A privately owned, globally focused
investment group

Who We Are

GHK is a privately owned globally focused investment group with its roots in natural gas exploitation. The company has been at the forefront of science and exploration for more than 50 years. True to its history in clean energy, innovation and technology GHK maintains a portfolio of private equity and publicly traded investee companies. GHK’s trading division focuses principally upon commodities, precious metals and foreign exchange.

Robert A. Hefner III founded the company in 1959 to break away from the family’s long history in the “oil business” by focusing the original GHK partnership on the exploitation of America’s vast undeveloped significantly more environmentally benign natural gas. In 2012, GHK sold virtually all of its producing properties as part of Cordillera Energy Partners III sale to Apache Corporation (Nasdaq: APA) and transformed GHK into its present organization.

Our Investment Themes

Our mission is to search out private or public companies and entities in areas of our expertise and interests that are adding value by new breakthrough technologies and have passionate, creative management, excellent business plans and stable platforms for growth and acquire a significant equity position. Our technology holdings range from startup ventures in BioTech and AgTech to energy companies participating in the transition to clean energy. Because GHK operated as a partnership for much of its history, we like to think of our significant investees as partners and are available to add value in any way we can. 

Current Investees & Partners 

Our most notable investment as of May 2022 is a revolutionary BioTech company that we believe has just accomplished a major breakthrough in cancer with its personalized immunotherapy vaccines.

“Our Northwest Biotherapeutics (NWBO) investee “partner” likely has just made one of the biggest breakthroughs in the history of cancer. We know that is a really big statement so why do we at GHK believe that is possible? Because we believe the doors through which major cancer breakthroughs must pass are the human immune system, immunotherapies and personalized vaccines and NWBO has just leaped through those doors with its personalized DCVax vaccine made from your own cells.

You can argue about trial statistics until the cows come home but the bottom line is 1) people living longer 2) quality of life during treatments and 3) the cost of treatments.

 

During NWBO’s 16-year Phase III trial to treat glioblastoma (GBM), one of the most difficult and lethal of all solid tumor cancers 1) more people lived longer 1, 2) it is safe with virtually no side effects occurring and 3) NWBO estimates treatments will cost about half as much as Standard of Care chemotherapy and radiation treatments. So for the first time ever, GBM patients can have hope! And can hope like prayer increase the effectiveness and energy of the immune system? We think so.

 

We are aware we stuck our necks out when we said “possibly one of the biggest breakthroughs in the history of cancer”. So we have listed below our three principle reasons so you can decide for yourself:

  1. After 417 failed GBM trials treating 31,952 patents over decades, DCVax-L is first treatment that gives GBM patients a meaningful chance to live longer, some now living 9 to as many as 19 years and counting.
  2. DCVax was conceived and created not for glioblastoma alone but as a personalized tool of your own immune system to defeat all solid tumor cancers and that’s 90% of all cancers2.
  3. Since DCVax’s creation NWBO has amassed an enormous rich databank containing masses of information on patients, treatments, and DCVax’s use against 15 different solid tumor cancers3 that has not yet been analyzed by artificial intelligence (AI). We believe that in the near future when these vast amounts of data and information are teamed with AI and some of the world’s leading scientists and doctors that future generations of DCVax vaccines and protocols will experience great leaps forward in effectiveness at lower and lower costs for 90% of all cancers.

 

So to sum up, we believe NWBO with its DCVax immunotherapy personalized vaccines has leaped through the doors and will play a vital role in humanities great drive to defeat cancer once and for all.”

On Tuesday May 10th , Dr. Paul Mulholland of University College Hospital London, delivered a summary of the long-awaited DCVax-L Phase III trial data in a presentation at the Frontiers in Cancer Immunotherapy conference held by the New York Academy of Science. Video of the presentation and a copy of the slides can be found here.

 

The trial showed a statistically significant improvement in both the primary and secondary endpoints, overall survival in newly diagnosed GBM and overall survival in recurrent GBM. It is the first systemic treatment to extend survival in patients with newly diagnosed GBM in 17 years and first to extend survival in those with recurrent GBM in 27 years. The trial showed that newly diagnosed patients treated with DCVax-L had a remarkable 228% greater chance of living at least 5 years post-surgery than those patients treated with the current standard of care.

 

PHX Minerals, Inc.

A natural gas focused mineral and royalty company with a near-term strategy to grow its assets in the natural gas sector. The company believes that natural gas is the baseload bridge fuel to clean energy technologies and that demand for natural gas will continue to accelerate. GHK views PHX Minerals as a ninety-five year old financially sound corporate platform with excellent experienced and forward-looking new management that we believe will not only accelerate the company’s near-term growth but guide PHX Minerals in the participation of new energy technologies for America’s clean energy future. www.phxmin.com
