Have you read The Body and Society by Peter Brown? It's a thorough and well-written look at the development of early Christian monasticism.

Might also look into: Samuel Rubenson, The Letters of St. Antony: Monasticism and the Making of a Saint. I believe he specifically mentions Therapeutae at some point.

Hopefully someone else can come along with something specific and maybe even more recent, but i know both of those treat the Jewish influence.

Edit:

Might also consider Jewish Women Philosophers of First-Century Alexandria: Philo's 'Therapeutae' Reconsidered by Joan Taylor. I have not read that book, but it seems to be the most comperhensive study of Philo and Therapeutae.
