Purpose: To report a case of bilateral Vogt-Koyanagi-Harada (VKH)-like granulomatous pan uveitis secondary to brentuximab vedotin (BV) administration to treat for classical Hodgkin lymphoma (CHL).
Observations: A case of bilateral pan uveitis is described, following administration of BV, with features of VKH-like uveitis: presence of inflammatory cells in the anterior and posterior segment, multiple small serous detachments around the optic disc and retinal pigment epithelium (RPE) folds confirmed by optical coherence tomography (OCT) as well as hypocyanesent dark dots, disc hyperfluorescence and fuzzy vascular patterns seen on indocyanine green and fluorescein angiography. There were no systemic features of VKH disease. Further etiological investigation showed no clear infectious or inflammatory cause. The uveitis responded well to treatment with corticosteroids and cessation of BV. A relapse occurred a few months later when BV treatment was reinitiated, suggesting a probable adverse event to this drug, according to the Naranjo algorithm.
Conclusions: We hypothesize that administration of BV can induce a VKH-like uveitis, caused by loss of function of protective CD30 cells present in the uveal tract, possibly aggravated by collateral damage to surrounding CD30cells and melanocytes, leading to a uveal immune reaction. It is therefore important for the clinicians using BV to be aware of this adverse event. Growing experience with immunotherapy will provide more clinical insights in these complex immune mechanisms in the future.

Background: Synchronous malignant histiocytoses are rare conditions that occur concurrently with another hematologic neoplasm. Most reported cases are associated with B-cell lymphoproliferative disorders, while associations with T-cell hemopathies are less common. These two diseases may share mutations and/or cytogenetic anomalies, which can lead to malignant proliferations.

This study was designed to assess the effect of brentuximab vedotin on several breast cancer cell lines in terms of promoting apoptosis and managing cancer progression. Additionally, the study investigated the potential of repurposing this drug for new therapeutic reasons, beyond its original indications. The study evaluates the cytotoxic effects of Brentuximab vedotin across five cell lines: normal human skin fibroblasts (HSF), three breast cancer cell lines (MCF-7, MDA-MB-231, and T-47D), and histiocytic lymphoma (U-937).

Brentuximab vedotin (BV) is an antibody-drug conjugate that combines the CD30 monoclonal antibody with the microtubule-disrupting agent, monomethyl auristatin E, which induces apoptosis in the tumor cell upon its release from the conjugate. The safety and efficacy of BV have been assessed in several studies in patients with T- and B-cell lymphomas. This article reviews the currently available data on the distribution of CD30 expression in T- and B-cell lymphomas, as well as the various levels of CD30 positivity cutoff used in the literature.

Antibody-drug conjugates (ADCs) have advanced as a mainstay among the most promising cancer therapeutics, offering enhanced antigen targeting and encompassing wide diversity in their linker and payload components. Small-molecule inhibitors of tubulin polymerization have found success as payloads in FDA approved ADCs and represent further promise in next-generation, pre-clinical and developmental ADCs. Unique dual-mechanism payloads (previously designed and synthesized in our laboratories) function as both potent antiproliferative agents and promising vascular disrupting agents capable of imparting selective and effective damage to tumor-associated microvessels.

Brentuximab vedotin (BV) plus doxorubicin, vinblastine and dacarbazine (AVD) demonstrated to improve survival compared to ABVD as frontline treatment of advanced stage Hodgkin Lymphoma (HL). We retrospectively collected data of 99 stage IV HL patients treated off-protocol with BV-AVD to evaluate the predictive role of interim-PET. Median age was 36 years (range: 18-82); 83.
