used Low Dose Combined Chemotherapy on Abiraterone Tablet plus Prednisone Tablet plus Relugolix 
Tablet, based on precisely sequencing drug targets' genes, it will try to do following:  
 
➢ Correlate CYP17 Gene SNP to Therapeutic Effects of Using Abiraterone to Treat Prostate Cancer (PC), 
via Testing Peripheral Blood DNA.  
➢ Correlate SULT2A1 Gene SNP to Side Effects of Using Abiraterone to Prostate Cancer (PC), via Testing

The detailed methods: 
 
1) Detect each drug target whole gene precision sequence of everyone patient for all 600-recruited 
double-blind prostate cancer 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.  
✓ PCR option for very low input amounts

➢ 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 prostate cancer 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 PC patients) 
with the study approach group SNPs (300 double blind random group separated PC patients). 
7) Confirm the relationship between drug target gene SNPs and drug efficacy.

21 CFR§56.102 (i)  
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 
NCT03348670 present no more than minimal risk of harm to subjects as well as will let the research 
NCT03348670 involve no procedures for outside the written consent document context.  
 
21 CFR§56.111 (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.  
 
The study patients of NSCLC follow up the standard of care treatment with drug therapy in the

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 (NCT03348670) intends to explore the relationship between single nucleotide 
polymorphisms (SNP) and abiraterone response and toxicity in patients with prostate cancer. My 
investigation information is from exploratory studies and is research data from general gene expression 
analyses in white blood 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 (NCT03348670) 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 (Abiraterone Tablet) 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 168800 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: 
NCT03348670, 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 (NCT03348670) 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 (Abiraterone Tablet). 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 168800 should be IND EXEMPT. My investigation (NCT03348670) is conducted in compliance with 
the requirements of 21 CFR 312.7, i.e., the oncology drug (Abiraterone Tablet) 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 (NCT03348670) of oncology drug product (Abiraterone Tablet) 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).

I (Han Xu, M.D., Ph.D. i.e., Sponsor i.e., Sponsor-Investigator) as IRB Chair of our IRB (IRB00009424) will 
only organize the IRB meeting but give up my voting power in the determination of IRB, when I conduct my 
clinical investigation (NCT03348670).
