Pegcetacoplan is a subcutaneously administered C3-targeted therapy, which may be suitable for treating CAD and wAIHA. In this open-label phase 2 study, analyses were conducted in 2 cohorts, 1 for patients with CAD and the other for those with wAIHA. In each cohort, patients were randomly assigned to receive pegcetacoplan 270 mg/d or 360 mg/d for up to 48 weeks. Safety end points included the incidence and severity of treatment-emergent adverse events (TEAEs) and adverse events of special interest (AESI). Efficacy end points included change from baseline in hemoglobin (Hb), lactate dehydrogenase, absolute reticulocyte count, haptoglobin, indirect bilirubin, and functional assessment of chronic illness therapy (FACIT)-fatigue scale. Thirteen of 13 (100%) and 10 of 11 (91%) patients with CAD and wAIHA, respectively, experienced at least 1 TEAE. Ten patients had at least 1 serious AE; none were considered related to pegcetacoplan. The only treatment-related AESIs were injection site reactions. Pegcetacoplan increased Hb levels, reduced hemolysis, and increased FACIT-fatigue scale scores in the first weeks; at week 48 the median (interquartile range) change from baseline Hb for the CAD and wAIHA total groups was 2.4 (0.90-3.00) and 1.7 g/dL (-1.40 to 2.90), respectively, and improvements in hemolysis and FACIT-fatigue scale scores were maintained. This study demonstrated that pegcetacoplan is generally well tolerated and suggests it can be effective for patients with CAD and wAIHA.

MDS presents later in life, has a limited repertoire of life-extending therapies, and patients may have comorbidities acting as competing causes of death. However, refined prognostication identifies patients with MDS with a reasonable life expectancy, and because 50% of patients will ultimately become RBC TD and develop transfusional IOL, ICT should be considered in some. Using illustrative cases, we summarize mechanisms of iron toxicity, strategies for the identification of IOL, and propose definitions of IOL severity. We provide rationale for, and recommend which patients may benefit from, ICT. We discuss currently available chelators, their administration, monitoring, side effects, and their management. Given challenges with the use of iron chelators, we suggest the nuances to be considered when planning chelation initiation to include the rate of iron accumulation, the presence of organ iron and/or dysfunction, and detectable indicators of oxidative stress.

However, identifying patients likely to respond remains a challenge, especially for those with relapsed/refractory (R/R) disease. We evaluated the utility of ex vivo venetoclax sensitivity testing to predict treatment responses to venetoclax-azacitidine in a prospective, multicenter, phase 2 trial. The trial recruited 104 participants with previously untreated (n = 48), R/R (n = 39), or previously treated secondary AML (sAML) (n = 17). The primary end point was complete remission or complete remission with incomplete hematologic recovery (CR/CRi) rate in ex vivo sensitive trial participants during the first 3 therapy cycles. The key secondary end points included the correlations between ex vivo drug sensitivity, responses, and survival. Venetoclax sensitivity was successfully assessed in 102 of 104 participants, with results available within a median of 3 days from sampling. In previously untreated AML, ex vivo sensitivity corresponded to an 85% (34/40) CR/CRi rate, with a median overall survival (OS) of 28.7 months, compared with 5.5 months for ex vivo resistant patients (P = .002). For R/R/sAML, ex vivo sensitivity resulted in a 62% CR/CRi rate (21/34) and median OS of 9.7 vs 3.3 months for ex vivo resistant patients (P < .001). In univariate and multivariate analysis, ex vivo venetoclax sensitivity was the strongest predictor for a favorable treatment response and survival. This trial demonstrates the feasibility of integrating ex vivo drug testing into clinical practice to identify patients with AML, particularly in the R/R setting, who benefit from venetoclax.
