Brief Summary

This is a First-in-Human, Open Label, Phase I/II Study to Evaluate the Safety, Tolerability and Pharmacokinetics of HH2710 in Patients with Advanced Tumors, composed of a Phase I dose escalation and dose expansion stage and a Phase II dose extension stage.

Detailed Description

HH2710 is developed by Shanghai Haihe Pharmaceutical Co., Ltd. HH2710 is a highly potent, selective, reversible, ATP-competitive ERK1/2 inhibitor. This is a first-in-human study of HH2710 and is designed as an open-label, multicenter, Phase I/II study which is composed of a Phase I dose escalation and dose expansion stage and a Phase II dose extension stage.

Conditions

Advanced Tumors; Melanoma; Non-Small-Cell Lung Cancer; Erdheim-Chester Disease; Other RAS/RAF/MEK/ERK Mutated Tumors

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Dose escalation study of HH2710

to determine the MTD of HH2710 and/or Recommended Phase II dose (RP2D).

Group Type: EXPERIMENTAL

HH2710

Intervention Type: DRUG

HH2710 is a small molecule that potently inhibits both ERK1 and ERK2 protein kinases in the nanomolar range. The kinase selectivity assessment towards a panel of over 400 protein kinases showed that HH2710 barely inhibited other kinases at a concentration up to 1 μM, except the substantial inhibition against ERK1 (MAPK1), ERK2 (MAPK2) and the MAPK pathway upstream kinases MEK and RAF proteins.

Eligibility Criteria

Inclusion Criteria

1. Provide signed and dated informed consent prior to initiation of any study-related procedures.

2. Male or female patients aged ≥ 18 years.

3. Phase I dose escalation stage: Patients who have been diagnosed with histologically or cytological documented, unresectable/metastatic tumors that are refractory or intolerant to standard therapy or for whom no curative standard therapy exists.

• For LCH/ECD: Eligible patients must have multifocal disease and the diagnosis must be confirmed by pathological evaluation of the affected tissue.

4. Phase I expansion stage and Phase II stage: Histologically or cytologically documented unresectable/metastatic tumors with evidence of genetic mutations affecting MAPK pathway is required. Patients with a BRAF V600 mutation must have progressed on or after standard therapy, including BRAF and/or MEK inhibitors (≤3 lines). Patients entering the Phase 2 portion of the trial will be enrolled in Cohorts 1-4 depending upon their tumor type.

• Cohort 1: Patients with BRAF/NRAS (mutation sites as follows: NRAS G13V, NRAS Q61, BRAF V600, BRAF G469A, L485W, L597Q, T599dup) mutated melanoma;
• Cohort 2: Patients with BRAF/NRAS (mutation sites as follows: NRAS G13V, NRAS Q61, BRAF V600, BRAF G469A, L485W, L597Q, T599dup) mutated non-small cell lung cancer;
• Cohort 3: Patients with BRAF V600 mutated Langerhans Cell Histiocytosis Syndrome (LCH)/ Erdheim-Chester disease (ECD);
• For LCH/ECD: Eligible patients must have multifocal disease and the diagnosis must be confirmed by pathological evaluation of the affected tissue.
• Cohort 4: Patients with RAS/RAF/MEK/ERK mutated tumor types that are not included in other cohorts.

5. Patients in the Phase I dose escalation portion of the trial may have measurable (per RECIST v1.1) or evaluable disease. Patients in the Phase I expansion and Phase II portions of the trial must have measurable disease per RECIST v1.1.

6. Eastern Cooperative Oncology Group (ECOG) performance status≤1.
