Summary

This is a multicenter, open-label, dose-escalation and efficacy/safety Phase I/II study to assess RP2D, safety, tolerability and anti-tumor activity of Sintilimab + afuresertib + nab-paclitaxel or docetaxel administered as a combination therapy.

This study is designed to identify the MTD and recommended Phase II dose (RP2D) of afuresertib in combination with sintilimab and nab-paclitaxel or docetaxel, respectively, to characterize the PK profile of afuresertib in phase I and to evaluate clinical efficacy and safety of the combination therapy in phase II. The study population in phase II is the patients with one of the five selected cancers who resistant to the prior anti-PD-1/PL-1 treatments (as a monotherapy or in combination with other anti-cancer drugs including chemotherapy) , such as EC, GC/GEJC, EsC, CC, and NSCLC.

Description

This is a multicenter, open-label, dose-escalation and efficacy/safety Phase I/II study to assess RP2D, safety, tolerability and anti-tumor activity of Sintilimab + afuresertib + nab-paclitaxel or docetaxel administered as a combination therapy. This study is designed to identify the MTD and recommended Phase II dose (RP2D) of afuresertib in combination with sintilimab and nab-paclitaxel or docetaxel, respectively, to characterize the PK profile of afuresertib in phase I and to evaluate clinical efficacy and safety of the combination therapy in phase II. The study population in phase II is the patients with one of the five selected cancers who resistant to the prior anti-PD-1/PL-1 treatments (as a monotherapy or in combination with other anti-cancer drugs including chemotherapy) , such as EC, GC/GEJC, EsC, CC, and NSCLC.

For phase I, the MTD is defined as the combination dose level with a DLT rate that is closest to the target toxicity rate (0.3). Patients in each dose level are planned to be enrolled in each cohort of size 3 and maximum to 9. Totally there would be no more than 42 cases in 2 combination groups (maximum 21 patients for each combination group). RP2D evaluation will be based on the observed safety profiles,PK ,PK was analyzed on 3-9 patients per dose of albumin-paclitaxel and docetaxel (pk Sample collection may be less than 3 if the group was discontinued due to DLT observed) . The dose escalation decision will be made based on the observed safety profiles of the tested combined doses and reviewed by the safety committee. The recommended combined dose level will be as follows based on BOIN dose escalation design.

Once the RP2D of Sintilimab + afuresertib + nab-paclitaxel or docetaxel has been established, a cohort consisting of 50-125 patients with stratifying for each cancer type (10 -25 patients for each cancer type) who resistant to anti-PD-1/PD-L1 or its combination therapy (except for CC and EC, who did not receive prior anti-PD-1/PD-L1 could be enrolled.

The preliminary anti-tumor efficacy of Sintilimab + afuresertib + nab-paclitaxel or docetaxel therapy will be assessed by the measurement of ORR, PFS, OS, DOR, DCR based on the tumor assessment in each of the five solid tumors. Patients with biomarkers, such as PTEN/PI3K/AKT alternations, will be analysed retrospectively as the subpopulations for their anti-tumor efficacy in each cancer type.

received <=3 lines systematic therapy during recurrent/metastatic period
Tumor diagnosis
In phase I, patients had a histology confirmed diagnosis of locally advanced or metastatic solid tumors who had at least 1 prior systemic anti-cancer treatment including neoadjuvant/adjuvant therapy are qualified to be enrolled. The patients with the 5 selected cancer types below who resistant to prior anti-PD-1/PL-1 or its combination therapies will be enrolled with a higher priority
In phase II, the patients have only the following diagnoses will be allowed
CC: Patients with histologically confirmed metastatic, recurrent or persistent squamous cell carcinoma, adenosquamous carcinoma, adenocarcinoma of the cervix are allowed. The other histological types of cervical cancer will be excluded
EC: Patients with histologically confirmed metastatic, recurrent or persistent Epithelial Endometrial Carcinoma with endometrioid, high grade serous, or clear cell carcinoma. The other histological types of endometrial cancer will be excluded

NSCLC: Patients with histologically confirmed locally advanced, recurrent, or metastatic Non-Small Cell Lung Cancer (squamous cell carcinoma or adenocarcinoma, adenosquamous carcinoma), who have EGFR wild type status, KRAS wild type status and ALK- negative rearrangement status
GC/GEJC: Patients with histologically confirmed locally advanced, recurrent, or metastatic Her2- gastric adenocarcinoma or gastroesophageal junction adenocarcinoma or squamous cell carcinoma allowed
Biomarker test
In phase I, the biomarker test with tumor sample is optional. However, blood test of cfDNA is required
In phase II, if patient has prior tumor sample PTEN/PI3K/AKT gene alterations or immunohistochemistry test with a report, no further tumor sample biomarker test is needed, but the blood cfDNA test is still required in this study. Otherwise, patient should be able to provide archival or biopsy tumor samples for PTEN immunohistochemistry and PTEN/PI3K/AKT gene alterations, and/or the blood sample for PTEN/PI3K/AKT gene alterations for the cell-free DNA (cfDNA) test. The archival tumor tissue sample obtained better within 2 year from study enrollment or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated will be accepted for IHC test and gene sequencing test. Formalin-fixed, paraffin embedded tissue blocks are preferred to be sectioned on the slides
Please contact sponsor if patient cannot provide archival or biopsy tumor samples
