The present disclosure provides methods for genetically engineering T cells, such as CD4+ T cells, for use in cell therapy. In some aspects, the provided methods include one or more steps for incubating the cells under stimulating conditions, introducing a recombinant polypeptide to the cells through transduction or transfection, and cultivating the cells under conditions that promote proliferation and/or expansion. In some aspects, the incubation and/or the cultivation is performed in the presence of recombinant IL-2. In some aspects, the provided methods are an efficient, reliable means to produce genetically engineered T cells with a high degree of success.

Process for generating therapeutic compositions of engineered cells

Provided are methods, systems, and kits for cell processing, e.g., for therapeutic use, such as for adoptive cell therapy. The provided methods include transduction methods, in which cells and virus are incubated under conditions that result in transduction of the cells with a viral vector. The incubation in some embodiments is carried out in an internal cavity of a generally rigid centrifugal chamber, such as a cylindrical chamber made of hard plastic, the cavity of which may have a variable volume. The methods include other processing steps, including those carried out in such a chamber, including washing, selection, isolation, culture, and formulation. In particular, the disclosure relates to method providing advantages over available processing methods, such as available methods for large-scale processing. Such advantages include, for example, reduced cost, streamlining, increased efficacy, increased safety, and increased reproducibility among different subjects and conditions.
