  • Agenda

    • Introductions and background

    • Answering the scientific questions – Mechanism of action – General acceptance by medical community – Net positive health outcomes – Predictors of success – Additional supporting evidence

    • Patient perspective

    2

  • Participants

    • Bill Doyle – Executive Chairman, Novocure

    • Matthew Ballo, M.D. – Professor of Radiation Oncology, University of Tennessee Health Science Center – Medical Director, Radiation Oncology, West Cancer Center

    • Steve W. – Tumor Treating Fields patient

    • Adrian Kinzel, M.D. – Vice President and Medical Director, Novocure

    3

  • Definitions and abbreviations

    • Tumor Treating Fields – common scientific name in the literature – TTFields – TTF – TTFields treatment or TTF treatment

    • Tumor Treatment Field Therapy (TTFT) – Medicare/MAC name for the therapy

    • Optune® – Brand name for the TTFields delivery device for glioblastoma patients – Formerly known as the NovoTTF-100A™ device

    • EF-14 Trial – Randomized control trial (n=695) for TTFields in newly diagnosed glioblastoma

    • Glioblastoma – GBM – Glioblastoma multiforme, older name based on a previous WHO classification

    4

  • Requested coverage for Tumor Treating Fields

    • Medicare coverage requested:

    “TTFT with temozolomide (TMZ) is covered for the treatment of adult patients with newly diagnosed, supratentorial glioblastoma following maximal debulking surgery and completion of radiation therapy together with concomitant standard of care chemotherapy.”

    • Requested coverage matches the FDA pre-market approval (PMA) indication for use:

    “Optune® with temozolomide is indicated for the treatment of adult patients with newly diagnosed, supratentorial glioblastoma following maximal debulking surgery and completion of radiation therapy together with concomitant standard of care chemotherapy.”

    5

  • FDA premarket approval (PMA) background

    • “PMA is the most stringent type of device marketing application required by FDA.”

    • “Class III devices are those that support or sustain human life, are of substantial importance in preventing impairment of human health, or which present a potential, unreasonable risk of illness or injury.”

    • “PMA approval is based on a determination by FDA that the PMA contains sufficient valid scientific evidence to assure that the device is safe and effective for its intended use(s).”

    U.S. Food and Drug Administration (FDA). Premarket Approval (PMA) webpage. Accessed March 2, 2019. https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/HowtoMarketYourDevice/PremarketSubmissions/PremarketApprovalPMA/default.htm

  • Medicare standards for local coverage determinations (LCD)

    Medicare Program Integrity Manual, Chapter 13, section 13.5.3. Rev 863, 02-12-19. Accessed March 2, 2019.

    7

    • General acceptance standard for LCDs

    “In conducting a review, MACs [Medicare Administrative Contractors] shall use the available evidence of general acceptance by the medical community, such as published original research in peer-reviewed medical journals, systematic reviews and meta-analyses, evidence-based consensus statements and clinical guidelines.”

  • Agenda

    • Introductions and background

    • Answering the scientific questions – Mechanism of action – General acceptance by medical community – Net positive health outcomes – Predictors of success – Additional supporting evidence

    • Patient perspective

    8

  • How confident are you that scientific evidence supports mitotic spindle disruption and cellular apoptosis as the mechanism of action of TTFT?

    9

  • Substantial research demonstrates the effects of forces on tubulin proteins and the mitotic spindle

    10

    Biophysics literature reports clear thresholds of force required to halt spindle formation Dogterom M et al. Science. 1997; 278: 856-60

    473 publications in Medline Database on the biophysics of mechanical forces and tubulin function

    1980 “Many models for the mechanism of [microtubules] MT-mediated transport and mitosis postulate an important role for MT polarity because a symmetric fibre could not generate force in one direction along its surface.”

    2018 “Dynamic microtubules can also engage in mechanical processes, such as exerting forces by pushing or pulling against a load…[microtubule-associated proteins] and forces can modulate microtubule growth and shrinkage.”

    Polar (charged) tubulin dimer proteins orient in direction of electric fields

  • Mitotic spindle disruption by electric fields has been observed in every cancer cell line tested

    Mitotic spindle disruption in fluorescence images of A549 cells exposed to TTFields

    A549 cells in lung tissue were treated with Tumor Treating Fields for 24  hours. Tubulin fluorescence images were inverted and pseudocolored so that increasing fluorescence intensity is indicated from blue to red (scale bar represent arbitrary units). Dashed lines define the region between the two spindle poles (white) and overall tubulin fluorescence within the cell (Red). 1. Giladi M., et al. Sci Rep. 2015 Dec 11;5:18046. 2. Kim EH, et al.

  • Independent research confirms TTFields system delivers effective electric field dose to cranium

    Electric field intensity (V/cm) models confirm dose deposition in target regions

    Electric field distribution within the brain was calculated using the finite element method to solve the quasistatic approximation of the Maxwell’s equations. The model estimates field distribution with consideration for established measurements of permitivity (σ) and conductivity (εr) for critical tissue (e.g., skull, white matter, tumor, etc.).1.

    Medicare’s current negative LCD is:

    • Non-conforming with U.S. payers

    • Out of step with reimbursement decisions by other major governments around the world

  • Personalizing the array layout: changing the layout changes field distribution and resulting dose delivered to tumor

    • Field strength within a tumor did not correlate with its size and shape

    • Field strength always increased when the arrays were adapted to the tumor's location

    – Compared with a default layout, the largest increase in field strength was 184%

    – The highest average field strength induced in a tumor was 2.21 V/cm

    A numerical simulation-based analysis of patient data from the EF-14 randomized trial

    1West Cancer Center Center, Memphis Tennessee; 2Novocure Ltd, Haifa, Israel; 3Warren Alpert Medical School of Brown University

  • Background

    Rationale: • Preclinical investigations have defined a relationship between TTFields

    antimitotic effects and exposure time (in hours), frequency (in kHz) and field intensity (in V/cm).

    • The randomized clinical phase III trial (EF-14) of TTFields in Glioblastoma showed improved overall survival.

    • The overall survival benefit was associated with the degree of TTFields compliance (% monthly use).

    Hypothesis: • Overall survival and Progression free survival are higher in patients who

    receive higher doses of TTFields at the tumor bed.

  • Methods: Step 1: Contouring of tumor on MRI Step 2: Head model creation & Transducer placement

    Step 3: Intensity Distribution calculation • Assign electric properties to model tissue types • Calculate 3D electric field distribution numerically (Finite Difference Method). • Analyze Field distribution by gross tumor volumes & peritumoral boundary zones (3mm around GTV and Resection cavity)

    Patient data EF-14 TTFields txt arm: N=466 Treatment duration >2 mths: n=379 Sufficient MRI quality: n=340 Total number for analysis: 340 patients

    Local Minimum Field Intensity (LMiFI) : The lower of the two field intensities delivered to each point (Volts/cm) Local Minimum Power Density (LMiPD): The lower of the two power densities delivered to each point (milliWatts/cm3)

  • Higher TTFields intensity (≥1.0 Volts/cm) and power density (≥1.1 mW/cm3) are associated with improved overall survival and independent of compliance

  • Summary:

    • Higher TTFields intensity (≥1.0 Volts/cm) and power density (≥1.1 mW/cm3) are associated with improved overall survival and independent of compliance.

    • Calculating, visualizing and manipulating TTFields dose distributions to maximize TTFields dose in the tumor bed is expected to improve patient outcome further.

    • A new term, Dose Density, expresses the two most important variables associated with TTFields use and Overall Survival as a single variable.
