   OPINION

PER CURIAM.

Maurice Thomas seeks a writ of mandamus to address alleged delays in the adjudication of his criminal proceedings in the United States District Court for the Eastern District of Pennsylvania. A writ of mandamus is a drastic remedy available only in extraordinary cases. See In re Diet Drugs Prods. Liab. Litig., 418 F.3d 372, 378 (3d Cir.2005). A party seeking mandamus must show that he has “no other adequate means to attain the relief he desires” and that his right to the writ is “clear and indisputable.” Hollingsworth v. Perry, 558 U.S. 183, 190, 130 S.Ct. 705, 175 L.Ed.2d 657 (2010) (per curiam) (quotation marks omitted).

In October 2012, the District Court denied Thomas’ counseled motion to dismiss the charges against him based in part on his right to a speedy trial. To the extent Thomas intends to challenge that ruling he may not do so via a petition for a writ of mandamus. A mandamus petition is not a substitute for an appeal and may not be used to circumvent the final judgment rule. In re Baldwin, 700 F.3d 122, 127 (3d Cir.2012); In re Kensington Int’l Ltd., 353 F.3d 211, 219 (3d Cir.2003). If he is convicted, Thomas may challenge the District Court’s interlocutory rulings by taking an appeal after entry of a final judgment. See, e.g., United States v. Graves, 722 F.3d 544, 545-49 (3d Cir.2013) (reviewing Speedy Trial Act claim on direct appeal); United States v. Willaman, 437 F.3d 354, 357-59 (3d Cir.2006) (same). Accordingly, we will deny the petition for a writ of mandamus. 
      
      . Although he is represented by counsel in the District Court, he has filed his mandamus petition pro se.
     
      
      . A District Court’s denial of a speedy trial motion is not immediately appealable. United States v. Culbertson, 598 F.3d 40, 48 (2d Cir.2010) ("a district court’s order denying dismissal for an alleged violation of a defendant’s right to a speedy trial is not reviewable on interlocutory appeal”) (citing United States v. MacDonald, 435 U.S. 850, 857, 98 S.Ct. 1547, 56 L.Ed.2d 18 (1978)); cf. United States v. Kuper, 522 F.3d 302, 303-305 (3d Cir.2008) (holding that an order dismissing an indictment without prejudice pursuant to the Speedy Trial Act is not immediately appeal-able and may be appealed if defendant is re-indicted and convicted).
