Brief Summary:

Part 1: Dose Escalation. The primary objective of Part 1 of this study is to evaluate the safety and tolerability of KB-0742 in participants with relapsed or refractory (R/R) solid tumors or non-Hodgkin lymphoma (NHL).

Part 2: Cohort Expansion. The primary objective of Part 2 of this study is to further evaluate the safety and tolerability of KB-0742 in defined participant cohorts.

Arm Intervention/treatment
Experimental: Part 1: Dose Escalation
Sequential cohorts of participants will receive escalating doses of KB-0742.
Drug: KB-0742
Oral capsules

Experimental: Part 2: Cohort Expansion

Following identification of the maximally tolerated dose (MTD) / recommended Phase 2 dose (RP2D) in Part 1, the following expansion cohorts will be enrolled:

Cohort A: Relapsed or refractory (R/R) solid tumors with evidence of MYC amplication/overexpression.

Cohort B: Relapsed or refractory (R/R) soft tissue sarcomas with evidence of transcription factor dysregulation.

Drug: KB-0742
Oral capsules

Secondary Outcome Measures :
  1. Part 1: Maximal Plasma Concentration (Cmax) of KB-0742 [ Time Frame: Cycle 1 Day 1 through Cycle 2 Day 1, where a cycle is up to 28 days ]
  2. Part 2: Maximal Plasma Concentration (Cmax) of KB-0742 [ Time Frame: Cycle 1 Day 1 and Cycle 1 Day 10, where a cycle is up to 28 days ]
  3. Part 1: Time to Maximal Plasma Concentration (Tmax) of KB-0742 [ Time Frame: Cycle 1 Day 1 through Cycle 2 Day 1, where a cycle is up to 28 days ]
  4. Part 2: Time to Maximal Plasma Concentration (Tmax) of KB-0742 [ Time Frame: Cycle 1 Day 1 and Cycle 1 Day 10, where a cycle is up to 28 days ]
  5. Part 1: Area Under The Plasma Concentration x Time Curve From Hour 0 to The Last Measurable Time Point (AUC0-last) of KB-0742 [ Time Frame: Cycle 1 Day 1 through Cycle 2 Day 1, where a cycle is up to 28 days ]
  6. Part 2: Trough Concentration (Ctrough) of KB-0742 [ Time Frame: Cycle 1 Day 1 and Cycle 1 Day 10, where a cycle is up to 28 days ]
  7. Part 1 and Part 2: Progression Free Survival (PFS) [ Time Frame: Cycle 1 Day 1 up to 30 days after the last dose, where each cycle is up to 28 days (up to approximately 38 months) ]
  8. Part 1 and Part 2: Disease Control Rate [ Time Frame: Cycle 1 Day 1 up to 30 days after the last dose, where each cycle is up to 28 days (up to approximately 38 months) ]
  9. Part 1 and Part 2: Duration of Disease Control [ Time Frame: Cycle 1 Day 1 up to 30 days after the last dose, where each cycle is up to 28 days (up to approximately 38 months) ]
  10. Part 1 and Part 2: Overall Response Rate (ORR) [ Time Frame: Cycle 1 Day 1 up to 30 days after the last dose, where each cycle is up to 28 days (up to approximately 38 months) ]
  11. Part 1 and Part 2: Duration of Response (DOR) [ Time Frame: Cycle 1 Day 1 up to 30 days after the last dose, where each cycle is up to 28 days (up to approximately 38 months) ]
