Objectives
Primary:

To test the non-inferiority of PDT to standard of care surgery by comparing the 
rate of tumor response after PDT to those observed after surgery, at 24 months 
post treatment.
Secondary:

To determine quality of life (QoL) at 6, 12, 18, and 24 months post PDT or 
surgery.

To assess the toxicity using the CTEP NCI Common Terminology Criteria for 
Adverse Events (CTCAE Version 4.0).
Tertiary:

Immune markers (T cells).

To investigate the correlation of diffuse reflectance optical spectroscopy with 
tumor response to PDT (Appendix B).
Study Design

This is an open-label, randomized, multicenter Phase II study of HPPH-mediated 
PDT in patients with lesions that are diagnosed as previously untreated T1 N0 or 
T2 N0 SCC of the oral cavity. 114 participants will be randomized (1:1) to surgery 
(57) or PDT with HPPH (57). The randomization will be done at RPCI by the 
biostatistician.

Participants will be treated on an outpatient basis. Rarely, participants may require 
hospitalization, but this will be decided on a case by case basis. All participants 
will meet the inclusion and exclusion criteria.

Participants randomized to PDT with HPPH will be administered a single dose of 
HPPH at 4 mg/m2 via slow intravenous (IV) infusion over 1 hour. Approximately 
1 day later, the target tumor will be illuminated with a 665-nm laser light at dose 
of 140 Joules/cm2 delivered at a fluence rate of 150 mW/cm2. The participants 
will be scheduled to have clinical examination at 1 week, 4 - 6 weeks, 12-16 
weeks, and at 24 months post therapy. Pathological evaluation will be conducted 
by taking a 3-mm punch biopsy from the treated region during the 12-16 weeks 
clinical visit. In the event that a suspicious lesion is observed, the participants will 
be scheduled for a biopsy at the discretion of the treating physician. Participants 
will receive standard curative therapy 6 weeks after failing to respond to PDT with 
HPPH. Tumor response will be determined according to the revised response 
evaluation criteria in solid tumors (RECIST v1.1).

Target Accrual and 
Study Duration
A maximum of 114 participants at 3 sites, including RPCI, will be enrolled. Accrual is 
expected to take up to 4 years. Each participant is expected to be on the study for two 
years and will be followed according to NCCN guidelines.
Study Procedures
Disease Evaluation: Baseline and as per the NCCN guidelines for T1/T2 SCC of the 
head and neck.
Quality of Life Questionnaire: Baseline, post treatment at 12 - 16 weeks and 6, 12, 
18, and 24 months.
Hematology: Baseline.
Chemistry: Baseline.
Performance Status: Baseline, post treatment at 12 - 16 weeks, and at follow-up 
visits.
Clinical Examination: Baseline and post treatment at 1 week, 4 - 6 weeks, 
12 - 16 weeks. We will follow the subjects according to the NCCN guidelines for 
patients with T1/T2 SCC, i.e. every 3 – 4 months (year 1), 3 – 6 months (year 2). 
Vital Signs: Baseline, Day 0, post treatment at 1 week, 4 - 6 weeks, 12 - 16 weeks, and 
at follow-up visits.
HPPH Infusion: Day 0
Blood Samples:  Day 0, 7, and 4-6 weeks  
Optical Spectroscopy:  Day 1 
Laser: Day 1
Adverse Events: From administration of study drug or surgery until 30 days after 
receiving study drug or surgery.
Statistical Analysis
The primary objective of this study is to test the non-inferiority of PDT to standard of 
care by comparing the rate of tumor response after PDT to those obtained after surgery.
This is a randomized multicenter Phase II trial with PDT with HPPH for the treatment 
of T1/T2 N0 primary tumors of the oral cavity. The design is based on a test for non-
inferiority of PDT compared to standard of care with regards to tumor response. 
Justification for use of a non-inferiority trial is that PDT may be viewed as a potential 
replacement for standard of care if it is established as less toxic than the standard of 
care yet still providing acceptable efficacy.
Sample Size Determination: The samples sizes of the trial are set at 57 in each of the 
standard of care and PDT groups. With the proposed sample sizes, there is 
approximately 80% power associated with the non-inferiority test when the true tumor 
response probabilities are equal to 85% in both groups.
Randomization: The randomization scheme will be generated at RPCI by the 
biostatistician. 114 participants will be randomized at a ratio of 1:1 to be treated with 
either standard of care surgery (57) or PDT with HPPH (57).
Efficacy Analysis: Objective tumor response will be tabulated overall. All participants 
who randomized to PDT treatment or surgery will be evaluable for response. Tumor 
response will be determined by comparing the photographs of the treated site (with 
reference ruler) before and after PDT or surgery.
Safety Analysis: The frequency of toxicities will be tabulated by grade across all 
cycles. All participants who randomized to HPPH PDT will be considered evaluable 
for toxicity.

BACKGROUND
1.1
CANCER OF THE ORAL CAVITY
Cancer of the head and neck is the sixth most prevalent cancer worldwide, with an incidence 
exceeding half a million cases annually.1 The most recent data from the NCI Surveillance, 
Epidemiology, and End Results (SEER) Program predicted that 48,330 men and women (34,780 
men and 13,550 women) would be diagnosed with and 9,750 men and women would die of cancer 
of the oral cavity and pharynx in 2016.2 These numbers represent an estimated 16.8% increase in 
the incident and 23.57% in death rate when compared to the published statistics in 2013 
(41,380 were diagnosed and 7,890 were expected to die from head and neck cancer).3 The steady 
increase in incidents and death rate suggest that there is an urgent need to improve the treatment 
for this specific cancer.  
1.2
STANDARD TREATMENT FOR EARLY STAGE CANCER OF THE ORAL 
CAVITY 
Surgery and radiotherapy are standard treatment modalities for T1/T2 oral cavity cancer (OCC).4 
Several studies demonstrated that surgery is the preferred treatment for oral squamous cell 
carcinoma (SCC), yielding superior 5-year survival rates when compared to radiation therapy.4,5 
Furthermore, the sequelae of radiation therapy such as xerostomia, chronic dental decay and risk 
of mandibular osteonecrosis remain long after the patient is “cured,” reducing the patients’ quality 
of life (QoL).6 
Effective surgical treatment of OCC requires wide local resection of the primary tumor with clear 
surgical margins. In order to secure tumor free margins the surgical procedures remove additional 
functional tissue often affecting speech and swallowing. Following the initial surgery, the risk 
of local recurrences is as high as 20%.7-9 Local recurrences are usually treated with further 
surgery, requiring more mucosal resection. Patients that have been cured with standard therapy 
also have a significant risk of developing second primary tumors, which has been associated with 
poor prognosis.10-12 Treatment of second primaries will increase patient morbidity. Currently, 
younger patients are being diagnosed with oral cancer, and their QoL is severely affected by 
standard of care therapies.6,13 It is important to provide this patient population with a first line 
therapy that will not cause irreversible long-term toxicities, and if failed, can be followed with 
standard surgery to improve the chance of cure.
Photodynamic therapy (PDT) can result in good local control of early stage OCC with minimal 
loss of tissue volume and excellent long-term healing that is expected to improve QoL.14-16 Our 
experience (including our collaborator, Dr. Biel) suggest that patients who failed to respond to 
PDT can be safely salvaged with standard surgery.17,18 
1.3
PHOTODYNAMIC THERAPY FOR EARLY STAGE HEAD AND NECK 
CANCER 
Numerous studies over the past 25 years have used photodynamic therapy (PDT) to treat early 
stage oral and oropharyngeal carcinomas.  While many of the early studies were single site with 
small numbers of patients, in 2004 a major prospective multi-center trial was conducted using 
mTHPC-PDT to treat early (carcinoma in situ, Cis -T2) disease.19 A total of 114 patients were

treated with an overall complete tumor response (CR) of 85% which was maintained in 85% of 
the patients for 1 year.  In 2010 Biel reported the cumulative results of treatment of Cis-T1 
carcinomas with Photofrin-PDT to be a CR of 94% with a 5 year response of 90%.20 A review of 
the literature showed that, between 1990 and 2013, 729 patients were treated with PDT with a 
cumulative overall tumor response rate of 0.85 (Table 1).  Importantly, healing was reported to be 
excellent and salvage treatment carried out by either surgery or repeated PDT resulted in 100% 
CR.20 Side effects were largely limited to photosensitivity and pain at the treatment site, which 
was easily managed by analgesics.  Photosensitivity was more pronounced and last longer when 
Photofrin was used; 20  however second generation photosensitizers, mTHPC and HPPH, resulted 
in only mild-moderate photosensitivity.21 Importantly, several studies have shown that PDT results 
in fewer treatment-associated morbidities that conventional therapies, including little to no nerve 
damage, minimal scarring and retention of organ function.18-22 The organ sparing nature of PDT 
has the potential to result in fewer complex reconstructive surgical interventions.  
Although no direct comparison studies showing superiority or at least non-inferiority to the 
standard of care (SoC) modalities of surgery or radiotherapy have been conducted, single site 
and retrospective studies have compared responses after PDT vs. surgery in early stage oral 
cancer. Karakullukcu et al. 23 found no significant difference in treatment outcome between PDT 
(n=55) and surgical removal (n=43) of T1s-T2 oral cancer.  A multicenter retrospective meta-
analysis of 126 PDT and 56 surgical T1 cases demonstrated a comparable CR and no significant 
differences in overall survival were observed between the two modalities.24
Thus, the breadth of experience in treatment of early stage oral cancer with PDT suggests that 
early oral malignancies are amenable to this non-invasive therapy and that the therapy can result 
in comparable outcomes to the SoC.  However, these findings need to be confirmed in a 
multicenter, randomized clinical trial.

While PDT with the FDA-approved drug porfimer sodium is a highly effective treatment modality, 
the persistence of porfimer sodium in skin and associated photosensitization necessitates complete 
protection from sunlight and other sources of bright light for periods up to 90 days. Further, 
porfimer sodium is activated by light at 630 nm, which is suboptimal for tissue penetration. These 
drawbacks have led to a search for other photosensitizers without these limitations.39
RPCI’s PDT center evaluated over 400 new photosensitizers as possible successors to Photofrin®. 
HPPH was identified in a preclinical quantitative structure-activity relationship study to be the 
most effective photosensitizer among a series of homologues with different numbers of methylene 
groups on the ether function.40

CLINICAL STUDIES: HPPH
1.5.1
PHARMACOKINETICS (PK) 
A detailed description of the PK studies, results and analysis, can be found in section 5.2 of the 
Investigator Brochure.   
One study in 25 cancer patients revealed estimated mean population α and β half-lives (95% 
confidence intervals) of 7.77 hours (3.46 - 17.6 hours) and 596 hours (120 - 2951 hours), 
respectively.41 No metabolites were detected in serum. A more extensive study of skin 
photosensitivity in 48 patients receiving HPPH doses of 2.5 - 6 mg/m2 and solar simulator light 
doses from 44.4 - 133.2 J/cm2 demonstrated that one day after drug administration the highest drug 
and light doses elicited a response of only erythema without edema. With over 70 patients treated 
to date we have found that (a) HPPH at doses of 2.5 - 6 mg/m2 has no systemic toxicity; (b) HPPH 
at doses of 3 mg/m2 and higher (to 6 mg/m2) approaches the effectiveness of Photofrin® (no head 
to head comparisons have yet been carried out), and (c) HPPH does not induce long-term cutaneous 
photosensitivity, based on in-house solar simulator testing and patient input.

1.5.2
THE HPPH DOSE
In this protocol the participants will be treated with HPPH at fixed dose of 4 mg/m2. This dose is 
based on 5 studies, balancing safety and efficacy considerations, where HPPH-PDT was 
employed in the treatment of esophageal cancer - 2 studies in obstructing disease and 3 studies in 
high grade dysplasia, CIS and early adenocarcinoma.  The number of patients enrolled per HPPH 
dose was as follows: 11 at 6 mg/m2, 3 at 5 mg/m2, 36 at 4 mg/m2 and 32 at 3 mg/m2.  All were 
treated with 150 Joules/cm2.  The percentages of SAEs possibly, probably and definitely related 
to PDT were in order 46%, 33%, 28% and 28%, respectively.  Additionally, in the studies of 
high-grade dysplasia, CIS and early adenocarcinoma, 72% of complete responses were observed 
at 1 year at 3 and 4 mg/m2 combined, while no complete responses were observed at 5 or 6 
mg/m2.  There was no statistical difference in outcomes between 3 and 4 mg/m2 (Nava et al., 
Lasers in Surg. Med. 43, 705-12, 2011).42 The latter is likely due to photochemical oxygen 
depletion in tissue with high photosensitizer levels, which limits photodynamic action.
1.5.3
THE LIGHT FLUENCE RATE AND DOSE FOR EARLY STAGE HEAD AND 
NECK CANCER
Recently, RPCI has completed 3 Phase I studies of PDT with HPPH in the treatment of HNSCC. 
In the first study, (NCT00670397) PDT with HPPH was used intra-operatively in patients with 
resectable, primary or advanced recurrent SCC of the head and neck.43 This was a dose escalation 
study, where the drug dose was 4 mg/m2 and light dose was increased from 30 - 75 J/cm2. In this 
study, no serious adverse event was reported. The treatment was found to be safe at the maximum 
light dose of 75 J/cm2. Furthermore, major neurovascular structures and blood vessels were 
irradiated with the laser light during the PDT, but no carotid artery ruptures or cranial nerve injuries 
were observed, demonstrating that PDT with HPPH does not induce irreversible damage to healthy 
vital structures. This study also observed excellent healing of the overlaying skin in the 2 subjects 
that experienced skin burns as an adverse event. This healing was attributed to the fact that HPPH 
is not transported into fibroblasts.44 Thus, the native tissue that replaces the cancer cells regains its 
normal functions, significantly limiting function loss and minimizing scar formation.
In other Phase I studies, PDT with HPPH was used for dysplasia and T1 squamous cell carcinoma 
(SCC) of the oral cavity and oropharynx. Both trials, carried out at RPCI from April 2008 to 
June 2012, used HPPH at a fixed, previously determined dose of 4 mg/m2 administered 
systemically 20 – 28 hours before light delivery. In NCI-2010-02401 the light dose was escalated 
from 50 J/cm2 to 75 J/cm2, 100 J/cm2 and 125 J/cm2. In NCI-2010-01493 the light dose range was 
100, 125 and 140 J/cm2. Both trials had identical 3+3 designs, with an expanded cohort at 
140 J/cm2. Three courses of treatment were allowed for each oral lesion, with at least 6 weeks 
between treatments. Patients could have more than one lesion treated. The primary objectives were 
to establish the safety profile, to determine any dose-limiting toxicities (DLTs), and the maximum 
tolerated light dose (MTD). Secondary objectives were the determination of HPPH levels in blood 
and in the tumor tissue at the time of treatment, the extent of PDT-induced STAT3 crosslinking in 
the treated tissue, and the pathological treatment response as determined by biopsy at 3 months 
post treatment.
All patients who received PDT with HPPH reported the expected pain and edema at the treatment 
site, with pain lasting up to 4 weeks. Two patients in NCI-2010-02401 had Grade 3 edema at the 
application site at a light dose of 125 J/cm2, and one experienced respiratory distress shortly after 
illumination. This patient had presented with severe trismus from prior therapy, which

compromised precise light delivery and dosimetry to the lesion, which was located on the palate. 
The patient underwent a tracheostomy and recovered rapidly and completely without sequelae. 
This event, however, led to the closing of the protocol and addition of severe trismus as an 
exclusion criterion in NCI-2010-01493. Two patients in NCI-2010-01493 experienced Grade 3 
edema at the application site at 140 J/cm2, and one patient at that light dose experienced Grade 3 
ulceration. These adverse effects were temporary and resolved completely. Most patients chose a 
liquid or pureed diet due to pain for several days after treatment, but no medical intervention to 
support alimentation was needed. Mild sunburn reactions due to non-compliance with sun-
protection instructions were experienced in 1 patient in NCI-2010-02401 and 3 patients in 
NCI-2010-01493. An MTD was not reached at the highest planned dose level, but further 
escalation was forgone due to the danger of unacceptable swelling and ulceration.
The response to therapy for SCC is summarized in Table 1 below.

*Two lesions had complete disappearance of carcinoma but had minor remaining focal dysplasia. CR=complete 
response, PR=Partial response, SD=stable disease, as defined in Section 9.3 of this protocol.
The disease-free interval ranged from 5 to 40 months and follow-up is still ongoing. The CRs were 
also associated with increase in STAT3 crosslinking, which suggests that the responses were due 
to photodynamic reaction.45-47
The results of this study were recently published in Clinical Cancer Research (Rigual, Shafirstein 
et al. 2013).18
In this protocol the light fluence rate and dose will be fixed at 150 mW/cm2 and 140 J/cm2, 
respectively. 
1.6
RISKS AND/OR BENEFITS
For participants that will have partial or complete response to PDT, the potential benefits include 
complete clinical regression of the tumor. Participants that do not respond to PDT may not benefit 
from this treatment. There is no guarantee of the outcome nor is it possible to predict whether or 
not the participant will respond to HPPH mediated PDT.
This is a Greater Than Minimal Risk study according to IRB criteria. The most likely potential 
risks associated with the PDT are short term edema and pain.

RATIONALE
Surgical resection and radiotherapy are front line therapies for T1 and T2 oral cavity cancer. 
However, these therapies are associated with multiple morbidities and impaired QoL issues such 
as alteration of speech, dysphagia and xerostomia. PDT, which involves the activation by light of

a tumor-localized photosensitizer, has proven to be an effective local treatment for a range of solid 
tumors. It has the potential to become an effective first line treatment modality for this disease for 
the following reasons: it is minimally invasive, has low toxicity, is not associated with any long-
term morbidity and is repeatable. Importantly, it allows the physician to reserve conventional, 
more toxic treatments such as radiotherapy and chemotherapy for later application, if needed.
The purpose of this multicenter study is to test the non-inferiority of PDT with HPPH to standard 
of care by comparing the rate of tumor response and QoL after PDT to those obtained after surgery 
in participants with previously untreated T1/T2 N0 SCC of the oral cavity.
Phase I studies have demonstrated that this treatment is safe. These studies also determined the 
safe drug and light dosages: 4 mg/m2 and 100 - 140 J/cm2, respectively. Data also suggest that 
early stage SCC may have excellent response to this therapy (see Table 1).
In our recent study with HPPH-PDT, all the patients with T1/T2 who failed to have CR to PDT 
were successfully salvaged with surgery.18 Importantly, in patients with invasive disease who 
achieved only PR, the disease could be downgraded to dysplasia, thus minimizing salvage surgery.  
While all studies with HPPH-PDT to date have been Phase I studies, the response to PDT is swift 
and all patients, with few exceptions, have been assessed for response by pathological analysis.
We believe that PDT with HPPH is a viable option to treat patients with T1/T2, because:

HPPH-PDT is expected to be an organ sparing treatment option, and failures can be 
salvaged with surgery.  

HPPH, at clinically effective antitumor doses, is associated with significantly reduced 
cutaneous photosensitivity that rapidly declines over several days.41

The CR to HPPH-PDT is expected to be 85%, which would be comparable to cure rates 
after the initial surgery that is associated with 20% local recurrence. 7-9 

Noninvasive optical spectroscopy has potential to serve as a surrogate reporter for tumor 
response to HPPH-PDT.48
Therefore, we hypothesize that patients may choose a treatment option, such as PDT with HPPH, 
if it provides non-inferior cure rate at the time of the initial treatment.

METHODOLOGY
4.1
STUDY DESIGN
This is an open-label, randomized, multicenter Phase II study of HPPH-mediated PDT in 
participants with lesions that are diagnosed as previously untreated T1 N0 or T2 N0 SCC of the 
oral cavity. Participants will be randomized at a ratio of 1:1, to be treated with either surgery (57 
participants) or PDT with HPPH (57 participants). The randomization will be done at RPCI by the 
biostatistician. The study schema is depicted in Figure 1.
Participants will be treated on an outpatient basis. Rarely, those undergoing HPPH with PDT may 
require hospitalization but this will be decided on a case by case basis. Participants undergoing 
surgery may be hospitalized.

For those participants randomized to HPPH with PDT, a single dose of HPPH at 4 mg/m2 will be 
administered via slow intravenous (IV) infusion over 1 hour. Approximately 24 hours 
(± 4 hours) later, the target tumor will be illuminated with a 665 ± 3 nm laser (ML7710-665 
LASER, Modulight, Inc., Tampere, Finland).  A total light dose of 140 J/cm2 at a fluence rate of 
150 mW/cm2 will be delivered with a single quartz fiber optic equipped with a micro lens 
(Frontal Light Distributor Model FD1, Medlight SA, Switzerland). In areas that preclude direct 
illumination of the lesion and margins with a microlens fiber, the light will be delivered through 
a cylindrical diffuser fiber with a diffuser end (Medlight SA, Switzerland) that will be inserted 
into a 10 mm in diameter flexible applicator (Frieburg Flap, Elekta Inc. Atlanta, GA).  The 
Frieburg Flap is an FDA approved device designed to keep radiation source at constant distance 
from the treatment surface (see attached letter of approval). Multiple cylindrical fibers (in 
parallel) can be inserted into the flap to cover an entire tumor and margins in curved surfaces.  
The light through each cylindrical diffuser will be delivered at a fluence rate of 495 mW/cm 
(accounting for about 5% loss) to a total light dose of 462 J/cm, which is equivalent to surface 
illumination of 150 mW/cm2 and 140 J/cm2.  The PDT center at RPCI will provide sections of 
the Frieburg Flap that will need to be sterilize prior to use, following the manufacturer 
instructions (see attcahed).  The entire tumor and 5 mm - 10 mm margins will be illuminated. 
The remainder of the oral cavity will be shielded to avoid illumination of healthy tissue.
4.1.2
Post Treatment Evaluation
Participants will be scheduled to have a clinical examination at 1 week and within 4 - 6 weeks and 
at 12 – 16 weeks post therapy. In the event that a suspicious lesion is observed, participants will 
be scheduled for a biopsy at the discretion of the treating physician, at 4-6 weeks post treatment. 
In addition, a scheduled pathological evaluation will be conducted by taking a 3-mm punch biopsy 
from the treated tumor site during the clinical visit at 12-16 weeks post therapy.
Tumor response will be determined at 24 months post treatment. The treating physician will 
examine the clinical response and a photograph of the treatment site will be taken with paper ruler, 
to determine the reduction in the lesion size, according to RECIST v1.1. A biopsy may be taken, 
if clinically indicated. The biopsies will be processed following the standard of care pathology. A 
clinical pathologist will examine the processed tissue section and determine the pathological 
response.
Participants who have partial or no-response will be offered standard therapy, at the discretion of 
the treating physician.
We hypothesize that non-responders or partial responders in the PDT arm are likely to be 
participants whose tumor does not retain HPPH. For this subset of participants that are treated with 
PDT at RPCI, an additional biopsy (50 mg tissue mass) will be taken at the time of excision of the 
recurred tumor to evaluate cellular mechanisms that contribute to tumor retention of HPPH. The 
biopsy sample is immediately dropped into a sterile 15-ml screw-cap tissue culture tube containing 
5 ml of serum-free RPMI medium. A set of such tubes are prepared prior to surgery and can be 
stored at 4°C for up to a month until use. A research nurse (or other personnel in the operating 
room, OR) will label the sample tube with an identifier code pertaining to the case, but without 
inclusion of any PHI. The tube containing the biopsy sample will be placed either into a 
refrigerator or bucket of ice until pick-up by a member of the investigating laboratories (Drs. 
Shafirstein or Baumann, as detailed below). The OR personnel will inform the research associate 
in the laboratories of either Dr. Shafirstein or Dr. Baumann via telephone or text message. The

associate will pick-up the sample tube at the entrance to the OR and immediately carry it to the 
laboratory of Dr. Baumann, or Dr. Shafirstein. 
The analysis will be performed in vitro by generating primary tumor cell culture from the biopsy 
material. The tumor cells will be incubated with HPPH and uptake and retention monitored over 
72 hours in the live cultures by microscopic imaging. HPPH fluorescence will serve as indicator 
for subcellular location and concentration of HPPH.

PARTICIPANT QUALITY OF LIFE EVALUATION
Participants’ QoL will be evaluated with the widely accepted University of Washington Quality 
of Life Questionnaire Version 4 (UW-QoLQ v4).49,50 It has been tested in several prospective 
studies and found to be reproducible, reliable, and valid for head and neck cancer patients.51 It is 
simple to complete, employs a simple algorithm to compute the overall score, and is easy to 
interpret while yielding objective results.51 This version includes 12 individual Likert-scale items 
and 4 global questions. Each participant’s overall score on the UW-QoLQ v4 will be calculated at 
baseline, at 12-16 weeks, and at 6, 12, 18, and 24 months post-PDT.
4.3
 MANAGEMENT OF THE NECK AND SALVAGE SURGERY 
The management of the neck will be according to standard of care, at the discretion of the treating 
surgeon. If the participant, based on the pathology of the neck dissection or primary oral cancer 
resection, has perineural invasion, extracapsular spread, or requires additional therapies including 
radiation or chemotherapy, they will be dropped from the study and replaced with another 
participant.
Participants will receive standard curative therapy 6 weeks after failing to respond to PDT with 
HPPH. All the participants who will have disease progression, local recurrence, or partial or no 
response (PR, NR) following the PDT with HPPH will be considered treatment failures. The 
determination will be performed during the study visits, and based on clinical exam and 
pathology, if clinical exam is unclear.
The surgeon will provide a surgical plan for every patient, including those randomized to PDT.  If 
the patient requires salvage surgery post-PDT, the surgeon will compare the salvage surgery 
specimen diameter to the diameter of the spot size used for PDT.  This data will be used to 
demonstrate whether PDT affects the surgical plan.

HANDLING AND DISPOSAL
The manufacturer (Photolitic) will send the investigational drug to the RPCI research pharmacy 
and participating sites. Study drugs must be handled as cytotoxic agents and appropriate 
precautions taken per the institution’s environmentally safe handling procedures. All 
investigational drugs will be dispensed in accordance with the Investigator’s prescription or 
written order.
All products dispensed will be recorded on a product accountability record. Records of product lot 
numbers and dates received will be entered on a product accountability form. This record may be 
reviewed by the Sponsor’s staff or representative. It is the Investigator’s responsibility to ensure 
that an accurate record of investigational drug issued and returned is maintained.
Used vials (excess drug) will be destroyed according to standard practices at the site after properly 
accounting for the dispensing. Partially used vials of study drug will not be re-used for other 
participants.
Under no circumstances will the Investigator supply investigational drug to a third party or allow 
the investigational drug to be used in a manner other than as directed by this protocol.
6.5
THE TREATMENT LASER SYSTEM 
In this study we will use a Modulight laser (ML7710-665). This is a medical laser designed for 
PDT. This laser system can deliver the light fluence rate (W/cm2) and dose (J/cm2) at the 
wavelength (665 ± 3 nm) required to activate the HPPH. The laser system includes a calibration 
port, and a SanDisk memory card for storing device history data. The PDT center at RPCI 
purchased this laser model for research evaluation. 
The participating sites will use the same laser model and identical treatment fibers.
7
TREATMENT PLAN FOR PDT WITH HPPH:
7.1
DOSING AND ADMINISTRATION
For participants randomized to HPPH with PDT, the light and drug dose will be fixed, 150 
mW/cm2 to deliver 140 J/cm2 of 665-nm light and 4 mg/m2 drug, respectively. The HPPH product 
will be added to 100 cc intra venous (i.v.) bag of D5W and infused via i.v. pump over 1 hr.
The justifications for selecting these doses are provided in sections 1.4.1 and 1.5.1. Treatment will 
be administered in an outpatient basis in most cases. Reported adverse events (AEs) and potential 
risks are described in Section 10.1.
7.2
PARTICIPANT DOSE MODIFICATIONS
The drug dose and light dose will not be modified.
7.3
DURATION OF TREATMENT
Participants may remain on study in the absence of disease progression, unacceptable toxicity or 
withdrawal from study.

STUDY WITHDRAWAL
Upon participant withdrawal from the study, all end of study evaluations and tests will be 
conducted. All participants who discontinue due to an AE must be followed until the event resolves 
or stabilizes. Appropriate medical care should be provided until signs and symptoms have abated, 
stabilized, or until abnormal laboratory findings have returned to acceptable or pre-study limits. 
The final status of the AE will be reported in the participant’s medical records and the appropriate 
eCRF.
Reasons for study withdrawal should be classified as follows:

Death.

Progressive disease.

Treatment-related toxicity.

Toxicity unrelated to treatment.

Investigator judgment.

The Investigator may withdraw a participant if, in his/her judgment, it is in the participant’s 
best interest to do so.

Participant receives an additional adjuvant therapy.

Noncompliance

Participant voluntary withdrawal

A participant may withdraw from the study at any time, for any reason. If a participant 
discontinues treatment, an attempt should be made to obtain information regarding the 
reason for withdrawal.

Participants in which the surgical pathology demonstrates perineural invasion, 
extracapsular spread or the participant requires additional therapy including radiation or 
chemotherapy.
Participants who are unavailable for follow-up evaluations should be classified as lost to follow-
up for 1 of the following reasons:

Lost to follow-up: For a participant to be considered lost to follow-up, the investigator must 
make two attempts to re-establish contact with the participant. The attempts to re-establish 
participant contact must be documented (e.g., certified letter).

Death: Date and cause of death will be recorded for those participants who die within 
30 days after last dose of study drug (telephone contact with family is acceptable).

PARTICIPANT RANDOMIZATION AND REGISTRATION
We will employ a web-based stratified blocked randomization scheme developed at RPCI by the 
biostatistician in conjunction with the GOG Foundation Statistical & Data Management Center. 
Participants will be randomized stratified by study site with permuted blocks of size 4 within strata 
and will assigned to standard of care surgery or PDT with HPPH. Study sites will need to have 
IRB approval entered into the system prior to accessing the randomization system. Eligibility of 
each participant will be established prior to randomization.
Informed consent MUST be completed prior to receiving any study related procedures.

8.10 CORRELATIVE STUDIES SAMPLE COLLECTION AND PROCESSING
8.10.1 Immune Monitoring for Isolation and Storage of Immune Cells
This assay will be performed only for participants randomized to PDT with HPPH. Whole blood 
samples for immune monitoring for isolation and storage of immune cells will be collected via 
venipuncture using (1) 10 mL green-top heparinized collection tube. If possible, sample collection 
will be obtained at the following time points:

Prior to infusion of HPPH on Day 0

About 1 week after the infusion of HPPH

About 4 – 6 weeks after the infusion of HPPH
Whole blood samples collected at RPCI will be sent at room temperature for processing the same 
day of collection.
Whole blood samples collected at participating sites will be shipped at room temperature on the 
day of collection Monday - Thursday. Do not ship specimens on Fridays or on day before a 
holiday.  Samples should be clearly labelled with study #, patient initials, subject ID #, date of 
collection, source of material, (i.e. blood, serum) and sample time point (i.e. prior to infusion of 
HPPH, Day 0), Each subject should have their samples entered on a Network Specimen Requistion 
Form (Other) provided for you along with e-mail notification to Dr. Gollnick; 
Sandra.Gollnick@RoswellPark.org and crsnetworkcoordinators@roswellpark.org

8.10.2 Photosensitizer (HPPH) and Biomarker (Serum Alkaline DNase) Levels in Serum
This assay will be performed only for participants randomized to PDT with HPPH. Blood for 
determination of photosensitizer and biomarker levels will be collected via venipuncture using (1) 
10 mL red-top collection tube. Whole blood should be allowed to clot and serum isolated via 
centrifugation. Caution should be used to prevent hemolysis. Sample collection will be obtained 
at the following time points:

Prior to infusion of HPPH on Day 0

About 1 week after the infusion of HPPH

About 4 – 6 weeks after the infusion of HPPH
Whole blood samples collected at RPCI will be picked up at room temperature for processing in 
Dr. Bellnier’s laboratory the same day of collection.
Serum will be isolated per network site’s SOP specific to their centrifuge. Isolated serum samples 
from participating sites will be frozen at site (-80C) and stored at site until notified by Network 
coordinator to batch ship all three-time points for each subject. Each patient will have a Network 
Specimen Requisition Form (Other) filled out and included in the shipment. Ship only on Monday-
Thursday. Do not ship specimens on Fridays or on day before a holiday. Samples should be clearly 
labelled with study #, patient initials, subject ID #, date of collection, source of material, (i.e. blood, 
serum) and sample time point (i.e. prior to infusion of HPPH, Day 0), with e-mail notification:

8.10.3 Diffuse reflectance optical spectroscopy
This assay will be performed only for participants randomized to PDT with HPPH. Non-invasive 
reflectance spectroscopy will be performed to assess HPPH concentration, blood volume, and 
blood SO2 within the lesion before and immediately after PDT. We will use the reflectance system 
marketed by Zenalux (Zenascope). This device has been approved by the IRB at RPCI for use in 
two ongoing clinical studies (I 235613 and I 239713). A short description of the system and the 
scientific rationale are provided in Appendix B.

The measurements will be done by placing the measurement probe (5 mm in diameter) in contact 
with the surface of the lesion for a few seconds. The probe will deliver low-intensity white light 
to the lesion and detect the reflected light. A total of 3-5 measurements will be taken from the 
center of each lesion, before and immediately after PDT. The data set will be identified by the 
participant’s ID and stored on a secure laptop. The end of the probe will be disinfected after use in 
each participant by soaking it in Cidex for 15 minutes following the procedure described in 
Appendix C.
8.11 PATHOLOGY
At each site, the tumor biopsy will be sent to a surgical pathologist and processed for routine 
standard of care pathological examination. When tumor-biopsy morphology precludes objective 
evaluation by histopathology, ancillary immunohistochemical studies may be employed to 
determine the presence of tumor cells, by the pathologist. (If standard H&E cannot be used to 
evaluate the presence of tumor cells, the pathologist will use immunohistochemistry to evaluate 
the biopsy).

EFFICACY EVALUATIONS
9.1
OBJECTIVE TUMOR RESPONSE
Pathological tumor response will be evaluated by taking a 3-mm punch biopsy from the PDT 
treated or surgical area at 12-16 weeks after PDT or surgery. The participants from the PDT and 
surgery arms will be followed clinically up to 2 years. At the end of the follow up time, the treating 
physician will examine the clinical response and a photograph of the treatment site will be taken 
with paper ruler, to determine the reduction in the lesion size, according to RECIST v1.1. The 
study coordinator or nurse will take the photos. The treating physician will determine the lesion 
size with a caliper if photos can't be taken.
9.2
TARGET LESIONS
All identifiable lesions will be recorded with digital photography and clinical examination. The 
objective tumor response will be determined according to the following criteria per Recist v1.1:

Complete Response (CR): Disappearance of all target lesions. Any lymph nodes must 
have a reduction in short axis to < 10 mm.

Page 36 of 64

Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, 
taking as reference the baseline sum diameters. A biopsy will be taken from the suspected 
lesions for histological confirmation of squamous cell carcinoma.

Progressive Disease (PD): At least a 20% increase in the sum of diameters of target 
lesions, taking as references the smallest sum on study (this includes the baseline sum if 
that is the smallest on study). In addition to the relative increase of 20%, the sum must also 
demonstrate an absolute increase of at least 5 mm. The appearance of one or more new 
lesions is also considered progression.

Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase 
to qualify for PD, taking as reference the smallest sum diameters while on study, the 
response will be listed with stable disease. In this case, a biopsy will be taken from the 
suspected lesion for histological confirmation.
9.3
EVALUATION OF RESPONSE
Time point response assessments will be performed 12 - 16 weeks and 24 months after PDT. To 
determine time point response, refer to Table 4 below.

The best overall response is the best response recorded from the start of study treatment until 
follow-up is completed or the participant goes off study (the end of treatment taking into account 
any requirement for confirmation).

Symptomatic Deterioration: Participants with global deterioration of health status requiring 
study withdrawal without objective evidence of disease progression at that time, and not related 
to study treatment or other medical conditions should be reported as progressive disease due 
to “symptomatic deterioration.” Every effort should be made to document objective 
progression even after discontinuation of treatment due to symptomatic deterioration. 
Symptomatic deterioration that may lead to study withdrawal includes, but is not limited to, 
symptoms such as:
o
Weight loss > 10% of body weight.

10 SAFETY EVALUATION
10.1 ADVERSE EVENTS
10.1.1 Definition
An adverse event or adverse experience (AE) is any untoward medical occurrence associated with 
the use of a drug in humans, whether or not considered drug related. Therefore, an AE can be ANY 
unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease 
temporally associated with the use of a medicinal (investigational) product, whether or not 
considered related to the medicinal (investigational) product (attribution of ‘unrelated’, ‘unlikely’, 
‘possible’, ‘probable’, or ‘definite’).
An AE is considered “unexpected” if it is not listed in the investigator brochure or is not listed at 
the specificity or severity that has been observed; or if an investigator brochure is not required or 
available, is not consistent with the risk information described in the general investigational plan 
in other study-related documents.
10.1.1.1 Diagnosis Versus Signs and Symptoms
If known, a diagnosis should be recorded on the CRF rather than individual signs and symptoms 
(e.g., record only liver failure or hepatitis rather than jaundice, asterixis, and elevated 
transaminases). However, if a constellation of signs and/or symptoms cannot be clinically 
characterized as a single diagnosis or syndrome at the time of reporting, each individual event 
should be recorded as an AE or SAE on the CRF. If a diagnosis is subsequently established, it 
should be reported as follow-up information.
10.1.1.2 Adverse Events Occurring Secondary to Other Events
In general, AEs occurring secondary to other events (e.g., cascade events or clinical sequelae) 
should be identified by their primary cause. For example, if severe diarrhea is known to have 
resulted in dehydration, it is sufficient to record only diarrhea as an AE or SAE on the CRF.
However, medically significant AEs occurring secondary to an initiating event that are separated 
in time should be recorded as independent events on the CRF. For example, if a severe 
gastrointestinal hemorrhage leads to renal failure, both events should be recorded separately on 
the CRF.
10.1.1.3 Abnormal Laboratory Values
Only clinically significant laboratory abnormalities that require active management will be 
recorded as AEs or SAEs on the CRF (e.g., abnormalities that require study drug dose 
modification, discontinuation of study treatment, more frequent follow-up assessments, further 
diagnostic investigation, etc.).

If the clinically significant laboratory abnormality is a sign of a disease or syndrome (e.g., alkaline 
phosphatase and bilirubin 5 x the upper limit of normal associated with cholecystitis), only the 
diagnosis (e.g., cholecystitis) needs to be recorded on the Adverse Event CRF.
If the clinically significant laboratory abnormality is not a sign of a disease or syndrome, the 
abnormality itself should be recorded as an AE or SAE on the CRF. If the laboratory abnormality 
can be characterized by a precise clinical term, the clinical term should be recorded as the AE or 
SAE. For example, an elevated serum potassium level of 7 mEq/L should be recorded as 
“hyperkalemia”.
Observations of the same clinically significant laboratory abnormality from visit to visit should 
not be repeatedly recorded as AEs or SAEs on the CRF, unless their severity, seriousness, or 
etiology changes.
10.1.1.4 Preexisting Medical Conditions (Baseline Conditions)
A preexisting medical condition should be recorded as an AE or SAE only if the frequency, 
severity, or character of the condition worsens during the study. When recording such events on 
an Adverse Event CRF, it is important to convey the concept that the preexisting condition has 
changed by including applicable descriptors (e.g., “more frequent headaches”).
10.1.2 Grading and Relationship to Drug
The descriptions and grading scales found in the CTEP Version 4 of the NCI Common 
Terminology Criteria for Adverse Events (CTCAE) will be utilized for AE reporting. CTEP 
Version 4 of the CTCAE is identified and located at:
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm.
AEs not covered by specific terminology listed should be reported with common medical 
terminology and graded according to definitions provided in the CTCAE Version 4.
The relationship of event to study drug will be documented by the Investigator as follows:

Unrelated: The event is clearly related to other factors such as the participant’s clinical state, 
other therapeutic interventions or concomitant drugs administered to the participant.

Unlikely: The event is doubtfully related to investigational agent(s). The event was most likely 
related to other factors such as the participant’s clinical state, other therapeutic interventions, 
or concomitant drugs.

Possible: The event follows a reasonable temporal sequence from the time of drug 
administration, but could have been produced by other factors such as the participant’s clinical 
state, other therapeutic interventions or concomitant drugs.

Probable: The event follows a reasonable temporal sequence from the time of drug 
administration, and follows a known response pattern to the study drug. The event cannot be 
reasonably explained by other factors such as the participant’s clinical state, therapeutic 
interventions or concomitant drugs.

12 STATISTICAL METHODOLOGY
The primary objective of this study is test the non-inferiority of PDT to standard of care by 
comparing the rate of tumor response after PDT to those obtained after surgery, at 24 months post 
treatment. The secondary objectives are to compare QoL after PDT or surgery at 6, 12, 18, and 24 
months post-procedure, and to assess the toxicity using the CTEP NCI Common Terminology 
Criteria for Adverse Events (CTCAE Version 4.0).

12.1 JUSTIFICATION FOR THE STATISTICAL DESIGN AND THE NON-
INFERIORITY MARGIN 
In our previously published study we observed an 82% CR in patients with T1/T2 N0 SCC of the 
oral cavity treated with PDT and HPPH.18 We also reported a similar response rate when we used 
HPP-PDT to treat early stage laryngeal cancer.52 These response rates are in agreement with other 
studies using PDT in this indication (see Table 1 in section 1.3). All patients that failed to respond 
were successfully salvaged by surgery. Since the local recurrence rate after initial surgery is as 
high as 20%,7-9 we believe that it is reasonable to assume that 85% CR will be observed in both 
arms. We also wish to provide a bit of a cushion in case the surgical response rate is much higher 
than 85% given we are in an experimental setting.
In addition, we propose using the logic and rational the FDA guidance documents propose for 
traditional phase III bioequivalence trials in terms of our trial design. The FDA refers to various 
rules such as the 80/20 rule, 75/75 rule, where the generic drug needs to be within 20% of the 
brand product relative to specified pharmaceutical measures. For a phase III trial the standard 
80/20 rule translates to approximately a 17 percentage point difference. The 75/75 rule yields 
roughly a 21 percentage point difference. Hence, in the phase II setting we believe a 20-point 
difference is reasonable in terms of determining whether or not a confirmatory large-scale phase 
III trial with a tighter equivalence window should be put forward as a next step. The information 
gained form this study will be used for a larger scale phase III equivalence trial in terms of planning 
and sample size calculations with a tighter equivalence threshold. In terms of safety, it should be 
noted that patients that fail PDT can be effectively salvaged with surgery, in a timely manner.    
12.2 SAMPLE SIZE DETERMINATION
In the proposed randomized trial, participants will be randomized to the treatment arms using a 
stratified block randomization scheme, with blocking stratified by clinical site (RPCI, and two 
other participating sites). Participants will be included in data analyses according to their 
randomized treatment assignment irrespective of the treatment actually received (intent-to-treat). 
Exceptions would include those who withdraw their consent to use any of their data prior to 
receiving any study medication. Initiation of study treatment will take place as soon as possible 
following randomization. No method of imputation will be used for missing data. All available 
data from participants who fail to complete this study will be included in all safety summaries.
The safety of the interventions will be assessed through the evaluation of Grade 3 or higher 
toxicities deemed possibly related to treatment. Both efficacy (e.g., tumor response) and toxicity 
rates will be estimated using simple relative frequencies. The corresponding 95% confidence 
intervals for the estimated probabilities will be computed using the method proposed in Clopper 
and Pearson (1934).
The design for this study is based on a test for non-inferiority of PDT compared to standard of care 
with regards to tumor response at 24 months post-procedure. Justification for use of a non-
inferiority trial is that PDT may be viewed as a potential replacement for standard of care if it is 
established as less toxic than the standard of care yet still providing acceptable efficacy. Let

) is the probability of observing a particular set of 
results. A non-inferiority margin of 20 percentage points will be utilized and the Farrington-
Manning based test will be performed in conjunction with a 0.05 nominal significance level. In 
the event that the non-inferiority test is statistically significant, a test for superiority will be 
conducted. The samples sizes of the trial are set at 57 in the standard of care and PDT groups. With 
the proposed sample sizes, there is approximately 80% power associated with the non-inferiority 
test when the true tumor response probabilities are equal to 85% in both groups. The calculation 
was carried forth using SAS PROC POWER.
In the analysis of QoL simple data analyses will initially take place including individual 
participant-level profile plots and overall mean plots used to examining the mean structure. 
Formal statistical examination of longitudinal patterns will be done through the use of a mixed 
model. Restricted maximum likelihood estimation will be utilized in the model fitting procedures 
as implemented by SAS PROC MIXED (version 9.3). Once the model is fit, specific linear 
contrasts based on the estimated model parameters will be constructed and used to test 
hypotheses concerning between time points and between group comparisons. We acknowledge 
the possibility of informative missingness, that is, the probability of a particular observation 
being missing may be related to the health of the participant, and therefore analyses will be 
interpreted with caution. All tests will be two-sided and tested at a 0.05 nominal significance 
level. Standard diagnostic plots will be used to assess model fit and transformations of variables 
may be considered in order to meet statistical assumptions.
12.3 EFFICACY ANALYSIS
Objective tumor response will be tabulated overall. All participants who will be randomized to the 
PDT treatment or surgery will be evaluable for response. Tumor response will be evaluated 
according to RECIST v1.1. The treating physician will examine the clinical response and a 
photograph of the treatment site/s will be taken with paper ruler, to determine the reduction in the 
lesion size. Tumor response will be determined according to the guidelines in sections 9.2 and 9.3. 
If clinically indicated, the clinical evaluation will be confirmed with pathological examination of 
tissue 3-mm punch biopsy that will be taken from the treated region.
12.4 ADVERSE EVENT
The frequency of toxicities will be tabulated by grade. All participants who receive any study 
treatment will be considered evaluable for toxicity.

Appendix B. Spectroscopy
In participants where the lesion location permits use of a non-invasive spectroscopy probe, 
quantitative diffuse reflectance spectroscopy measurements will be performed immediately prior 
to and immediately following PDT. The information extracted from these measurements includes 
hemoglobin oxygen saturation (SO2), blood volume, and HPPH concentration.
Intriguing preliminary associations have emerged between several of these metrics and treatment 
response, but the small number of treatment failures precludes any firm conclusions based on our 
previously published Phase I results (Rigual, Shafirstein et al. Clinical Cancer Res 2013). In 
keeping with our central focus of establishing PDT as a mainstream option for head and neck 
cancer, the spectroscopy device to be deployed to sites outside of Roswell Park will be the 
reflectance system marketed by Zenalux Biomedical, Inc. This system is inexpensive, compact, 
and has been rigorously characterized by our collaborators at the University of Rochester (Drs. 
Foster and Baran). The Zenalux system is available widely to clinicians. It is fully capable of 
acquiring the reflectance data necessary to test the hypotheses that one of a combination of initial 
HPPH levels, blood volume, and hemoglobin oxygen saturation are useful predictors of tumor 
response to HPPH PDT.
Each of the above-mentioned parameters offers the potential to report something important about 
a tumor’s amenability to PDT and/or its response to a treatment. For example, because the 
photochemistry of PDT relies on oxygen, one would predict that relatively high SO2 at the time of 
treatment would predict for a good response. Similarly, a higher photosensitizer concentration 
would be an indicator that likely predicts for a favorable response. Therapy-induced reductions in 
tumor blood volume and the details of the time course of blood volume reduction have been useful 
reporters in pre-clinical models. This creates a significant clinical research opportunity to identify 
readily accessible, non-invasive surrogate optical reporters of treatment response, which may 
eventually help to identify which participants may require follow-up PDT or some other 
intervention following an initial treatment. Thus, there is a strong scientific rationale for the use of 
these forms of optical spectroscopy studies.

Appendix G. Correlative Studies (if possible)
Examination of Induction of Anti-Tumor Immunity in Participants Treated with PDT
In order to determine whether PDT enhances anti-tumor immunity a three-pronged analysis will 
be performed. The effect of PDT on T cell activity will be initially be determined by examining 
the activation status of participant T cells before and after PDT administration. PDT induces a 
rapid pro-inflammatory response; such responses are associated with T cell activation and 
proliferation, which are frequently muted in participants with advanced cancer. T cell activation 
will be determined by flow cytometric analysis of peripheral blood T cells. Using T cell subtype 
and activation specific profiles, this analysis will allow us to determine whether administration of 
PDT alters both the activation status and ratio of T Cell subtypes present before and after therapy.
The phenotypic characterization described above will determine whether PDT affects T cell 
activation and subtype ratio but will not discern whether the effects are tumor specific. Most 
tumors over-express p53 and many head and neck tumors overexpress HPV 16. Examination of 
changes in the immune response to p53 and/or hpv 16 can reveal changes in tumor specific immune 
responses. To examine whether PDT enhances the immune response to p53 or HPV 16, peripheral 
blood T cells will be isolated and exposed to p53 and HPV 16 ex vivo. The ability of each 
participant’s T cells to respond will be measured over time and compared against pre-treatment 
results and to their ability to respond to antigens they have previously been exposed to, 
i.e., cytomegalovirus, Epstein-Barr virus and influenza virus (the so-called memory mix).
The second method for examining tumor specific T cells following PDT involves adding an 
additional marker to the flow panels described above. There is a well-defined p53 immune epitope 
that binds to the human major histocompatibility complex molecule HLAA2. Greater than 40% of 
the patients at RPCI express HLA-A2. HLA-A2 expression status of the trial participants will be 
determined. T cells isolated from HLA-A2+ participants will be tested for p53 reactivity using a 
flow cytometry reagent known as a tetramer that allows identification of p53 specific T cells.
The methods described above will determine whether PDT enhances T cell responses. To 
determine whether there is an increase in humoral (B cell) responses to tumors following 
administration of PDT changes in the levels of circulating antibodies against p53 and HPV 16 will 
be 
measured.
