You can calculate an AP ratio for it because of the direct link from AP->HP from his passive. The ratio is +0.21 AP for the entire duration. Of course this is for the HP that comes solely from his passive, you would have to neglect this HP when calculating total added damage.

In other words you can translate his damages to something similar to:

Maximum Magic Damage: 80 / 135 / 190 / 245 / 300 (+15% of (total bonus health - 1.4 per ability power)) (+0.21 per ability power)

What this does it it calculates the bonus damage from 15% of his bonus health that is not from his AP->HP passive and then calculates the bonus damage from his ability power.
