Brief Summary

An Open, Multi-Center Phase I/II Clinical Study To Evaluate The Safety, Tolerability, Pharmacokinetic Characteristics And Effectiveness Of KL590586 Capsules In Patients With Advanced Solid Tumors Carrying RET Fusion Or Mutant Genes

Detailed Description

This is an open, multicentre phase I/II study. To evaluate the safety, tolerability, pharmacokinetic/pharmacodynamic properties and efficacy of KL590586 in patients with advanced NSCLC, MTC and other solid tumours carrying a RET fusion or mutation gene. Phase I of this study includes a dose-escalation phase and a dose-expansion phase (as needed), which will focus on exploring MTD and/or RP2D of KL590586 in patients with advanced solid tumours; Phase II will assess the efficacy and safety of KL590586 in different cohorts (NSCLC, MTC and other tumour types carrying RET fusions or mutations) of solid tumour patients at the RP2D dose.

7. Able to understand and voluntarily sign an informed consent form, and be able to comply with the visit and related procedures stipulated in the plan

Exclusion Criteria

1. There are known major driver gene changes other than RET. For example, NSCLC carrying targeted mutations such as EGFR, ALK, ROS1 or BRAF; colorectal cancer carrying mutations such as oncogenic KRAS, NRAS or BRAF. If the patient has a co-mutation, the investigator should discuss with the sponsor whether the patient can be included in the group

2. Symptomatic primary central nervous system (CNS) tumors, brain metastases, leptomeningeal carcinogenesis, or untreated spinal cord compression that the researchers believe require local intervention

3. People with other active malignant tumors (except for non-melanoma skin cancer in situ, cervical cancer in situ and other localized tumors that have been cured and have not recurred within 5 years)

4. Need to use drugs known to be potent inhibitors or inducers of CYP3A4, drugs known to prolong QTc, and the treatment cannot be terminated at least 14 days before the study drug is administered

5. Received the following anti-tumor treatments: a) The previous anti-tumor drug treatment (except immunotherapy or other antibody therapy) is less than 14 days or 5 half-lives (whichever is longer) from the first treatment with study drug; b) In Those who have received any immunotherapy or other antibody treatment within 28 days before the first study drug administration; c) Those who have received more than 30% of bone marrow radiation or wide-range radiotherapy within 28 days before the first study drug treatment (the patients receiving palliative radiotherapy are the first Within 7 days before receiving study drug treatment)

6. Received major surgical operations within 28 days before receiving the first study drug treatment (excluding operations such as central venous catheter placement, tumor biopsy, and gastric tube placement)

7. Those who have received other clinical trial drug treatment within 28 days before receiving the first study drug treatment

8. Any original symptoms that may interfere with the results of the study, including: any unrecovered toxicity above grade 1 of the CTCAE related to previous anti-tumor therapy (hair loss and grade 2 neuropathy related to previous platinum-based drug treatment, etc.) Except for chronic toxicity judged by the person

9. Patients with clinically active interstitial lung disease, active pneumonia, and radiation pneumonia requiring treatment, or those who have been found or suspected of having such diseases during the screening period

10. Poorly controlled pleural effusion, abdominal effusion, or pericardial effusion after intervention (such as drainage)
