Calquence and depression

I have CLL and have been on Calquence for about 14 months. 8 months ago out of the blue I started getting severely depressed. I am a 67 year old
male and I live a happy life. I have never been depressed. This was and is purely biological. I am currently still fighting it and am on a couple of anti-depressants which is also a first for me. I asked my oncologist if there was anyway that the Calquence could have triggered the depression and he was adamant about the fact that there was no research that indicated that it’s possible side effect. I have seen some people reference it on line but am curious if anyone in this group has thoughts about this or has experienced it. Thank you .
