MEMORANDUM ORDER

DONETTA W. AMBROSE, Senior District Judge.

Plaintiff filed a Motion for Leave to Supplement and Add Defendants at ECF No. 352. Defendant Folino filed a Response at ECF No. 356 and the Medical Defendants filed a Response at ECF No. 357. The issues are now ripe for my review.

In his Motion, filed less than two weeks prior to the start of trial in this case, Plaintiff seeks permission to "add Wexford Medical, Corizon, Prison Health Services (PHS), and America Service Group to this civil action as pertain to supervisor liability under respondeat superior and vicarious liability." [ECF No. 352, at 2]. This request is both untimely and without merit.

As an initial matter, to allow Plaintiff to supplement his causes of action and add new parties at this late stage of the litigation would be highly prejudicial to both Defendants and the parties sought to be added.1 It also would cause unnecessary delay in an action that already has been pending for over five years. Moreover, and in any event, the only claim remaining in this case is a deliberate indifference claim under Section 1983. It is well-established that individual liability under Section 1983 cannot be based upon respondeat superior or vicarious liability theories. See Chavarriaga v. NJ Dep't of Corrections, ___ F.3d ___, 2015 WL 7171306, at *5 (3d Cir. Nov. 16, 2015); Evancho v. Fisher, 423 F.3d 347, 353 (3d Cir. 2005) (citing Rode v. Dellarciprete, 845 F.2d 1195, 1207 (3d Cir. 1988)). For this reason as well, adding the proposed Defendants and claims would be futile and must be denied.

Accordingly, Plaintiff's Motion for Leave to Supplement and Add Defendants at ECF No. 352 is DENIED.

AND NOW, IT IS SO ORDERED.
