David B. Katague – FDA Chemist and Team Leader
David B. Katague is a Filipino-American chemist who earned a Ph.D. in pharmaceutical chemistry (University of Illinois, Chicago, 1964)davidbkatague.blogspot.com. He spent roughly 20 years in private-sector research (with Chemagro, Shell, Stauffer and Chevron) before joining the FDAdavidbkatague.blogspot.comdavidbkatague.blogspot.com. In industry he published analytical methods (e.g. gas chromatography of pesticides)davidbkatague.blogspot.com. In late 1990 Katague was hired by FDA’s Center for New Drugs (now CDER) as a Review Chemist in the anti‑infective drug products divisiondavidbkatague.blogspot.com.
FDA Career (1990–2002)
Katague’s FDA service spanned 12 years, during which he advanced through several key roles:
1990: Joined FDA as a review chemist (Division of Anti-Infective Drug Products, HFD‑520)davidbkatague.blogspot.comaccessdata.fda.gov. For example, he authored a 1996 chemistry review memo for Vagistat-1 (tioconazole) listing himself as “Review Chemist, HFD-520”accessdata.fda.gov.
1994: Promoted to Expert Regulatory Scientist (GS‑14), specializing in anti‑malarial and anti‑parasitic drug productsdavidbkatague.blogspot.com. (He noted that only 7 of ~90 FDA review chemists held that rank.)
1997–98: Elevated to Chemistry Team Leader for the Division of Anti‑Infective Drug Products (Center for New Drugs, FDA)davidbkatague.blogspot.comdiscover.hubpages.com. In this leadership role he supervised six chemistry reviewers (five with Ph.D.s) and managed all CMC reviews for new anti‑infective NDAs. His responsibilities included prioritizing and assigning review work and ensuring the technical accuracy of all chemistry, manufacturing and control issues for Division applicationsdavidbkatague.blogspot.comdiscover.hubpages.com.
2002: Retired in December 2002 as Chemistry Team Leaderdiscover.hubpages.com. (He was the first Filipino-American to hold that position in the Center for New Drugsdiscover.hubpages.comdavidbkatague.blogspot.com.)
Key Achievements and Publications
During his FDA tenure and career, Katague earned several honors and made notable contributions:
Trailblazer: Katague is described as “a trailblazer in the field of Chemistry and Drug Regulation,” notably the first Filipino-American to attain the position of Team Leader and Expert in the Center of New Drugs, FDAdiscover.hubpages.comdavidbkatague.blogspot.com.
USP Council: He was elected to two consecutive five-year terms (1995–2005) on the United States Pharmacopeia Council of Experts, a significant first for Filipino representationdiscover.hubpages.comdavidbkatague.blogspot.com.
Awards: In 1998 he received FDA’s Equal Employment Opportunity (EEO) Award for outstanding leadership and support of minoritiesdavidbkatague.blogspot.com. The same year he was honored with an “Outstanding Filipino-American Senior Citizen Award in Chemistry, Science and Research” by the Philippine-American Foundation of Charitiesdavidbkatague.blogspot.com.
Publications: Early in his career Katague co‑authored a peer-reviewed article on essential oils: “Analysis of the Volatile Components of Ylang-Ylang Oil by Gas Chromatography” (Journal of Pharmaceutical Sciences, 1963)periodicos.capes.gov.br. He also contributed analytical studies in agrochemical research (e.g. co‑authoring a 1978 Stauffer Chemical study on captan residues in cropsarchive.epa.gov). During his FDA career he drafted many regulatory chemistry reviews (now often embargoed) and led CMC evaluations for anti-infective NDAs.

Areas of Expertise
Pharmaceutical Chemistry and Drug CMC: Extensive experience with chemistry, manufacturing and control (CMC) of drug products, especially anti-infectivesdavidbkatague.blogspot.comdiscover.hubpages.com.
Anti-Infective Drugs: Specialized knowledge of anti-malarial, anti-parasitic (and related systemic antifungal) agentsdavidbkatague.blogspot.com.
Analytical Chemistry: Skilled in chromatographic analysis of pharmaceuticals and natural products (as reflected in his early ylang-ylang oil researchperiodicos.capes.gov.br and industrial methods developmentdavidbkatague.blogspot.com).
Regulatory Science: Deep understanding of FDA review processes, policy and quality standards, through his tenure evaluating new drug applications and serving on the USP Council.
Post-FDA Activities and Affiliations
After retiring from the FDA, Katague remained active professionally and in his community:
Resort Manager / Snowbird: He and his wife Macrine divided their time between Northern California and Marinduque, Philippines. In Marinduque he became the owner/manager of a beach resort (“Chateau Du Mer”)discover.hubpages.com. He describes them as “snowbirds” who spend winters in the Philippinesdiscover.hubpages.com.
Writer and Blogger: Katague is a prolific blogger and author on Filipino-American culture, retirement, history and personal memoirsdiscover.hubpages.comdavidbkatague.blogspot.com. His blogs include The Intellectual Migrants, Marinduque Awaits You, Becoming American, Why Retire in the Philippines, and a personal “My Autobiography”davidbkatague.blogspot.com, among others. He has also contributed essays and articles to sites like HubPages (earning a following of thousands) on topics ranging from Filipino heritage to everyday reflectionsdavidbkatague.blogspot.comdiscover.hubpages.com.
Humanitarian Involvement: Katague and his wife have actively participated in medical mission projects in Marinduque, citing the motto “You only have lived if you have touched the life of others”discover.hubpages.comdavidbkatague.blogspot.com. This reflects their ongoing community service in their second home.
Professional Affiliations: In addition to his USP Council service (until 2005discover.hubpages.com), Katague remains connected to the chemical and Filipino-American communities. He was a founder-member of the Marinara Foundation (a Filipino-American organization, per news archives) and has spoken at cultural events. (For example, he was quoted in the Asian Journal as “David B. Katague, Retired Chemistry Team Leader, FDA” in 2022.)

Katague’s career thus spans drug chemistry and regulation at the FDA, scientific publications, and post‑retirement cultural and philanthropic activities. He is recognized for both his technical contributions (in drug review and analytical chemistry) and for paving the way for greater Filipino-American representation in U.S. science and regulatory agenciesdiscover.hubpages.comdavidbkatague.blogspot.com.
