galiximab (IDEC 114) / Biogen - LARVOL DELTA

Immunotherapy in indolent Non-Hodgkin's Lymphoma. (PubMed, Leuk Res Rep) - "Other than that, a resistance mechanism to rituximab emerged by inducing a failure in the apoptosis mechanism...Here came the development of 90Y-ibritumomab tiuxetan and 131I-tositumomab. After it, humanized anti-CD20 emerged ofatumumab, IMMU106 (veltuzumab) in 2005, and ocrelizumab which are considered as second generation anti-CD20 and 3 generation anti-CD20 include AME-133v (ocaratuzumab), PRO131921 and GA101 (obinutuzumab). Also multiple other agents emerged targeting different surface cell antigens like CD52 (alemtuzumab), CD22 (unconjugated epratuzumab and calicheamicin conjugated CMC-544 [inotuzumab ozogamicin]), CD80 (galiximab), CD2 (MEDI-507 [siplizumab]), CD30 (SGN-30 and MDX-060 [iratumumab], Brentuximab vedotin), CD40 (SGN-40), and CD79b (Polatuzumab). Other agents include MAB targeting T-Cells like mogamulizumab, Denileukin Diftitox and BiTEs or bispecific T cell engagers like Mosunetuzumab, Glofitamab, and Epcoritamab...Another important aspect in..."

CD80 Insights as Therapeutic Target in the Current and Future Treatment Options of Frequent-Relapse Minimal Change Disease. (PubMed, Biomed Res Int) - "The promising effectiveness of CD20 (rituximab) antibody and CD80 inhibitor (abatacept) encourages further investigation of CD80 as a therapeutic target in frequent-relapse MCD patients. Therapeutic-based antibody towards CD80 (galiximab) had never been investigated in MCD or any kidney-related disease; hence, the role of CD80 is still undetermined. A new therapeutic approach towards MCD is essential to provide broader effective treatment options besides the general immunosuppressive agents with gruesome adverse effects."

Galiximab in treating patients with relapsed or refractory Hodgkin's lymphoma (clinicaltrials.gov) - P2, N=30; Active, not recruiting

Hematological Malignancies

Phase II trial of galiximab (anti-CD80 monoclonal antibody) plus rituximab (CALGB 50402): Follicular Lymphoma International Prognostic Index (FLIPI) score is predictive of upfront immunotherapy (Ann Oncol) - P2, N=61; CALGB-50402; ORR is 72.1%; 47.6% CR/ CRu & 24.6% PR; At a median follow-up time of 4.3 years, mPFS=2.9 yrs; The low-risk FLIPI grp (N=12) achieved ORR=92%, CR/CRu rate=75%, & 3-yr PFS=75%; An extended induction schedule of G + R in previously untreated FL is well tolerated & appears particularly efficacious in those pts with low-risk FLIPI scores

The prognostic significance of PFS24 in follicular lymphoma following firstline immunotherapy: A combined analysis of 3 CALGB trials. (PubMed, Cancer Med) - "We performed a retrospective analysis of 174 patients pooled from three frontline rituximab (R)-based nonchemotherapy doublet trials: R-galiximab (Anti-CD80, CALGB 50402), R-epratuzumab (Anti-CD22, CALGB 50701), and R-lenalidomide (CALGB 50803) to determine outcomes of early progressors and risk factors for early POD, defined as progression within 24 months from study entry. For early POD, the 2-year survival was 80% vs 99% for nonearly POD, and the 5-year survival was 74% vs 90%, respectively. These findings suggest that the adverse survival of patients with early POD may be independent of initial treatment modality."

Long-Term Follow-up of Follicular Lymphoma (FL) Patients (pts) Demonstrating Undetectable Minimal Residual Disease (MRD) Using a Next-Generation Based DNA Assay: Support for FL As a Curable Disease (ASH 2019) - "The most common immediately prior line of therapy included bendamustine and rituximab (BR, n=16); rituximab, cyclophosphamide, adriamycin, vincristine, prednisone (RCHOP, n=6); double-monoclonal antibody containing regimens(rituximab-galiximab; rituximab-epratuzumab (n=3)), radioimmunotherapy (n=3), and allogeneic bone marrow transplant (n=2). Additional follow-up is underway to determine if positive pts will eventually relapse. CONCLUSIONS These data are the first to demonstrate that a high proportion of FL pts in a prolonged clinical remission have undetectable DNA by sensitive next generation sequencing, without evidence of clinical progression, and are potentially cured of their disease."
