简要总结
This Phase 1/2, first-in-human, open-label, multicenter study follows a 3+3 ascending dose escalation design to determine the MTD/RP2D and to characterize the safety, tolerability, PK, and antitumor effects of LNS8801 alone and in combination with pembrolizumab. The study will include a dose escalation phase, a dose expansion phase, and phase 2A cohorts. Up to 200 patients will be accrued for this study. Up to 15 study sites in the United States will participate in the study.
详细描述
In this Phase 1/2, first-in-human, open-label, multi-center study. Dose escalation cohorts enrolled at least 3 patients in accordance with a traditional dose escalation 3+3 design, and the study will determine the MTD/RP2D of LNS8801. LNS8801 will be administered orally 3 days/week or once or twice a day during 21 day cycles until disease progression or unacceptable toxicity occurs.
Safety assessments will be performed on all patients at screening, throughout their participation in the study, and for 30 days (90 days in combination cohorts) following the last dose of study drug. Throughout the study, imaging of tumors for evidence of tumor response and/or progression will be performed; biopsies will be performed on accessible lesions.
After the RP2D of LNS8801 is identified and the safety of dosing LNS8801 with pembrolizumab has been established, expansion cohorts and Phase 2A cohorts will open. Any 2 dose escalation cohorts may be expanded to 8 to 10 patients to include additional patients to further explore PK and PD.
Phase 1B expansion cohorts include a monotherapy cohort (LNS8801 alone) of melanoma patients (not uveal) who are now not eligible for additional anti-PD-1 therapy in the judgement of the investigator because of prior severe immune related adverse events and a combination therapy (LNS8801 + pembrolizumab) cohort in anti-PD-1/L1 refractory advanced cancer patients who have previously had clinical benefit on anti-PD-1/L1 therapy alone or in combination (complete response or partial response of any duration, or confirmed stable disease for at least 16 weeks) but have since relapsed and not had an intervening cytotoxic chemotherapy. Up to 28 evaluable patients may be studied in each cohort.
The study will also include the following 8 Phase 2A cohorts.

- •Inclusion Criteria for treatment portion of study:
- •Has histopathologically confirmed locally advanced or metastatic solid tumor cancer (or lymphoma in Phase 1). The solid tumor cancer is further defined in some cohorts as:
- •Phase 1B monotherapy expansion cohort:
- •Has melanoma, except uveal melanoma, and has previously received anti-PD-1/L1 therapy and is now not eligible for anti-PD-1 treatment in the judgement of the Investigator due to prior severe immune related adverse events, and has not received intervening cancer therapy since the anti-PD-1/L1 therapy.
- •Monotherapy Cohort M2:
- •Has pancreatic, gastric, non small cell lung cancer (NSCLC), or colorectal cancer.
- •Monotherapy Cohort M3:
- •Has cutaneous melanoma, and has previously received anti-PD-1/L1 therapy and is now not eligible for anti-PD-1 treatment in the judgement of the Investigator due to prior severe immune related adverse events, and has not received intervening cancer therapy since the anti-PD-1/L1 therapy.
- •Monotherapy Cohort M4:
- •Has any solid tumor malignancy, except cutaneous melanoma, and has previously received anti-PD-1/L1 therapy and is now not eligible for anti-PD-1 treatment in the judgement of the Investigator due to prior severe immune related adverse events, and has not received intervening cancer therapy since the anti-PD-1/L1 therapy.
- •Monotherapy Cohort M5:
- •Has metastatic uveal melanoma, and has received ≤ 2 prior lines of prior systemic therapy.
- •Phase 1B combination expansion cohort:
- •Has any locally advanced or metastatic solid tumor cancer, and has first had a clinical benefit from, followed by documented disease progression on an anti-PD-1/L1 treatment administered either as monotherapy or in combination. Clinical benefit is defined as a complete or partial response of any duration or stable disease for at least 16 weeks with at least one scan showing stable disease. Patients should not have received intervening therapy that did not include anti-PD1/L1 between finishing anti-PD-1/L1 treatment and commencing study treatment.
- •Disease progression on an anti-PD-1/L1 therapy is defined as both:
- •Having received anti-PD-1/L1 therapy at least twice if dosed every 4 weeks (q4w) or longer, at least 3 times if dosed every 3 weeks (q3w), or at least 4 times if dosed every 2 weeks (q2w) and,
- •Having documented clinical or radiographic progression of disease (PD) while on anti-PD-1/L1 therapy.
- •Combination Therapy Cohort C2:
- •Has pancreatic, gastric, NSCLC, or colorectal cancer.
- •Combination Therapy Cohort C3:
- •Has metastatic NSCLC expressing PD-L1 with a Tumor Proportion Score (TPS) ≥1% and ≤49% as determined by an FDA-approved test, and must not have EGFR or ALK genomic tumor aberrations or have demonstrated disease response on or following FDA-approved therapy for these aberrations, and is PD-1/L1 naïve, and is eligible for pembrolizumab as the standard of care or has no available standard of care.
- •Combination Therapy Cohort C5:
- •Has metastatic uveal melanoma and, has received ≤ 2 prior lines of prior systemic therapy.
- •Combination Therapy Cohort C6:
- •Has cutaneous melanoma.
- •Has no standard of care or the patient declines standard of care options.
