I'm interested in Pfizer's clinical trials for oncology. Find out if Pfizer currently has any active clinical trials for 'Breast Cancer' and, if so, identify the number of active trials and the earliest start date among them. If no specific start date is available, state that.
Navigate to pfizer.com. Click on the 'Science' dropdown menu. Click on the 'Clinical Trials' dropdown or 'Find a Trial' link within the 'Science' section. On the clinical trials search page, enter 'Breast Cancer' into the search bar or filter by 'Oncology' and then 'Breast Cancer'. Locate and count the number of active clinical trials for 'Breast Cancer'. For each active trial, attempt to identify the earliest start date. If no specific start date is listed, note that. State the total number of active trials and the earliest start date found, or state if no trials are found.
Successfully navigate to the clinical trials search functionality. Successfully search or filter for 'Breast Cancer' trials within the 'Oncology' area. Identify the number of active clinical trials for 'Breast Cancer'. State the earliest start date found among the active trials, or confirm if no specific start date is provided for any listed trial.
