What is I-SPY and I-SPY Trials?

The I-SPY series of trials are changing the way new treatments are developed for breast cancer, helping make available new, better and more personalized treatments, faster. At the heart of the I-SPY program is the ground-breaking I-SPY 2 platform trial for neoadjuvant treatment of locally advanced breast cancer.

The Clinical Trial, Re-Imagined

The ground-breaking I-SPY 2 trial of neoadjuvant treatment for locally advanced breast cancer established a new benchmark for efficiency of phase II clinical trials. Widely regarded as a pioneer of the ‘platform’ trial, I-SPY 2’s success continues to be a major influence on the development of next-generation trial designs in oncology and beyond.

Efficiency Bred From Innovation

The success of the I-SPY 2 trial is not simply the result of a single innovation in trial design.It is the result of a pain-staking deconstruction and re-engineering of the entire clinical trial enterprise, from protocol development through registration.

Early Endpoint

I-SPY 2’s early surrogate efficacy endpoint (pCR) gets results faster

Adaptive Design

Adaptive randomization makes the most of every patient enrolled

Real-World Control

A common control arm as comparator, with a decade of historical data

Curable Population

A breast cancer population where standard of care has much room to improve

Neoadjuvant Model

Systemic therapy first lets you see how tumors respond to treatment

Multiple Agents

Up to 6 agents can be efficiently, independently evaluated in parallel

Biological Targeting

Randomization targets agents to more responsive molecular subtypes

Master Protocol

Less paperwork means vastly compressed start-up times by 3-4 months

Serial MRI

Optimized imaging protocols quantify tumor response over time

Biomarker Discovery

Integrated platform forcompanion biomarker discovery

Active QC

Enterprise-wide process standardization with frequent re-certification

How I-SPY 2 Works

I-SPY 2 breaks from the traditional randomized clinical trial model, employing an ‘adaptive’ clinical trial model designed to increase trial efficiency by minimizing the number of participants and time required to evaluated an experimental agent.

At consent, a new participant’s breast cancer is classified into one of 6 response predictive molecular subtypes. Then, for each participant in the trial:

1

Randomize to Expt’l or Control Arm

I-SPY 2’s adaptive randomization engine assigns a participant to a study arm; it gives greater weight to arms that have been successful in the participant’s tumor subtype.

5

Update Randomization Probabilities

The participant’s serial MRI measures, RCB scores and tumor subtype are used to update the prior probabilities of the randomization engine — over time this refines the targeting of subsequent participants..

2

Patient Outcome (RCB/pCR)

I-SPY 2’s adaptive randomization engine assigns a participant to a study arm; it gives greater weight to arms that have been successful in the participant’s tumor subtype.

3

Update Predictive Probabilities

Based on the participant’s tumor subtype, outcome (i.e. MRI volume, pCR) and treatment received, the predictive probabilities of the agent in the various subtypes are updated in real time.

4

Apply Termination Rules (Per Arm)

If predictive probabilities for an experimental agent reach a pre-determined level of efficacy in one or more molecular subtypes, it is declared a success (“graduates”). Alternatively, it may be stopped for futility after reaching a maximum number of participants. At any point new agents can enter the trial through a protocol amendment.

Study Schema Before June 2022

I-SPY 2 was one of the first, and is now the longest-running ‘platform’ trial ever. As a platform trial, I-SPY 2 uses a master protocol that provides a regulatory framework to study multiple treatments in the same study. It also allows new agents to enter and leave the study without having to halt enrollment or resubmit the entire clinical trial protocol for regulatory review.

Tracey Heather

Advocate Liaison

As Patient Engagement Lead at Quantum Leap, I manage follow-up data projects for the I-SPY 2 Trial, develop strategies to strengthen patient engagement, and oversee the I-SPY Advocate group. After six successful years raising funds to support Quantum’s mission, I embraced this new role last summer, drawn by the opportunity to make a direct impact on the patients we serve. Each day brings new challenges and insights, and I especially enjoy supporting and collaborating with our inspiring I-SPY Advocates.

Outside of work, I am pursuing a Master of Public Administration with a focus on nonprofit management at SF State. I’m passionate about trail running, skiing, live music, camping, traveling, and collegiate gymnastics—my daughter competes at Oregon State. For the past 5 years, I have volunteered with SF CASA as a mentor to an incredible 18-year-old foster youth whose resilience continually reminds me of life’s true priorities.

Carolyn Clark Beedle

Carolyn Clark Beedle, a 2023 breast cancer survivor, joined the advocate program after successful completion of treatment with the UCSF Breast Oncology Program. Her experience working with a patient advocate during her TNBC treatment led to an understanding that empowering women to advocate for their own health and healthcare will contribute to improved health outcomes and broader access to care. Carolyn began advocating for cancer patients and their families during her treatment, now is a member of the Breast Science Advocacy Core (BSAC) with the UCSF Breast Oncology Program, and currently shares information and research with CFNP associates at La Clinica in the Bay Area to inform and empower their patient population.

Carolyn is continuing her on the ground training as an advocate reviewer with both Quantum Health and BSAC and is enrolled in the Patient Advocacy Training in Health Science course with Stanford Medicine. Her 30+ career in corporate marketing/communications, program development and non-profit leadership augmented by her breast cancer treatment experience serves Carolyn well in representing and communicating the patient voice and perspective.

She received her BA (History/English Lit) and MA (Public History/Research and Record Management) from the University of San Diego, is a proud fifth generation San Franciscan, and active board member with numerous non-profits that support social work and the arts.

Jane is a breast cancer survivor and advocate dedicated to positively impacting the lives of women affected by the disease. Diagnosed with triple negative breast cancer in 2012, she participated in the I-SPY 2 trial at UCSF and has been cancer free for more than ten years.

Her advocacy journey began in 2003 at UCSF as a volunteer with the Patient and Family Cancer Support Center and Decision Support Services and she previously managed the Peer Support program at UCSF. Drawing on her experience in marketing and media strategy, she uses her skills to make a meaningful impact by supporting advocacy and research that improves outcomes for women living with breast cancer.

Jan Tomlinson

In March of 2023 , Jan was diagnosed with a large aggressive triple negative breast cancer and informed that her cancer was the” bad girl” of cancer and offered standard chemotherapy for 24 weeks. Devasted by the diagnosis Jan felt like she had a dire prognosis. After seeking several opinions, she opted to join a Clinical Trial program for her treatment. The trial consisted of significantly less chemotherapy, and monitored closely over a 12-week period, The data predicted a complete pathological response , and she then went immediately to surgery. Pathology reports supported that she had a successful outcome reaching PCR meaning the tumor was gone, and no residual cancer was found in the surrounding tissue or lymph nodes. Jan was thrilled when her surgeon advised her of the results. The experience made Jan want to give back and share information that she received when she was at a critical juncture in her diagnosis. She is so passionate about making sure that everyone knows that the standard of care is one treatment option.

As she says, “ clinical trials have to be on the table” Because she achieved PCR, she expects a great outcome. She wants to share her story and encourage other women to strongly consider and participate in clinical trials. Jan is a UCSF Patient Advocate, involved in several programs they lead. Jan also is a BLACC Cab Member. Jan recently was in Washington DC to participate on a panel on Clinical Trials for ISPY at the National Press Club. UCSF will be hosting the RISE Up For Breast Cancer event where Jan will share her experience with clinical trials.
