Clinical summary

Summary

This study aim to evaluate the efficacy of a combination of immunotherapy drugs (teclistamab and talquetamab) in treatment of functional high risk Multiple Myeloma. 

Eligible participants will be given each treatment drug for a maximum of 28 cycles. Each cycle is 28 days. 

Talquetamab will be given on days 1, 4, 8,15 of the first cycle in gradually increasing doses. From Cycle 2 to 24 participants will be given Talquetamab on days 1 and 15. 

Teclistamab will be given on days 1, 4, 8, 15 of the first cycle in gradually increasing doses. From Cycle 2 to 24 Teclistamab will be given only on day 1.  

Both drugs be given subcutaneously. 

Eligible participant must only have received only 1 prior therapy consisting of an IMID or PI-based induction regimen. 

Conditions

This trial is treating people with Functional High Risk Multiple Myeloma

Eligibility

Inclusion

- Age >= 18 years of age.
- Able to provide written consent.
- Documented diagnosis of MM with measurable disease as define by any of the following
- Serum M-component greater than 5 g per L and/or
- Urine M-component greater than200 mg per 24 h, and/or
- Involved serum free light chain level greater than 100mg per L.
- Patients who do not meet these criteria but have biopsy proven extra-medullary disease (extra-osseous plasmacytoma that is not contiguous with an osseous plasmacytoma) that can undergo response evaluation with serial PET-CT are considered to have measurable disease.
- Documented evidence of progressive disease within 18 months of commencing front-line therapy for newly diagnosed MM according to IMWG response criteria
- Patients must have received only 1 prior therapy consisting of an IMID or PI-based induction regimen with or without high dose melphalan conditioned autologous stem cell transplant +/- lenalidomide maintenance.
- No contraindication to the use of any of the study drugs and able to comply with trial requirements.
Adequate liver function (total bilirubin less than 2.0x upper limit of normal (ULN), alanine aminotransferase less than 5.0x ULN) unless considered secondary to MM.
- Absolute neutrophil count greater than or equal to 1.0 x 10^9 per L. Granulocyte colony-stimulating factor (G-CSF) therapy is permitted on study.
Platelet count greater than or equal to 50 x 10^9 per L (greater than or equal to 30 x 10^9 per L if MM involvement in the marrow is greater than 50 per cent), patients should not have received platelet transfusions within 7 days of the screening platelet count.
- Hb greater than or equal to 80 g per L, red cell transfusions as per institutional protocol are allowed.
- Has provided written informed consent.
- Women of childbearing potential participants must not become pregnant while on study; male participants must not father children while on study

Exclusion

-Patients who have had myocardial infarction within 6 months prior to enrolment, or New York Hospital Association Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, electrocardiographic evidence of acute ischemia or active conduction system abnormalities.
- Any other serious or uncontrolled medical or psychiatric illness that could, in the investigators’ opinion, potentially interfere with the completion of treatment according to this protocol.
- Known ongoing or active systemic infection, active hepatitis B or C infection, or known human immunodeficiency virus positivity. Patients with latent TB can proceed on study provided adequate prophylaxis has been commenced.
- Known autoimmune disease requiring ongoing immunosuppression
- Women who are pregnant or lactating. Women of child-bearing potential must have a negative pregnancy test (minimum sensitivity of at least 25 mIU per mL) at Screening.
- Active malignancy with the exception of any of the following:
o Adequately treated basal cell carcinoma, squamous cell carcinoma or in situ cervical cancer.
o Adequately treated stage 1 cancer from which the subject is currently in remission from and has been in remission for greater than 2 years.
o Stage 1 prostate cancer that does not require treatment.
o Any other cancer from which the subject has been disease-free for greater than 2 years.
- Presence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule. This condition must be discussed with the patient prior to signing consent and registration in the trial.
- Participation in other clinical trials for the treatment of MM, including those with other investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial
- Patients with pre-existing venous access, in the form of a PICC line or PORT (due to higher risk of bloodborne infections) that has not been replaced within the last 3 months and/or has a documented history of previous bacteraemia or potential line-related sepsis.
