clinical data - MajesTEC-1 STUDY

MajesTEC-1 (NCT03145181; NCT04557098) is evaluating the safety and efficacy of TECVAYLI in patients with RRMM.¹

Study Design/Methods

The main objectives are as follows: part 1 (dose escalation) to determine the RP2D for TECVAYLI; part 2 (dose expansion) to distinguish safety and tolerability at the RP2D; and part 3 (the phase 2 component) to evaluate the efficacy of TECVAYLI at the RP2D.^1,24

Cohort A Safety Results

Moreau et al (2022)^1,2 published safety and efficacy results of patients receiving TECVAYLI in the MajesTEC-1 study at a median follow-up of 14.1 months (range, 0.3-24.4).

• A total of 68 deaths (41.2%) were reported:
  • Progressive disease: 41 deaths (24.8%)
  • AEs unrelated to TECVAYLI: 14 deaths (8.5%; COVID-19, n=10 [6.1%]); pneumonia, n=1 [0.6%]; hemoperitoneum, n=1 [0.6%]; pseudomonal pneumonia, n=1 [0.6%]; and hypovolemic shock, n=1 [0.6%])
  • AEs considered by the investigator to be related to TECVAYLI: 5 deaths (3.0%; COVID-19, n=2 [1.2%]; hepatic failure, n=1 [0.6%]; streptococcal pneumonia, n=1 [0.6%]; progressive multifocal leukoencephalopathy, n=1 [0.6%])
  • Other causes: 8 deaths (4.8%; unknown, n=2 [1.2%]; respiratory failure due to pneumonia, n=1 [0.6%]; trauma after fall, n=1 [0.6%]; sepsis/bronchopneumonia/MM, n=1 [0.6%]; COVID-19, n=1 [0.6%]; presumed pneumonia, but not clinically diagnosed as such, n=1 [0.6%]; left pneumonitis complicated by multi-visceral failure, n=1 [0.6%]).
    • Other cause deaths were not considered treatment emergent because these patients died after subsequent myeloma therapy was initiated.

Nooka et al (2024)³ published the incidence, timing, and management of infections in patients receiving TECVAYLI in the MajesTEC-1 study at a median follow-up of 22.8 months (range, 0.3-33.6).

• A total of 21 deaths (12.7%) were reported due to infections: COVID-19 (n=18), bilateral pneumonia (unknown pathogen; n=1), pneumococcal pneumonia (n=1), and progressive multifocal leukoencephalopathy (PML; n=1).
  • One patient (0.6%) who died from PML after 16.1 months had discontinued TECVAYLI treatment 2.5 months earlier due to grade 4 PML.
• Most patients were enrolled before COVID-19 vaccines were available. Once the COVID-19 vaccine was available, 60% of patients (n=99) received at least one dose, including 13/18 patients who died from COVID-19 (12 received all doses after starting TECVAYLI; one received 2 doses prior then a third dose during TECVAYLI treatment).
  • Patients who were unvaccinated tended to die earlier (0.7-5.9 months; between January 2021 and November 2021 [n=6]) than vaccinated patients (4.3-25.9 months; between April 2021 and December 2022 [n=12]).
  • At the time of death, 13/18 patients had partial response or better (≥PR) and 2/18 had stable disease (3 deaths were reported before any post-baseline efficacy assessments).
• Deaths due to respiratory infections were reported in 2 patients (1.2%); 1 after 1.9 months (bilateral pneumonia, pathogen unknown) and 1 after 10.6 months (pneumococcal pneumonia).

van de Donk et al (2024)^4,5 conducted a post hoc analysis that evaluated the potential impact of COVID-19 on outcomes in patients receiving the RP2D of TECVAYLI in the MajesTEC-1 study (data cutoff date January 4, 2023). Of note, MajesTEC-1 recruitment occurred concurrently with the pandemic, starting in March of 2020. COVID-19 vaccines were not approved until late 2020 to early 2021, approximately 9 months into MajesTEC-1 enrollment.

Methods

• Infections were managed per institutional guidelines and/or TECVAYLI interruption; vaccination (including booster doses) was recommended per availability.
• Patients with grade 5 COVID-19 infection were censored at the time of last disease evaluation for analyses of progression-free survival (PFS; n=17) and duration of response (DOR) (n=13) if death occurred without disease progression. All patients who died from COVID-19 (n=18) were censored at the time of death for analysis of overall survival (OS).

Safety Results

• Any-grade and grade 3/4 COVID-19 infection was reported in 29.1% (n=48) and 21.2% (n=35) of patients, respectively, and deaths due to COVID-19 infection were reported in 10.9% (n=18) of patients; 4 deaths from COVID-19 were considered by the investigators to be related to TECVAYLI treatment.
• A total of 7.9% of patients (n=13), including 1/18 patients who died of COVID-19, were vaccinated at least once with a COVID-19 vaccine before TECVAYLI was administered. The patient who died received 2 doses before starting TECVAYLI.
• A total of 60% of patients (n=99), including 13/18 patients who died of COVID19, were vaccinated at least once with a COVID-19 vaccine on study overall (1 dose, n=3; 2 doses, n=4; 3 doses, n=3; 4 doses, n=3 [the patient who was vaccinated pre-TECVAYLI received their 3^rd dose on-study]).
• Patients who never received a COVID-19 vaccination tended to die of COVID-19 earlier during TECVAYLI treatment (range, 0.7-5.9 months) compared to patients who received ≥1 COVID-19 vaccination (range, 2.4-25.9 months). A greater proportion of deaths were reported in 2021 (5/5 vs 5/13 respectively) compared to 2022 (0/5 vs 8/13, respectively).

Costa et al (2024)⁶ presented a subgroup analysis evaluating the safety and efficacy outcomes in patients with HR features from the MajesTEC-1 study.

• At a data cutoff of Aug 22, 2023, a total of 94 deaths (57%) were reported in the overall RP2D population. Details on deaths in patients with HR features are provided in Table: MajesTEC-1 (Cohort A): Mortality in Patients With HR Features.

Cohort C Safety Results

Touzeau et al (2024)⁷ published the safety and efficacy of TECVAYLI in cohort C of the MajesTEC-1 study at a median follow-up of 28.0 months (range, 0.7-31.1).

• A total of 25 deaths (62.5%) were reported. Disease progression was the primary cause of death in 12 patients (30.0%). Two patients (5.0%) died due to events that investigators considered were related to TECVAYLI treatment (COVID-19, n=1; cardiac arrest, n=1). Of the 10 patients with grade 5 TEAEs:
  • A total of 8 patients (20.0%) died due to AEs (COVID-19 [n=4; 10%], and 1 patient each [2.5%] due to cardiac arrest, cardiac failure, coronary artery dissection, and sudden death).
  • The other 2 grade 5 AEs were due to disease progression. The patient who suffered cardiac arrest had pneumonia that began 10 days prior to death.

Prophylactic Tocilizumab Cohort Safety Results

van de Donk et al (2024)⁸ presented the effects of prophylactic tocilizumab for the reduction of CRS in patients treated with TECVAYLI in the prophylactic tocilizumab cohort of the MajesTEC-1 study at a median follow-up of 8.1 months (range, 0.9-13.2).
