A Study to Evaluate the Tolerance and Pharmacokinetics of TQB3602 Capsule

Study Overview
=================
Brief Summary
-----------------
This is a study to evaluate the tolerance, dose-limiting toxicity (DLT), phase II recommended dose (RP2D), and maximum tolerated dose (MTD) of single and multiple oral doses of TQB3474 in patients with advanced malignant tumors.

Life expectancy ≥12 weeks. 5. Relapsed/refractory multiple myeloma had received at least two treatment methods. 6. Male or female subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 6 months after the last dose of study (such as intrauterine devices , contraceptives or condoms) ；No pregnant or breastfeeding women, and a negative pregnancy test are received within 7 days before the randomization. Exclusion Criteria: 1. Hypersensitivity to TQB3602 or its excipient. 2. Has peripheral nerve diseases ≥ grade 2. 3. Has diarrhea grade > 1 during screening period. 4. Has received chemotherapy, radiotherapy, targeted therapy, immunotherapy, or other systemic antitumor therapies within 14 days before the first dose. 5.
