Patients

At H3, patients are our inspiration, purpose and partners in our research and development; all of our efforts focus on both giving hope and working to make a positive difference in our patients’ lives. Clinical programs assess patients’ personal disease characteristics, then leverage rigorous biology and chemistry with continually updated medical feedback to identify the right patient populations who may benefit from our investigational medicines. By involving patients, their caregivers and health care providers in our research, H3 aims to bring clinically meaningful products to market faster and more efficiently.

Diseases We Study

Breast Cancer (ER+, HER2-)

Expand

There are many types of breast cancer and ways to describe them. At H3 the breast cancer studies focus on patients with estrogen receptor alpha (ER-alpha) positive, human epidermal growth factor receptor 2 (HER-2)-negative breast cancer. Both ER-alpha and HER-2 are proteins that may be expressed on breast cancer cells. In patients who are ER-alpha positive/HER-2 negative, tumor tissue may express either a normal or mutated version of the ER-alpha protein without the overexpression of HER-2 protein.1,2 Clinical trials underway at H3 are testing a targeted oral drug, H3B-6545, a selective estrogen receptor covalent antagonist (SERCA). Administered alone or in combination with other cancer therapies, H3B-6545 is in a new class of endocrine therapies designed to inactivate estrogen receptors, thereby targeting breast cancer caused by normal or mutated version of ER-alpha protein.1

Hepatocellular Carcinoma

Expand

Livers cancers are the fourth most common cause of cancer death worldwide. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer with increasing incidence worldwide; in selected countries, a 35% increase is predicted from 2005 to 2030, resulting in over 459,000 new cases annually.3 HCC most often occurs in people with chronic liver diseases such as cirrhosis caused by hepatitis B or C infection or alcohol abuse. Therapy typically is multi-pronged, depending on factors such as tumor stage, liver function, or other medical conditions.4 H3’s HCC study is testing a targeted oral drug, H3B-6527. H3B-6527 inhibits aberrant fibroblast growth factor receptor 4 (FGFR4) pathway activation, identified as a potentially key genetic driver of both tumor development and dependency in a subset of patients with advanced HCC.5

AML/Myelodysplastic Syndrome

Expand

Hematologic malignancies are cancers that affect the body’s blood and lymph system.6 The cancer may begin in blood-forming tissue such as bone marrow or in the cells of the immune system.7,8 H3’s MDS, AML, and CMML leukemia study is testing a targeted oral drug, H3B-8800. H3B-8800 is being investigated as a potential treatment for patients with hematological malignancies through targeting core RNA splicing machinery,6 specifically modulating wild-type and mutant SF3b1 complexes.

Bladder Cancer

Expand

Bladder cancer is the tenth most common cancer worldwide, occurring in men more frequently than women and usually affecting older adults.9 Causes can include smoking or other tobacco use, exposure to chemicals, past radiation exposure, or parasitic infections.10 At H3 the current bladder cancer study is focused on non-muscle invasive bladder cancer (NMIBC), which is a cancer found in the cells that line the inside of the bladder. An investigational intra-vesical therapy, E7766, aims to activate and mobilize the body’s own immune system to fight invading cancer cells.11 Among patients who qualify are those who fail the current first line therapy, Bacillus Calmette-Guerin (BCG).

All agents are investigational. The diseases highlighted are chosen based on ongoing clinical trials and each agent’s proposed site of action and suggested biologic activity. This is not meant to convey conclusions of safety or effectiveness towards these diseases prior to any regulatory approval from a health authority. There is no guarantee that any of these agents will successfully complete clinical development or be available commercially.

Investigational Medication

H3 Biomedicine also supports expanded access to investigational products where there is preliminary scientific evidence to support the use of a product for an indication when it is logistically feasible and when permitted by applicable law.

Expanded access refers to the use of an investigational therapy outside a clinical trial when the primary purpose is to diagnose, prevent, or treat a serious condition in a patient. This is different from a clinical trial, where more comprehensive safety and efficacy data are collected. The intent of an expanded access program is to provide patients with access to investigational medication for serious diseases or conditions where there is no comparable or satisfactory alternative therapy available. We understand the need for expanded access programs, and we recognize the importance of having an appropriate policy.

H3 Biomedicine will consider a number of factors consistent with the US Food and Drug Administration (FDA) and other regulatory agencies’ guidelines when reviewing requests for expanded access.

All individual requests will be evaluated in a fair, unbiased manner, and we anticipate acknowledging receipt of requests sent to clinicaltrials@h3biomedicine.com within five (5) business days.

At this time, H3 Biomedicine believes that participation in one of our clinical trials is the most appropriate way to access our investigational therapies. If you have additional questions, please speak with your physician or contact clinicaltrials@h3biomedine.com.

Consistent with the 21st Century Cures Act, H3 Biomedicine is publicly disclosing their policy on making investigational drugs available for expanded access and may revise this policy at any time. This website and policy will be updated with a hyperlink or other reference to the expanded access record on clinicaltrials.gov after such record becomes active.

 

Additional information for patients and healthcare professionals participating in an H3 Biomedicine Inc. (“H3B”) sponsored clinical trial taking place in the European Economic Area and/or the UK can find more information here.
