Nevertheless, Vectibix remains an important monotherapy treatment choice for patients with metastatic colorectal tumor whose disease provides progressed on various other therapies, stated Roger M. Perlmutter, M.D., Ph.D., executive vice president of Development and Research at Amgen. The SPECTRUM study enrolled 658 patients who were randomized to receive a standard platinum-structured chemotherapy , with or without Vectibix every three weeks.Data were gathered on measures including heart rate at rest, by the end of the treadmill test and during recovery, heart rate reserve , exercise duration, diastolic and systolic blood pressure, and the presence of any ventricular or atrial arrhythmias during exercise. The average age at first assessment of the patients who went on to be diagnosed with PD was 64.8 years, compared with 48.9 years in the control group. Typically, PD manifested 4.6 years following the first assessment. When the researchers primarily analyzed the results, they discovered that people in the PD group had a considerably lower heart rate at maximal effort, a lower heartrate reserve, and a higher systolic blood circulation pressure at rest and during recovery weighed against controls.
