Study of REM-422 in Patients With Recurrent or Metastatic Adenoid Cystic Carcinoma
Study Details
Study Description
Brief Summary
The goal of this study is to determine the safety and antitumor effects of REM-422, a MYB mRNA degrader, in people with advanced Adenoid Cystic Carcinoma (ACC)
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1 |
Detailed Description
This is a Phase 1, open-label, non-randomized, multicenter study investigating REM-422, a potent, selective, and oral small molecule mRNA degrader that reduces expression of the MYB transcription factor for patients with recurrent or metastatic ACC.
This study includes a Dose Escalation Phase and a Dose Expansion Phase. The purpose of the Dose Escalation Phase is to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of REM-422 in patients with recurrent or metastatic ACC. The purpose of Dose Expansion is to further evaluate the safety and anti-tumor activity of the RP2D carried forward from Dose Escalation.
Participation in this study will continue until disease progression, therapy intolerance, or participant withdrawal.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: REM-422 Dose Escalation: Participants will receive escalating doses of REM-422 to determine Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D)-422, oral capsule administered once daily Dose Expansion: Participants will receive REM-422 at the identified RP2D Treatment will continue until disease progression, therapy intolerance, or participant withdrawal Safety evaluation will continue until 30 days of last administration of REM-422 |
Drug: REM-422
REM-422 is a first in class, small molecule mRNA inhibitor that reduces expression of the MYB transcription factor
REM-422 will be administered orally once daily

Outcome Measures
Primary Outcome Measures
- Frequency and severity of Treatment Emergent Adverse Events (TEAEs) [18 months]
Frequency and severity of Treatment Emergent Adverse Events (TEAEs) will be evaluated according to the NCI-CTCAE version 5.0 and number of participants with Dose Limiting Toxicities will be assessed to determine Safety and Tolerability of REM-422
- Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) [Assessed at the end of Cycle 1 for each participant]
Frequency and severity of Treatment Emergent Adverse Events (TEAEs) will be evaluated according to the NCI-CTCAE version 5.0 and the number of participants with Dose Limiting Toxicities will be assessed

Measure Area Under the Curve (AUC) of REM-422
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Be able to provide informed consent.
-
Be 18 or older at the time of informed consent.
-
Disease criteria:
-
Histologically confirmed ACC, any site of origin.
-
Have locally advanced or metastatic ACC.
-
Dose Escalation phase ONLY: Evidence of radiographic progression and/or signs and symptoms associated with their disease (eg, pain, dyspnea, reduced performance status). Participants who have stable disease while being treated with another agent that is not tolerated are eligible after the appropriate washout period.
-
Dose Expansion phase ONLY: Measurable disease at the time of enrollment. At least 1 measurable lesion according to RECIST v1.1 criteria. Participants must have radiographic evidence of disease progression by RECIST v1.1 criteria ≤ 6 months prior to study enrollment.
-

-
Be able to provide during Screening a tissue specimen of either a fresh biopsy of a non-target lesion or an archival tumor sample obtained within the last 6 months or longer if there has been no systemic interval therapy since the last biopsy.
