Evaluation of DLT of CHS-388 as a monotherapy.
ORR will be estimated by the percentage of patients achieving a best overall response of CR or PR per RECIST v1.1 and iRECIST.
Evaluation of DLT of CHS-388 in combination with pembrolizumab.
Safety and tolerability of CHS-388 + pembrolizumab will be assessed by summarizing AEs and will be based on TEAEs. A TEAE is an AE that emerges or worsens in the period from the first dose of study treatment to 30 days after the last dose of study drug assessed by per CTCAE version 5.0 or higher.
ORR will be estimated by the percentage of patients achieving a best overall response of CR or PR per RECIST v1.1 and iRECIST.

| Part A Monotherapy Dose Escalation | EXPERIMENTAL | The Part A monotherapy dose escalation portion of the study will evaluate the safety, tolerability, PK, pharmacodynamics, and preliminary efficacy of CHS-388 as monotherapy in up to 30 patients with advanced solid tumors. |
| Part B CHS-388 Monotherapy Expansion | EXPERIMENTAL | Part B monotherapy expansion will evaluate the safety, tolerability, PK, pharmacodynamics, and efficacy of CHS-388 monotherapy at the recommended phase 2 dose (RP2D) in up to 40 patients with ccRCC, up to 40 patients with HCC, and up to 40 patients with NSCLC. |
| Part C CHS-388 in Combination with Pembrolizumab | EXPERIMENTAL | Part C will evaluate the safety, preliminary efficacy, tolerability, and PK of CHS-388 in combination with pembrolizumab in patients with advanced RCC or HCC, or anti-PD(L)1 relapsed/refractory advanced NSCLC. |
| Part D CHS-388 in Combination with Toripalimab | EXPERIMENTAL | Part D will evaluate the safety, preliminary efficacy, tolerability, and PK of CHS-388 in combination with toripalimab in patients with anti-PD(L)1 relapsed/refractory advanced NSCLC. |

| CHS-388 | DRUG | CHS-388 is a fully human IgG1 antibody against IL-27. Inhibition of IL-27 with CHS-388 reduces STAT1 phosphorylation leading to increased pro-inflammatory (anti-tumor) cytokine secretion (e.g., IFN-g, TNF-a) and decreased expression of inhibitory immune checkpoint receptors (e.g., PD-L1, TIGIT, LAG3) on immune cells that may result in anticancer therapeutic activity. |
| Pembrolizumab | DRUG | Pembrolizumab by intravenous (IV) infusion |
| Toripalimab | DRUG | Toripalimab by IV infusion |

CHS-388 is an investigational small molecule being studied for the treatment of advanced solid tumors, including clear cell renal cell carcinoma, hepatocellular carcinoma, and non-small cell lung cancer. It is currently in Phase 1 clinical development and has not been approved by the FDA.
CHS-388 is being developed by Coherus Oncology, Inc., a subsidiary of Coherus BioSciences, Inc. (NASDAQ: CHRS). The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with advanced solid tumors.
CHS-388 is in Phase 1 clinical development. A Phase 1 study of the drug has been completed, involving 145 patients with advanced solid tumors. The drug is investigational and has not received FDA approval.
CHS-388 has been studied in a completed Phase 1 clinical trial with the identifier NCT04374877. This trial enrolled 145 patients with advanced solid tumors, including clear cell renal cell carcinoma, hepatocellular carcinoma, and non-small cell lung cancer, across the United States, Singapore, and South Korea.
Yes, CHS-388 was formerly known as SRF388. The clinical trial NCT04374877, titled 'Study of CHS-388 (Formerly Known as SRF388) in Patients With Advanced Solid Tumors,' confirms that these names refer to the same investigational drug.
