Brief summary:
This phase 1b trial studies the biologic effect of 9cUAB30 on early stage breast cancer. 9cUAB30 is a retinoid X receptor (RXR)-selective retinoid that acts in a tissue selective manner with the goal of minimizing side effects, a necessary feature of agents under development for cancer prevention.

Detailed description:
PRIMARY OBJECTIVE:

I. Compare molecular analysis of pre- and post-treatment tissue samples of breast cancers of patients treated with 14-28 days of oral retinoid X receptor (RXR)-selective retinoid 9cUAB30 (9 cUAB30) will demonstrate significantly reduced proliferation.

SECONDARY OBJECTIVES:

I. Determine if 14-28 days of oral RXR-selective 9c-UAB30 treatment increases apoptotic index, as measured by cleaved caspase 3 assay.

II. Examine the differences in gene expression from baseline to post-exposure breast cancer samples using a custom gene panel from Nanostring Technologies.

III. To examine if the maximum concentration (Cmax) and safety of 9cUAB30 in the first 5 participants is affected by reducing the number of capsules at the 240 mg dose level.

IV. To examine the Cmax of all participants at baseline and on the day of surgery.

V. Determine if treatment with 2-4 weeks of 9cUAB30 prior to surgery will increase gene expression of type I immune cells in the tumor immune environment of all participants except the first 5.

VI. Assess the overall safety of 9cUAB30 in comparison with known retinoid toxicity.

EXPLORATORY OBJECTIVE:

I. Determine if treatment with 2-4 weeks of 9cUAB30 prior to surgery will increase activated type I dendritic cells in peripheral blood.

OUTLINE:

Patients receive retinoid 9cUAB30 orally (PO) once daily (QD) for 14 to 28 days. Patients then undergo tumor resection surgery. Patients undergo blood and urine sample collection throughout the study.

After completion of study treatment, patients are followed up at 7 days and 4-5 weeks.

OBJECTIVES 
 
The overall goal is to determine if 9cUAB30 can produce a potentially beneficial biologic effect on human 
breast cancer at a non-toxic dose.  We hypothesize that comparative molecular analysis of pre- and post-
treatment tissue samples of breast cancers of patients treated with 14-28 days of oral RXR-selective 
9cUAB30 will demonstrate significantly reduced proliferation, increased apoptosis and changes consistent 
with ligand-RXR binding, as reflected in downstream markers, evaluated at the mRNA level by Nanostring, 
with selective confirmation at the protein level by IHC. 
 
1.1   
Primary Objective 
 
We hypothesize that comparative molecular analysis of pre- and post-treatment tissue samples of breast 
cancers of participants treated with 14-28 days of oral RXR-selective 9cUAB30 will demonstrate 
significantly reduced proliferation.   
 
1.2 
Secondary Objectives  
 
1.2.1  Determine if 14-28 days of oral RXR-selective 9cUAB30 treatment increases apoptotic index, as 
measured by cleaved caspase 3 assay.  
 
1.2.2  Examine the differences in gene expression from baseline to post-exposure breast cancer samples 
using a custom gene panel from Nanostring Technologies. Examined genes will be selected as described 
below and will include up to 48 genes. Prospective biomarkers on the panel will include but are not limited 
to (A) biomarkers associated with cell proliferation or apoptosis: PCNA, p21, p27, TUNEL assay, caspase 
3; (B) potential biomarkers of rexinoid activity reported in published studies: ABCA1, ABCG1, RARβ, 
SREBP-1c, cyclin D1, IGFBP6; (C) potential biomarkers of response to 9cUAB30 as defined in our 
preliminary studies: RET, MEN1, mTOR, AKT1, AKT2, 4EBP1, eIF4G1, S6K, IGFBP5, TGFβR1, 
PPARα, PPARγ (D) housekeeping genes for normalization: GAPDH, TUBB, PGK1, GUSB, and CLTC. 
Additionally, as possible, we will perform IHC for a subset of 5 of the most differentially regulated genes 
found on Nanostring to verify that gene expression data also results in protein differences. 
 
1.2.3 
To examine if the Cmax and safety of 9cUAB30 in the first 5 participants is affected by reducing 
the number of capsules at the 240mg dose level. That is using 3 capsules of 80mg each instead of 12 capsules 
of 20mg each. 
 
1.2.4  To examine the Cmax of all participants at baseline and on the day of surgery 
 
 
1.2.6 
Determine if treatment with 2-4 weeks of 9cUAB30 prior to surgery will increase gene expression 
of type I immune cells in the tumor immune environment of all participants except the first 5 
 
1.2.7    Assess the overall safety of 9cUAB30 in comparison with known retinoid toxicity.  
 
1.3  
Exploratory Objective 
1.3.1 
Determine if treatment with 2-4 weeks of 9cUAB30 prior to surgery will increase activated type I 
dendritic cells in peripheral blood.

BACKGROUND 
 
2.1 
Study Disease 
 
In 2019, an estimated 268,600 new cases of invasive breast cancer and 48,100 new cases of DCIS were 
diagnosed in women in the United States and approximately 41,760 women were expected to die from 
breast cancer.1 Prevention of breast cancer not only is key to reducing breast cancer mortality but also  to 
improving quality of life by reducing the number of patients who have to undergo surgery, chemotherapy 
and radiation therapy to treat their cancers.  
 
Women at increased risk for breast cancer are candidates for hormonal prevention strategies. Two selective 
estrogen modulators (SERMs), Tamoxifen or raloxifene, are highly effective ( 50%) in reducing risk of 
ER+ breast cancers.  Aromatase inhibitors (AIs) prevent the recurrence of invasive ER+ cancers as well as 
or better than SERMs. Currently, Exemestane, an AI, is included in management guidelines as an alternative 
to tamoxifen or raloxifene to reduce risk of invasive ER+ breast cancer in postmenopausal women at 
increased risk for breast cancer. However, because of the real and perceived risks of chemoprevention, 
patient uptake of current chemoprevention strategies remains low.2 3Studies show that only 12% of women 
at high risk for breast cancer opt for Tamoxifen as a preventive agent. The main reason women are declining 
Tamoxifen is due to concerns about toxicity.4 Moreover, a significant population of high-risk women will 
develop cancers that are not prevented by currently approved prevention strategies. For example, women 
with mutant BRCA-1 usually develop tumors that are ER-negative/PR-negative/Her2neu negative. 
Evidence is sparse that these patients will respond to traditional hormonal prevention.5 There is a need for 
an oral preventive agent with an attractive side effect profile that will prevent both ER-positive and more 
aggressive ER-negative breast cancers. 
 
2.2 
Study Agent 
 
Retinoids, which target the retinoic acid receptors (RARs), and rexinoids, which target the retinoid X 
receptors (RXRs), represent two classes of potential drugs with potent capacity to prevent breast cancers 
and have been studied extensively. 9-cis-Retinoic acid (9cRA) is a potent agonist for RXRs,6-10which 
activates RXR homodimer-mediated transcription or heterodimer-mediated transcription with other 
receptors of the steroid/thyroid superfamily (e.g. RARs, VDR, PPAR, TR and orphan receptors). These two 
pathways lead to activation of gene transcription that is responsible for the induction of differentiation and 
apoptosis. Thus, RXRs are the master regulators of gene expression of the RAR- and RXR-signaling 
pathways, and both pathways can be controlled by 9cRA.8-11 9-cis-retinoic acid has been shown to be 
effective in preventing mammary gland tumors in N-methyl-N-nitrosurea (MNU) animal models, 
unfortunately, the effective dose is near its maximally tolerated dose.12  
 
Targretin and other RXR-selective ligands, or rexinoids, have been developed in an effort to identify a 
rexinoid that will be safe for chronic human use. Targretin is the best studied rexinoid and FDA approved 
to treat cutaneous T-cell lymphoma. Targretin shares little structural similarity to 9cRA, and human clinical 
trials revealed it was better tolerated than 9cRA. Targretin did not produce many of the classic retinoic acid 
associated toxicities of 9cRA (bone fractures; skin lesions and redness; elevated serum calcium) but does 
produce dose-limiting hyperlipidemia (both elevated cholesterol and triglycerides) and hypothyroidism.13,14 
The lower toxicity of Targretin relative to 9cRA did not reduce potency of this rexinoid in cancer 
prevention. Several studies demonstrated Targretin was as effective as 9cRA in reducing the number and 
tumor burden of ER+ mammary cancers.12,15 Other groups established that the effects of combining 
Targretin or 9cRA with a SERM were additive and the combination regimen significantly decreased tumor

2.2.3 Preclinical toxicity studies 
 
In a series of preclinical studies conducted via the NCI DCP RAPID program, 9cUAB30 was found to have 
no lipid toxicity in two species (rat and dog), 28 and it had fewer side effects than Targretin. 9cUAB30 
displayed favorable pharmacology and was not mutagenic.29,30 
 
2.2.4 Human Studies 
 
After IND approval in 2009 (IND#101,604), DCP funded the first Phase 1 trial. Between November 2008 
and May 2009, 14 healthy volunteers at the University of Wisconsin (UW) were treated with single doses 
of 9cUAB30, 4 subjects at 5mg, 6 subjects at 10 mg, and 4 subjects at 20 mg.31 Subjects were 50% male 
and 50% female and all were white, non-Hispanic. Subjects were enrolled in groups of 4 sequentially into 
the progressively higher dose groups; a single dose of 5, 10, or 20 mg of 9cUAB30 was given orally in the 
morning on an empty stomach.  No subjects at dose level 5 mg or 20 mg experienced ≥grade 2 toxicity. 
There were few observed ≤ grade 1 laboratory abnormalities, including 2 subjects with grade 1 
hypertriglyceridemia After Tmax (2-3 hours after dose), 9cUAB30 levels declined steadily. Plasma half-
life increased in a dose dependent manner, averaging 2.79 hours in the 5-mg group, 5.76 hours in the 10-
mg group, and 7.21 hours for the 20-mg group. In regression analysis, AUC increased linearly across the 
examined dose range of 5 to 20 mg; a linear relationship between AUC and dose was found to be significant 
(β=38.7, p < 0.001). Cmax, increased with dose, but not in a linear fashion; it was found to be proportional 
to the log of dose (β= 4.43, p < 0.001). The average plasma clearance ranged from 25 to 39 L/h compared 
to the average renal clearance which ranged from 0.018 to 0.103 L/h.   
 
 
We initiated a double-blind, placebo-controlled single and multi-dose study of 9cUAB30 in healthy 
volunteers at 3 participating organizations (UW, UAB, and University of Iowa). Over the course of two 
different protocols (UWI09-8-02, UWI10-16-01R), 44 participants were enrolled into the study in cohorts 
of 10 (8 9cUAB30:2 placebo). The starting dose level was 20 mg followed by dose cohorts at 40 mg, 80 
mg, 160 mg, and 240mg daily. Subjects received a single, initial dose of study drug (fasting) on day 1 with 
full pharmacokinetic (PK) and safety monitoring for 24 hours and continued observation off study drug 
until returning the morning of day 8 for PK sampling and initiation of continuous daily dosing (day 8 -35) 
when they would return for full PK monitoring for 24 hours after their last dose. Summary PK parameters 
are presented in Table 1; we observed a linear to near linear increase in peak concentrations and AUC from 
20 to 160 mg per day of 9cUAB30. There was no further increase in 9cUAB30 concentrations (Cmax or 
AUC) from 160 to 240 mg dosing, in fact there was even some evidence to suggest a possible decline in 
drug levels raising the possibility of absorption issues/interference due to the large number of gelatin 
capsules at 240 mg (12 capsules). Comparison of baseline and day 36 pharmacokinetics parameters did not 
suggest drug accumulation or altered metabolism (whether an increase or decrease in absorption or 
clearance) with repeated dosing.

Subjects were followed for 30 days after their last study dose and escalation to the next dose cohort occurred 
after all 10 subjects at a dose level had completed the course with ≤1 subject experiencing unacceptable, 
attributable toxicity. Characteristics of the 44 subjects were; mean age - 40.9 (SD 13.5); ECOG performance 
status – all zero; 27 male; 17 female; 39 subjects - white, 5 - African American; all identified as not Hispanic 
or Latino. Early evaluation of observed toxicity did not reveal any consistency or pattern of toxicity 
normally seen with rexinoids. Reports of nausea or headache were rare and did not persist despite continued 
administration of study drug. Skin changes and fatigue were rarely reported. Serum lipid abnormalities 
were noted but rarely consistently elevated from baseline.

2.3 
Rationale 
 
The goal of this Phase 1b window trial is to ensure that 9cUAB30 produces a biological effect in humans 
and to identify candidate RXR signaling pathways that may play a role for cancer prevention. We believe 
the low toxicity of the rexinoid 9cUAB30 will be well-received for prevention of breast cancers in the high 
risk population, and potentially even better received for women who have had cancer and wish to prevent 
the occurrence of a second tumor. The results of this study will help to determine the suitability of continued 
study with 9cUAB30 as a chemoprevention drug in trials proposed by the NCI DCP in the Clinical 
Development Plan of 9cUAB30. 
 
Treatment with 9cUAB30 in animal models reduced proliferation and number of tumors in both ER+ and 
ER- breast cancer animal models, suggesting a chemopreventive effect of the drug. To evaluate the anti-
proliferative effect in humans, we chose the pre-surgical window trial design. The model of short-term 
administration of a drug between the window of diagnosis to operative intervention, allows for evaluation 
of biomarker response from baseline (core biopsy) to post-treatment (surgery). Several pre-surgical trials 


DCP Protocol #:  UWI2015-05-01 
Protocol Version: 20 
01/28/2022 
DCP Protocol Template Version 8.4

10/29/2015 
have shown the ability of SERMs to reduce proliferation as measured by Ki67 after short-term 
administration. In these trials administration of tamoxifen or other SERM results in decrease of Ki67 by 
approximately 40% when surgical resection samples are compared with pretreatment core biopsy samples. 
32-35 We expect that 9cUAB30 will reduce proliferation and increase apoptosis.  
 
Because breast cancer prevention/therapy preclinical mouse model data with Targretin, 9cRA and 
9cUAB30 suggest a linear relationship between increasing dose/concentration and anti-cancer effects, it is 
important to explore the highest 9cUAB30 dose that pharmacodynamics suggest.  The new formulation of 
9cUAB30 will significantly lower the gelatin: active ingredient ratio (12 capsules vs 3 capsules) thus raising 
the potential of higher tissue exposure at 240 mg as compared to 160 mg.  Therefore, we plan to “pilot” the 
240 mg dose in initial participants with planned assessment of C2hr (Tmax usually at 2 hours) at 2 hours 
post initial dose. If real time assessment of 9cUAB30 concentrations observe a significant increase over 
957 ng/ml levels we will continue at 240 mg/day. If initial concentrations are not appreciably >957 ng/ml 
with 240 mg/day, participants will be treated at 160 mg/day.  
 
Further, we plan to evaluate the potential effect of 9cUAB30 on various breast cancer pathways, shedding 
light into the mechanism of action to help design future trials.  
 
Increasing evidence suggests that tobacco and alcohol use are risk factors in the development of 
intraepithelial neoplasia and cancer. In addition, tobacco and alcohol use may adversely affect agent 
intervention, for example by altering the safety profile or metabolism of a drug. Standardized assessments 
of tobacco and alcohol use during clinical trials will aid in understanding the potential relationship between 
the use of these products and clinical endpoints or cancer prevention biomarkers. Therefore, NCI, DCP is 
including assessment of tobacco and alcohol use at baseline and at surgery, to determine the potential impact 
of tobacco and alcohol use on 1) treatment toxicity and symptom burden, and 2) the efficacy of treatment 
intervention. 
 
The rexinoic acid receptor bexarotene decreases Th2 tumor immune environment and increases 
CD8+ T-cells in breast tumors of TgMMTV-neu transgenic mouse mammary tumor model. 
 
The rexinoic acid receptor (RXR) agonists bexarotene and 9cUAB30 have been shown to prevent breast 
cancer through inhibiting proliferation.,43,44,45 RXR has also been shown to have immune roles, although 
the effects vary depending on the immune environment, including preventing T-cell apoptosis and 
inhibiting the viral response to infection.46 47,48 The breast cancer tumor immune microenvironment can 
determine both whether a tumor will be responsive to therapy and predict a patient’s risk of relapse.49,50  A 
type I immune environment is essential both to recruit CD8+ T-cells to the tumor and to ensure that these 
CD8+ T-cells are active to destroy the tumor.51,52 On the other hand, Th2 regulatory T-cells induce a type II 
immune response which suppresses CD8+ T-cell activity.53 The majority of breast tumors develop an 
immunosuppressive immune environment which begins to develop in DCIS and increases as the tumor 
progresses to IBC.54 This immunosuppressive environment prevents the level of anti-tumor immune 
infiltration in the majority of breast tumors that is necessary for improved immune tumor destruction and 
better prognosis.55  
 
We have demonstrated that bexarotene can decrease both hyperplasia and invasive breast cancer while 
increasing CD8+ T-cells in the tumor in TgMMTV-neu mice. Furthermore, bexarotene was able to enhance 
the efficacy of a multi-antigen vaccine to prevent breast cancer in these mice suggesting an anti-tumor 
immune role for bexarotene.  When mice were vaccinated with the HER2-IGFBP2-IGF1R vaccine and 
concurrent bexarotene, the percent of mice that did not develop tumors increased from 65% to 87% (HR 
18.1 95% CI 6.4 to 63.2, p<0.0001).  Bexarotene alone only inhibited tumor development in 15% of the 
mice that was not significantly more than in the adjuvant controls (p=0.307).56 Similar to human breast

cancer, TgMMTV-neu mice develop a type II tumor immune environment.7 When treating TgMMTV-neu 
mice that had existing 100 mm3 tumors with bexarotene, we found the tumor immune environment became 
more type I with increased CD8+ T-cells in the tumor and decreasing GATA3+ cells (a marker of Th2 T-
cells) in the tumor (Fig. 3).  Because of bexarotene’s role in modulating the immune environment, we 
wanted to determine if the rexinoic acid receptor in human immune cells.   
 
In evaluating RXR expression in human peripheral blood mononuclear cells (PBMC), we found that RXR 
had the highest expression in antigen presenting cells (APC).  RXR is expressed in almost 30% of APC, 
24.9±13% of macrophages, 38.6±14% of plasmacytic dendritic cells (pDC), 33.1±16% of monocytic 
dendritic cells (mDC) (Fig. 4).  Further, when PBMC were treated with increasing doses of bexarotene for 
48 hours, there was increased co-stimulatory CD40 expression on mDC (indicating mDC activation, p=0.03 
between 0 and 20 uM bexarotene, Fig 5A) and pDC (indicating pDC activation, p=0.05 between 0 and 20 
uM bexarotene, Fig 5B).  There was also increased type I cytokine release including IL-1β (p=0.04 between 
0 and 20 uM bexarotene Fig 6A) and TNFα (p=0.03 between 0 and 20 uM bexarotene Fig 6B) but not type 
II cytokine release of IL-10 (p=0.99) and IL-4 (p=0.97) (Fig 6C and D).  Infiltration of activated dendritic 
cells has been associated with improved prognosis in multiple solid tumors.58,59  These data suggest that 
bexarotene can activate and bias DCs to develop into type I DCs and therefore may have an immune 
component of its anti-tumor activity. 
 
Activation of monocytic dendritic cells is conserved between RXR agonists bexarotene and 9cUAB30.  
While bexarotene may have both an anti-proliferative and immune anti-tumor role, it has been associated 
with significant toxicities including pancreatitis, hypertriglyceridemia, headache, and thyroid 
abnormalities.60 A second novel retinoid 9cUAB30 is much better tolerated, with only grade 1 and 2 
toxicities in an initial 14-person healthy volunteer dose escalation study.31  9cUAB30 has been shown to be 
effective with tamoxifen in hormone-induced mammary cancers in rats reducing tumor growth by 57%.61 
From preliminary experiments comparing the activation of dendritic cells by 9cUAB30 and bexarotene in 
parallel, 9cUAB30 can also increase CD40 expression on monocytic dendritic cells (p=0.05 at 20 uM as 
compared to 0 uM 9cUAB30, Fig 7D) and plasmacytic dendritic cells (p=0.02 at 20 uM as compared to 0 
uM 9Cuab30, fig 7E)  suggesting that this activity is conserved across RXR agonists.  We therefore aim to 
evaluate whether increasing doses of 9cUAB30 can activate type 1 dendritic cells and enhance the type I 
immune environment in women with early stage breast cancer.  We hypothesize that the activation of type 
I dendritic cells by the RXR agonist 9cUAB30 can contribute to its anti-cancer activity.

SUMMARY OF STUDY PLAN 
 
Eligible participants will be ≥18 years of age and newly diagnosed pre- or post-menopausal patients with 
core biopsy proven invasive breast cancer between 0.5 cm and 5 cm in size or DCIS that is ≥ 1.0 cm in size 
and is either Grade 3 ER+ DCIS or ER- DCIS of any grade 
 
Patients agreeing to participate will take 9cUAB30 240 mg (160 mg contingent on interim analysis) by 
mouth daily for 14 – 28 days until the time of surgery. Tissue from the core biopsy will be used for the pre-
treatment biomarker analysis. The tissue obtained from the surgical excision will be used for post-treatment 
biomarker analysis. We plan to enroll ER+ participants and ER- participants for a total of up to 41 
participants undergoing intervention. We expect the study to be complete within 18-24 months. Beginning 
in November 2021, participants will be limited only to estrogen receptor negative status. 
 
At baseline all participants will have a complete medical history, physical examination and review of 
concomitant medications. Participants will undergo laboratory testing to determine eligibility within 30 
days prior to day 1 of the study. Baseline laboratory tests will include WBC, differential, hemoglobin,

hematocrit, platelets, INR, PTT, AST, ALT, total bilirubin, alkaline phosphatase, BUN, creatinine, calcium, 
glucose, albumin, electrolytes (Na, K, Co2, Cl), HDL, LDL, total cholesterol, triglycerides, thyroid 
stimulating hormone, FT3, and FT4 (may omit any if collected as part of initial cancer workup documented 
in the medical record within 30 days of study Day 1). A plasma and urine sample for pharmacokinetic (PK) 
analysis will also be obtained. An additional 30 ml blood sample will be obtained to evaluate and measure 
the immune response of 9cUAB30 in participants 6-25.  
 
For the first 5 participants, two extra plasma PK samples will be collected after administering the first dose 
of the study agent at 5 minutes and 2 hours post the drug administration to evaluate the Cmax. After the 
first 5 participants complete study participation, their PK samples will be evaluated to determine the Cmax 
and adverse events will be evaluated to determine safety of the 240mg dose. Based on this evaluation, it 
will be determined to continue study dose at 240mg or to reduce to 160mg (refer to section 13.9). 
 
For all study participants, 1 H&E stained slide, 5 unstained slides of 5µm thickness and 5 unstained slides 
of 10µm thickness will be requested from the diagnostic core biopsy formalin fixed paraffin embedded 
(FFPE) tissue block containing tumor using the existing diagnostic core biopsy material already collected. 
 
As part of the assessment of participant evaluability, a pathologist will examine the deepest level cut from 
blocks of the core biopsy and surgical resection specimens containing tumor. If the estimated residual tumor 
in the block is considered sufficient to enable cutting of at least 5 unstained slides at 5µm thickness, needed 
to support the future performance of Ki-67 and caspase 3 assays, the participant can be considered 
evaluable. 
 
Once a surgery date is scheduled, participants meeting eligibility requirements will begin oral 9cUAB30 
for daily treatment for at least 14 (but not longer than 28 days) days at the 240 mg/day dose level (160 mg 
contingent on interim analysis) prior to surgery. The day the participant begins taking 9cUAB30 is 
considered Day 1 of the study. Each participant will be provided with a blood pressure (BP) monitor to 
track the BP values at home. During the visit, participants will be instructed on how to use the monitor. The 
instructions are noted on the BP diary (Appendix C) for reference at home. Participants will be asked to 
measure and document the blood pressure values in the BP diary on Day 7, Day 8 (approximately 24 hours 
later) and the day prior to surgery. All BP readings should be taken in the morning. They will be instructed 
to notify the study team if the value of the reading is Systolic ≥160 and Diastolic ≥100. The study 
coordinator will contact the participant on Day 8 by telephone to assess adverse events and other symptoms, 
review medications and review the BP readings. Study team will also contact participants on the day before 
surgery to remind them to take last dose of medication, bring the pill diary and blood pressure monitors and 
bring all the pill bottles given to them. Participants will be encouraged to contact the investigator or study 
coordinator with any new symptoms or concerns at any time during the trial.  
 
Surgery must occur between Days 15 and 29 of the study. On the day of surgery or the day before surgery 
laboratory tests will be obtained and include WBC, differential, hemoglobin, hematocrit, platelets, INR, 
PTT, AST, ALT, total bilirubin, alkaline phosphatase, BUN, creatinine, calcium, glucose, albumin, 
electrolytes (Na, K, Co2, Cl), HDL, LDL, total cholesterol, triglycerides, thyroid stimulating hormone, FT3, 
FT4, as well as a plasma and urine sample for PK. The history and physical examination will be obtained 
and/or updated within 24 hours of the procedure. An additional 30 ml blood sample will be obtained during 
this visit to evaluate and measure the immune response of 9cUAB30 by comparing it to the sample obtained 
at baseline for participants 6-25.   
 
At the time of surgery, tissue samples will be obtained of remnant tumor and processed as is the usual 
standard at each institution. One H&E stained slide, 5 unstained slides of 5µm thickness and 5 unstained

slides of 10µm thickness will be requested from the formalin fixed paraffin embedded (FFPE) tissue 
blocks containing tumor as described in section 10.2.1 
 
The plasma and urine samples for PK will be sent to University of Wisconsin - CP lab for evaluation. The 
immunogenicity samples will be sent to University of Washington – Tumor Vaccine Group. All other 
baseline and pre-surgical laboratory studies will be performed at each participating institution.  
 
All participants will receive $30 for completing the screening visit, $70 for completing the surgery visit and 
returning the blood pressure machine as compensation towards the extra efforts taken such as travel 
expenses, parking, time missed from work or other expenses associated with the study visits. The first 5 
participants will be given additional $50 for the additional time required for the study visit. 
 
The study participants will be matched with historical nonrandomized controls from each site based on sex 
(female), pathologic stage, receptor status, grade, and menopausal status from each site. These samples will 
be obtained from blocks no more than 5 years old. The pre-surgical and post-surgical tissue samples (from 
the participants and matched controls) will be batched and analyzed concurrently utilizing 
immunohistochemistry and Nanostring to measure any effects of 9cUAB30 on tumor cell proliferation 
(Ki67) and activation of RXR downstream pathways (gene expression). Slides will be analyzed via 
immunohistochemistry at Wisconsin and via Nanostring at UAB per existing protocols. 
 
Seven days after surgery and 4-5 weeks after surgery a follow-up phone call will be performed for safety 
assessment.

diagnosis. The use of non-systemic estrogen (such as vaginal estrogen use) is allowed. 
10. The effects of 9cUAB30 on the developing human fetus are unknown. Since retinoids are known to be 
teratogenic, to avoid any complications due to unintentional pregnancies only postmenopausal women 
and some premenopausal women (as outlined below) will be eligible. Should a woman become 
pregnant or suspect she is pregnant while participating in this study, she should inform her study 
physician immediately. 
• 
Women will be considered postmenopausal if one of the following is met: 
i. Prior bilateral oophorectomy 
ii. 60 years of age or older 
iii. Age less than 60 years; amenorrheic for 12 or more months; and follicle-stimulating hormone 
(FSH) in the postmenopausal range or had prior hysterectomy. 
• 
Premenopausal women without childbearing potential are eligible to participate if one of the 
following criteria is met:

the immune system.  
8. Participant with a history of a second cancer diagnosis or reoccurrence <2 years from study entry with 
the exception of a history of squamous or basal cell carcinoma of the skin <2 years from study entry 
will not be excluded from this study. This is to eliminate the residual effects of any previous treatments 
for those cancers.  
9. Participant with history of ipsilateral breast radiation.  
10. Participant’s core biopsy slides suggest that later re-sectioning will not contain sufficient tumor to allow 
for an adequate evaluation of Ki67 and caspase 3 assays, at a minimum. 
 
***To assess hypertension during eligibility verification, see below instructions: 
For grade 1, grade 2, and non-persistent grade 3 hypertension, repeat blood pressure reading after 5 minutes.   
If the average reading of the two measurements is grade 3 (systolic BP 160 mm Hg or diastolic BP 100 
mm Hg) the patient is not eligible. If the average reading of the two measurements is less than or equal to 
grade 2, then the participant is eligible.  If the average of the 2 readings is grade 1 or grade 2 hypertension, 
document the appropriate level hypertension on the baseline symptom form.  
 
4.3 
Inclusion of Women and Minorities 
 
Women of all races and ethnic groups are eligible for this trial.  
 
4.4 
Recruitment and Retention Plan 
 
Potential participants will be screened and recruited from the University of Alabama at Birmingham, 
University of Wisconsin, University of Minnesota, University of Iowa and Northwestern University. Breast 
cancer surgeon investigators at each site will be instrumental in achieving accrual targets. The duration of 
the accrual is expected to take 18- 24 months. Beginning in November of 2021, study sites will be limited 
to University of Alabama at Birmingham, University of Wisconsin, and Northwestern University. 
 
Each site will review the surgeon’s clinic patient list to identify potential participants. Through review of 
the medical record, the study team will determine if a patient is eligible and contact them for interest in the 
study. Review of medical records prior to consenting to the research study is very minimum risk of harm 
to the potential study participants and involves no study related procedures for which written consent is 
normally required outside of the research context.  
 
 
The potential participant may be initially approached by their physician and the study coordinator will then 
speak with them more in depth about the study. 
 
We plan to have staggered enrollment for the study. We will enroll 5 participants at the 240mg dose level

and after analysis of the PK data collected from the first 5 participants, it will be determined whether to 
continue with 240mg dose level or to modify the dose to 160mg for rest of the study. If the study continues 
at 240mg dose level, the remaining 31 participants will be accrued. If the dose is determined to need to be 
reduced to 160mg, 36 participants will be accrued at 160mg. We expect a participant dropout rate of less 
than 5%.  
 
 
5. 
AGENT ADMINISTRATION 
 
Intervention will be administered on an outpatient basis. Reported AEs and potential risks are described in 
Section 6.2.  
 
5.1 
Dose Regimen and Dose Groups 
 
The study drug 9cUAB30 240 mg (3 capsules of 80 mg) or *160 mg (2 capsules of 80 mg) will be taken

PHARMACEUTICAL INFORMATION 
 
6.1 
9cUAB30 (IND 101,064, NCI, DCP)   
 
This Phase Ib clinical study investigating the biologic effect of a novel retinoid 9- cis-UAB30 (9cUAB30) 
will be conducted under an IND sponsored by NCI, DCP. 9cUAB30 [8- (3’,4’-dihydro-1-(2’H)-naphthalen-
1’-ylidene)-3,7-dimethyl-2,4,6-octatrienoic acid], has been synthesized at the University of Alabama (D. 
Muccio) and is undergoing development through the NCI, DCP RAPID program. This new RXR-selective 
retinoid is a conformationally- constrained analogue of 9-cis-retinoic acid (9-cis-RA) (Muccio et al. 1998).

Evidence continues to accumulate from in vitro and in vivo studies, as well as from clinical trials, that 
retinoids have therapeutic effects in several neoplastic diseases. Several RXR agonists (rexinoids) have 
undergone clinical evaluation as potential chemopreventive compounds. 9cUAB30 is a yellow powder 
which will be formulated into capsules as subsequently described. Active capsules are size 1, Swedish 
orange, hard-gelatin capsules containing 80 mg 9cUAB30 plus pregelatinized starch, colloidal silicon 
dioxide, crospovidone and magnesium stearate. All capsules are manufactured under contract to NCI, DCP, 
and are packaged in 60 cc white HDPE bottles, 30 capsules per bottle, with 33/400 polypropylene caps. 
 
6.2 
Reported Adverse Events and Potential Risks 
 
Nonclinical PK evaluations show that 9cUAB30 is orally available in mice, rats, and dogs. In mice, plasma 
9cUAB30 levels were similar after one and seven days of dosing, indicating no drug accumulation. 
Increases in the area under the drug concentration curve (AUC) were less than proportional to dose possibly 
due to an increased rate of clearance (Cl) and decreased half-life (t½) seen at the same time. In rats, drug 
levels increased with dose. In dogs, the time to maximal drug concentration (tmax) was 2–3.5 hours and t½ 
was 2.7–4 hours. In vitro metabolic studies suggest that human metabolism may be similar to canine 
metabolism and differ significantly from murine (rat) metabolism. In isolated human liver microsomes, the 
major cytochrome P 450 (CYP) isozymes responsible for 9cUAB30 metabolism were CYP2C8, CYP2C9 
and CYP2C19; at 10 M, 9cUAB30 also induced CYP2B6. A 9cUAB30 glucuronide conjugate can be 
formed by uridine diphosphate (UDP) glucuronosyltransferase 1A9 (UGT1A9).  
 
9cUAB30 has been evaluated in multiple nonclinical toxicity and safety pharmacology studies sponsored 
by NCI, DCP. In a 28-day oral toxicity study of 9cUAB30 in rats, target organs were the liver and 
hematologic system. Dose-dependent increases in liver weight as a percent of brain weight, vacuolation in 
liver tissue consistent with glycogen deposition, and increased serum aspartate aminotransferase (AST) and 
alkaline phosphatase (ALP) levels were observed. Hematologic changes included dose-dependent 
decreases in prothrombin time (PT), increases in fibrinogen, and, at the highest dose (100 mg/kg-bw-day), 
eosinopenia and neutrophilia. The no observed adverse effect level (NOAEL) was considered to be 
3 mg/kg-bw/day. In a 28-day oral toxicity study of 9cUAB30 in female dogs, no treatment-related toxicities 
were observed even at the highest dose (100 mg/kg-bw/day), which was considered the no observed adverse 
effect level (NOAEL). In safety pharmacology studies, no cardiac effects were seen in female dogs treated 
with single doses of 9cUAB30 up to 300 mg/kg-bw/day. Additionally, in a functional observational battery 
(FOB) study in rats, no effects on central nervous system (CNS) or behavior were seen with single doses 
of 9cUAB30 up to 100 mg/kg-bw/day. In genotoxicity studies, 9cUAB30 was negative in the in vivo mouse 
bone marrow micronucleus assay and the bacterial reverse mutation test (Ames). In the Chinese hamster 
ovary (CHO) cell assay, 9cUAB30 did not increase chromosome aberrations or polyploidy after three-hour 
exposure to low levels of 9cUAB30 in the absence of metabolic activation. However, longer duration (24 
hours) in the presence or absence of metabolic activation, or higher doses of 9cUAB30 with metabolic 
activation, increased chromosome aberrations and polyploidy. Because of variable outcomes and lack of a 
dose response in the CHO cell assay, 28-day in vivo mutagenicity and six-month oncogenicity studies were 
undertaken in transgenic mice. In the Big Blue lacI/cII transgenic mouse mutagenicity study, no dose-
related increases in mutation frequency were found in the liver, kidney, or spleen. In addition, 9cUAB30 
was not oncogenic in p53+/– transgenic mice, and there was no evidence of vitamin A-like toxicity. These 
results, combined with the negative oncogenicity and mutagenicity data, suggest an acceptable toxicity 
profile for 9cUAB30.  
 
9cUAB30 has been tested in normal volunteers in a phase 1, first-in-human, open-label, single ascending 
dose study (UWI06-8-03) and in a 28-day double-blind, placebo-controlled, randomized, multiple 
ascending dose (MAD) study (under two protocols UWI09-8-02, UWI10-16-01R). In the first study, single 
doses of 5, 10, and 20 mg 9cUAB30 were well tolerated and orally available, with a tmax of 2.2–3.1 hours.

Most adverse events (AEs) were grade 1 in severity; Grade 3 AE’s were rare and likely unrelated to study 
agent. There were no grade 4, or serious AEs (SAEs), and no dropouts. The most common treatment-
emergent AE (TEAE) was headache with the first dose and little to no occurrence thereafter raising the 
possibility of caffeine withdrawal due to fasting as a potential cause. Another common TEAE was grade 1 
(1 grade 3 event on day 1 prior to initial dose) hypertension which was more frequently observed with 
higher doses (see Table 3). Because of this observation, we more closely examined Blood Pressure results 
throughout the study (see figure 2).  Based on absolute BP readings there is no evidence of increased BP 
during the first 24 hours after their initial dose (data not shown) and no evidence of an increase from 
baseline through day 36 (figure 2). The increase in numbers of TEAE’s implies participants entered the 
study with borderline hypertension and resultant repeated measurements led to sporadic BP elevations 
meeting CTCAE requirements across participants and sustained elevations within participants where not  
seen.

Other common TEAEs were increased blood chloride, decreased hemoglobin (anemia), and 
hypercholesterolemia. Rare events such as rash, dry skin, sweating, burping after meals, shaking, 
temperature of body feeling warmer, were also observed. Interestingly, commonly associated 
retinoid/rexinoid toxicities were not observed with any frequency or significant grade (skin changes, 
headache, hyperlipidemia, leukopenia, etc.), supporting the hypothesis that the conformational changes to 
9cUAB30 structure as compared to 9cRA result in less toxicity.  Our data supports that 9cUAB30 daily 
dosing of ≤240 mg/day for up to 28 days continuously is safe.

Packaging and Labeling 
 
9cUAB30 capsules will be packaged by NCI, DCP. Each bottle will contain 30 capsules of 80mg 9cUAB30. 
Two-part labels will be placed on each bottle. One part stays on bottle, and one part goes into the participant 
chart or other designated research record as a source document. Sites will be responsible for recording the 
Participant ID (PID) number on the bottle once they are dispensed. The label remaining on the bottle will 
identify study specific information, such as Study title, DCP protocol number, dosing instructions, 
recommended storage conditions, the name and address of the distributor, and a caution statement 
indicating that the agent is limited by United States law to investigational use only and the agent should be 
kept out of reach of children. 
 
6.7 
Storage 
 
The agent should be stored at a temperature of between 2°and 8° C. Participants transporting study 
medication from clinic to home will be provided with a cold, but unfrozen, ice pack. Participants will be 
instructed to store study medication in the refrigerator.  
 
6.8 
Registration/Randomization 
 
CLO will be informed about the expected date and time of the scheduled screening visit as soon as it has 
been scheduled. 
 
PID will be assigned sequentially to all participants who sign consent form at the PO and will designate the 
recruitment site, the study and the participant. Once a participant has signed a consent form and has satisfied 
all eligibility criteria: 
 
• 
Fax (608-467-5900) or email (multisite_research@cancer.wisc.edu) the participant’s eligibility 
checklist signed by Investigator and copy of the signed consent form to CLO during normal business 
hours (M-F 8:00 am – 4:00 pm Central Time).  
• 
CLO will verify eligibility documents are complete and assign bottle numbers to dispense the study 
medication.  
• 
CLO will email a confirmation of accrual to the study coordinator at the participating institution 
including the bottle numbers to be assigned to the participant. If a confirmation is not received within 
two hours, the coordinator should contact the CLO to confirm that eligibility documents were received.  
• 
CLO will be responsible for tracking number of ER+ and ER- participants to ensure correct tracking of 
accrual. A notification of accrual will be sent to each PO after a participant has been assigned to 
treatment. 
• 
After receiving the confirmation from CLO, this information should be conveyed to the local site 
investigational pharmacist to process the study drug request.

Baseline Testing/Prestudy Evaluation 
 
7.2.1  Screening Visit (within 30 days of Day 1) 
 
Newly diagnosed early stage breast cancer patients will be screened as potential participants from the 
University of Alabama at Birmingham, University of Wisconsin, University of Minnesota, University of 
Iowa, and Northwestern University. A history and physical examination will be performed as part of 
standard of care by providers at each institution.   
 
The procedures to be performed to evaluate eligibility are:  
 
• 
Invasive breast cancer or DCIS confirmed on pathology report; eligible participants must have invasive 
breast cancer between 0.5 cm and 5.0 cm in size based on imaging or for DCIS-only lesions, the imaging 
abnormality corresponding to the cancer must be at least 1.0 cm in size (i.e. calcifications, distortion or 
mass on mammogram, or mass or nonmass enhancement on MRI).  
• 
Estrogen receptor status must be confirmed on pathology report. Estrogen receptor positivity defined 
as per 2010 ASCO-CAP Guidelines36 – with at least 1% positive tumor nuclei in the sample on testing 
in the presence of expected reactivity of internal (normal epithelial elements) and external controls.  
o Eligible participants must have invasive breast cancer that is ER+ or ER-,  
OR 
o Eligible participants must have DCIS that is ER+ and grade 3, or that is ER- and any grade. 
 
*Beginning in November 2021, participants will be limited to estrogen receptor negative status. 
 
• 
Her2neu status must be confirmed on pathology report for those with invasive cancer.37 Her2neu status 
is defined as positive and negative based on the 2013 ASCO-CAP guideline. As recommended by the 
guideline, Her2neu equivocal results must have a reflex or new test to determine Her2neu status.  
• 
Review of the participant's medical history. 
• 
Measurement of height and weight.  
• 
Evaluation of vital signs including temperature, pulse, blood pressure, and respiration rate. 
•

after 5 minutes.  
• 
If the average reading of the two measurements is grade 3 (systolic BP 160 mm Hg or diastolic 
BP 100 mm Hg) the patient is not eligible.  
• 
If the average reading of the two measurements is less than or equal to grade 2, then the 
participant is eligible.   
• 
If the average of the 2 readings is grade 1 or grade 2 hypertension, document the appropriate 
level hypertension on the baseline symptom form.  
• 
A physical examination. A gynecologic examination may be waived. The physical examination may 
be performed by any healthcare professional (i.e. physician, nurse practitioner, physician assistant) who 
is allowed by local policy to perform physical examinations.  
• 
Assessment of Performance Status, using the ECOG method (convert a Karnofsky score into an ECOG 
score using the scale in Appendix A).

• 
Patients agreeing to participate in the study will sign the informed consent document. 
 
After obtaining written informed consent, a participant is registered with CLO and assigned a unique PID 
number (see section 6.8) and eligibility evaluations may occur. Eligibility evaluations determine if the 
participant is a fit candidate for study participation. All eligibility evaluations (including labs) must be 
completed within 30 days of Day 1. The eligibility checklist is provided to each site to help determine if 
the participant is eligible for the trial.  
 
• 
Administer the baseline version of tobacco and alcohol assessment questionnaire – Appendix D 
• 
Perform the laboratory tests as outlined in section 7.1. Results from laboratory tests or physical 
examinations performed outside the context of the research study may be used to confirm eligibility, 
provided these procedures were conducted within 30 days of Day 1.  
• 
A fasting or non-fasting lipid panel may be obtained, if drawn within 30 days of Day 1. If non-fasting 
lipid levels are outside of the range for eligibility, a fasting lipid panel can be drawn. For the fasting 
lipid panel, participants should be fasting for at least 10 hours prior to this draw. 
• 
Collect urine and blood sample for baseline PK studies.  
• 
Collect 30 mL blood sample for immune studies for participants 6-25.  
 
If deemed eligible, follow the below mentioned procedures: 
 
For the first 5 participants:  
a. Since the participants will be fasting for the laboratory tests, they can have a meal after blood draw for 
laboratory tests while they wait to get their laboratory results.   
b. Once the lab results are obtained to determine eligibility, dispense the study agent in 3 bottles of 30 
capsules of 80mg each and administer the first dose of 240mg (3 capsules) at the clinic visit after 
minimum of 2 hours post their last meal.  The participant will be able to eat again after both PK blood 
draws are performed. This will be considered as Day 1. 
c. Document the date and time in the pill diary and provide the diary to participant with instructions on 
how to complete. 
d. First post-dose PK sample of 3mL blood will be collected within 5 minutes of drug administration.  
e. Second post-dose PK sample of 3 mL blood will be collected 2 hours from the time the drug was taken. 
Participants should not eat between the PK blood draws.  
f. The study dose has to be taken in the evening on empty stomach (2 hours after last eating and wait for 
1 hour before eating again), every day until the day before surgery.  
g. They will be provided with a BP monitor to measure BP at home. While they are in clinic, they will be 
instructed on how to use the monitor. The instructions are noted on the BP diary for reference at home 
(Appendix C).  Participants will be asked to measure and document the blood pressure values in the BP 
diary on Day 7, Day 8 (approximately 24 hours later) and day prior to surgery. All BP measurements 
should be taken in the morning. They will be instructed to notify the study team if the value of the 
reading is Systolic ≥160 or Diastolic ≥100 (grade 3). The study coordinator will contact the participants 
on Day 8 by telephone to assess adverse events and other symptoms, review medications and review 
the BP readings. 
 
For participants 6 onwards:  
a. Review guidelines for agent administration with the participant and provide the diary to participant 
with instructions on how to complete. 
b. Dispense study agent – 9cUAB30 based on the dose of the study determined by interim analysis. 
Participant will be given enough study drug for the duration of participation in the treatment phase of 
the study.

CRITERIA FOR EVALUATION AND ENDPOINT DEFINITION 
 
8.1 
Primary Endpoint

Our primary endpoint is that treatment with 9cUAB30 for 14-28 days will result in reduced proliferation as 
measured by Ki-67 expression in breast cancer tissue obtained at surgical resection compared with tissue 
obtained at diagnostic core biopsy/baseline.  
 
8.2 
Secondary Endpoints 
 
Our secondary endpoint is that treatment with 9cUAB30 for 14-28 days will result in increased apoptosis 
in breast cancer tissue obtained at surgical resection compared with tissue obtained at diagnostic core 
biopsy/baseline. Additionally, we plan to explore the effect of 9cUAB30 on a molecular level using 
Nanostring technology providing further insight into its mechanism of action. Examined genes will include 
up to 48 genes. Prospective biomarkers on the panel will include but are not limited to (A) biomarkers 
associated with cell proliferation or apoptosis: PCNA, p21, p27, TUNEL assay, caspase 3; (B) potential 
biomarkers of rexinoid activity reported in published studies: ABCA1, ABCG1, RARβ, SREBP-1c, cyclin 
D1, IGFBP6; (C) potential biomarkers of response to 9cUAB30 as defined in our preliminary studies: RET, 
MEN1, mTOR, AKT1, AKT2, 4EBP1, eIF4G1, S6K, IGFBP5, TGFβR1, PPARα, PPARγ (D) 
housekeeping genes for normalization: GAPDH, TUBB, PGK1, GUSB, and CLTC. Additionally, as 
possible, we will perform IHC for a subset of 5 of the most differentially regulated genes found on 
Nanostring to verify that gene expression data also results in protein differences. 
 
One of our secondary endpoint will be to examine if Cmax at Day 1 in the first 5 participants is increased 
from 957ng/ml by reducing the number of capsules for the 240mg dose level. Dose of each capsule has 
been changed from 20mg per capsule to 80 mg per capsule. We will examine if there is any difference in 
absorption of the study agent with this formulation. Additionally, we will examine adverse events in these 
participants for safety due to the change in formulation. 
 
In all of the participants we will examine the urine and plasma drug concentration levels of 9cUAB30 at 
baseline and on the day of surgery. 
 
Determine if treatment with 9cUAB30 modifies the tumor immune environment to a type I immune 
environment.  Tumor biopsy specimens collected prior to 9cUAB30 therapy and at the time of surgery will 
be tested as well as external comparator tumors before and after surgery untreated with 9cUAB30 and 
matched by site.  These tissues are being prepared for Nanostring to evaluate for expression of RXR genes.  
We propose to use these same RNA preparations to evaluate the Nanostring pan-cancer immune profiling 
panel on the tumor tissue.  We predict that there will be a shift to type I gene expression (including CD8, 
TBET, IFNG, and IL-1B included in the panel) and decrease in GATA3 and type II gene expression similar 
to what we have seen with bexarotene therapy in the TgMMTV-neu mouse (Fig 3).

Exploratory Endpoint 
 
For participants 6-25, we will determine if 9cUAB30 increases activated dendritic cells in the peripheral 
blood.  Three 10 mL vials of whole blood drawn in sodium heparin tubes will be obtained and shipped fresh 
to the University of Washington prior to starting the 9cUAB30 therapy and at surgery.  The University of 
Washington Tumor Vaccine Group Immune Monitoring Laboratory has developed a flow cytometry panel 
that includes CD11c-AF700, CD14-V450, CD123-PE, and HLA-DR BV605 to evaluate for antigen 
presenting cells.  As immature dendritic cells activate and mature, they increase expression of co-
stimulatory molecules CD40 FITC and CD86 PECy7 as well as percent of MHC class II receptors on their 
cell surface.62,63  We will measure the expression of CD40, CD86, and MHC II on CD11c and CD123 
dendritic cells by FACS analysis.  We expect that there will be at least a doubling in the percent of CD11c 
dendritic cells that are expressing CD40 and CD86 activation markers as that has been what we have seen 
in vitro with increasing doses of 9cUAB30 (Fig 7). 
 
It has been found that use of some Retinoids have resulted in various toxicities such as, skin toxicity, angular 
chelitis, headache, hyperlipidemia, vision changes and elevations in hepatic transaminases.  During this 
study all safety information will be obtained for participants who have taken 9cUAB30 and we will compare 
this safety profile to that seen with other Retinoids.  
8.4 
Off-Agent Criteria  
 
Participants may stop taking study agent for the following reasons: completed the protocol-prescribed 
intervention, adverse event or serious adverse event that will compromise the surgery, inadequate agent 
supply, noncompliance, concomitant medications, lost to follow-up, pregnancy or medical contraindication.

from women without breast cancer (n=5) were stimulated by increasing concentrations of (A-C) bexarotene 
and (D-F) 9cUAB30 for 48 hours.  Monocytic dendritic cells (CD11c+HLA DR+ LIN-) (A and D) and 
plasmacytic dendritic cells (CD123+ HLA DR+ LIN-) (B but not D) have increased CD40+ expression 
suggesting increased activation.   Macrophages do not show activation with either bexarotene or 9cUAB30

8.5 
Off-Study Criteria 
 
Participants may go ‘off-study’ for the following reasons: the protocol intervention and any protocol-
required follow-up period is completed, adverse event/ serious adverse event, lost to follow-up, non-
compliance, concomitant medication, medical contraindication, withdraw consent, death, determination of 
ineligibility (including screen failure), pregnancy, or subject wishes.  
 
8.6 
Study Termination 
 
NCI, DCP as the study sponsor has the right to discontinue the study at any time. If not stopped early, the 
study will be considered terminated when the final report is written.

CORRELATIVE/SPECIAL STUDIES 
 
9.1 
Rationale for Methodology Selection 
 
The primary goal of the study is to ensure that 9cUAB30 produces a biological effect in humans to justify 
pursuing more large-scale studies of 9cUAB30. To assess response to 9cUAB30, expression levels of 
biomarkers will be assessed pre and post treatment with immunohistochemistry (IHC) and Nanostring 
technology.  We have incorporated a nonrandomized matched “control” cohort to better understand baseline 
variability in biomarker analysis between diagnostic core biopsy and surgical resections.  
 
If the treatment agent 9cUAB30 is effective against breast cancer, it should reduce proliferation and/or kill 
breast cancer cells. In paraffin blocks, proliferation is assessed by immunohistochemistry via measuring 
changes in Ki67 and cell death is measured by the caspase 3 assay and routine histology. Another measure 
of proliferation is PCNA. However, all cells of breast cancer frequently stain with PCNA so it is not very 
useful. Paraffin embedded biopsy tissue will be compared with paraffin embedded tissue after definitive 
surgery following treatment with 9cUAB30.  These assays will be performed on 5 µm tissue sections from 
paraffin embedded tissues. Prior to analyzing treated cases, there will be a study of the variability of Ki67 
and caspase 3 between biopsies and definitive surgery (i.e., excision of any remaining tumor either in a 
lumpectomy or in a mastectomy). This study will be performed on retrospective samples which have not 
been treated between the biopsy and definitive surgery from each institution. Other than this, there will be 
no existing data with which to compare results of treatment with 9cUAB30 in this format of analysis. 
 
Specifically, at each institution, pretreatment core biopsy FFPE blocks containing breast cancer will be used 
to obtain 5 unstained slides of 5µm thickness for immunohistochemistry analysis to be performed at 
Wisconsin and 1 H&E stained slide, 5 unstained slides of 10µm thickness for Nanostring analysis to be 
performed at UAB. Post treatment, 1 H&E stained slide, 5 unstained slides of 5µm thickness and 5 
unstained slides of 10µm thickness will be prepared from diagnostic FFPE blocks from the definitive 
surgical resection for analysis also to be performed at Wisconsin and UAB.  
 
Additionally, each institution will provide matched samples (at the direction of UAB Pathology Core lab) 
from archival diagnostic core biopsy FFPE blocks containing breast cancer and archival FFPE blocks from 
the corresponding definitive surgical resection. Each matched case will be used to obtain 1 H&E stained 
slide, 5 unstained slides of 5µm thickness and 5 unstained slides of 10µm thickness from the archived core 
biopsy and 1 H&E stained slide, 5 unstained slides of 5µm thickness and 5 unstained slides of 10µm

thickness from the archived surgical specimen. These will be prepared and sent to Wisconsin and UAB as 
directed for analysis. 
 
9.2 
Comparable Methods 
 
Immunohistochemistry  
 
In paraffin sections, immunohistochemistry is the best assay for proliferation and activated caspases are the 
best assay for cell death by apoptosis. The antibody for Ki67 will be a rabbit monoclonal (SP6). We have 
experience with both SP6 and the mouse monoclonal MIB-1 antibodies and prefer SP6. The most important 
variable in measuring proliferation and apoptosis is probably the time between the end of treatment with 
9cUAB30 surgery and definitive surgery. This should be as constant as practicable. 
   
Similarly, the best time to measure changes in proliferation is a function of the time after therapy with 
9cUAB30 ends and the length of therapy with 9cUAB30. An answer to this will also require a pilot study. 
 
Nanostring 
 
Gene expression analysis will be performed using the Nanostring nCounter platform.  The Nanostring 
nCounter Dx Analysis System delivers direct, multiplexed measurements of gene expression through the 
digital readout of the relative abundance of mRNA transcripts isolated from formalin fixed paraffin 
embedded (FFPE) tissue.  Multiple validation studies of this technology compared q-PCR, microarray, and 
Nanostring techniques.   
 
Results showed that Nanostring technology achieved superior gene expression quantification results 
compared to arrays and/or IHC in archived FFPE samples.37 38-40 Furthermore, robust data could be obtained 
from RNA extracted from 30 year old archived FFPE tumors.41  These reports support the utility of the 
Nanostring nCounter platform to yield highly robust and reproducible data.      
 
Flow Cytometry (Exploratory only):  
 
Whole blood will be processed from baseline and prior to surgery and frozen for batch evaluation.  Dendritic 
cell activation will be evaluated by a dendritic cell antibody panel.  For evaluation of immune components 
in whole blood, 12 color flow cytometry will be performed using an LSR2 Flow Cytometer (BD 
Biosciences).  Batched flow cytometry using validated methods from the Cancer Immunotherapy Trials 
Network will allow for samples from both baseline and after treatment with 9cUAB30 to be run with the 
same controls and to allow direct comparison.  Flow cytometry is the best method to measure activation 
markers in the peripheral blood of individual dendritic cell populations (Autissier Cytometry 77A:410 
2010).

Each institution will provide unstained slides from archival formalin-fixed paraffin embedded blocks 
containing malignant tissue that will support provision of ~ 100 mg, from both the pre-surgical core biopsy 
as well as the definitive surgical resection as detailed in section 10.2.1.  A total of 5 unstained slides of 5µm 
thickness (for the UWCCC TRIP lab) and 1 H&E stained slide, 5 unstained slides of 10µm thickness (for 
the Yang lab) will be required.  If the core biopsy will not support the preparation of the requested slides, 
alternatively, 1 H&E stained slide, and 5 unstained slides at 5 µm will be accepted.   The preparation of 
these slides will be coordinated with the UAB Tissue Biorepository Laboratory and UWCCC TRIP to 
assure the slides are prepared and submitted shortly before the analysis will occur.   
 
Nanostring analysis 
 
Using the Nanostring platform, the gene expression of the following genes will be assessed:  
- 
Potential biomarkers of rexinoid activity: ABCA1, ABCG1, RAR,  SREBP1c, cyclinD1, IGFBP6 
- 
Potential biomarkers of response to 9cUAB30: RET, MEN1, mTOR, AKT1, AKT2, 4EBP1, eIF4G1, 
S6K, IGFBP5, TGFbR1, PPAR, PPAR 
Additionally, 5 housekeeping genes (GAPDH, TUBB, PGK1, GUSB, and CLTC) will be used as 
internal controls. 
-   Pan-cancer immune profiling panel 
 
Slides will be processed with the same protocol designed by Nanostring for their FDA cleared Prosigna 
Breast Cancer Prognostic Gene Signature Assay.  Briefly, H&E stained slides will be examined by Dr. Al 
Diffalha, who will determine the tumor surface area and delineate the tumor.  Tumor surface area will be 
used to estimate the amount of tissue required. Sections will then be macrodissected and RNA is extracted 
using a commercially available FFPE kit from Roche (also used exclusively by Nanostring) and quantified.  
As little as 50ng of high quality RNA can be used to hybridize overnight with gene-specific probe pairs 
consisting of a Reporter and Capture probes.  The fluorescent Reporter probe consists of a 35-50 base probe 
sequence that is complementary to the mRNA target and a DNA sequence that hybridizes to a “color code” 
unique to each target. After hybridization, the samples are purified through a series of automated magnetic 
bead capture steps and washes on the nCounter Prep Station, bound to the surface of a nCounter Cartridge 
(via the Capture probe) and subjected to a high voltage to align and immobilize the Reporter probes to be 
read in the nCounter Digital Analyzer.    
 
Flow Cytometry Analysis: 
 
The blood for flow cytometry analysis of dendritic cell activation will be performed from SOPs form the 
University of Washington Tumor Vaccine Group.  In brief, 30 mL of blood will be collected at baseline 
and after 9cUAB30 therapy prior to surgery and sent directly to the University of Washington Immune 
Monitoring Laboratory where it will be frozen and stored in liquid nitrogen.  Samples will be thawed and 
evaluated in batches.  The samples will be stained with a cell surface marker dendritic cell panel including 
CD11c AF700, CD123 PE-Cy5, HLA-DR BV605, and activation markers CD40 FITC and CD86 BV650 
and fixed with 2% paraformaldehyde prior to evaluation.  The dendritic cell panel has been previously 
validated for use in clinical studies but the activation markers CD40 and CD86 will require further 
validation.  Flow cytometry will be performed on a BD Biosciences LSRII cytometer.

subject enrolled on the study – for both the slides being sent to UAB and UWCCC, and the blood and urine 
being sent to UWCCC. Each site will receive two kits as they activate the study. The CP lab will send 
additional kits to the sites as needed based on the rate of accrual.  
 
Each kit will be sent in a box to each site. Each box will contain: 
• 
Styrofoam cooler for blood and urine samples and airbill – which go to UWCCC  
• 
Slide mailers, shipping box and airbill for slides – which go to UWCCC and UAB 
 
The University of Washington will ship 2 kits for the 30 mL peripheral blood to each of the sites prior to 
start of the trial and then will ship further kits to the sites as needed based on recruitment.  The University 
of Washington will train the sites on packing and shipping the blood.  All blood processing and storage 
during the trial will be performed at the University of Washington and after analysis any remaining 
specimens will be returned to the Division of Cancer Prevention repository.

10.2.2 Methods for drawing and processing the pharmacokinetics of blood 
At each pharmacokinetic time point (baseline, 5 minutes post day 1 dose, 2 hours post day 1 dose and Day 
15-29 prior to surgery), draw one 3ml green top heparinized tube.  Centrifuge the tube for 10 minutes to 
separate plasma.  Divide the plasma into 2 cryovial tubes.  Label the 2 cryovial tubes with the labels 
provided in the kit.  Make sure to add the participant number, initials, and date of processing to the labels.  
Freeze the cryovial tubes at -70/ -80°C, and save for transport to the UWCCC CP Laboratory.   
10.2.3 Methods for processing the pharmacokinetics of urine  
Request the participant to void and record date and time.  Store samples immediately at 4°C.  Aliquot 
approximately 10ml of urine into a falcon tube for urine pharmacokinetics.  Freeze urine aliquot within 1-
4 hours at -70 / -80°C.  Discard any remaining urine. 
10.2.4 Methods for processing for whole blood. 
30 mL of blood will be collected from participants 6-25 at baseline and on day of surgery 
(Day 15-29) prior to surgery in green top sodium heparin tubes and shipped directly to the 
University of Washington.  Whole blood will cryopreserved in freezing media (10% 
dimethylsulfoxide and 90% media which includes 12.5% human serum albumin and 
RPMI-1640 with L-glutamine and 25 mM HEPES) and stored in liquid nitrogen until use 
in the assay.10.3

DEFINITION: AE means any untoward medical occurrence associated with the use of a drug in humans, 
whether or not considered drug related. An AE can therefore be any unfavorable and unintended sign), 
symptom, or disease temporally associated with participation in a study, whether or not related to that 
participation. This includes all deaths that occur while a participant is on a study. 
 
Please note that all abnormal clinical laboratory values that are determined to be of clinical significance 
based on a physician’s assessment are to be reported as AEs. Those labs determined to be of no clinical 
significance or of unknown clinical significance (per the physician’s assessment) should not be reported as 
AEs. Any lab value of unknown clinical significance should continue to be investigated/followed-up further 
for a final determination, if possible. 
 
A list of AEs that have occurred or might occur  can be found in §6.2 Reported Adverse Events and Potential 
Risks, as well as the Investigator Brochure or package insert.  
 
 
 
11.1 
Adverse Events 
 
11.1.1 Reportable AEs 
 
11.1.1.1 All AEs that occur after the informed consent is signed and baseline assessments are completed 
(including run-in) must be recorded on the AE CRF (paper and/or electronic) whether or not related to study 
agent. 
 
How to obtain blood pressure for the study (for study team and participants) 
 
• 
Use the wrist blood pressure monitors provided for the study to record all readings for the study.  
• 
When the blood pressure is being obtained, the participant should sit for at least 5 minutes before 
taking the blood pressure.  
• 
Place the cuff on participant’s wrist as instructed in the wrist blood pressure monitor’s manual.  
• 
The arm used to measure blood pressure should be supported and ensure the arm is at heart level.  
• 
The participant should be instructed not to talk during this time, keep their back rested and legs 
uncrossed. 
In the case of an elevated blood pressure, in which it was repeated, the average of the values should be 
used for Adverse Event determination.  
 
11.1.1.2 AEs not related to surgery that occur from the time of surgery through the 4-5 week post surgery 
follow-up visit must be recorded on the AE CRF (paper and/or electronic) whether or not related to study 
agent.  
 
11.1.1.3 All SAEs, including all hospitalizations, during the study period will be reported as per DCP SAE 
reporting procedures, with the following exception:  
 
Hospitalization for planned surgery will not be reported. However, if this hospitalization event lasts longer 
than the usual period at the institution (as determined by the Site Principal Investigator or Sponsor), it will 
be reportable as an SAE. Adverse events (AEs) relevant to the prolongation of this hospitalization will also 
be collected and reported on AE CRFs. 
 
11.1.2 AE Data Elements: 
The following data elements are required for AE reporting.

Serious Adverse Events  
 
11.2.1 DEFINITION: Regulations at 21 CFR §312.32 (revised April 1, 2014) defines an SAE as any 
untoward medical occurrence that at any dose has one or more of the following outcomes: 
 
• 
Death 
• 
A life-threatening AE 
• 
Inpatient hospitalization or prolongation of existing hospitalization 
• 
A persistent or significant incapacity or substantial disruption of the ability to perform normal life 
functions 
• 
A congenital anomaly or birth defect 
• 
Important medical events that may not be immediately life-threatening or result in death 
or hospitalization should also be considered serious when, based upon appropriate 
medical judgment, they may jeopardize the participant and may require intervention to 
prevent one of the other outcomes.

STUDY MONITORING 
 
12.1 
Data Management 
All of the procedures outlined in the University of Wisconsin Chemoprevention Consortium standardized 
Data Management Plan (approved 09/23/2019) will be followed in this protocol.  Please refer to this 
document for additional details on data management procedures.   
This study will report clinical data using the OnCore web-based application clinical trials/database.  OnCore 
will be the database of record for the protocol and is subject to NCI and FDA audit.  All OnCore data entry 
will be performed at the CLO where staff is trained in OnCore per our DMP and applicable regulatory 
requirements such as 21 CFR; Part 11. 
 
12.2 
Case Report Forms 
All data entry will be performed by the Consortium lead Organization (or CLO, the University of 
Wisconsin) staff.  Participant data will be entered into protocol-specific electronic case report forms 
(CRF’s), developed from the standard set of DCP Chemoprevention CRF Templates and utilizing NCI-
approved Common Data Elements (CDE).  PO’s will be required to submit data for quality assurance review 
and entry into the OnCore database within 10 business days of each study encounter.  All data entry will be 
completed by the CLO within 15 business days of the scheduled visit, as defined in the approved master 
Data Management Plan. Amended e-CRFs will be submitted to the DCP Protocol Information Office for 
review and approval. 
   
12.3 
Source Documents 
The CLO will provide participating sites with standardized, pre-printed source document forms that serve 
a dual role as source documents and as CRF’s, which may be used to ensure that all data items are collected.  
These pre-printed source document forms must be signed and dated by the person completing the form.  If 
the policy at the site mandates the use of an approved local institutional form or source documentation, the 
local institutional form may be submitted for the forms supplied by the CLO, as long as all required data 
points are included on the local institutional form.  All de-identified source documents will be sent

12.4 
Data and Safety Monitoring Plan 
The standard University of Wisconsin Chemoprevention Consortium DSMP was approved by the DCP on 
03/20/2018.  In addition to the standard procedures outlined in the consortium DSMP, we will be modifying 
the DMP and will perform additional monitoring of data for this trial.   
 
12.5 
Sponsor or FDA Monitoring 
The NCI, DCP (or their designee), pharmaceutical collaborator (or their designee), or FDA may 
monitor/audit various aspects of the study. These monitors will be given access to facilities, databases, 
supplies and records to review and verify data pertinent to the study.  
 
12.6 
Record Retention 
 
Clinical records for all participants, including CRFs, all source documentation (containing evidence to study 
eligibility, history and physical findings, laboratory data, results of consultations, etc.), as well as IRB 
records and other regulatory documentation will be retained by the Investigator in a secure storage facility 
in compliance with Health Insurance Portability and Accountability Act (HIPAA), Office of Human 
Research Protections (OHRP), Food and Drug Administration (FDA) regulations and guidances, and 
NCI/DCP requirements, unless the standard at the site is more stringent. The records for all studies 
performed under an IND will be maintained, at a minimum, for two years after the approval of a New Drug 
Application (NDA). For NCI/DCP, records will be retained for at least three years after the completion of 
the research. NCI will be notified prior to the planned destruction of any materials. The records should be 
accessible for inspection and copying by authorized persons of the Food and Drug Administration. If the

STATISTICAL CONSIDERATIONS 
 
13.1 
Study Design/Description 
 
We aim to enroll 24 ER+ participants and 12 ER- participants for a total of 36 participants.  We plan to 
“pilot” the 240 mg dose in 5 initial participants with planned assessment of Cmax (Tmax usually at 2 hours) 
at 2 hours post initial dose (see section 2.3 for further information).  In the original 9cUAB30 Phase I study, 
we saw a flattening of the otherwise linear PK concentration curve; there was a mean Cmax of 957 ng/ml 
(SD 611) at the 240 mg dose level, similar to the mean Cmax of 983 (SD 434) for the 160 mg dose level.  
If Cmax had continued to be linear, we will have expected to see a Cmax of 1668 at the 240 mg dose level 
(calculated using linear regression with a forced intercept of 0, omitting the 240 mg level).  We will test the 
hypothesis H0: Cmax=957 (concentration curve is flat) vs the hypothesis HA:Cmax=1668 (concentration 
curve is linear) with a one-tailed one-sample Student t-test. Assuming a standard deviation of 611, we will 
have 0.69 power to reject H0: Cmax=957 given that the true mean Cmax is 1668 using a one-tailed one-
sample t-test of level 0.05.  Based on the results of this analysis, if we do not reject H0 and the dose gets 
changed to 160 mg after enrolling 5 participants, 36 additional participants will be enrolled to meet total of 
36 participants for data analysis on 160 mg dose and 41 participants total in the study. If we reject H0 we

will continue at 240 mg/day and enroll 31 more subjects. 
 
This is a single arm open label pre-surgical “window trial” of the novel rexinoid 9cUAB30.  The primary 
objective is to evaluate whether therapy with 9cUAB30 substantially reduces proliferation in breast cancer 
cells. To test the hypothesis that proliferation decreases in 9cUAB30 treated cases, we plan to examine 
Ki67 from newly diagnosed breast cancer patients. For each enrolled participant, we will obtain baseline 
core biopsy tissue samples and post-treatment definitive surgical tissue samples.  To account for potential 
confounding variability associated within the tumor as a result of core biopsy, we plan to include a matched 
historical nonrandomized “control” group which will have an initial sample as well as post-surgical sample. 
This matched group will come from archived tissue samples of core biopsy and definitive surgical tissue 
samples available at each participating Institution. The primary endpoint will be the absolute change in 
Ki67 expression in each treated participant and matched “control” pair.   
 
The primary analysis will compare the difference in absolute change in Ki67 between treatment and 
matched “control” group using a one-tailed paired t-test or Wilcoxon signed-rank test, as appropriate, at a 
significance level of 0.05.  We chose the one-tailed test as we are only interested in detecting the reduction 
in Ki67 expression level with 9cUAB30 as compared to controls. 
 
13.2 
Randomization/Stratification  
 
We aim to enroll 24 ER+ participants and 12 ER- participants for a total of 36 participants.  As this is a 
non-randomized trial, stratification for randomization is not applicable.  One of the analyses to be 
performed will be stratified by estrogen receptor status.  
 
13.3 
Accrual and Feasibility 
 
According to Dowsett et al., there was a mean decrease in Ki67 of 59.5% and an estimated standard 
deviation (SD) of 57.5% with tamoxifen, the least effective among tamoxifen alone, anastrozole alone, and 
tamoxifen/anastrozole combination.34As we do not know if 9cUAB30 will have as much of a decrease as 
tamoxifen, we will use a range of more conservative estimates, from 50-75% of 59.5%, or 29.8-44.6%. 
According to Chen et al., there was a mean increase in Ki67 of 1.7% with a SD of 7.6% based on three 
untreated observations with the time interval comparable to the proposed study.43 However, three 
observations for estimation of SD is not reliable.  Instead we used the widest interval-based SD estimate of 
14.8% (from the 2-4 day interval), to be conservative.   We also conservatively used an estimate of 0% for 
change in the control group instead of 1.7%, again, because of the sample size consideration.  
 
Since we are using matched pairs, we needed to estimate the mean and SD of the difference between the 
matched pair. With 0% as our control estimate, the estimate of the range of the mean difference is thus 
29.8-44.6%.  The SD is estimated using the equation √𝜎𝑇2 + 𝜎𝐶2 −2ρσ 𝑇σ 𝐶 where σ𝑇 is the SD of the 
treatment group, σ𝐶 is the SD of the control group, and ρ is the correlation between the matched pair.  The 
value of this equation increases as ρ decreases in value, so an estimate using a smaller correlation coefficient 
is more conservative.  This correlation is unlikely to be negative.  Also, if the effect on Ki67 is not dependent 
on the factors that will be used to choose the matched controls, the correlation is likely to be close to 0.   
For these reasons, we use 0 as the estimate of ρ; this gives an estimate of 59.4% for the SD of the difference 
between the matched pair.  
 
We will enroll 36 participants, and obtain 36 matched pairs.  Stratified analyses will be conducted if we 
reach a minimum of 12 participants (and matched pairs) with ER-.  Assuming 20% of the participants 
cannot be evaluated at the end of study due to dropout or unevaluable/unavailable specimen, we will have 
approximately 28 participants, with 9 participants with ER- and 19 with ER+.  The range of mean difference

in the change of 29.8-44.6% and the estimated SD of 59.4% result in an effect size ranging from 0.502-
0.751.  The table below shows the attainable power of a one-tailed level 0.05 paired test under various effect 
sizes.  With 32 participants, the study will have 0.82-0.98 power to detect the range of effect size of 0.502-
0.751. With the 9 participants and matched controls in the ER- group, there will be a power of 0.39-0.65 to 
detect an effect size range of 0.502 -0.751 between the treatment group and the matched controls.  With the 
19 participants and matched controls in the ER+ group there will be a power of 0.67-0.93 to detect the same 
effect size range. Because of the nature of the study being exploratory, we are not making adjustment for 
multiplicity of testing in subgroups defined by ER status.

Primary Objective, Endpoint(s), Analysis Plan 
 
The primary objective will be to evaluate if there is a significant decrease in proliferation (Ki67) expression 
in breast cancer cells from baseline to post-exposure in participants treated with 9cUAB30 compared with 
matched controls. The primary endpoint is the absolute change from baseline to post-exposure in 9cUAB30 
treated and matched controls in Ki-67 in breast epithelial cells obtained by needle core biopsy.  The 
baseline, post-exposure, absolute change in Ki-67, and difference in absolute change between the treated 
and matched controls will all be summarized with descriptive statistics.  The primary analysis will compare 
the absolute change in Ki-67 between treatment and matched “control” group using a one-tailed paired t-
test or Wilcoxon signed-rank test, as appropriate, at a significance level of 0.05.   
 
13.5 
Secondary Objectives, Endpoints, Analysis Plans 
 
The first of secondary objectives is to evaluate if there is a difference in the change in apoptosis (caspase 
3) from baseline to post-exposure in breast cancer epithelial cells in participants treated with 9cUAB30 
compared with matched controls.  In the second of secondary objectives, we will examine the differences 
in gene expression from baseline to post-exposure breast cancer samples using a custom gene panel from 
Nanostring Technologies. Examined genes will be selected as described below and will include 23 genes. 
Prospective biomarkers on the panel will include (A) biomarkers associated with cell proliferation or 
apoptosis: PCNA, p21, p27, caspase 3;  (B) potential biomarkers of rexinoid activity reported in published 
studies: ABCA1, ABCG1, RARβ, SREBP-1c, cyclin D1, IGFBP6; (C) potential biomarkers of response to 
9cUAB30 as defined in our preliminary studies: RET, MEN1, mTOR, AKT1, AKT2, 4EBP1, eIF4G1, 
S6K, IGFBP5, TGFβR1, PPARα, PPARγ; and (D) housekeeping genes for normalization: GAPDH, TUBB, 
PGK1, GUSB, and CLTC. Additionally, as possible, we will perform IHC for a subset of 5 of the most 
differentially regulated genes found on Nanostring to verify that gene expression data also results in protein 
differences. 
 
One of the secondary objectives will be to examine if the Cmax at day 1 is increased from 957 ng/ml by 
reducing the number of capsules for the 240 mg dose level. The endpoint for this objective is Cmax 
measured at day 1.  This will be tested using a one-tailed one-sample Student t-test.

Observed toxicities seen in this study will be compared with those known to occur from retinoid use.  This 
comparison will be qualitative by necessity and descriptive in nature.  As such these will be described in 
descriptive statistics. 
  
13.6 
Reporting and Exclusions 
 
All participants who receive any 9cUAB30 will be analyzed for adverse events. Subjects that maintain 90% 
compliance for the time period beginning day 1 and ending on the day before surgical intervention will be 
considered compliant. Compliance will be measured though pill counts conducted by the study coordinator 
and recorded in the CRF. For biomarker modulation, all participants that have evaluable pre- and post-
treatment samples will be included in the analysis. Compliance and availability of evaluable samples for 
biomarker studies will be included in descriptive statistics.  
 
13.7 
Evaluation of Toxicity 
 
All participants will be evaluable for toxicity from the time of their first dose of 9cUAB30. The toxicity 
will be tabulated by severity with descriptive statistics.  
 
13.8 
Evaluation of Response 
 
All participants included in the study will be assessed for response to intervention with 9cUAB30, 
specifically decrease in proliferation and increase in apoptosis.  All of the participants who met the 
eligibility criteria will be included in the main analysis. All conclusions regarding efficacy will be based on 
all eligible participants. 
 
13.9 
Interim Analysis 
 
There is no planned interim analysis of the primary endpoint of the study. Safety data will be monitored by 
the consortium’s data monitoring committee.  
 
There will be an interim analysis after first 5 participants complete the study at dose 240 mg. This will be 
to analyze the Cmax and evaluate toxicity data collected for the first 5 participants. 
 
The dose of the study will be reduced to 160 mg if one of the following criteria is met:  
 
1. If the mean Cmax is not >957 ng/mL 
2. If ≥ 2 subjects experience grade 2 hypertriglyceridemia of any attribution 
 
If the study dose is reduced to 160mg due to the toxicity criteria at 240mg, then another cohort of 
5participants will be evaluated only for toxicity.  
 
If any subjects experience grade 4 or higher toxicity, the study will be suspended for accrual. The study 
chair will consult with the DSMC for study termination or other course of action.  The PI will work with 
the NCI DCP Investigators to make a decision in consideration of the DSMC’s recommendation.
