Overview
Brief Summary
The goal of this clinical trial is to test the safety, tolerability, and efficacy of TG01 vaccination in patients with KRAS or NRAS mutation on codon 12/13 mutation who has multiple myeloma or high-risk smoldering multiple myeloma. The main question it aims to answer are:
Is TG01/QS-21 vaccination safe and tolerable for this patient group? Is TG01/QS-21 vaccination treatment efficient in this group in terms of increased overall response rate, overall survival rate, progression-free survival, and time til next treatment? Is there an immunological response to the vaccine? Participants will be given TG01/QS-21 vaccination treatment. Treatment consists of 12 doses of TG01/QS-21 vaccine given every two weeks in the first 12 weeks, followed by every eight weeks until week 52.

Arms & Interventions
TG01
TG01 is a sterile lyophilizate consisting of a mixture of seven peptides. The finished product is a white powder for injection, consisting only of the active substances containing 2.1 mg of peptides (individual peptides comprising 0.3 mg each). The lyophilizate is to be reconstituted with QS-21 for injection before use. QS-21 is a naturally occurring saponin molecule purified from the South American tree Quillaja saponaria Molina. QS-21 Solution is supplied in a 2 mL CZ resin vial as a sterile, solution in PBS (phosphate buffered saline) at a concentration of 0.5 mg/mL QS-21 (500 mcg/mL) with each vial containing 0.7 mL intended single use only. The vaccine will be given subcutaneously Treatment consists of 12 doses TG01/QS-21 vaccine given every 2 weeks in the first 12 weeks, followed by every 8 weeks until week 52. TG01 dose 0.7 mg dose and QS-21 50 ug.
Intervention: TG01
Outcomes
