Safety
6-YEAR MEDIAN FOLLOW-UP
Safety and tolerability at 74.5-month median follow-up were consistent with the established profile of CALQUENCE*1
At 28.3-month median follow-up4:
- Select non-hematologic laboratory abnormalities (≥15%, any grade) that were new or worsening from baseline in patients receiving CALQUENCE included increases in uric acid, alanine aminotransferase, aspartate aminotransferase, and bilirubin. Electrolytes were excluded4
- Increases in creatinine to 1.5 to 3 times the upper limit of normal occurred in 3.9% and 2.8% of patients in the CALQUENCE + obinutuzumab and CALQUENCE monotherapy arms, respectively4
Events of clinical interest at 74.5-month median follow-up were consistent with the established profile of CALQUENCE1
Low rates of atrial fibrillation, hypertension, and major
bleeding at 74.5-month median follow-up1
At 74.5-month median follow-up:
- The most common AEs (≥30%) of any grade in the CALQUENCE + obinutuzumab arm (n=178) were infection (83%), bleeding (53%), diarrhea (44%), headache (40%), arthralgia (36%), neutropenia (34%), and fatigue (31%). In the CALQUENCE monotherapy arm (n=179), the most common AEs (≥30%) of any grade were infection (80%), bleeding (45%), diarrhea (43%), and headache (39%)1
- Median duration of CALQUENCE exposure was 74.4 months with CALQUENCE + obinutuzumab and 72.0 months with CALQUENCE monotherapy1
At 28.3-month median follow-up:
- The most common ARs (≥30%) of any grade in patients treated with CALQUENCE + obinutuzumab (n=178) were infection (69%), neutropenia (53%), anemia (52%), thrombocytopenia (51%), headache (40%), diarrhea (39%), musculoskeletal pain (37%), fatigue (34%), and bruising (31%). In the CALQUENCE monotherapy arm (n=179), the most common ARs (≥30%) of any grade were infection (65%), anemia (53%), headache (39%), diarrhea (35%), musculoskeletal pain (32%), and thrombocytopenia (32%)4
- Other clinically relevant adverse reactions (<15%, any grade) in recipients of CALQUENCE included neoplasms (second primary malignancy [10%], including non-melanoma skin cancer [5%]); infection (herpes virus infection [6%]); and cardiac disorders (atrial fibrillation or flutter [3.6%] and hypertension [5%])4
- In the CALQUENCE + obinutuzumab and CALQUENCE monotherapy arms, fatal ARs that occurred in the absence of disease progression and with onset within 30 days of the last study treatment were reported in 2% for each treatment arm, most often from infection. Serious ARs were reported in 39% of patients in the CALQUENCE + obinutuzumab arm and 32% in the CALQUENCE monotherapy arm, most often due to events of pneumonia (7% and 2.8%, respectively)4
- Median duration of CALQUENCE exposure was 27.7 months with CALQUENCE + obinutuzumab and CALQUENCE monotherapy4
In a pooled analysis of 1029 patients with CALQUENCE, Grade 3 or higher ventricular arrhythmia events were reported in 0.9% of patients.
