S095035 as a Single Agent and in Combination in Adult Participants With Advanced or Metastatic Solid Tumors With Deletion of MTAP

Running, not enrolling · Phase 1/Phase 2

Conditions studied: MTAP-deleted Solid Tumors

In brief

This is a first-in-human Phase 1/2, multicenter, open-label study of S095035 as single-agent, or in combination with TNG462 in adult participants with advanced or metastatic solid tumors with homozygous deletion of MTAP who have failed to respond to or have progressed after at least 1 prior treatment regimen, and for whom additional effective standard treatment is not available. S095035 is an oral methionine adenosyltransferase 2A \[MAT2A\] inhibitor. TNG462 is a protein arginine N-methyltransferase 5 \[PRMT5\] inhibitor.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Estimated life expectancy ≥3 months.
• ECOG PS 0-1
• Participants able to comply with highly effective method of birth control requirements.
• Participants with histologically confirmed advanced or metastatic solid tumor's (excluding central nervous system tumors other than IDHwt glioblastoma), with measurable disease as per RECIST 1.1 or RANO 2.0 criteria for participants with IDHwt glioblastoma, that have progressed after at least one prior treatment regimen given for advanced/metastatic disease, and for whom additional effective standard therapy is not available. Patients in China with IDHwt glioblastoma will not be included.
• Participants with pre-existing documented MTAP homozygous gene deletion in their tumor tissue, determined using a next generation sequencing in vitro diagnostic test prior to screening.
• Phase 1 only - Participants (except IDHwt glioblastoma) willing to undergo paired fresh biopsy (pre-treatment and on-treatment) procedure. Exceptions may be made for feasibility and safety concerns. IDHwt glioblastoma must provide archival tissue from most recent surgery or biopsy.
• Adequate organ functions.
• Phase 2 only - Participants in dose expansion, except those with IDHwt glioblastoma, must provide newly collected tumor biopsies at screening. If not medically feasible archival tissue may be used, provided it was collected within 3 months before study entry and no treatment has been received since the most recent biopsy.
• Phase 2 only - Participants with IDHwt glioblastoma must provide archival tissue from their most recent surgery or biopsy, collected before screening.
• Phase 2 only - Participants in China who are to be considered for enrollment in the single agent dose expansion Arms and who have a pre-existing, documented cyclin-dependent kinase inhibitor 2A (CDKN2A) homozygous gene deletion in their tumor tissue (confirmed by an NGS IVD test), but do not have homozygous MTAP deletion reported, will need to be pre-screened to confirm homozygous MTAP deletion. Pre screening for homozygous MTAP deletion will be conducted using a central NGS IVD test using an archival tumor tissue, preferably the most recent and not older than 3 years.
• Phase 2 Arm 1a only - Participants with histologically or cytologically confirmed metastatic or unresectable locally advanced NSCLC with homozygous deletion of MTAP, with measurable disease as per RECIST version 1.1, who have progressed or experienced disease recurrence during or after at least 1 prior line of standard-of-care systemic therapy in the advanced/metastatic setting.
• Phase 2 Arm 1b only - Participants with histologically or cytologically confirmed metastatic or unresectable locally advanced BTC with homozygous deletion of MTAP, who have progressed or experienced disease recurrence during or after at least 1 prior line of standard-of-care systemic therapy in the advanced/metastatic setting.
• Phase 2 Arm 1c only - Participants with histologically or cytologically confirmed metastatic or unresectable locally advanced PDAC with homozygous deletion of MTAP, who have progressed or experienced disease recurrence during or after at least 1 prior line of standard-of-care systemic therapy in the advanced/metastatic setting.
• Phase 2 Arm 1d only - Participants with any other locally advanced or metastatic malignancies with homozygous deletion of MTAP, who have received and progressed of experienced recurrence during or after receiving at least 1 prior line of standard-of-care systemic therapy in the advanced/metastatic setting.
• Phase 2 Arm 2a only - Participants with histologically or cytologically confirmed metastatic or unresectable locally advanced BTC with homozygous deletion of MTAP, who have progressed or experienced disease recurrence during or after receiving at least 1 prior line of standard-of care systemic therapy in the advanced/metastatic setting.
• Phase 2 Arm 2b only - Participants with histologically or cytologically confirmed metastatic or unresectable locally advanced gastroesophageal cancer with homozygous deletion of MTAP, who have progressed or experienced disease recurrence during or after receiving at least 1 prior line of standard-of-care systemic therapy in the advanced/metastatic setting.
• Phase 2 Arm 2c only - Participants with histologically or cytologically confirmed metastatic or unresectable locally advanced PDAC with homozygous deletion of MTAP, who have progressed or experienced disease recurrence during or after receiving at least 1 prior line of standard-of-care systemic therapy in the advanced/metastatic setting.
