Multimodality Therapy With Induction Carboplatin/Nab-Paclitaxel/Durvalumab Followed by Surgical Resection and Risk-adapted Adjuvant Therapy for the Treatment of Locally-Advanced and Surgically Resectable Squamous Cell Carcinoma of the Head and Neck

Participants in this study have a type of cancer called squamous cell carcinoma of the head
and neck (SCCHN). Their SCCHN has spread around the area where the cancer first started. This
is called locally-advanced SCCHN. These participants are eligible for surgery.

Previous research with a similar therapy regimen resulted in high rates of cancer shrinkage,
high rates of avoiding radiation and its side effects, high cure rate and good quality of
life. Radiation can be very toxic. The purpose on this study is to try to avoid radiation. If
the participants are not on this study they would be receiving radiation as it is standard
treatment of their cancer. In the last study with a similar regimen, about a third of cancers
had a pathologic complete response with the first part of the study. This means that the
chemotherapy had killed the cancer. The investigators are trying to improve the regimen
further with a goal of increasing this rate of complete response to the first part of
therapy. The investigators also hope that by improving results in the first part, that more
people will be cured and that long term quality of life (especially speech and swallowing)
will be improved, both compared to standard therapies and to the last study. Doctors do not
know how this therapy will effect the participants. There is no guarantee that this study
will benefit the participants.

The prior study used a combination of chemotherapy consisting of carboplatin, paclitaxel and
a third targeted anti-cancer drug. In this study the investigators are testing the
combination of carboplatin, nano-albumin bound paclitaxel and durvalumab. Nano-albumin bound
paclitaxel has been shown to be more active against other types of squamous cancers than
regular paclitaxel. It is FDA approved for squamous lung cancer, but experimental for head
and neck cancer. Durvalumab is an experimental drug that uses the body's own immune system to
fight the cancer. Doctors hope that combining Durvalumab with 2 chemotherapy drugs will be
effective in treating SCCHN. Durvalumab on its own has been studied in patients with SCCHN
and initial results have shown that some subjects' cancer has responded to it.

The purpose of this study is to test a combination of chemotherapy to hopefully both increase
the number of subjects that respond to therapy while also decreasing the number of side
effects that subjects experience.


Primary Objective:

Estimate the pathologic complete response rate (pCRR) after induction chemotherapy with
carboplatin, nab-paclitaxel, and durvalumab in previously untreated stage III and IV SCCHN
amenable to surgical resection

Secondary Objectives:

- Report the clinical complete response rate (cCRR) and clinical response rate (cRR)
following induction chemotherapy

- Estimate the percent of patients who have a change in estimated risk level. Prior to
induction, this will be assessed clinically (by imagining and physical exam). Post
induction, this will be assessed by surgical pathology report

- Estimate the overall survival (OS) and progression free survival (PFS) associated with 3
part therapy consisting of induction chemotherapy, surgery and risk-adapted use of

- Characterize the toxicity profile associated with both induction therapy and total 3
part therapy consisting of induction chemotherapy, surgery and risk-adapted use of

Translational/Exploratory Objectives:

- Correlative studies will evaluate cellular correlates of response and changes in the
tumor microenvironment across therapy

- Explore correlation between measures of clinical response to induction chemotherapy and
long term outcomes (PFS and OS) and compare them to pathologic measures of response

PROCEDURES This is a single-arm, nonrandomized phase II trial consisting of 3 parts. After
informed consent and screening, pre-induction, risk levels will be assessed clinically, by a
combination of physical exam and imaging.

Part 1: All patients will then receive 6 weeks of induction chemotherapy in Part 1 comprised
of weekly cycles of carboplatin and nab-paclitaxel for 6 cycles in combination with
durvalumab administered once every two weeks for 5 cycles (Day 1 of the weeks 1, 3, 5, 7, and

Part 2: Within a 1-4 the week window post induction, tumor imaging will be followed by
surgical resection.

Part 3: After surgery, patients will be stratified into one of 3 risk categories based on
their disease pathology, assigned a treatment group based on their risk. Low risk patients
with receive durvalumab once every two weeks for 3 cycles, while medium risk or high risks
groups will receive concurrent chemoradiation therapy followed by durvalumab once every two
weeks for 3 cycles.

Follow up After completion of study therapy (which will vary by study arm) patients will be
evaluated every three months during follow up for progression over a period of 18 months.
Each follow up visit will include physical examination, CT or MRI imaging of the neck. Chest
imaging will be obtained (or not) as indicated by standard of care. After the first 18
months, patients will be followed-up per standard of care, with documentation in the case
report form (CRF) limited to progression and survival noted at their standard of care visits.
If a patient should move away or otherwise be lost to in-person follow up but is amenable to
telephone follow up, this will be permitted during the standard of care follow up period.

Inclusion Criteria:

- Previously untreated, histologically proven, surgically resectable primary squamous
cell carinoma of the head and neck, stage III or IV (HPV positive or negative
non-metastatic disease). SCCHN of unknown primary is excluded. SCCHN of the oral
cavity is allowed*. Unambiguously squamous Epstein-Barr virus (EBV)-negative
nasopharynx cancer will be excluded nor will unambiguously squamous cancers of the
skull base that are clearly surgically resectable and clearly squamous. Squamous skin
cancer occurring in the head/neck region will not be eligible nor will EBV+positive
nasopharynx cancer. (*Note: Induction chemotherapy is not considered standard therapy
for SCCHN of the oral cavity and participation on this trial will lead to a delay in
time to definitive, potentially curative therapy i.e., surgery).
