Sed regex problem on Mac, works fine on Linux

This works fine on Linux (Debian):

sed -e 's,^[ \t]*psd\(.*\)\;,,' 

On mac, I believe I have to use the -E flag, instead of -e:

sed -E 's,^[ \t]*psd\(.*\)\;,,'

but the regexp does not match, and hence does not remove the lines I want.

Any tips on how to solve this?

Sample input:

apa
bepa
    psd(cepa);
depa psd(epa);
  psd(fepa gepa hepa);

For that input, the expected output is:

apa
bepa
depa psd(epa);
