P1, N=7, Terminated, Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins | N=36 --> 7 | Trial completion date: Dec 2028 --> Jul 2025 | Active, not recruiting --> Terminated; Upon analysis of the first 7 participants accrued, it was determined that this combination treatment is not efficacious as treatment for patients with relapsed or refractory AML

The risk-based approach and use of targeted therapies in CHIP-AML22 illustrate a shift toward more personalized treatment. Besides improving event-free survival, this study aims to contribute to the international consensus on strategies to reduce toxicity for all patients. The design of this study provides a dynamic framework, allowing for the potential introduction of emerging therapeutic options in the future.

The anti-CCRL2 ADC demonstrated strong CCRL2-selective cytotoxicity against cell lines derived from MDS/AML patients with TP53 mutations and erythroid features, surpassing the cytotoxic effects observed with gemtuzumab and PBD-conjugated anti-CD33 and anti-CD123 ADCs...This agent also suppressed the leukemic growth of TP53-mutated MDS/AML cell line xenografts, improving mice survival and decreasing the leukemic burden in patient-derived TP53-mutated MDS/AML xenografts. In conclusion, our study introduces CCRL2 as a potential new therapeutic target in high-risk MDS/AML including TP53-mutated subsets.

To our knowledge, this is the first study to investigate the prognostic impact of the CD33 rs12459419 SNP per se on outcome and survival in adult AML patients treated with chemotherapy without GO. Validation in larger patient cohorts is required to conclusively rule out a prognostic role of the CD33 rs12459419 SNP in AML.

In summary, trem-cel demonstrated safe, rapid, robust engraftment, and GO maintenance was administered without prolonged hematologic toxicity. ClinicalTrials.gov identifier: NCT04849910 .

The patient achieved complete remission following the standard 7 + 3 induction chemotherapy regimen for AML with gemtuzumab ozogamicin. This case illustrates the diagnostic challenges posed by concomitant class-defining alterations in hematologic neoplasms and underscores the importance of integrated genomic assessment.
