Orthopoxviruses (OPXVs) belonging to the Poxviridae family that infect humans are variola virus (smallpox), vaccinia virus (the virus in smallpox vaccine ACAM2000 and smallpox/monkeypox vaccine Jynneos), monkeypox virus, cowpox virus, Akhmeta virus and Alaskapox virus. Since the worldwide eradication of smallpox, the other orthopoxviruses or non-variola orthopoxvirus (NV-OPXV) infections are emerging as a growing public health concern. Currently, there is no treatment approved by the Food and Drug Administration (FDA) for non-variola orthopoxvirus, including MPX. Although tecovirimat is FDA-approved for treatment of smallpox in adults and children, the approved indication is limited to smallpox.

The purpose of this expanded access IND (compassionate use) program is to provide stockpiled tecovirimat for treatment of non-variola orthopoxvirus infections (e.g., monkeypox, vaccinia, or other human virus infection identified as an orthopoxvirus) and secondary treatment of complications from replication-competent vaccinia vaccine in adults and children.

It is also to monitor clinical use of tecovirimat, including any occurrence of serious adverse events, and patient monitoring and outcomes information are also intended to be collected under this expanded access IND program to the extent feasible (e.g., baseline clinical conditions, progression/improvement post treatment, recovered or not recovered from orthopoxvirus infection).

All patient populations, who meet eligibility criteria, can receive tecovirimat treatment under this protocol. This includes children and all adults including pregnant and nursing individuals, and prisoners. Clinical considerations of tecovirimat therapy during an outbreak may evolve depending on the duration and nature of the outbreak and event-based information that may become available during the outbreak.

Tecovirimat treatment may be initiated for 1) patients with laboratory confirmed non-variola orthopoxvirus infection or suspected infection based on known exposure(s) and/or clinical manifestations of disease 2) patients with complications of replication-competent vaccinia infection (e.g., serious inadvertent inoculation with vaccinia, eczema vaccinatum, severe generalized vaccinia, or progressive vaccinia) resulting from vaccination, secondary transmission, or other exposure are eligible for treatment with tecovirimat 3) post-exposure prophylaxis on an individual case-by-case basis in consultation with CDC.

Ineligibility includes 1) patient or legally authorized representative unwilling to sign an informed consent and refuse tecovirimat treatment 2) known allergy to tecovirimat and/or inactive ingredients in tecovirimat 3) for IV tecovirimat only: patients with severe renal impairment (creatinine clearance <30 mL/min).

Adults and children who are unable to take oral therapy or for whom there is a concern that oral drug absorption may be altered should be considered for treatment with IV tecovirimat.

In certain clinical situations, modifications to the dose, frequency, and duration may be necessary depending on the individual patient s clinical condition, disease progression, therapeutic response, and/or clinical judgement in consultation with CDC and FDA as appropriate.

Form FDA 1572 and the CDC patient intake form will be submitted to the CDC within 7 days of initiating treatment with tecovirimat. Any serious or life-threatening AEs and/or medication errors associated with tecovirimat will be reported to the CDC within 72 hours of awareness of the event.

The CDC clinical outcome form and diary form are optional and will be completed if feasible.

Eligibility

INCLUSION CRITERIA:

-All patient populations, who meet eligibility criteria, can receive tecovirimat treatment under this IND program (e.g., children and all adults including pregnant and nursing individuals, and prisoners).

Clinical considerations of tecovirimat therapy during an outbreak may evolve depending on the duration and nature of the outbreak and event-based information that may become available during the outbreak.

EXCLUSION CRITERIA:

-Patient or legally authorized representative unwilling to sign an informed consent and refuse tecovirimat treatment

-Known allergy to tecovirimat and/or inactive ingredients in tecovirimat

-For IV tecovirimat only: patients with severe renal impairment (creatinine clearance <30 mL/min). Oral tecovirimat is an option for patients with severe renal impairment.
