Crimson Biopharm Inc. is advancing CM93, a first-in-class brain-penetrant EGFR inhibitor with over 2,000% brain-to-plasma enrichment — redefining treatment for patients with CNS metastases and glioblastoma.
About
Crimson Biopharm Inc. (CrimsonBio) was incorporated in Delaware in January 2018 by Drs. Jean Zhao and Thomas Roberts — both Professors at Harvard Medical School and Dana-Farber Cancer Institute — with a singular vision: to develop transformative, brain-penetrant therapies for CNS malignancies driven by EGFR alterations.
Our lead program, CM93, was licensed from Dana-Farber in 2018. Through rigorous preclinical development, we identified CM93's extraordinary CNS pharmacokinetics, establishing it as a paradigm-shifting candidate for patients with EGFR-mutant NSCLC who develop brain or leptomeningeal metastases, as well as glioblastoma.
"A paradigm shift in CNS-targeted oncology therapeutics."
Founded by HMS professors. CM93 discovered at Dana-Farber and exclusively licensed in 2018.
FDA-cleared IND for glioblastoma. First-in-human trials active (NCT04933422) within NCI's GTN.

Returning to NSCLC targeting EGFRm brain and leptomeningeal metastases.
A novel third-generation, irreversible covalent EGFR tyrosine kinase inhibitor designed to overcome the fundamental limitations of existing therapies — poor CNS penetration and dose-limiting toxicity.
| Property | CM93 — CrimsonBio | Osimertinib (Tagrisso) |
|---|---|---|
| Brain-to-Plasma Enrichment (Kp) | >2,000% | ~100% |
| CNS Penetration vs. Standard | Over 20-fold higher | Reference standard |
| Toxic Metabolites | None detected | AZ5104 (dose-limiting) |
| Maximum Tolerated Dose | 6× higher than osimertinib | Constrained by AZ5104 |
| EGFR Mutation Coverage | Ex19del, L858R, T790M + WT | Ex19del, L858R, T790M |
| Binding Mechanism | Irreversible covalent | Irreversible covalent |
| Active IND | Yes — GBM (NCT04933422) | Approved — NSCLC |
CM93 achieves >2,000% brain-to-plasma enrichment — a pharmacokinetic profile unlike any approved EGFR inhibitor. This extraordinary CNS distribution is driven by a unique combination of active blood–brain barrier transport and favorable passive permeability.
Unlike osimertinib, which forms the toxic metabolite AZ5104 that constrains dose escalation, CM93 produces no analogous toxic metabolites. This substantially widens the therapeutic window, enabling a 6× higher maximum tolerated dose.
CM93's retention of wild-type EGFR activity — combined with its CNS penetration — positions it for both EGFR-mutant NSCLC brain and leptomeningeal metastases and glioblastoma, where EGFR amplification coexists with wild-type kinase domains.

Compliance
Crimson Biopharm Inc. receives NIH funding to further its research and, as required by Section 4.1.10 of the NIH Grants Policy Statement, makes this Financial Conflict of Interest Policy publicly available below.
Contents
The purpose of this policy is to ensure that research funded by the National Institutes of Health (NIH) is designed, conducted, and reported objectively and without bias resulting from Investigator financial conflicts of interest (FCOI). The 2011 revised regulations are 42 CFR Part 50 Subpart F, “Promoting Objectivity in Research,” and 45 CFR Part 94, “Responsible Prospective Contractors,” which set requirements for promoting objectivity in Public Health Service (PHS)–funded research for grant, cooperative agreement, and research contracts, respectively. The regulations and this policy do not apply to SBIR or STTR Phase I applications or awards.
This policy is intended to implement the regulatory requirements for PHS/NIH grants and cooperative agreements per the regulation at 42 CFR Part 50 Subpart F and NIH’s guidance.
Crimson Biopharm Inc. (CBI) (“CBI”, “The Institution”) adopts this policy for all Investigators (as defined below) engaged in PHS/NIH-funded research. It establishes processes to identify, disclose, and manage Investigator financial conflicts of interest to protect research integrity, ensure the safety of human and animal subjects, and maintain public trust in PHS/NIH-supported research.
This policy implements the regulatory requirements provided in 42 CFR Part 50 Subpart F for grants and cooperative agreements issued by the NIH. This policy applies to individuals who meet the regulatory definition of “Investigator” (as defined below) who are planning to participate in or who participate in PHS/NIH-funded research.
For the purpose of these policies and procedures, the following definitions apply:
Financial Conflict of Interest (FCOI): A significant financial interest that the Institution’s designated official(s) determines is related to the PHS/NIH-funded research (i.e., the SFI could be affected by the research or the SFI is in an entity whose financial interest could be affected by the research) and could directly and significantly affect the design, conduct, or reporting of PHS/NIH-funded research.
Financial Interest: Anything of monetary value, whether or not its value is readily ascertainable.
Institutional Responsibilities: The professional responsibilities of an Investigator on behalf of CBI, which may include activities such as research, research consultation and collaboration, product development, product testing and validation, development of datasets, models, or systems, publication and communication of research results, fundraising, business development, and other professional services performed on behalf of CBI. These responsibilities also extend to institutional committee memberships and service on panels such as Institutional Review Boards or Data and Safety Monitoring Boards.
Designated Official (DO): The individual appointed by CBI to solicit and review disclosures of significant financial interests, determine FCOIs in accordance with 42 CFR 50.604(f) and this policy, and develop management plans for identified FCOI.
Institution: Any public or private organization, domestic or foreign (excluding a federal agency) that is applying for or receives PHS/NIH research funding. For purposes of this Policy, the Institution is Crimson Biopharm Inc. (“CBI”), a privately held biotechnology company. CBI’s institutional activities extend beyond the conduct of research and include, without limitation: raising capital and other fundraising (for example, equity and convertible financings, debt, and non-dilutive grants and awards, and related investor relations); business development, licensing, and strategic partnering, including the in- and out-licensing of intellectual property and the negotiation of sponsored-research and collaboration agreements; preclinical and clinical product development; regulatory affairs; manufacturing and supply arrangements; and commercialization. The Institution takes these activities into account, as applicable, when identifying, reviewing, and managing Investigators’ Significant Financial Interests and Financial Conflicts of Interest under this Policy, because financial interests relevant to PHS/NIH-funded research may arise from any of them.
Investigator: The Project Director (PD) or Principal Investigator (PI), and any other person, regardless of title or position, who is responsible for the design, conduct, or reporting of research funded by PHS/NIH or proposed for such funding, which may include, for example, collaborators or consultants. The institution determines who is responsible for the design, conduct, or reporting of PHS/NIH-funded research. The Institution will consider the individual’s role, rather than the title (e.g., senior/key personnel, faculty, MD, PHD, etc.), of those involved in the research and the degree of independence in carrying out the work when determining who is responsible for the design, conduct, or reporting of the PHS/NIH-funded research.
Manage: Taking action to address a financial conflict of interest, which can include reducing or eliminating the financial conflict of interest, to ensure, to the extent possible, that the design, conduct, and reporting of research will be free from bias.
Research: A systematic investigation, study, or experiment designed to develop or contribute to generalizable knowledge relating broadly to public health, including behavioral and social-sciences research. The term encompasses basic and applied research (e.g., a published article, book, or book chapter) and product development (e.g., a diagnostic test or drug). As used in the regulation, the term includes any such activity for which research funding is available from a PHS Awarding Component through a grant, cooperative agreement, whether authorized under the PHS Act or other statutory authority, such as a research grant, career development award, center grant, individual fellowship award, infrastructure award, institutional training grant, program project or research resources award.
PHS-Funded Research: Any activity supported by a Public Health Service (PHS) Awarding Component through a grant, cooperative agreement, or contract, whether funded under the PHS Act or other statutory authority.
PHS: The Public Health Service of the U.S. Department of Health and Human Services, and any components of the PHS to which the authority involved may be delegated, including the National Institutes of Health (NIH).
NIH: The biomedical research agency within the Public Health Service (PHS) that funds and conducts research to improve health and advance scientific knowledge.
Senior/Key Personnel: The PD/PI and any other individual identified as senior/key personnel by the Institution in a grant application, progress report, or other submission to PHS/NIH. For this policy, the term applies specifically to the public accessibility requirement, which mandates disclosure only of financial conflicts of interest held by these senior/key personnel, as described in Section 9.
Significant Financial Interest (SFI):
Exclusions Related to Foreign Financial Interests: Investigators must disclose all foreign financial interests (including income from seminars, lectures, or teaching engagements, income from service on advisory committees or review panels, and reimbursed or sponsored travel) received from any foreign entity, including foreign institutions of higher education or a foreign government (including local, provincial, or equivalent governments of another country), when such income meets the threshold for disclosure (e.g., income in excess of $5,000).
Investigators will disclose their SFIs that are related to their “institutional responsibilities” as defined in the policy.
The disclosure will not be limited to an Investigator’s research responsibilities or their funded research, as this is too narrow in scope and not consistent with the 2011 regulation.
The Investigator SFI Disclosures will be retained by the Institution as part of the record maintenance requirements. Investigators are required to disclose SFIs at the following times:
The CBI President will serve as the Designated Official(s) (DOs) responsible for reviewing all SFI disclosures and making determinations of FCOI. In cases where it is determined that one of the members of the DOs has a disclosed SFI related to the research under review, or where additional independence is warranted, that DO team member will recuse himself from the review and determination. In such cases, the remaining member will serve as the DO. In situations where a DO must recuse himself, the situation will be documented.
Each SFI will be evaluated in relation to every PHS/NIH research application or award on which the Investigator is responsible for the design, conduct, or reporting of research, to determine whether the SFI is related to the funded research and, if so, whether it constitutes a Financial Conflict of Interest (FCOI).
The SFI disclosures will be reviewed as described below:
An FCOI report will be submitted to NIH within 60 days of identifying the FCOI.
The DOs are responsible for assessing the relatedness of SFIs to NIH-funded research and determining when they constitute an FCOI.
Relatedness Test: The DOs determine whether an Investigator’s SFI is related to research under an NIH award. An SFI is considered “related” when the DOs reasonably determine that: (1) the SFI could be affected by the PHS/NIH-funded research, or (2) the SFI is in an entity whose financial interests could be affected by the PHS/NIH-funded research.
Investigator Involvement: The DOs may consult with the Investigator when assessing whether an SFI is related to the research.
Designated Officials FCOI Determination: An FCOI exists when the DOs reasonably determine that the SFI could directly and significantly affect the design, conduct, or reporting of the PHS/NIH-funded research (“significantly” meaning that the financial interest would have a material effect on the research).
When an FCOI is identified, the DO will determine and implement management strategies to ensure the research is conducted objectively. Examples of management conditions include, but are not limited to:
The DOs will communicate the determination and the management plan in writing to the Investigator and will require the Investigator to certify compliance with the management plan.
No expenditures on an NIH award may occur until the Investigator has met all disclosure requirements and agreed in writing to comply with the management plan. The DOs will submit an FCOI report to NIH via the eRA Commons FCOI Module.
CBI will monitor Investigator compliance with the management plan for the duration of the NIH award.
When the Institution’s FCOI policy applies to subrecipient Investigators, the Institution will monitor subrecipient Investigator compliance with the management plan.
As part of this monitoring process, the DO may request and review documentation demonstrating compliance with required FCOI disclosures, including publications, presentation materials, abstracts, posters, and written communications to study personnel. Investigators must provide copies of such materials, including relevant emails or other written disclosures, to the DO for recordkeeping. These records will be maintained to document compliance with the management plan and to support institutional review and audit activities.
FCOI Policy: Since Crimson Biopharm Inc. receives NIH funding to further its research, CBI is required to make the Financial Conflict of Interest (FCOI) policy publicly available. A copy of this FCOI policy is available on CBI’s public website at www.crimson-bio.com, listed under the Navigation section at the bottom of the home page, as required by Section 4.1.10 of the NIH Grants Policy Statement.
Identified FCOIs held by Senior/Key Personnel: Before any funds are spent under an NIH award, CBI will ensure public accessibility by providing a written response within five business days to requests for information about any SFI that meets all three of the following criteria:
When applicable, CBI will make available at least the following information: the Investigator’s name; the Investigator’s title and role with respect to the research project; the name of the entity in which the SFI is held; the nature of the SFI; and the approximate dollar value of the SFI in the following ranges: $0–$4,999; $5,000–$9,999; $10,000–$19,999; amounts between $20,000 and $100,000 by increments of $20,000; amounts above $100,000 by increments of $50,000; or a statement that the value cannot be readily determined by public prices or reasonable fair market value measures.
The written response will note that the information provided is current as of the date of the correspondence and is subject to updates on at least an annual basis and within 60 days of the institution’s identification of a new FCOI, which should be requested subsequently by the requestor.
If CBI uses a publicly accessible website to meet this requirement, the information will be updated at least annually and within 60 days of: (1) receiving or identifying an additional SFI of Senior/Key Personnel related to the NIH-funded research that was not previously disclosed, or (2) a new SFI being disclosed by Senior/Key Personnel joining the project and determined by the DO to be related and an FCOI. Information on SFIs subject to public accessibility will remain available for at least three years from the most recent update.
Prior to spending any funds under an NIH-funded award, CBI will submit an identified FCOI report to NIH, in accordance with the FCOI regulations, for any Investigator’s SFI determined to be an FCOI. CBI will also ensure that the Investigator has agreed to and begun implementing the associated management plan.
CBI will designate an institutional official to act as the FCOI Signing Official (FCOI SO) in the eRA Commons FCOI Module. The FCOI SO is authorized to submit FCOI reports to NIH. FCOI reports are submitted only when an award is active and an FCOI has been identified (i.e., no award means no FCOI report, and no FCOI means no FCOI report).
The NIH eRA Commons FCOI Module User Guide, available at era.nih.gov/files/fcoi_user_guide.pdf, provides instructions for preparing and submitting FCOI reports.
The institution will submit the following types of reports:
Types of FCOI Reports Summary Chart for NIH:
| Report | Content | Required When |
|---|---|---|
| New FCOI Report (Initial Submission) | Grant number; PI; name of entity with FCOI; nature of FCOI; value of the financial interest (in required increments); description of how the financial interest relates to the research; key elements of the management plan. | (1) Prior to the expenditure of funds on a new award; or (2) within 60 days of identifying any new FCOI during the award period. |
| Annual FCOI Report | Status of the FCOI (whether it is still being managed or no longer exists) and any changes to the management plan, if applicable. | Submitted annually at the same time as the annual progress report, multi-year progress report, or at the time of a grant extension. |
| Revised FCOI Report | Updates to a previously submitted FCOI report to describe actions that will be taken to manage the FCOI going forward, or to revise the original report. | Following a retrospective review when noncompliance with the regulation is identified, if applicable. |
| Mitigation Report | Project number; project title; contact PI/PD; name of Investigator with FCOI; name of entity with FCOI; reason for review; detailed methodology, findings, and conclusions. | After a retrospective review when bias is found. |
Each Investigator will be informed of CBI’s FCOI Policy and trained on their responsibility to disclose foreign and domestic SFIs under this policy and the FCOI regulation at 42 CFR Part 50 Subpart F. Training must be completed before an Investigator engages in PHS/NIH-funded research, at least once every four years, and promptly when any of the following occur:
To supplement the regulatory training requirements, CBI will utilize NIH’s training programs to train Investigators, who are required to complete either: (1) the NIH Training module and print and retain the Completion Certificate for audit purposes, sharing it with the DO, or (2) the NIH Virtual Seminar presentation on FCOI compliance, sending the DO the date of completion by email for audit purposes.
If CBI identifies an SFI that was not disclosed, reviewed, or managed in a timely manner, the DO will, within 60 days: review the SFI; determine whether it is related to NIH-funded research; determine whether it constitutes an FCOI; and, if so, implement an interim management plan describing actions that have been and will be taken to manage the FCOI going forward. CBI will also submit an FCOI report to NIH via the eRA Commons FCOI Module.
Whenever an FCOI is not identified or managed in a timely manner — including (1) failure by the Investigator to disclose an SFI later determined to constitute an FCOI, (2) failure by the institution to review or manage an FCOI, or (3) failure by the Investigator to comply with an established management plan — CBI will, within 120 days of identifying noncompliance: (a) complete a retrospective review of the Investigator’s activities and the NIH-funded research to determine whether the research, or any part of it, was biased in the design, conduct, or reporting; and (b) document the retrospective review in accordance with 42 CFR 50.605(a)(3)(ii)(B). Based on the results, if appropriate, the Institution shall update the previously submitted FCOI report, specifying the actions that will be taken to manage the FCOI going forward.
If bias is found, CBI will promptly notify NIH and submit a mitigation report as required by 42 CFR 50.605(a)(3)(iii), including the impact of the bias on the research project and the plan of action or corrective steps taken to eliminate or mitigate the effect of the bias.
CBI will thereafter submit FCOI reports annually to NIH as required by the regulations and the terms and conditions of the award. Depending on the circumstances, CBI may implement additional interim measures regarding the Investigator’s participation in the research until the retrospective review is complete.
If bias is not found following completion of the retrospective review, no further action will be taken unless new information is discovered that needs to be reported to the NIH. If applicable, the Institution will update an existing FCOI report to specify the actions that have been, and will be, taken to manage the FCOI going forward.
If the failure of an Investigator to comply with an Institution’s FCOI or FCOI management plan appears to have biased the design, conduct, or reporting of the PHS/NIH-funded research, the Institution shall promptly notify the PHS/NIH Awarding Component of the corrective action taken or to be taken. The PHS/NIH Awarding Component will consider the situation and, as necessary, take appropriate action or refer the matter to the Institution for further action, which may include directions on how to maintain appropriate objectivity in the PHS/NIH-funded research project.
If HHS determines that a PHS-funded clinical research project evaluating the safety or effectiveness of a drug, medical device, or treatment was designed, conducted, or reported by an Investigator with an unmanaged or unreported FCOI, CBI will require the Investigator to disclose the conflict in every public presentation of the research results and to request an addendum to previously published presentations.
A subrecipient relationship exists when federal funds flow from or through CBI to another individual or entity that will carry out a substantive portion of a PHS-funded research project and is accountable to CBI for programmatic outcomes and compliance.
Subrecipients (e.g. collaborators or consortium members) are subject to CBI’s terms and conditions. CBI will take reasonable steps to ensure that all subrecipient Investigators comply with the federal FCOI regulations at 42 CFR Part 50 Subpart F. CBI will include in each written agreement with a subrecipient terms specifying whether CBI’s FCOI Policy or the subrecipient’s own FCOI policy will apply to subrecipient Investigators.
If the subrecipient’s FCOI policy applies: The subrecipient institution must certify in the agreement that its policy complies with federal FCOI regulations. The agreement will specify the timeframe for the subrecipient to report identified FCOIs to CBI in time for CBI to meet NIH reporting deadlines (i.e., before funds are spent and within 60 days of the subrecipient identifying an FCOI). Typically, this means requiring subrecipients to report FCOIs to CBI within 50–55 days of identification. CBI’s DO will then submit the subrecipient FCOI report to NIH through the eRA Commons FCOI Module.
If the subrecipient cannot certify compliance: The agreement will specify that CBI’s FCOI Policy applies. In this case, subrecipient Investigators must disclose their SFIs to CBI, directly related to the subrecipient’s work for CBI. The agreement will allow sufficient time for CBI to review, manage, and report any resulting FCOIs. When an FCOI is identified, CBI will implement a management plan, monitor compliance by the subrecipient Investigator, and submit the required FCOI report to NIH via the eRA Commons FCOI Module.
CBI will maintain records of all Investigator financial interest disclosures, CBI’s review and response to those disclosures (whether or not they resulted in a determination of an FCOI), and any actions taken under this policy or through retrospective review. These records will be retained for at least three years from the date of submission of the final expenditures report, or for longer periods as specified in 2 CFR 200.334, for different situations. CBI will retain these records for each competitive segment as required by regulation.
Copies of management plans will be retained as part of the record maintenance requirements and not submitted to the NIH per NIH’s FAQ guidance.
Compliance with this policy is a condition of employment and/or participation for all applicable Investigators. Failure to comply with this policy, including failure to disclose Significant Financial Interests, failure to comply with a Conflict Management Plan, or failure to complete required training, may result in appropriate corrective or disciplinary actions.
Such actions may include, but are not limited to, formal notification or disciplinary measures, restrictions on participation in research activities or use of research funds, suspension or termination of employment or contractual relationship, and/or disqualification from participation in Government Award–funded research, as appropriate.
In addition, CBI will take all actions required under applicable federal regulations and sponsor requirements, including conducting retrospective review, implementing mitigation measures where necessary, and notifying the sponsor when required.
The PHS/NIH Awarding Component and/or HHS may inquire at any time before, during, or after award into any Investigator disclosure of financial interests and the Institution’s review of, and response to, such disclosure, regardless of whether the disclosure resulted in the Institution’s determination of an FCOI. The Institution will submit, or permit on-site review of, all records pertinent to compliance with the regulation and this policy. To the extent permitted by law, HHS will maintain the confidentiality of all records of financial interests. On the basis of its review, the PHS/NIH Awarding Component may decide that a particular FCOI will bias the objectivity of the PHS/NIH-funded research to such an extent that further corrective action is needed, or that the Institution has not managed the FCOI in accordance with the regulation or this policy. The PHS/NIH Awarding Component may determine that imposition of specific award conditions under 2 CFR 200.208, or suspension of funding or other enforcement action under 2 CFR 200.339, is necessary until the matter is resolved.
