PCSK9 Inhibitor and PD-1 Inhibitor in Patients With Metastatic, Refractory To Prior Anti PD-1 Non-small Cell Lung
A Phase II Study of PCSK9 Inhibitor Alirocumab and PD-1 Inhibitor Cemiplimab in Patients With Metastatic, Refractory To Prior Anti PD-1 Non-small Cell Lung Cancer: TOP2201
Source: ClinicalTrials.gov · Last updated 4 Nov 2026
Brief summary (registry, in English)
PCSK9 mediates immune checkpoint blockade resistance by downregulating tumor cell surface MHC class 1 molecules. This study will evaluate if combining the anti-PCSK9 antibody alirocumab with the anti-PD-1 antibody cemiplimab can generate anti-tumor activity and clinical responses in patients with metastatic lung cancer who have progressed on first line immune checkpoint blockade therapy.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Prior treatment with PCSK9 inhibitors
- Major surgery less than 4 weeks prior to study enrollment
- Intolerance to prior PD-1/L1 treatment including discontinuation for severe or recurrent severe toxicity (including myocarditis or other myocardiotoxity, encephalitis, colitis, diarrhea, pancreatitis, hypo/hyperthyroidism, hypopituitarism, adrenal insufficiency, rash, autonomic neuropathy, myasthenia gravis, Guillain-Barre, myositis/polymyositis, hepatitis, Type 1 Diabetes, thrombocytopenia) or developed an immune checkpoint blockade related immune adverse event that was refractory to steroids and required additional systemic immunosuppressive medication.
Other illness
- Cardiac issues including MI, uncontrolled arrhythmia, symptomatic angina pectoris, active ischemia, or cardiac failure not controlled by medications.
- Another malignant condition diagnosed within 3 years of study enrollment
- Known history of HIV seropositivity or known acquired immunodeficiency syndrome (AIDS)
Lab values
- Uncontrolled diabetes mellitus, defined as HbA1c \> 10
Other
- Additional exclusion criterion as per listed in the protocol
Who the study is looking for

- If molecularly altered NSCLC including EGFR, ALK, ROS1, MET exon 14, RET, BRAF, NTRK, progression on prior targeted therapy is required
- Measurable disease by RECIST 1.1
- ECOG Performance Status 0 or 1
- Signed written informed consent
- Minimum of 4 weeks from any other experimental anti-cancer therapies or prior PD-1 treatment
- Meet all the laboratory criteria per protocol
