MEMORANDUM **
California state prisoner Anthony Huckabee appeals pro se from the district courts summary judgment in his 42 U.S.C. § 1983 action alleging deliberate indifference to his serious medical needs. We have jurisdiction under 28 U.S.C. § 1291. We review de novo. Toguchi v. Chung, 391 F.3d 1051, 1056 (9th Cir. 2004). We affirm.
The district court properly granted summary judgment for defendant Wu regarding the change in Huckabees Timolol prescription, and defendants Jimenez and McGuiness regarding the renewal of Huckabees Timolol prescription, because Huckabee failed to raise a genuine dispute of material fact as to whether defendants were deliberately indifferent to his serious medical needs. See id. at 1057-60 (deliberate indifference is a high legal standard, and a prison official is deliberately indifferent only if he or she knows of and disregards an excessive risk to the prisoners health; medical malpractice or negligence concerning the course of treatment does not amount to deliberate indifference).
The district court did not abuse its discretion by denying Huckabee leave to file a sixth amended complaint because amendment would have been futile. See Serra v. Lappin, 600 F.3d 1191, 1200 (9th Cir. 2010) (setting forth standard of review and factors for determining whether to grant leave to amend); Metzler Inv. GMBH v. Corinthian Colls., Inc., 540 F.3d 1049, 1072 (9th Cir. 2008) (“[T]he district courts discretion to deny leave to amend is particularly broad where plaintiff has previously amended the complaint.” (citation and internal quotation marks omitted)).
The district court did not abuse its discretion by permitting McGuiness to file a joinder in a motion for summary judgment filed by defendants Enenmoh, Jimenez, and Wu. See Christian v. Mattel, Inc., 286 F.3d 1118, 1129 (9th Cir. 2002) (setting forth standard of review and noting a district courts “considerable latitude in managing the parties’ motion practice”).
We do not consider matters not specifically and distinctly raised and argued in the opening brief. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).
AFFIRMED.
