Practical Guidance on Clinical Management of Belantamab Mafodotin‐Associated Ocular Events
Bibliographic record
Abstract
IMPORTANCE: Belantamab mafodotin (belamaf)-containing regimens are effective treatment options for patients with relapsed and/or refractory multiple myeloma. Ocular events are a common adverse effect of belamaf treatment, which can be managed by physicians, following appropriate training, to minimize their impact on the patient. OBJECTIVE: To develop clinical recommendations for the identification, monitoring, and management of ocular events associated with belamaf therapy, and guidance for any required dose modification. EVIDENCE REVIEW: A systematic literature review was conducted and an international group of hematologists and ophthalmologists reviewed clinical trial data, real-world evidence, and published literature on belamaf-associated ocular events. This literature review and the collective experience and expertise of the panel of experts informed the recommendations. FINDINGS: Belamaf-associated ocular events are common side effects of treatment, which are managed primarily with appropriate dose modification and decreased frequency of dosing, as well as the use of artificial tears. These events affect the corneal epithelium, are mainly Grade 1 and 2 per the Keratopathy and Visual Acuity scale and are reversible in almost all patients. In general, before initiating belamaf therapy, all patients should undergo a baseline ophthalmic evaluation with an eye specialist. However, if there are delays in obtaining ophthalmic evaluation, or if a patient is rapidly progressing, treatment should be initiated, and ophthalmic evaluation should be undertaken as soon as possible. Patients should be also evaluated by an eye specialist before administering the next three belamaf doses (i.e., before Cycles 2, 3, and 4); dose modifications, as described in this paper, may apply if required. Importantly, modifying the belamaf dose in response to an ocular event is not associated with any reductions in treatment efficacy. After Cycle 4, the treating physician may use the Vision-Related Anamnestic tool, alongside clinical judgment, to decide whether to administer the next dose of belamaf or to refer the patient to an eye specialist (i.e., if the patient experiences new worsening of vision or if the ocular events have neither improved after 8 weeks nor resolved after 12 weeks). CONCLUSIONS AND RELEVANCE: The expert panel developed recommendations for managing belamaf-associated ocular events, with the aim of contributing to the ease of clinical use of belamaf and improving patient outcomes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
