About this trial

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.

Trial outcomes

Primary outcomes

1

Percentage of participants with adverse events (AEs)

An Adverse Event is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.

Time frame
Baseline until 30 days after last dose of study drug, up to approximately 3 years
2

Percentage of participants discontinuing treatment secondary to treatment-related adverse events

Percentage of participants discontinuing treatment secondary to treatment-related adverse events

Time frame
Up to approximately 3 years

Secondary outcomes

1

Number of patients with Progression Free Survival (PFS)

defined as the time from study treatment start to disease progression for every patient

Time frame
Baseline to 11 years
2

Concentration of TG01-specific T-cell specific cytokine production

The immune response to TG01 will be measured by IFNg/TNFa ELISPOT or FluoroSpot quantifying the TG01 T-cell specific cytokine production. A positive immune response will be defined as a 2-fold higher mean spot number in experimental wells (with vaccine peptides) compared to control wells (medium)

Time frame
Baseline until end of study, assessed up to 11 years
3

Overall response rate per patient

The proportion of patients who achieve partial response (PR) or better following at least one dose of study treatment

Time frame
Baseline to approximately 3 years
4

Overall Survival (OS) per patient

The OS rate of patients receiving 1 or more study treatments

Time frame
Baseline until the end of study, assessed up to 11 years
