Lumoxiti Jacob Plieth With today’s approval of Astrazeneca’s Lumoxiti the US market has two antibody-drug conjugates against the CD22 antigen. While the first, Pfizer’s Besponsa, was approved a year ago for treating relapsed adult acute lymphoblastic leukaemia (ALL), Astra has positioned Lumoxiti against hairy cell leukaemia, a relatively rare malignancy. Both these haematological cancers affect B cells, hence the relevance of hitting CD22, an antigen present on this cell lineage. An important difference between Besponsa and Lumoxiti is the cytotoxic payload each carries – respectively calicheamicin, the same as that used in Pfizer’s Mylotarg, and Pseudomonas exotoxin A. And both drugs’ labels carry boxed warnings, respectively for liver damage and capillary leak syndrome, the toxicity that briefly derailed Stemline’s anti-CD123 conjugate SL-401. The next anti-CD22 asset to test the regulators could be Immunomedics’ epratuzumab, though as this is a standard “naked” antibody it is unlikely to match the efficacy of more advanced constructs like conjugates and bispecifics. The big competitor could emerge in the form of CD22-directed CAR-T therapy, though this is still some way off being commercialised.
