Immunotherapy drugs for breast cancer

JohnSmith
JohnSmith Member Posts: 61

Immuno-Oncology (IO) and Immunotherapy drugs are humanity's best shot at beating cancer.

During the last few years, IO has revealed impressive, durable responses in a variety of tumor types for which conventional therapies historically have had limited success (melanoma, leukemia, lymphoma, lung, liver, bladder, etc).
The power of this approach is highlighted in countless articles (like here and here) as well as a variety of TV broadcasts, including:
1. HBO's Vice TV special: "Killing Cancer", explored a subset of IO called "Virotherapy" and how the following three common viruses are genetically modified to find and kill cancer:
- A re-engineered Measles virus was used to treat patients with Multiple Myeloma.
- A re-engineered Adenovirus (like the common cold) to treat patients with Glioblastoma (GBM) brain tumors.
- A re-engineered HIV virus to treat patients with the blood cancer Leukemia.
2. 60 Minutes TV special: "Killing Cancer" focused on curing GBM by using a re-engineered Polio virus.
3. PBS TV special: "Cancer: The Emperor of All Maladies" tells the complete story of cancer, from its history to current breakthroughs. It's six hours long, broken into three videos, with the last part covering IO.

We've reached an inflection point to change the trajectory of breast cancer treatment.
In late 2015, an unprecedented coalition was formed to accelerate progress in IO.
Called the "Cancer Moon Shot 2020" (#CancerMoonShot), this endeavor will bring patients closer to Immunotherapies and precision medicine, by not only exploiting genetics (DNA), but also epigenetics (gene expression), proteomics (protein expression), metabolomics (cancer metabolism). Here's a couple video's discussing the effort:
4. Cancer MoonShot 2020, explained in very simple terms, here.
5. Cancer MoonShot 2020 Press Conference (Jan 2016), here. Listen to the experts.

If you're smart, you asked the question: how can immunotherapy be harnessed in Breast Cancer?

To answer this, I researched the usual resources and was surprised at the paucity of info.
Breastcancer.org's page, Using the Immune Response to Treat BC is outdated and extremely incomplete.
It only discusses these Monoclonal Antibodies (mAbs) used for HER2+ patients:
Herceptin (trastuzumab), Tykerb (lapatinib), Perjeta (pertuzumab), Kadcyla (Trastuzumab or T-DM1).

The Cancer Research Institute's webpage, "Immunotherapy for Breast Cancer", is the most comprehensive resource for US based research, although it was last updated Sept 2014. [Dr. Leisha Emens of John Hopkins reviewed and updated the webpage in March 2016].
It's written that "breast cancer has historically been considered immunologically silent". This statement may contribute to why breast cancer lags behind when compared to other cancers. This notion that breast cancer, in particular ER+ disease, is "not very immunogenic" is an antiquated view that needs to end.
I understand it's "early days", but the breast cancer industry needs a serious paradigm shift.
Listen to this comment at the 2016 CancerMoonShot press conference here). Priorities should be realigned towards the basic science of IO and then translated into cures that exceed the ~7% that standard therapies offer metastatic patients over 10 years (Source: Weissman, June 2015, ~10:00 minute mark).
As patients / caretakers, we should be discussing Immunotherapies with our doctors, encouraging breast cancer researchers to explore this approach and supporting funding efforts aimed at moving the field forward.

So, in a effort to advocate for this community, I wanted to start this topic and get others to ask these questions:

- What progress is being made in Breast Cancer Immunotherapy?
- Who are the thought leaders and researchers in Breast Cancer Immunotherapy?
- Most importantly, where are the Breast Cancer Immunotherapy clinical trials?

Who else shares this sense of urgency?

    chrissie - it was the GP2 peptide vaccine given with GM-CSF.  This was a two armed trial, and half were given GP2 and half AE37, and some placebo with no vaccine.  The placebo was the GM-CSF, so everybody got something, the GM-CSF is similar to Neulasta/Neupogen so it was potentially immune boosting by itself.  We were sorted into the arms by histological tissue type like for organ transplant compatability, which was independent of any cancer info.

    The following link appears to be the most up to date summary of Immunotherapy for breast cancer.
    It's mostly a lot of big words that probably won't make much sense unless you're doing daily research.
    Someday, I'll edit this post and attempt to match these therapies to the appropriate clinical trials.

    "Will immunotherapy help us cure breast cancer?"

    1. Monoclonal antibodies (mAbs) currently being researched in breast cancer clinical trials include:
    - Avastin (bevacizumab), which targets the tumor growth factor VEGF-A
    - Cyramza (ramucirumab), which targets the tumor growth factor VEGFR-2
    - MGAH22 (margetuximab), which blocks the action of HER2 on tumor growth
    - OMP-18R5 (vantictumab), which targets a tumor growth pathway known as the Wnt beta-catenin signaling pathway
    - LJM716, which blocks a protein called HER3 that enables tumors to become resistant to treatment
    - LY2875358, an anti-MET antibody
    - CDX-011 (glembatumumab vedotin) and IMMU-132, which target cellular proteins that enable tumors to metastasize

    2. Therapeutic cancer vaccines currently being researched in breast cancer clinical trials include:
    - A HER2 peptide vaccine called NeuVax (nelipepimut-S) UPDATE - JUNE 2016: The NeuVax Phase 3 clinical trial (PRESENT) has been stopped (cancelled), due to futility. NeuVax was unable to prevent recurrence in this trial; a HER2-pulsed dendritic cell vaccine; and the peptide vaccines E39 and J65, which are being tested to prevent breast cancer recurrence
    - AVX901, which helps the immune system destroy tumor cells that express HER2
    - INO-1400 (by Inovio Pharmaceuticals), a synthetic DNA vaccine targeting the hTERT antigen.
    hTERT = human telomerase reverse transcriptase [This is being explored for Triple Negative BC]

    3. Checkpoint inhibitors/immune modulators currently being researched in breast cancer clinical trials include:
    - The anti-CTLA-4 antibody Yervoy (ipilimumab)
    - The anti-PD-1 antibodies Keytruda (pembrolizumab, MK-3475) and Opdivo® (nivolumab)
    - The anti-PD-L1 antibodies MPDL3280A and MEDI4736
    - The anti-OX40 antibodies MEDI6469 and MEDI6383

    4. The following types of adoptive T cell transfer are being researched for patients with breast cancer:
    - Tumor infiltrating lymphocytes (TILs) that are removed from a patient's tumor, boosted in the lab, then given back to the patient. This is essentially CAR-T Immunotherapy, which has cured a number of people with hematological malignancies like Leukemia & Lymphoma.
    - T cells genetically engineered to target several cancer-associated antigens, including:
    * HER2
    * cMet protein
    * CEA
    * VEGFR-2
    * MAGE-A3

    5. Cytokines currently being researched in clinical trials of breast cancer include the following interleukins:
    - Interleukin-2, an important growth factor for white blood cells
    - Interleukin-7, an important growth factor for T cells and B cells

    6. Adjuvant immunotherapies currently being researched in breast cancer clinical trials include:
    - Indoximod, an IDO inhibitor, which blocks an immunosuppressive molecule produced by tumor cells
    - Poly-ICLC, a Toll-like receptor (TLR) 3 agonist

    This is an update on the Immunotherpy drug "Keytruda" (AKA: Pembrolizumab, MK-3475).
    Keytruda is a Monoclonal antibody and acts as a checkpoint inhibitor, specifically a PD1 inhibitor. It targets the PD-1 protein on T cells (a kind of immune cell). The drug removes the "brakes" (biological blockades) that keep T cells (also called T lymphocytes) from attacking cancer.
    It's FDA approved for Lung cancer and Melanoma (think former President Jimmy Carter). As a single agent (monotherapy), it's shown to be useful in TNBC trials and has similar potential in ER+ disease, as just reported by Dr. Hope Rugo of UCSF, here, "Pembrolizumab's Potential in ER+ / HER2- patients".

    As of Feb 2016, Keytruda is in at least 20 different clinical trials for breast cancer, listed below (This may not be a complete list and serves as a springboard to get you started. Please do your own due diligence)

    01. metastatic ER+ [NCT02395627] This one deals with Epigenetics, and includes a HDAC inhibitor too!
    02. metastatic ER+, HER2- [NCT02054806] KEYNOTE-28 trial. A basket trial evaluating 20 different types of cancer with PD-L1 expression. Results of the ER+, HER2- are here.
    03. metastatic IBC [NCT02411656]
    04. metastatic TNBC or metastatic ER+, HER2- [NCT02648477]
    05. metastatic TNBC [NCT02513472] KEYNOTE-150 trial
    06. metastatic TNBC [NCT02447003] KEYNOTE-086 trial
    07. metastatic TNBC [NCT02555657] KEYNOTE-119 trial
    08. metastatic HER2+ [NCT02129556] PANACEA trial
    09. metastatic HER2+ [NCT02318901] PembroMab trial
    10. metastatic TNBC & other solid tumors [NCT02646748] This one deals with the Tumor Microenvironment, and includes a JAK inhibitor, and a PI3K inhibitor.
    11. TNBC & other solid tumors [NCT02452424] KEYNOTE-103 trial
    12. TNBC & other solid tumors [NCT02644369] INSPIRE trial
    13. TNBC & other solid tumors [NCT02432963]
    14. TNBC [NCT02622074] KEYNOTE 173 trial
    15. TNBC and/or HER2+ [NCT02178722] KEYNOTE-037 trial. This one includes a IDO Inhibitor.
    16. ER+ & other solid tumors [NCT02331251] PembroPlus trial
    17. oligometastatic breast cancer [NCT02303366] BOSTON II trial
    18. Any invasive breast cancer [NCT01042379] I-SPY 2 trial. Evaluating numerous agents among 1,200 patients
    19. Unknown types of breast cancer [NCT02009449] This one includes AM0010, a humanized version of the immune protein called interleukin-10 (IL-10) - No longer accepting breast cancer patients.
    20. metastatic breast cancer & other solid tumors [NCT01174121] This one involves growing patient-extracted "Tumor Infiltrating Lymphocytes" (TILs).

    This is an update on the Immunotherapy drug "Opdivo" (AKA: Nivolumab, BMS-936558, MDX-1106)
    Like Keytruda (see post above), Opdivo is a Monoclonal antibody and acts as a checkpoint inhibitor, specifically a PD1 inhibitor. It targets the PD-1 protein on T cells (a kind of immune cell). The drug removes the "brakes" (biological blockades) that keep T cells (also called T lymphocytes) from attacking cancer.

    As of Nov 2016, Opdivo is approved by the FDA for 5 different cancers:
    1. Melanoma.
    2. Squamous non-small cell Lung cancer (NCSLC).
    3. Kidney cancer (renal cell Kidney cancer - renal cell carcinoma or RCC).
    4. Hodgkin Lymphoma (for those that relapsed or progressed after autologous hematopoietic stem cell transplantation [HSCT])
    5. Head and Neck (SCCHN) (for recurrent or metastatic squamous cell carcinoma) [Head and neck cancer is a group of cancers that includes cancers of the oral cavity, larynx, pharynx, salivary glands, and nose/nasal passages.] This approval was based on the Phase III Head & Neck clinical trial called CheckMate -141, described here.

    As of Feb 2016, Opdivo is being used in the following breast cancer clinical trials (This may not be a complete list and serves as a springboard to get you started. Please do your own due diligence)

    With the media recently highlighting the remarkable Immunotherapy stories (like here, here, here, and here) of cancer patients achieving "No Evidence of Disease" [NED], I thought it would be wise to remind everyone that Immunotherapy breast cancer clinical trials do exist.
    I found 241 clinical trials open for breast cancer Immunotherapy.
    11 of the 241 are Phase III trials. The rest are Phase I and II trials.

    Here's some resources to find those clinical trials:

    1. Cancer Research Institute's: Immunotherapy "Clinical Trial Finder"
    Call 1-855-216-0127 (toll-free) to reach a Clinical Trial Navigator who will help identify appropriate trials.

    2. NIH Clinical Trials: ClinicalTrials.gov
    The world's largest clinical trials database

    3. Breast Cancer Trials: BreastCancerTrials.org
    Focused on breast cancer. It goes beyond Immunotherapy to include conventional therapies.

    Hi, John!

    I am hoping to be a part of the KEYNOTE-086 trial for TNBC at Emory. Thank you for posting this info. I have been trying to find out more, but have not had much luck. I am going for scans, labs, etc next week, and if all goes well will start treatment the next week. My family and I are very encouraged by what we have been told. Please keep posting any info you may find.I would love to hear from anyone who is in the study.

    Take care--

    Thanks Sue. I'll reply to your PM tomorrow.

    @letmywifelive
    That trial, "Immunotherapy Using Tumor Infiltrating Lymphocytes for Patients With Metastatic Cancer" [NCT01174121], is being run by Dr. Steven Rosenberg at the NCI, who is a bit of a Immunotherapy rockstar.

    The trouble is that this trial only accepts Stage IV patients that have failed "standard" therapies.
    Note the following inclusion criteria:
    "All patients must be refractory to approved standard systemic therapy."
    Specifically, "Breast and Ovarian cancer patients must be refractory to both 1st line and 2nd line treatments and must have received at least one second line chemotherapy regimen."

    I assume your wife wants to avoid chemo. There must be trials that circumvent this requirement. I think it might be a good idea to call the Clinical Trial CRI hotline (855-216-0127) to discover those options.
