➢ Correlate CYP3A4 Gene Single Nucleotide Polymorphisms (SNPs) to Side Effects of Using Crizotinib to Treat Non-Small Cell Lung Cancer (NSCLC), via Testing Peripheral Blood DNA.  
The detailed methods:
1) Detect each drug target whole gene precision sequence of everyone patient for all 600-recruited double-blind NSCLC patients.  
➢ Oxford Nanopore Technologies Ltd - Nanopore DNA Sequencing uses electrophoresis to transport an unknown sample through an orifice of 10−9 meters in diameter. A nanopore system always contains an electrolytic solutions- when a constant electric field is applied, an electric current can be observed in the system. The magnitude of the electric current density across a nanopore surface depends on the nanopore's dimensions and the composition of DNA or RNA that is occupying the nanopore. Sequencing is made possible because, when close enough to nanopores, samples cause characteristic changes in electric current density across nanopore surfaces. The total charge flowing through a nanopore channel is equal to the surface integral of electric current density flux across the nanopore unit normal surfaces between times t1 and t2.  
➢ DNA Sequencing
➢ Prepare ✓ Streamlined library prep in as little as 10 minutes
✓ PCR-free library prep using 400 ng DNA

➢ Sequence
✓ Real-time sequencing on MinION, GridION or PromethION
➢ Analyses

✓ Detect DNA modifications using open-source tools.  
2) Mutually compare everyone patient drug target whole gene precision sequence for total 600-recruited double-blind NSCLC patients.  
3) Calculate each drug target gene SNP in all 600-recruited double-blind NSCLC patients.  
4) Correlate everyone patient drug target gene SNP to everyone patient drug efficacy.  
5) Correlate everyone patient drug target gene SNP to everyone patient drug safety.  
6) Mutually compare the usual approach group SNPs (300 double blind random group separated NSCLC patients)

If any participating patients have serious side effects, they will be stopped the research.  
If any participating patients have no therapeutic effects, they will be stopped the research. 21 CFR 312.2(b)(5) exempts from the IND requirements my clinical investigation that involves use of a placebo.

Minimal risk means that the probability and magnitude of harm or discomfort anticipated in the research are not greater in and of themselves than those ordinarily encountered in daily life or during the performance of routine physical or psychological examinations or tests. The IRB00009424 must let all subjects sign a written consent form and will let the research NCT06062810 present no more than minimal risk of harm to subjects as well as will let the research NCT06062810 involve no procedures for outside the written consent document context.

21 cfrss56.111 (a) (1)

Risks to subjects are minimized: (i) By using procedures which are consistent with sound research design, and which do not unnecessarily expose subjects to risk, and (ii) whenever appropriate, by using procedures already being performed on the subjects for diagnostic or treatment purposes.

XALKORI - crizotinib capsule DAILYMED **Label** If any participating patients have serious side effects, they will be stopped the research. If any participating patients have no therapeutic effects, they will be stopped the research. 21 CFR 312.2(b)(5) exempts from the IND requirements my clinical investigation that involves use of a placebo.  
My clinical investigation (**NCT06062810**) intends to explore the relationship between single nucleotide polymorphisms **(SNP)** and crizotinib response and toxicity in patients with non-small cell lung cancer.  
My investigation information is from exploratory studies and is research data from general gene expression analyses in biopsy tissue cancer cells of humans and from single-nucleotide polymorphism
(SNP) analysis of trial participants. So, my pharmacogenomic data submission to **an IND is NOT required**, (i.e.,
my information does not meet the criteria of 21 CFR § 312.23).  
My clinical study (**NCT06062810**) meets all of the requirements for exemption from the IND regulations and, therefore, **an IND is not required** to conduct my clinical investigation; i.e., my clinical investigation of oncology drug product (Crizotinib **Capsule**) that is lawfully marketed in the United States is exempt from the requirements of **this part** (i.e. 21 CFR Part 312): i.e., my clinical investigation is exempt from the requirements of 21 CFR §312.305 (c)(1) and 21 CFR §312.305 (c)(3). Although I am not a licensed physician, I still can be a qualified investigator for my IND EXEMPT SNP oncology drug clinical investigation.  
IND 168463 should be IND EXEMPT. In my APCR documents, Han Xu, M.D., Ph.D., FAPCR had been defined as **PI (Principal Investigator)** in clinical trials. According to **42 CFR Part 11**, in my document **ClinicalTrials.gov ID:**
NCT06062810, I (**Han Xu, M.D., Ph.D., FAPCR**) am defined as **Responsible Party (Sponsor-Investigator)**,
Study Principal Investigator [Principal Investigator (PI)], Study Director (Medical Director), and Study Chair
(IRB Chair) in my clinical trial. So, I must be the **sponsor-investigator (S-I)** of my clinical trial. And I (**Han Xu, M.D.,**
Ph.D. i.e., **Sponsor** i.e., **Sponsor-Investigator**) can both initiate and conduct, alone or with others, my clinical investigation. At the same time, I am a qualified investigator for my **IND EXEMPT SNP** oncology drug clinical trial.  
My clinical investigation (**NCT06062810**) is not intended to be reported to FDA as a well-controlled study in support of a new indication for use, nor intended to be used to support any other significant change in the **labeling** for my oncology drug (Crizotinib **Capsule**). My investigation does not involve a change in route of administration, dosage level, or patient population, or other factors that significantly increase the risks (or decreases the acceptability of risks) associated with use of the drug product. My IND 168463 should be IND EXEMPT. My investigation (**NCT06062810**) is conducted in compliance with the requirements of 21 CFR 312.7, i.e., the oncology drug (Crizotinib **Capsule**) may not be represented as safe or effective for the purposes for which it is under investigation, nor may it be commercially distributed or sold. So, my clinical investigation (**NCT06062810**) of oncology drug product (Crizotinib **Capsule**) that is lawfully marketed in the United States is exempt from the requirements of **this part** (i.e., 21 CFR Part 312):
i.e., my clinical investigation is exempt from the requirements of **21 CFR §312.23 (a)(1)(iii)**.  
Our IRB's review of the investigator's qualifications and the sponsor's qualifications, including any institutional requirements for sponsor-investigator studies, will surely abide by **21 CFR 312.2(b)(1)**.
