6 ADVERSE REACTIONS The most common (incidence of greater than or equal to 20%) non-laboratory adverse reactions in order of decreasing frequency were chills, pyrexia, fatigue, tachycardia, diarrhea, febrile neutropenia, edema, rash, hypotension, alopecia, infection, hypoxia, and dyspnea.

The serious adverse reactions included: Treatment-Related Mortality [see Warnings and Precautions (5.1) ] Prolonged Severe Cytopenia [see Warnings and Precautions (5.2) ] Internal Organ Hemorrhage [see Warnings and Precautions (5.3) ] Severe Infection [see Warnings and Precautions (5.4) ] Cardiac Disorder [see Warnings and Precautions (5.5) ] Respiratory Failure [see Warnings and Precautions (5.6) ] Acute Renal Failure [see Warnings and Precautions (5.7) ] Hypersensitivity Reactions [see Warnings and Precautions (5.8) ] The most common (incidence of greater than or equal to 20%) non-laboratory adverse reactions in order of decreasing frequency were chills, pyrexia, fatigue, tachycardia, diarrhea, febrile neutropenia, edema, rash, hypotension, alopecia, infection, hypoxia, and dyspnea ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Iovance Biotherapeutics, Inc.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The pooled safety data described in this section reflect exposure to AMTAGVI within a regimen that included cyclophosphamide, fludarabine, and IL-2 (aldesleukin) in the global, multicenter, multicohort, open-label, single-arm clinical study in which 156 adult patients with unresectable or metastatic melanoma received a single infusion of AMTAGVI [see Clinical Studies (14) ] .

The median age of the study population was 56 years (range: 20 to 79 years);

53.8% were men.

The performance status prior to tumor procurement was 68.6% with ECOG 0 and 31.4% with ECOG

Table 1 summarizes the adverse reactions that occurred in at least 10% of patients treated with AMTAGVI and Table 2 describes the laboratory abnormalities of Grade 3 or 4 that occurred in at least 10% of patients.
