Philadelphia (Ph)-like acute lymphoblastic leukemia (ALL) Desktop Vaporizers constitutes a heterogeneous subset of ALL with a uniformly unfavorable prognosis.The identification of mutations amenable to treatment with tyrosine kinase-inhibitors (TKIs) represents a promising field of investigation.We report the case of a young patient affected by relapsed/refractory Ph-like ALL treated with chimeric antigen receptor T (CAR-T) cells after trikes successful bridging with compassionate-use ponatinib and low-dose prednisone.

We restarted low-dose ponatinib maintenance three months later.Twenty months later, measurable residual disease negativity and B-cell aplasia persist.To the best of our knowledge, this is the first case reporting the use of ponatinib in Ph-like ALL as a bridge to and maintenance after CAR-T cell therapy.
