這是一項首次人體、開放標籤、多中心第一期研究，旨在評估 OP-3136（一種賴氨酸乙酰轉移酶 6A 及 6B（KAT6A/B）抑制劑）作為單藥治療及與其他抗癌藥物聯合使用於晚期實體瘤參與者的安全性、耐受性、藥物動力學（PK）、藥效學（PD）及初步療效。 本研究分為兩部分：劑量遞增部分（第一部分）及劑量擴展部分（第二部分）。
適應症：Advanced or Metastatic ER+ HER2- Breast Cancer (mBC)、Advanced or Metastatic Non-Small Cell Lung Cancer (NSCLC)、Advanced or Metastatic Castration-Resistant Prostate Cancer (mCRPC)、Metastatic Breast Cancer、Fulvestrant、Palazestrant
收案條件
納入條件
- Participants with advanced or metastatic ER+HER2- breast cancer, mCRPC, or NSCLC (Part 1) or advanced or metastatic ER+HER2- BC or mCRPC (Part 2).
- Part 1A (Dose escalation for OP-3136 monotherapy): Participants must have a tumor that is unresectable or metastatic and for which life prolonging measures do not exist or available therapies are intolerable or no longer effective.
- Part 1B (Dose escalation for OP-3136 in combination with fulvestrant): Participants with advanced or metastatic ER+ HER2- breast cancer that have progressed on or after at least 1 prior line of treatment that included endocrine therapy and CDK 4/6 inhibitor in advanced or metastatic setting and must have received no more than 2 prior lines of endocrine therapy (one of which must be in combination with CDK4/6 inhibitor) and no more than 1 prior line of chemotherapy or an antibody-drug conjugate in the advanced or metastatic setting.
- Part 1C (Dose escalation for OP-3136 in combination with palazestrant): Participants with advanced or metastatic ER+ HER2- breast cancer that have progressed on or after at least 1 prior line of treatment that included endocrine therapy and CDK 4/6 inhibitor in advanced or metastatic setting and must have received no more than 2 prior lines of endocrine therapy (one of which must be in combination with CDK4/6 inhibitor) and no more than 1 prior line of chemotherapy or an antibody-drug conjugate in the advanced or metastatic setting.
- Part 2A (Dose Expansion in ER+ HER2- mBC for OP-3136 monotherapy): Participants must have received up to 3 prior lines of endocrine therapy (one of which must be in combination with CDK4/6 inhibitor) and up to 1 prior line of chemotherapy or an antibody-drug conjugate.
- Part 2A (Dose Expansion in mCRPC for OP-3136 monotherapy): Participants must have received up to 4 lines of prior systemic therapy for prostate cancer. Prior therapy must include treatment with an androgen receptor pathway inhibitor(s).
- Part 2B (Dose Expansion in ER+ HER2- mBC for OP-3136 in combination with fulvestrant OR Dose Expansion in ER+ HER2- mBC for OP-3136 in combination with palazestrant): Participants must have progressed on or after at least 1 prior line of treatment that included endocrine therapy and CDK 4/6 inhibitor in advanced or metastatic setting. Participants must have received no more than 2 prior lines of endocrine therapy in the advanced or metastatic setting and no more than 1 prior line of chemotherapy or an antibody-drug conjugate in the advanced or metastatic setting.
排除條件
- Prior therapy with KAT6A/B inhibitor in any treatment setting.
- Participants with advanced/metastatic, symptomatic, visceral spread, that are at risk of life-threatening complications in the short term.
- Known active or symptomatic central nervous system (CNS) metastases, carcinomatous meningitis, leptomeningeal disease, or a spinal cord compression that require CNS-specific treatment, or participants who did not demonstrate clinical and radiologic stability during the last 2 months prior to the first dose of study treatment or require or are currently on steroid therapy for CNS metastases.
- History of cerebral vascular disease, including transient ischemic attack, within 6 months prior to the first dose of study treatment.
- History of or ongoing impaired cardiac function or clinically significant cardiac disease within 6 months prior to the first dose of study treatment.
