Brief Summary:
This study evaluates the combination of BYL719, cisplatin and cetuximab as induction chemotherapy prior to minimally-invasive transoral surgery (TORS or TLM) and selective lymph node dissection (SLND), followed by risk-adapted intensity-modulated radiation therapy (IMRT) in patients with transorally resectable, Stage III-IVa, HPV-associated oropharyngeal squamous cell carcinoma (OPSCC).

Detailed Description:

HPV status and tobacco use are the major independent prognostic factors for patients with OPSCC. Patients with HPV-associated OPSCC have a favorable prognosis when treated with chemotherapy, radiation, and/or surgery. This has resulted in national trials investigating de-intensification strategies for good-risk patients with HPV-associated OPSCC, where current multimodality paradigms may represent overtreatment.

The PI3K/Akt/mTOR signaling network, a mitogenic pathway regulating cellular metabolism, proliferation and survival, plays a major role in HPV biology. Starting with early infection, activation of PI3K suppresses autophagy and induces functional protein translational machinery. Activation of the pathway is a nearly universal aspect of mammalian viral infection, and is of particular importance for dsDNA viruses such as HPV. The oncoproteins E5, E6 and E7 also have direct roles in pathway activation. Moreover, HPV-associated OPSCC demonstrates a strikingly high prevalence of genomic activation of the PI3K pathway, including activating PIK3CA mutations (27-31%), PIK3CA amplification (20%), and loss of PTEN (30%), the negative regulator of PI3K. Overall genomic events hypothesized to result in PI3K pathway activation are present in approximately 45-60% of HPV-transformed OPSCC.

BYL719 is an oral, small molecule, alpha-specific inhibitor of PI3-Kinase. Because HPV-associated OPSCC demonstrates a high rate of both genomic and non-genomic PI3K pathway activation, we hypothesize that adding BYL719 to platinum-taxane induction chemotherapy in HPV-associated OPSCC will increase clinico-radiologic complete response relative to historical control. In this phase I/II trial, eligible patients wiht HPV-associated OPSCC will be treated with 3 cycles of induction BYL719, cisplatin and paclitaxel. Induction will be followed by minimally-invasive, transoral surgery (TORS or TLM) then risk-adapted IMRT.

    • Sexually active males should use a condom during intercourse while taking drug and for 12 weeks after completion of all protocol treatment and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid, during the period of BYL719 treatment (induction chemotherapy) and for 4 weeks following completion of BYL719.
    • Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and 12 weeks after completion of all study treatment. Highly effective contraception methods include:

      • Total abstinence (when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
      • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment

    • Note: hormonal contraception methods (e.g. oral, injected, and implanted) are not allowed as BYL719 may decrease the effectiveness of hormonal contraceptives
    • Note: Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago.
