Cook pasta as directed on package.
Meanwhile prepare the clam sauce. Mix cornstarch and white wine until blended; set aside. Drain clams, reserving 1 1/4 cups of juice.
Heat oil in large skillet on medium heat. Add garlic; cook and stir 1 minute or until very lightly browned. Add 1 1/4 cups reserved clam juice, parsley and red pepper. Gradually stir in cornstarch mixture. Bring to boil. Boil 1 minute, stirring constantly until sauce is thickened. Add clams; cook until heated through.
Toss sauce with drained pasta. Serve with grated Parmesan cheese, if desired.
