RESUMEN
As the world of cellular therapy expands to include immune effector cell (IEC) products such as commercial chimeric antigen receptor (CAR) T cells, quality management (QM) professionals are faced with creating either new IEC stand-alone programs or expand existing hematopoietic cell transplantation (HCT) programs to promote patient safety and be aligned with quality, regulatory, and accreditation requirements. The team professionals at City of Hope (COH) recently expanded the quality HCT program to include IEC products and, in doing so, implemented new regulatory infrastructure while maintaining high quality patient care. At COH, we developed the quality structure of our cellular therapy program through collaborations between quality, regulatory, and CAR T patient care committees, which included physicians and nurse coordinators. To ensure the quality of our program, we monitor data collection and reporting, perform quarterly proactive audits of, for example, outcome analysis, and measure selected end-points for benchmarking purposes. QM professionals play a critical role in the monitoring and evaluation processes and provide guidance on how to implement accreditation requirements and what impact the requirements may have on care management. Here we describe the process by which COH expanded our HCT QM program to include IEC therapy. We share examples of how we developed our overall program structure and other key items such as how we addressed patient care management and accreditation to apprise other programs that wish to create and/or expand existing programs.

PURPOSE: Vascular endothelial growth factor antisense (VEGF-AS) is an antisense oligonucleotide that targets VEGF, inhibiting angiogenesis and tumor cell proliferation. This study established the safety, biologic effects, and pharmacokinetics of VEGF-AS in 51 patients with advanced malignancies. METHODS: VEGF-AS was administered as a 2-hour infusion daily for 5 consecutive days for only one cycle on the first four dose levels, and then administered daily for 5 days every other week for up to 4 months on subsequent levels. Pharmacokinetics, tumor response, and the effect on plasma VEGF levels were determined. RESULTS: The maximum-tolerated dose was 200 mg/m2. Dose-limiting toxicities included grade 4 fever, and pulmonary embolism in one patient each at 250 mg/m2. Mild anemia, fever, fatigue, and gastrointestinal complaints were the most common adverse events. VEGF-AS t(1/2beta) (beta-phase terminal half-life of drug concentration) was 2.25 hours (range, 1.97 to 2.95 hours). Mean plasma VEGF-A (P = .002) and VEGF-C (P = .01) levels decreased 24 hours postinfusion, with a trend towards greater decreases at higher dose levels. At the maximum-tolerated dose, five of six patients demonstrated reductions in plasma VEGF. Clinical responses included complete remission in one patient with AIDS-Kaposi's sarcoma, a mixed but dramatic response in one patient with cutaneous T-cell lymphoma, and prolongation of progression-free survival compared with that obtained on the immediate prior regimen in six patients (12%) with renal cell, bronchoalveolar, small cell lung, thyroid, and ovarian carcinomas, and chondrosarcoma, respectively. CONCLUSION: VEGF-AS was well tolerated, with biologic effects and preliminary evidence of clinical efficacy.
